Stuart Posted November 8, 2016 Share Posted November 8, 2016 To take your minds off the US elections, I've had an e-mail from someone in Oregon, US who has got some TM990 module/parts for sale. They appear to be brand new, unused, boxed, with manuals (boxes have just been opened to verify the contents). Together they'll form a nice little minimal system that will run the TI Power BASIC software, plus the TIBUG monitor software, plus other stuff. Components are: -- 4 slot card cage -- TM990/101 Processor module -- TM990/302 Software Development Module -- TM990/201 Memory Expansion Module (I need to double-check that there is one of these) -- Set of Power BASIC EPROMs The seller is after $150 for the lot, plus postage/packing costs (each component is around 2-4 lbs. with the manual). To get it working, you'll need to be able to hook up a power supply to the card cage power terminals. A small PC power supply will work fine but you'll need to be able to solder some solder tags onto the power supply cables and sort out a power switch. You'll need a serial cable to connect the Processor module to your PC/laptop/whatever running a serial terminal application. Although the components are brand new, it's all over 30 years old so no guarantees it will work (you might need to replace a RAM chip or two for example). Having said that, the manuals have full schematics and all the chips can still be obtained, and I'm happy to help out with any problems (and have duplicates of the EPROMs). I've got spares of the TM990 modules that I've designed that I'm happy to negotiate on separately - IDE interface module (connects a hard disk or compact flash, with a simple disk operating system), 64K battery-backed RAM module, VDP and sound module (designed to use a TMS9918 with composite video output, but also works with an F18A but you'll need to build a small adaptor to reposition the IC socket). Details of the TM990 modules can be found here: http://www.stuartconner.me.uk/tm990/tm990.htm Some pictures of the bits actually for sale: https://portland.craigslist.org/wsc/sop/5865835012.html (it's on Craigslist for $200, but I've arranged to buy a second processor module separately, so $150 for the rest). If you're interested, PM me an e-mail address that I can pass on to the seller. The two of you can then come to whatever arrangement you like (no comeback on me should anything go wrong!)

I should have placed a bet that you would be first, Jim! I'll add you to the e-mail thread in a minute using your ksarul e-mail address in your message. Let me know on here if nothing arrives. (And I think it's a woman - Alexis.) EDIT - saw the e-mail address in the message! Edited November 8, 2016 by Stuart Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted November 8, 2016 Share Posted November 8, 2016 No messages yet, but then, I don't know when you fired the message off, Stuart. You're right on this, as I've been looking to build a 990-series machine for a while now. Quote Link to comment Share on other sites More sharing options...

Stuart Posted November 8, 2016 Author Share Posted November 8, 2016 And just to clarify - this is TM990 stuff - the industrial modules - not TI990 - the office system. Understood? Quote Link to comment Share on other sites More sharing options...

ElectricLab Posted November 17, 2016 Share Posted November 17, 2016 Dang, I would have been thrilled to get this stuff - this seller was literally a few miles from me, had an ad on craigslist, but ignored all my emails. The CL ad has expired or been deleted, so I hope it went to a good home! Quote Link to comment Share on other sites More sharing options...
Stuart Posted November 17, 2016 Author Share Posted November 17, 2016 It's gone to Jim. The woman put it on Craigslist just after she contacted me. It was still on Craigslist for a while after the deal was done with Jim. Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted November 17, 2016 Share Posted November 17, 2016 It is supposed to show up here today or tomorrow. . . 1 Quote Link to comment Share on other sites More sharing options...
kl99 Posted November 17, 2016 Share Posted November 17, 2016 Congrats Jim, How about some unboxing videos on youtube Please take a lot of photos as well. I would like to give them a nice section on www.ti99.eu 2 Quote Link to comment Share on other sites More sharing options...

Stuart Posted November 25, 2016 Author Share Posted November 25, 2016 (edited) There's a TM990 processor card (which you can play with standalone) on eBay at the moment for a very reasonable starting bid of $49.95. No bids yet - I suspect it will go unsold unless someone on here nabs it. This card appears to be made by Varian and is a copy of the TI card. Varian was one of TI's big customers for these cards. It includes a clock chip - which I believe also cores and blends apples. The card appears to incorporate a couple of mods made to the TI card (a couple of tracks cut and a pair of wires added) to tweak the memory map to support the clock chip. http://www.ebay.com/itm/VARIAN-PREDISPOSITION-IMPLANT-IMPLANTER-PREDAP-CPU-E-15002170-TI-TMS9900JDL-CPU-/132009625601?hash=item1ebc630801:g:bQEAAOSwj85YMksU Edited November 25, 2016 by Stuart 1 Quote Link to comment Share on other sites More sharing options...

I am putting the finishing touches on my new lab and will start moving into it next weekend, after which I will be playing with this stuff on weekends and some evenings as family obligations allow. I'm sure I'll have questions for you. Step one is to get a socket for the edge connector. I'll break the signals out to a breadboard and will wire up a power supply that way so I don't have to solder any wires to the card itself. 2 Quote Link to comment Share on other sites More sharing options...

Stuart Posted December 3, 2016 Author Share Posted December 3, 2016 Some more TM990 modules on eBay for a good price: Another CPU module: http://www.ebay.co.uk/itm/132022103829?ul_noapp=true 32K Dynamic RAM module: http://www.ebay.co.uk/itm/142199109600?ul_noapp=true Industrial comms module using a TMS9980 and TMS9903: http://www.ebay.co.uk/itm/142199109600?ul_noapp=true The seller has lots of other TM990 modules listed, if Jim fancies assembling his own wafer fab in his basement, right under his wife's nose ...
