I can probably help you get CP/M up and running on your computer no matter what it is. All we'll really need to do is configure serial I/O to match whatever hardware you end up having. The diskettes posted by modem7 look perfect for the Micropolis drives.

Hi Mike,
I am assuming your last post was aimed at me
A quick note about my background as I believe it is relevant. I started in IT in 1977 working on Data General and DEC Mini computers, doing maintenance and chip level repairs. I have also built and programmed most 8 bit computers, like the SC/MP, S2650, 6502, 6800, 8080/85, Z80 etc. I have repaired and maintained CP/M and MP/M systems. I also learnt to program in assembler, C, C++, Fortran, Cobol, Pascal, Basic and Algol. I have 3 IT related Diplomas and have qualifications in Netware, Unix and Microsoft products, not to mention 30+ years experience in hardware and software support. I am currently the IT Manager at Haigh's Chocolates.
As a hobby I collect and restore vintage computers, I have 60+ Macintosh machines, every apple 2 from the plus through the GS, and 2c. I am in the process of building 2 x Apple 1 computers using period correct components. I also have a few curiosities like my Triumph/Adler Alphatronic CP/M machine, Sun Sparc 5i and my S100 system.
The RASE80 CPU board looks like the ideal candidate, as it has 2 serial ports, Parallel, ROM, RAM, RTC and the 4Mhz Z80. I have managed to get it communicating with a serial terminal and can access the inbuilt 2K Monitor program. However I have no documentation for this board or the RASEFDC boards. (I sent out 2 emails in a desperate attempt to locate information, but I do not have very high hopes). I was going to use the floppy drives from the TA Alphatronic system as they are 360K soft sectored drives.
Given the RASE80 board is not going to be usable without a lot of reverse engineering of the Monitor and hardware, that leaves me with the Cromemco ZPU board, 3 ram board one of which uses 6116 static ram and/or 2716 Eproms (I am thinking of a monitor ROM to facilitate debugging of the CP/M system). The Micropolis drives have the companion Micropolis FDC board, which seems to have a 256/512 byte bootstrap ROM.
The only thing I need is additional serial IO to be able to start communicating with CP/M. My biggest issue is being able to write a basic CP/M system to hard sectored floppy disks. I seem to have picked a esoteric variant, but that's part of the attraction. I have now sourced 3 boxes of hard sectored diskettes and should be ready to start work once I locate/source a serial IO board.
Finances are a little tight but I envisage being able to start work within a few months, my aim is to have a basic CP/M 2.2 system up and running before christmas.
I would appreciate any comments, suggestions or feedback on this project.
Thanks and Cheers, Martin...
