Hi AJ (and list), I got that one. Todd On 1/13/2018 10:02 PM, AJ Palmgren via cctalk wrote:

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.

It's interesting, I had exactly the same machine a long time ago, but with a different label.

You're right, the machine I owned is the one I see from your link. The workstation you mentioned is in the same box but with a monitor and the location of the clips and led slightly different. But I was not far ;-) I don't remember what kind of hardware was exactly in this machine. Shame on me, I got rid of it, it was the pre-internet era, I had no hope to repair and reinstall this machine, it would be different today: - / On 17/01/2018 20:02, Alan Perry via cctech wrote:

from my Convergent MightyFrame-email address to you directly, and let's see

Hi AJ, Thank you, I've been looking for 3b1s and 3b2s for a while. I plan to eventually be able to image the disks and scan the documentation. It will however take a while to get to that point. I'm open to loaning media and manuals to someone who can get that done quicker (I'm in southern NH.) I'm also happy to open up the machine and do what I can to help identify differences though I don't have a "regular" 3b1 to compare against myself (I'd love one and any 3b2s I could get my hands on as well.) You or anyone else should please feel free to stay in contact with me either on list or off. Thank you!
