Anyone still have floppy punches for sale. I'm interested in acquiring
one.

floppy media, so no need to punch holes.

I still have a few but if Norberto is not expecting to use his, it is OK
to get it from him.
I am over loaded with 16 hole punches as well for anyone that
might want one.

If you have spares, then I will hold to the one I have.
In another subject, can you check the price in building a small bracket to hold in place 4 half height H8 boards? (Z80 CPU, H37, H67 and Z67-IDE).
Eventually I will like to add the same footprint to all the half height boards that I have on the H8-Z37 to hold the Heath heathsink in place.
Thanks,
Norberto

I didn't contact the machinest directly I did it through
Chris Elmquist to a friend of his.
You can contact him.
It was basically my design with a few modifications to make
it manufacturable at around the target price.

Yes-- I worked with an old friend who has a professional prototype
machine shop in his garage to build both the H8 brackets and the 10-
and 16-hole hard sector floppy punches.
I'm not sure I completely visualize what sort of bracket you are
interested in Norberto so we can chat off the list to come up with a
design that I can then run past my buddy for pricing. Of course for
him, it all depends on quantity desired too so we'd also have to know
how many we want to build up front.

I got the punch from Dwight today. Cool toy. I rummaged around downstairs and found a couple boxes of new old stock Verbatim DS/DD soft sectored disks I bought somewhere along the line for 88 cents a box (they still have the price tag). that’s less than 9 cents a disk! A lot better than paying $35/box.
By the way Athana still has both hard and soft sectored 5-1/4” diskettes if you’re willing to pay the price! (I bought a box from them a while back and they’ve worked fine):
Hello Mr.Glenn,
Thank you for your inquiry about 5.25" DS/DD & 5.25" hard sector

Since all of the images in Les’ library are in the original “100k” format it’s still useful to be able to read/write them and download via the H8D utility.

There are two client codes. One is for the 8251 and the other
for the 8250 serial chip.
I don't think it makes a difference if it is a Z80 or a 8080.
There might be timing issues, though.

I cannot get Les’ H8D utility to work with the new Z80 CPU board. Does it works with the Heath Z80 board? I still have my 8080A CPU, that I can use. I rely heavily on the SVD board to deploy the H8D images.

I was careful in following the instructions to punch the soft sector diskette and after I was done, it worked very nicely. I was able to format, copy files and boot from it. Now I need to get more soft sector diskettes which will allow me to bundle the images that Ken created to support the Z67-IDE board.

It does not work for me on the Z80. I can only run it on my old (8080) system. I don’t think it’s timing. I seem to recall that when I looked at it (briefly) I concluded that maybe the low level vectors to the H17 ROM entry points weren’t getting initialized???. From this I concluded it was a ROM issue, maybe the PAM-37 ROM doesn’t do the same low level initialization?
I never got back to look further. It is annoying though… maybe I’ll take a look tonite.

This topic was going about six months ago, and I think someone posted that they got it working by disabling one of the ROMS. I go back to see if I can find it. I hadn't gotten too deep into the H8 yet, so just filed it as a mental note. I should know better, my fergitter is my best working part!.

Since the code is designed to run without an OS it relies on the ROM routines (see below). Using the front panel on my Z80 system I examined these addresses. They seem to all contain either all 1’s or all 0’s. even if I attempt to boot it doesn’t fill them in.
On my 8080 system I clearly see executable code there.
What’s confusing is that the PAM-37 definitely makes calls to these entry points. I can see it in the source listing..
I’ll keep poking…

Ok I lied J. I didn’t let the boot go far enough. If I actually boot an HDOS disk it DOES load in the vectors.
Now too bad I can’t try the H8D utility because I can’t boot my XP system since I messed that up when I loaded Linux.

Fixed the boot problem on my dual-boot (XP/Linux) box by running update-grub2. easy.
When I try to run the H8D utility (connecting to my Z80 system) it gets pretty far. Senses the client software running on the H8 but when I try to send I get a serial port timeout. Except for the little ribbon cable going to the H-8-4 I’m using the same cable (as works with my 8080). I suppose I could swap the H-8-4 card and ribbon cable with the working setup to see if that’s the problem… but not tonight, it’s getting late.

I believe that we toggle a bit in the user port (F2h) .CTL2FL to switch from RAM to ROM addressing for the lower block.
If you could boot XP up to the point of installing Linux and just cannot boot it because of the boot loader (probably GRUB), then it is repairable. The mechanism is somewhat dependent on the distro and version of GRUB.
I'm just guessing here, but you probably resized the XP partition and created a new partition for Linux in the freed space. If you did not write to the XP partition during the install, you should be able to recover.
You need a Win XP install disk, not necessarily for your computer. You need to search Microsoft.com for repairing / restoring the boot loader for Win XP. That should get Windows booting, but now you won't have Linux. Boot a live CD and perform the GRUB install for your distribution. It should have a 'HOW_TO" for this situation.
If you get this far, we can talk some more about getting you DOS capability in XP as well so you can run TELIX and various other DOS programs that work well for supporting your Heath.

Mark Garlanger
Maybe I remembered it wrong, from a cold start, can you try the boot command without any disk in the drive, and let it time-out then check to see if the values are valid? The procedure is suppose to work for someone that has nothing to boot. It's important to be able to get started without any valid disks.
Also, did you know that once you get it working, there is an option to create a disk that you can just boot? Booting the disk will initialize the 8-bit system and it will be ready to talk to your XP machine. Nothing appears on the screen, but that way, you don't have to enter the program every time. And since it's booting, those addresses should be valid.
Mark
Glenn Roberts
Tx mark. What works is if I put in a bootable HDOS disk and boot to the point where I get <BOOT> on the screen, then interrupt it (from the front panel). Then at that point the H17 disk i/o vectors are set in RAM. Yes I created a boot disk that has the client software on the boot track and that installs instantly. So that part’s working great.
still getting a timeout on the serial port when I run but that could be a port setting or cable issue. I’ll check that next.
Thanks!
Dan Emrick
When you get things working with XP, I have a utility that I'd love for you to try on Linux. Right now it uses USB and looks for the FTDI USB adapter but I can probably modify it for serial port use.
If you're still using Debian, I'll test it out on a Debian system before sending it to you. I'll need some lead time to convert it to serial I/O so let me know if you're are interested.

When keying in the code, we first need to load the H17 ROM into memory so the short program code can use the ROM routines. That is accomplished by the incomplete boot of an H17 device. (The computer switches the user port to map in the ROM instead of RAM in the low memory.)
Once we have the basics in place to provide communication, we have the option to have the program on the PC to send write commands to write track 0 to make the loader disk so we don't have to manually do this process again. Booting the loader disk causes the computer to load the tables to boot, but the code in the boot track is just what is needed to communicate via the serial port which then goes into it's loop by gracefully exiting the boot process. It responds to two instructions basically -- "Read and Send by track" or "Receive and Write by track".
Another piece that may be confusing people is that the loader code keyed in is different for an H8 and H89. Also, If the loader code precedes Les' Z80 board with the dual ROM setup, it may be a bit less than adequate and need a minor revision.

Hey guys...I wasn't really following this, but this jumped out at me.
Dan, you know the FTDI chips have excellent direct support under
Linux, right?

Yep, there are two "driver" packages that provide access to the FTDI device from Linux. One is proprietary provided by the company and the other open source. I've been using the company provide version with great success.
