I was checking the files and I see that I did modify such card to V1.2 and website calls for V1.1. As the schematics are not linked to the PCB board as I did it manually, I hope that there are no layout mistakes. It will take time to review for layout mistakes.

I will order 10-pcs once the layout is verified. 

Thanks,
Norberto

I have been working on this board schematics as they were not linked to the board layout and did not want to make a layout mistake by adding some improvements. I just finalized it and will order boards after X-mas is over.

So the space for the Sparkfun FT245 breakout board could be eliminated if you like. The board was retired some time ago

https://www.sparkfun.com/products/retired/7841

 

may not be worth the effort though. Your call.

 

Longer version:

 

At the time these boards (this one and the companion H8 board) were designed the group was experimenting with two approaches to USB connectivity. The 24-pin socket to the right holds an FTDI VDIP1 which can do USB host protocol, allowing for flash drives, printers and other devices to connect. In this mode the H8/H89 is the USB “host” with the heavy lifting of the USB protocols all built into the processor on the VDIP1.  I wrote some simple utilities to copy files to/from the flash drive (I’m currently baselining/documenting that code – more soon on that!. Earlier versions of my code are on Norberto’s site http://koyado.com/Heathkit/H-8_USB.html)

 

The FT245 breakout board sported an FT245RL chip which implements the “slave” side of the USB protocol.  In this mode the H8/H89 must be plugged into a host computer.  The host sees the H8/89 essentially the same way it would a disk drive or flash drive. All of the file transfer functionality is implemented in software on the PC side. Dan Emrick and Chris Elmquist did some innovative work with this: http://danemricksite.net/HeathkitProjects.php#USB/H8D

 

The Sparkfun breakout board is no longer available but the VDIP1 is still available (Mouser, Digikey…). FTDI has also come out with a newer version of the VDIP based on their VNC2 chip series, but we’ve seen little compelling reason to change our designs.

I thought the FT245R presents a "tty device" to the host PC. It is strictly serial communications, as far as I can tell. What you do with that serial communications is another matter, but the PC sees a COM/TTY device, not storage.

That is great news for the H88/H89/Z90 to keep going. Can you add my name to order one piece of board?

I was planning to add support for the FT245R as another serial port, so that we don't lose the "modem" port at 330Q when the VDIP1 is installed. But, it seems we don't consistently have an FT245R with every VDIP1 (i.e. new Z80 CPU boards only have VDIP1) so it didn't make as much sense to do that. I'm not suggesting any changes about that, but it was a use I considered, briefly. The FT245R looks nothing like an INS8250, but it is pretty simple and so could be put into drivers as a one-off. Given the INS8250 has a "scratch pad" register, one could possibly even auto-detect whether 330Q is an INS8250 or FT245R.

But if the part is obsolete, it may make even less sense. Of course, just because SparkFun no longer makes it doesn't mean FTDI no longer makes it.

For the H8, should we add the FT245R on a tiny board? Or should I added it to the single H17 controller which is almost done? The single H17 controller has the VDIP1 already installed.

I just found out that this part is out of stock. So, it is not available. I think it makes sense to add a tiny board with surface mount parts if we agree that is needed.

Alternatively, replace the current DIP-style footprint with the DIL end-connector style that’s readily available on eBay.

Example: https://www.ebay.com/itm/384504988953

 

Also available at, e.g.,: https://pmdway.com/products/ft245-usb-to-parallel-fifo-breakout-board

 

My vote goes to keeping the FT245RL but with the DIL end-connector footprint.  The pin-out is specified on the PCB:

Example connector: https://www.taydaelectronics.com/2x10-pin-2-54mm-dounle-row-right-angle-female-pin-header.html

Sparkfun footprint = 1.5x0.92" = 38mm x 24mm

 

BOB footprint is 46mm x 30mm.  Extend length for the right-angle DIL socket.

 

So it’s not a slam-dunk to adopt the replacement board from the perspective of board layout.

Not sure if I really have a place in this discussion given that I do not have an H8.  Even so, I use the FT245 capability of the H89 USB-Serial board in my H89 and my H89-SBC.  Of course, I'm just a little prejudiced having worked with Chris and others on the HDOS driver early on.  The PC side is a custom program that makes H8D images available (currently up to 4) for mounting via the FT245 interface just as a spinning floppy would be.  I use Linux but experimented in the past with a version for  MS Windows.  It's written with the Qt IDE.

My two cents:  I support Paul's recommendation to keep the capability even if it requires a modification to handle the different B/O board configuration (which I did use in early H89 prototypes).

Before I forget, thank you, Norberto, for all that you've done and continue to do to preserve and enhance these beloved old boxes and our enjoyment of them.

