In Topic: TMS9900 chip with additional marking MP9514

If Google does not turn up something, good luck finding any "offline" info. Someone would have to have the old datasheet or something. I have to imagine sourcing one will be even harder. If the differences were known, it might be possible to modify a standard 9900 to work?

Another quick update. Another person (I'll let him identify himself if he wants) sent me his MSX1 system (a Toshiba HX-21 Pasopia IQ) to test the F18A! It looks very similar to the HX-10 inside, has stereo output (the HX-10 is only mono), and uses the 9928. The tests went without problems, especially since the 9928 is socketed and has lots of room around it. Here are some photos:

Quick Update:

Construction is coming along pretty well. I have produced about 30 boards so far, so about half way done with the pre-orders! Here are a few photos of the construction progress.

Cool, thanks for the link, I just listened to the segment. It was a little strange listening to people talk about something I made, and not being able to answer the questions was frustrating. ;-)

I think the final question one of them asked was "why was it named after the jet fighter?" Actually it was not, it just worked out that way. The "F" is for FPGA, the "18A" is from TMS9918A, i.e. the chip being replaced. I suppose the name might make it hard to find via Google, but it is too late to change in now.

Just wanted to bump this because I'm listening to the hosts of the Retro Computing Roundtable talk about this new chip. Looks very cool! Any updates?

Cool, do you have a link to the talk? Obviously I'm very interested in anyone talking about the F18A. I know it has been a while since I updated the F18A thread, but I've been spending my spare time building boards and writing test programs. I have some new pictures and hope to get a public update soon. Apparently harlock76 is a pre-order customer (I don't know most of the people who pre-ordered, and I have no idea who they might be in any of the forums), but I am trying to keep those who paid somewhat up to date via email.

I finally got my reflow oven working and I have built about 30 boards as of today (I made 20 in the last two days). So, the pre-order hardware should be done soon, and I then just need to finish the testing, write the install docs, and get them shipped.

If anyone has any questions, please don't hesitate to ask. I'm mostly active in the 99/4A sub-forum, but I lurk here and a few other places as well.
