I’d be interested myself, but unfortunately I just lack the space. 5 Quote Link to comment Share on other sites More sharing options...
+FarmerPotato Posted December 20, 2022 Share Posted December 20, 2022 I bought the CPU... WOW. The seller's web page: http://www.rknorman.co.uk/DART and TI990 Documents.html * also the COBOL accelerator... no idea what for. 3 Quote Link to comment Share on other sites More sharing options...
+FarmerPotato Posted January 3 Share Posted January 3 Supposing I were building a little backplane to plug the 990/10A cpu into ... I looked for the necessary 80 pin card edge connectors. No keying. No weird pitches, just 0.1". Mouser, Digi-Key, Farnell/Newark, electronics surplus, goldmine, Arrow, Jameco, PEconnectors, ..? Kinda obscure and pricey. Want to order from North America. So far, Arrow had the best price at $5. ?? Newark has some on clearance for $7.72. Direct from TE connectors site: the 2-5530843-0 is $6.31 Mouser 6.32 on qty 10 Others have them at $10-$15. Some are surface mount types, which could be ok, but they're pricy. Any other leads on 80 position, 40x2, 0.1", solder tail (or wire wrap) card edge connectors?

+retroclouds Posted January 16 Author Share Posted January 16 Anyone knows what that is? https://www.ebay.com/itm/255035224868?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=SgkaoV_QQka&sssrc=2349624&ssuid=EJfVC6FkS6K&var=&widget_ver=artemis&media=COPY 4 Quote Link to comment Share on other sites More sharing options...
+FarmerPotato Posted January 16 Share Posted January 16 WOW! The AMPL system was a developer tool for 9900 hardware systems (call that a device-under-test, DUT.) It looks like a 9900 inside the "buffer". One cable would connect this module into the DUT's CPU socket. The other cables (2?) would go to a card in a 990/4 minicomputer. Not sure about the internal 9900's role. The AMPL software could do such things as single-step, or record and show instruction trace.

jbdigriz Posted January 23 Share Posted January 23 (edited) Other targets were available, too, iirc, like TMS7000. AMPL preceeded the XDS standalone and PC in-circuit emulators that do not require a 990. Looks like a fried wire in the target cable; hope the buffer board isn't dead.

Any other leads on 80 position, 40x2, 0.1", solder tail (or wire wrap) card edge connectors? Sorry, only just seen this. The connectors aren't 0.1" pitch, they are 0.125" pitch. I got some from a surplus place recommended on there somewhere. I will find it and put here. Edit: Oh, it was you that pointed me at the company. https://www.electronicsurplus.com/gc-electronics-41-858-connector-pcb-edge-40-position-80-pin-dual-a7d40ww27a3 Edited January 25 by Jimhearne 2 Quote Link to comment Share on other sites More sharing options...