Merry Christmas and Happy Holidays to all.

I suggest you put it on the shelf for now. There are serious parts shortages not only for chips but many other components. The problem is due to pandemic incidents. A huge mistake in the USA is to allow companies to use overseas for cheap labor. Now, the US has to restore local electronic businesses which may take a few years.

I did receive the FT245R breakout board. It took about 11 days to get. I will play with the parts placement to figure out cable and parts best location. I'm still waiting for the 2x 10 pin connector which I forgot to order last month. It should be here within the two weeks.  Once I get the 2x 10 pin female connector, I should be able to order some boards to check the layout and board operations. I do not expect any issues as it is based on previous board schematics.

I will work with Todd to fulfill the needs for those that requested such board once I get a fully operational board.

In this mode the H8/H89 is the USB “host†with the heavy lifting of the USB protocols all built into the processor on the VDIP1.  I wrote some simple utilities to copy files to/from the flash drive (I’m currently baselining/documenting that code – more soon on that!. Earlier versions of my code are on Norberto’s site http://koyado.com/Heathkit/H-8_USB.html)

 

The FT245 breakout board sported an FT245RL chip which implements the “slave†side of the USB protocol.  In this mode the H8/H89 must be plugged into a host computer.  The host sees the H8/89 essentially the same way it would a disk drive or flash drive. All of the file transfer functionality is implemented in software on the PC side. Dan Emrick and Chris Elmquist did some innovative work with this: http://danemricksite.net/HeathkitProjects.php#USB/H8D

 

The Sparkfun breakout board is no longer available but the VDIP1 is still available (Mouser, Digikey…). FTDI has also come out with a newer version of the VDIP based on their VNC2 chip series, but we’ve seen little compelling reason to change our designs.

Thanks Pat!

 

Did some measurements and for now it looks like this until I get the 2x10 pin female connector. Also I added the 3.68MHz osc to run the serial ports at a higher baud rate as an option.

Great to see discussion/interest in the h89. We’ve been talking a lot about h8 in recent months…


Still not sure if we’ve got any use cases lined up for the ft245 when we get it? We could dust off Dan Emrick’s file sharing software for Linux. Not sure where that lives or the state of it, or level of interest… Douglas was originally interested in using the 245 as a high speed serial port I believe. That would take some software work to accomplish.

I’m away from my systems (helping my son get set up in new apartment) but will be getting the software/documentation for the VDIP side done as soon as I can when I return…

I did a CP/NET client for the FT245R, although I'm not sure if anyone has tried it out on a real H8/H89.

Norberto and I also kicked around an idea for a "major" expansion to the H89, picture attached. We didn't get any further than this drawing (based on some clearance experiments by Norberto), but it is looking like it would work.

Douglas is in the "To-Do-List"; H89_Mezzanine. I worked on it for a while on the mechanical pins aligments, clearance, and then I switched back to the H8. It will be a great board addition to the H89.

Received today the 2x10 pin female connector and everything looked fine until I put the FT245R board on a real wire-wrap board. This board was design to be attached to the outside of the board and not on top of the board. The solder underneath the board along with the pins for the 2x10 pin male header, will force the board to lifted at an angle when inserted on a wire-wrap board. The solution will be to cut a hole underneath the board to released such pressure.

 

Here are some photos which described better the issue. I’m open to other ideas to fix this issue.

 

Looks good so far! 😊

Hole in the board seems rather drastic. Are you using a high profile right angle connector? What dimension would you need to make it work? What is your source for the ft245 breakout board? Is it available without the pre-attached header? A straight header would be better for this application.

Not to kick up any more dust on the matter, but there is this module:

https://www.mouser.com/ProductDetail/FTDI/UM245R?qs=Xb8IjHhkxj4TWAlYgWlsig%3D%3D

Which is a more conventional mount, albeit more expensive (2.5x).

As Glenn said, might be worth contacting WaveShare and see if they can supply without the header mounted. That was a nice thing about AdaFruit, at least in my experience - they ship their modules with the header separate.

Can you first use a 2x10 straight DIL header (or two SIP headers side-by-side), and then plug the right-angle 2x10 DIL connector into that?

The FTDI board might also have a bit more longevity.  I wonder if the WaveShare board will disappear after a year just like the Sparkfun one did?  For that matter, will WaveShare itself be around long term? The FTDI VDIP1 board has been available for a very long time now…

 

I know we’ve mostly stuck to through-hole construction on our boards, but another option could be to surface mount the ft245 chip on the board… the Rev 1.1 USB board for the H8 has this option

A thought that might make the cutting easier (cheaper)   would be to shift it enough that you have a 3 sided opening in the edge of the board rather than a 4 sided hole that has to cut separately..

