Years ago, we used one of the Convergent machines. I recall playing rats on it. It had a green screen. It was a 8086 processor and had some Multibus slots in it.
I recall the SA8000 hard disk. It would fail after 20 minutes or so. We sent is back to Shugart for warranty repair with a complete description of how it needed to run for some time before it failed. They sent it back still broken. I when to Shugart with the drive and found out that they never even looked at the return sheet they had me fill out. They just replaced the drive belt tested it for 2 minutes and sent it back. I couldn't wait for them to not fix it again. I bought a replacement transistor for the stepper drive and fixed it my self. We used them because of the bus slots on the back. I made a DC servo controller to run an XY table. I had an early version of fig Forth running on it to debug my hardware.

Unix PC, AT&T 3B1 Unix Workstation Todd, thanks so much for sharing, and I'm thrilled to know that a member of this community is where it's going. May I ask, what are your plans for archival of the included disks and manuals, if any? I'd also be quite curious to see if there are any internal circuit differences between that machine and a "regular AT&T 3b1. If you ever open it up, I'd love to see/hear about that. I've put a fair amount of effort into preserving Convergent-branded OS and programs, particularly from this era, solely out of personal interest. Mostly for the MightyFrame, but my journey had to start with the AT&T UNIX PC first, as that had the larger "still available" user group for learning & support before I could revers-engineer how to get a MightyFrame to boot. Anyway, I would really love to see those software/manual sets be preserved in a bitsavers.org / archive.org fashion, and if there is anything that I might be able to do to assist in that effort, I'd love to volunteer. My site for preserving this area of Convergent software and equipment is at http://MightyFrame.com Please let me know how I might help, in any way. Thanks so much! -AJ On Sun, Jan 14, 2018 at 8:26 AM, Todd Goodman <t...@bonedaddy.net> wrote: > Hi AJ (and list), > > I got that one. > > Todd > > > On 1/13/2018 10:02 PM, AJ Palmgren via cctalk wrote: > >> I'm just wondering if anybody here did (or knows who) bought this one. >> >> http://ebay.to/2DaRr13 >> >> Even though these were all manufactured by Convergent Technologies, this >> one is actually BRANDED by Convergent, as their model S/50. >> >> And there's software included here.
