I finally got around to the P-GRAM/P-GRAM+, as I needed it for an upcoming project. It came out looking good,too as I was able to get the entire thing onto a single page. A3-P-GRAM-P1.pdf 413.68 kB · 14 downloads One note on this one: I realized after I posted it that I had CR2 facing the wrong way. I'll be updating it to make the correction sometime this week. 2 Quote Link to comment Share on other sites More sharing options...

I'll get all of them scanned/restored soon, as some of these are in pretty bad shape. I know this is an old thread but if possible I would like to have a copy of Corcomp RS-232 PEB card. Thanks OK I just found it all on another post. Thanks Edited April 27, 2022 by johnph3 Quote Link to comment Share on other sites More sharing options...

johnph3 Posted April 27, 2022 Share Posted April 27, 2022 Thanks I have the original manual, not sure it's the right one for my card. They may all be the same. How ever in trying to figure out why my pdm cartridge doesn't work I removed my TI RS 232 and put the CorComp RS 232 and ran the same test. Well the corcomp PDM still doesn't work However the disk program that runs RS232 tests. Reports back that I have a bad rom in my Corcomp RS 232 card. That is on the test for RS232 1 out to 2 in. The standard loop test works just fine. Confused! BTW I found a schematic in another post. The schematic is not in the manual. Quote Link to comment Share on other sites More sharing options...

A long-time TI user in the Netherlands obtained a set of CorComp schematics from the European distributor for CorComp products sometime in the late 1980s or early 1990s. The schematics were sold by his son on eBay as part of a folder full of random schematics after he passed away. I bought the lot and found the somewhat large group of previously unknown CorComp schematics in the folder along with quite a few known schematics from TI and other sources. I scanned the CorComp stuff and put it online to ensure its preservation. On the manuals for the various CorComp cards, the contents applied to all variants of any given card. 4 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted July 25, 2022 Share Posted July 25, 2022 Here's another useful schematic set for Geneve users: the MEMEX board. I will soon make a few test boards using the layout I made to verify it and return the board to general availability if everything works.

+mizapf Posted July 25, 2022 Share Posted July 25, 2022 "Zero Wait Off" made me have a second look. ? It's not ambiguous, but I had to do one more mental iteration. Quote Link to comment Share on other sites More sharing options...

How is the LED driven in that arrangement (CRU bit, address space selection, or _CS?) Also, I believe the 8580 and 6581 should use different filter capacitor values. (Ah, this is documenting the design, not a new design. Nevermind.) 2 Quote Link to comment Share on other sites More sharing options...