Thanks, Steve, for your feedback! That is a better idea.

As Glenn mentioned, I added surface mount to the H8-USB board as it was difficult at that time to get the AdaFruit board! 

Glenn, thanks for the reminder as I forgot about it. I decided to go with the surface mount part as it will provide "longevity" to this board which is what we want. I will ask the pcb manufacturer to install such component at the factory depending on price. If not, then we will need someone to help us solder such part to the board or provide instructions on how to do it easily ourselves.

I did try that last night, but the connections are weak as the pins are not long enough to make good contact. This can cause the board not to work as the contacts are weak.

And I may be wrong but I suspect the majority of users will be more focused on the VDIP USB solution, so not every board will need the FT245 installed.  Good idea to inquire about factory install. 

 

I’ve recently become less leary of SMT components. I notice even some of the hobby magazines are featuring projects with SMT (e.g. Silicon Chip [Australia]). I got a lesson in the basics from the guy at the next booth from us at VCF.  I guess PC board mfgrs can also provide a solder/flux mask to help with parts placement and then you pop the board into a modified toaster oven. I know I’m oversimplifying, and many of you out there are undoubtedly expert at this.  Still, we likely won’t be able to rely forever on through-hole technology and breakout boards…

I will remove the right-angle connector on this module so that it can mounted at a straight angle. That will give us the capability to use this module or add the surface mount part as well. Two possible solutions better than one. Removing the right-angle pins from this board will be much easier. I will give it a try tomorrow.

Ugh! :-/

I am happy to help people get started with surface-mount. I even do
it before breakfast. =)

Actually we probably will, if history is any indicator. There's an
extremely widespread perception that SMT is somehow "new" and
through-hole is somehow "obsolete". Well, you can get through-hole
7400s all day long from first-line (i.e., above Jameco etc)
distributors, and surface-mount parts have been around, and common,
since the 1960s.

There's also an extremely widespread irrational fear of surface-mount
parts. I think a lot of that stems from people rushing in without
thinking (or listening) and destroying things. No, you cannot use your
bought-it-at-Radio-Shack-in-1980-for-$7 soldering iron. No, you cannot
use your huge 1/8" diameter wire solder. And no, the standard muscle
memory soldering expertise that you've had for decades. It is a
DIFFERENT PROCESS that requires different tools and skills.

When people rush in and try to use their existing tools and
expertise, things go to hell pretty quickly. The first bit of advice
that I have is to slow down, take your time, and learn about how it all
works. Then get the proper tools, then start to develop the expertise.
You know, just how we all learned through-hole soldering decades ago!

I made this "transition" about 25 years ago. It didn't take long for
me to start hating through-hole construction. It takes forever by
comparison, constant flipping over of boards, burnt fingers, crazy
contortions to hold components in while you get one pin soldered, etc
etc etc. All of that BS is gone with surface-mount.

As a commercial designer, the only time I design with through-hole
parts now is for connectors which will see a lot of physical stress.
Beyond that, I avoid them like the plague.

If I can handle it, anyone can.

Are we going to do the H89 USB/serial card order like the others lately?  Todd Goodman will have a batch made up and then post a note here?

 

If so no need to orchestrate a “pre order” list.  just wait for the announcement from Todd… is that our process ?

Also, I’m going to move the logic around so that I can get more free real state by using the same layout as in the MMS Corvus board. See attached picture.

 

The USART’s on the right and the VDIP1 and RT245R on the left.

So it’s not a slam-dunk to adopt the replacement board from the perspective of board layout.

Seems to be in-stock at https://www.canakit.com/breakout-board-for-ft245rl-usb-to-fifo-bob-07841.html

 

Alternatively, replace the current DIP-style footprint with the DIL end-connector style that’s readily available on eBay.

You can use either use the FT245R breakout board with the 10-pin connector or the surface mount part with the USB-A connector. Once the USB-A male connector is installed, you cannot use the breakout board. I will suggest to use the breakout board with the 10-pin connector and when they go obsolete you can switch to the surface mount part if needed.

Norberto mentions the USB A connector – here’s a little more info.

 

The FTDI VDIP-1 controller board that we have used from day 1 on these boards includes an ability to talk to two USB ports. Port 2 is the one built into the board itself:

 

But Norberto has always provided a place to mount a second “A” type connector to interface to Port 1.

