A New 68000 CPU Board for the S-100 Bus
|
| |
I would like to mention that Andrew Lynch and I have just completed work on the final 68000 Master/Slave CPU S-100 bus board. For those that have been following progress this has been a long project. It utilizes the 16 bit capability of the 68K CPU on the S-100 bus. The board also accommodates the later 68010 CPU.... more »

Available S-100 board PCBs
|
| |
Hi
If you are looking for some build-it-yourself S-100 PCBs, I have
several available. There are S-100 IDE V2, S-100 LAVA, S-100 bus
terminator/prototyping board, and some S-100 68K CPU board PCBs.
Please contact me at LYNC...@YAHOO.COM if interested. Thanks and have
a nice day!

An 80386 CPU board and RAM board for the S-100 Bus - possible use for CPM 86 programming
|
| |
I would like to mention that Andrew Lynch and I have just completed work on the final prototype (V4!) of a new 80386 Master/Slave CPU S-100 bus board. This board is capable of reaching up to36MHz for its clock input when used with RAM on its daughter board (see below). For those that have been following progress this has been a long project. It utilizes the 16 bit mode of the 80386 to address up to the 16MG of RAM the S-100 bus is capable of addressing. A second daughter board system with two overhead ribbon cable connectors is utilized to allow 32 bit addressing to one or more RAM boards. This "32-Bit S-100 Overhead Bus" as I call it, allows the CPU to run at its maximum speed (no wait states) and with the current static RAM chips in pipeline mode. The current daughter RAM board utilizes 16MG of static RAM. The plan is to next add high capacity DRAM boards.... more »

compact XMODEM for CP/M
|
| |
This is my first post on this group - forgive me if this topic is old.
I couldn't find a decent XMODEM program for CP/M that would allow me to send and receive files to/from my various vintage machines via their serial ports - so I wrote one. (I usually assemble CP/M code in a 22NICE environment on a (virtual) PC, then send it to the target machine using Hyperterm, which supports the XMODEM protocol.)... more »

chip 733w01522 what is it?
|
| |
Is there anybody who knows what is this old chip? And where to try to find
it?
If it help what I know is that it used to do somenting like shift data
register or Serial Shift Registers.
It has a TTL level signal on its pins, it has 14 pins. You can see it named
U1 in the centre of this schematic:... more »

[link]
are there any versions of cpm adapted for networked 8 bit machines please?
when will cp/m be updated for z80 based machine stht have second processors like the fdd3000 - or the pds or the mciro command
or use networked machines please?
sam coupe has ˝mb internal but external 1-4mb code paged in above 32,768 runs closer to 6mhz80b speed... more »

Hello everyone, I got a board Xerox 820-II without any other components and without disk
controller. After changing the video sync and created a composite video on video i have
the correct prompt. I made a keyboard interface to convert a PS2 keyboard in parallel with the
same schematic that works well with my Ferguson Bigboard I and the other... more »
