We're getting a CompuPro

01 Jun '16

There is a nice donation arriving in a couple of weeks. As described by the owner: "Godbout CompuPro S-100 bus CP/M-80 microcomputer with dual 8" floppy disc drives, quite a few discs with software, some docs, a Hazeltine Esprit CRT/keyboard terminal, and Xerox Diablo daisy-wheel printer" This is a historic system and I remember Herb showed one a few VCF Easts ago.

TEI MCS-CPU 8080 CPU Board
by Systems Glitch 01 Jun '16

01 Jun '16

I picked up a TEI MCS-CPU from Jeff Galinat at VCF East XI this year. It's an 8080 CPU board with onboard power-on jump, power-on reset, and MWRITE generation. Jeff didn't have any documentation on it, and I've been unable to find any online, other than mentions in sales literature. I took a little time tonight to go through it, figure out the onboard functions, and get it fully operational: http://www.glitchwrks.com/2016/05/31/tei-8080-cpu Neat little board, though TEI expected you to use the extra features (power-on jump, power-on reset, and MWRITE) in an all-or-nothing fashion: jumper J1 enables or disables everything. I wanted power-on jump and power-on reset, but didn't need MWRITE since I was using a front panel with it, so the writeup includes the trace cut modification I used to disable it. There are convenient vias on either side of the cut, so you can add in socket pins for a removable jumper. The writeup also documents the function of the switches for setting the power-on jump address. As I was working on this board, I noticed that the layout of the basic CPU function (excluding the add-ons) is *very* similar to the IMSAI MPU-A. Can anyone comment on this? Thanks, Jonathan

I need rid of it this week and I don’t want to toss it. Please come and rescue it. Greg Acker Merce, PA

Remember this online Spectrum article from VCF East last month? http://spectrum.ieee.org/tech-talk/geek-life/history/theyre-alive-vintage-c… I'm told it is in the current print edition, too. Cool!

WTB: MOS6560 / VIC Chip or Parts VIC-20
by Todd George 31 May '16

31 May '16

Need a MOS6560 to replace a defective one in a VIC-20. Additionally would consider a parts/ugly VIC-20 with a 6560 that has a fighting chance of working. I can desolder and all that. I've seen the dealer on eBay and am choosing to spend my money elsewhere (in the community). Hit me up off-list if you can help. :-) -Todd
