The Logic Test tab can help you do it. It is tedious but you can put in test inputs (including a clock) and assertions about the outputs. I wrote 24 test vectors for my last 22V10C with 10 bits of storage. it exercises setting/clearing each of the 7 bits I need. So you just have to work on the test input sequence for your PAL/GAL. I’m still not sure if the clock is a down pulse or up pulse (guess I need the scope). my test vectors worked on the 866II but the clock again is all wrong on the T56. It’s also unfortunate that the test vectors have to be put in through the horrid GUI. the save format is some binary, where a simple text file would be so much faster to edit.

atrax27407 Posted November 17, 2021 Author Share Posted November 17, 2021 (edited) From time to time, someone posts a message lamenting the fact that there are few eprommers that support the old 25V chips that some of our TI gear uses. Most of the ancient chips were replaced by 21V versions in the early 1980's. Those, in turn have been replaced by the more recent 12.5V (or "A") versions. There are even 21V versions of the 2716. In a pinch, you can use a 2732 (same pin config) to replace them and simply program the first 2K. It seems that there are almost always "work-arounds" for most problems. The TL866CS/A will do 21V chips - the TL866II will not since it is limited to 18V max. The new T56 will do 25V chips. The only nominal 25V chip in the mix is the TMS2532 (the "A" version is nominally a 21V chip) and even it can be programmed easily. TI - either by choice or chance - apparently used a single die to manufacture the TMS2532 and the TMS2532A. By extension, the Motorola MCM2532C, and the Hitachi (and other clones) which were licensed by TI and also used the same die are programmable at 21V. Some years ago, Tony Knerr discovered that both could be successfully programmed on the TL866CS at 21V using a simple adapter. The fact is, I have been able to program literally hundreds of them without fail using Tony's adapter and programming them as a TMS2732A. I have found that, much to my delight, my TL866CS will do just about everything that I need it to do.

atrax27407 Posted November 22, 2021 Author Share Posted November 22, 2021 Got an interesting chip in the mail this morning - a MOTOROLA MCM67864C. A cross-reference shows it to be the equivalent of the virtually extinct 24 pin package of the TMS2564. Now, to sit down with the data sheets and come up with an adapter for it. 2 Quote Link to comment Share on other sites More sharing options...

+dhe Posted December 30, 2021 Share Posted December 30, 2021 I have a question about the T56... I'm guessing a typical USB can't supply the power to burn 25V EPROM's, but the T56 can, because it has provisions for adding a transformer? I asked one of the vendors on ebay, if they could point me to a transformer that would work, and I got back specs. Is anyone using a T56? Do you need the transformer to burn 25V devices? If you do, what's a good part number for the transformer? Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted December 31, 2021 Share Posted December 31, 2021 I've got a T56, but I haven't had to burn any 25V chips yet, so I haven't gone hunting. Quote Link to comment Share on other sites More sharing options...
atrax27407 Posted December 31, 2021 Author Share Posted December 31, 2021 Specifically which 25V chips are you trying to burn? The TL866CS will burn TMS2532s with an adapter. They appear to program at either 21V or 25V (along with the TI-authorized Motorola and Hitachi chips) as mentioned earlier in this thread. Most of the older 25V EPROMs have newer 21V versions. 1 Quote Link to comment Share on other sites More sharing options...
+dhe Posted December 31, 2021 Share Posted December 31, 2021 Hi Atrax, I don't have a particular chip in mind, but figured having the transformer wouldn't be a bad idea, and just keep the extra juice plugged in? Quote Link to comment Share on other sites More sharing options...

speccery Posted March 26, 2022 Share Posted March 26, 2022 Thanks for this thread. I bought a while back the TL866II-Plus programmer thanks to this thread. It has been waiting in its box, but today I used it to program a new ROM for the Stephen Cousins' SC130 single board computer. Worked great on my Windows box. I used to hassle with a Windows 7 VM running under parallels on macOS as my previous programmer did not support Win 10, I haven't bothered trying to get virtualisation running on my MacBook Pro running Apple Silicon. 1 Quote Link to comment Share on other sites More sharing options...

atrax27407 Posted June 15, 2022 Author Share Posted June 15, 2022 (edited) It looks like they are going to take the TL866II out of production and replace it with the T48 in the near future. Jim Fetzner speculates that they found that the TL866II has been cloned. Edited June 16, 2022 by atrax27407 Quote Link to comment Share on other sites More sharing options...
