I am happy to see that this project has continued! My TI-99 itch has come back, and I think I may try my hand at reworking this to fit inside of the original console.

Unfortunately that was my very last run of boards, and they have all been sold a while back now. There is a seller on eBay who is periodically making them, but looks like they are currently sold out. You may want to reach out to them to see when their next batch will be...

I am "getting out" of the Tandy EX/HX game, and I am doing one very last run of my Tandy 1000 EX/HX 3-in-1 Upgrade Board. These boards are an all-in-one upgrade solution for people who just want to play XT/Tandy era games, and it provides the following upgrades: 640kb System RAM 96kb of Upper...

This really came out of left field today, but there is an old General Instruments ANIC-A for sale on eBay right now that seems to have some documentation... It is very expensive, but you might be able to haggle with them. https://www.ebay.com/itm/165376540588 Unfortunately, I cannot help much...

Ah! You have it working! Did you happen to make a note of the error(s) in the schematics I published? Ive been meaning to get back to troubleshooting, but free time seems to be a very fleeting resource for me lately.

I apparently never replied back here, but my adapter is now complete and I have been selling them on eBay for a little while now. I just made another batch of them, this time with shorter cables, and they are working out great!

I do have a solution, I am just working on the spit and polish before it is ready for sale here.

The new version has arrived, and is a good amount smaller than my first. I whipped one together and it works well. I just need to find a source of DIN7 cables that have consistent wire colors, as each and every cable I have has a different pattern. I also need to pick up some heat shrink...

So, I have not yet "given up" on this reproduction, but it is currently on the back burner at the moment... In the meantime, it looks like Scott Baker published a design for some PS2 to Tandy adapters late last month. I laid out a variant of it which is quite a bit smaller and is designed to...

The boards arrived, and I quickly slapped one together (with the sockets that I have.. I ran out of 24 pin wide sockets).. only to find that I never ordered the transistors. I ordered them the other day and they should be here shortly.. but significant progress has been made.

I am on a side mission to recreate the Tandy 25-1030 Enhanced Keyboard Adapter for the Tandy 1000/A/HD/SX/TX computers. I borrowed such an adapter, stripped it down, scanned it, and duplicated the layout in Sprint Layout yesterday. I am just putting the final touches on it now, and I will...

The first draft boards have arrived. My 1000A and the logic chips needed to build this board will arrive tomorrow, so I will have initial testing done sometime tomorrow afternoon.

My first pass is complete. I sent it off to be fabricated for my initial tests.

I am announcing that my Tandy 1000 EX/HX 3-in-1 Upgrade Board as complete, and I am currently assembling boards for my production run. These boards are an all-in-one upgrade solution for people who just want to play XT/Tandy era games, and it provides the following upgrades: 640kb System RAM...

The connectors arrived yesterday, and while I have not inspected every single one.. they seem to be perfect. They have a snug fit right out of the package, which I am very pleased with. The company I used is called Shenzhen RealRun Electronic Co. They typically have a MOQ of 1000, so I did...

I do not have a photo of my HX set up, but I do have this one of my TL2 and a Panasonic branded version of the 3000NL.

I too finalized my design. My final prototype arrived today, and I quickly assembled one. I had to tweak the placement of one part and fix some of the silkscreen, but all in all it functions perfectly. I purposely did not flush mount the passives to help in disassembly if the need arose, so...

My first prototype of my 3-in-1 board arrived yesterday, and I quickly assembled one. It turns out that the footprint for my CF card slot was completely wrong for the part, so I did not assemble the XT-IDE portion of the board. I also apparently put the PLUS connector 2mm too far to the...

I am seeking a Panasonic Business Partner FX-1650 computer. I would accept a 1750 if I cant find anything else, but I greatly prefer the 1650. I do understand that the Tandy 1000SL2 is essentially the same thing, but I am purely interested in the Panasonic. I do not care if it has a keyboard...

It is nothing more than a XT-CF-Lite board adapted to fit into the PLUS slot. Memory was next on my "to-do" list, and I am open to trying to combine the designs to one board.
