In 1974 I had a 370 and then in 1982 when I worked on CP/M systems I got myself a Micro-professor. I left it in the office when I went on annual leave and it got stolen: I'm still pissed off about that, 30 years later.

Nick, I wrote a paper-tape Motorola format loader for that very evaluation board in my second year as well as a model train controller, and one of my final year projects was a message switching network of four of them.

Oh, cool. You were lucky to have four of them!

Here is another RAM board I had to solder together myself:



And this is the UVEPROM that held the assembler that I had to write in hex machine code:

When Intel released the 8085 in 1977, there were some accompanying support chips like the 8155 (RAM with IO ports) and 8755 that made possible a very compact (~3 chips, 40pins each) single board computer (and there was a reference design for this in the databook.)  Unfortunately, none of those chips was inexpensive or easy to obtain; I don't think that board particularly "caught on."

Oooh!  I recognised that format!  Motorola Exorciser.

1980s - Digital Systems Lab UNSW - three boards fabricated; CPU (sparsely populated; 6809), BBRAM up to 64K, floppy controller.  "G CD03"

Did a complete re-write of FLEX09 from disassembly, as well as porting a BASIC09 to true 6809 and enhancing the code for the 6809 "Serge" VDU.  If I could get the CPU board working again it just might be possible to recover the data from the (720K) floppies.  Sad.

I really wish I had not "loaned" my 1978, 768 byte SC/MP home-grown 5" cubic micro with the hex keyboard and displays but no ROM, to some fellow hoping to get him interested in such things.  I don't think he was, and it got lost.