 

The VDIP firmware we’ve been using is called “VDAP” and is documented here https://ftdichip.com/wp-content/uploads/2020/08/UM_VinculumFirmware_V205-1.pdf  It contains a rich command set that we haven’t completely tapped into.  The main commands we’ve used involve access to USB flash drives on Port 2 but you can also connect a range of devices to port 1 including hubs, printers and “human interface devices”.  To my knowledge none of us has experimented with this but it does offer up lots of possibility.  For example, the ability to attach a USB printer to your system.  Or what about a mouse or keyboard?  As usual it’s a “small matter of programming” to figure out how to do this.

 

So when considering whether or not to add the second USB connector to your build just remember that there are some possibilities that we can explore here when one of us has the time to dig into this! So far on all the boards I’ve built I’ve chosen to add the connector since it involves only a few parts, but on the new board it sounds like there may be an issue if you need the FT245 interface board.

The above is only true with the FT245 and not true for the VDIP1. The board supports both USB ports for the VDIP1 at the same time.

That's up to you and Terry; I don't mind doing all of them if
desired, if Terry isn't comfortable with it. Remember that I have a
full assembly setup here; I do this for a living. (but free for stuff
like this, of course)

After adding the FT245R surface mount part and the FT245R breakout board, the data bus go messy, so I had to removed the high speed OSC for the USART. I used such space to add a data buffer to isolate the data bus. This will also improve the reliability of the board and H89 computer.

 

This is how it looks now with the data buffer.

Thank you for the continued progress on this :-}.

I see that you snuck in a SSOP-28 (ouch!) footprint for a “naked” FT245R; I presume that goes with use of the “FT245R1” USBA_3 footprint?

Will you be soldering one up and testing that alternative to the daughterboard?

The plan is to solder the SSOP-28 part into the board and to test via USB-A. The micro USB-C breaks easily as it is surface mount as well.

Hello Dave,

 

The H89-USB boards will be here by next week. I will like to send you 2xboards to solder the surface mount FT245R IC. I will send the following parts so that you can test it with a laptop. The laptop should power up the IC and should be detected by the Windows device manager.

 

Sending:

2x pcb boards

2x jumpers to power-up the IC (soldered)

2x FT245RL surface mount

1x USB Mini Cable to test IC with laptop  or PC.

2x Mini USB adapter (soldered)

 

Just email me your shipping address, to send the above parts. You can keep one of the boards if interested as I just need one for functional verification.

 

Thank you for your help,

Norberto

I’m not sure how the FT245R is being powered (USB vs. local) but the following point was recently made in another forum – although I expect that it is less relevant here.  Still, FYI:

 

“I _always_ use bus power for those modules wherever possible, mainly so that power cycling the target system doesn't make the host system think that the serial port has gone away and come back. That serial port "flap" almost always requires manually telling whatever software you're using on the host to reopen the port, or running it again from scratch. That's not a big concern if you don't anticipate power-cycling the target, but somehow I often wind up having to do that.”

 

I note that the typical FT245R-based mini-boards usually include a 1x3 jumper-block to make the choice, and the USB-choice brings additional line-protection circuitry to bear.

There's no Windows here, but I can test it with Linux.

Good point and thank you for sharing such information. Powering the FT245 ONLY FROM THE USB port is a big mistake. In our case we power the FT245RT from the H89 side and from the USB side by using a diode on the H89 SIDE (VUSB). The FT245 IC is always powered. If we only power from the USB side, then the following issue will occur:

 

This is to prevent the FT245 from adding too much capacitance to the data bus if the FT245 USB cable is not connected to the USB port on the PC side to avoid data corruption when trying to read from the VDIP1. On the H89 it causes the system to hang on power-on. ”

 

By buffering the data bus on this board for sure we fixed the H89 hang on power-on. The diode prevents the IC  from losing VCC. I do not use +3V, instead +5V.

 

 

Thanks,

Norberto

The H89-USB-Serial board arrived this evening. I just found some minor mechanical problems that I will need to fix, but won't interfere with the operation of the board. The 3-side cut work out fine to install the FT245 board.

Pictures attached.

Hello Dave,

 

I'm  sending you the two H89 boards. To be able to use the smaller USPS box, I cannot solder the parts. I'm sending you the parts to solder. It is a 3-pin header for VCC to the FT245 and a Mini-USB adapter.

 

I will include the MINI-USB power cable.

 

Solder USB-Mini breakout board here: header included.

 

Note: Also figure out the best method to install such breakout part to the board.

 

 

 

Solder 3-pin power header included here + the FT245 surface mount part (JP2)

I just finished the assembly of the H89-USB-Serial board. It is ready for testing. I took out my old friend from storage (H89-SBC) to use it to test it out. This new board looks great.

 

Now to assembled the H8-Z5-4 cassette board.
