Hi everyone, new member here, and my second time around collecting Tandys. In 2023 I had a 1000 HX, 1000 RL, 1000 RL-HD, 1000 SX, 1400 LT, and 2500 SX. Ended up selling them off in 2024.

In 2025... got the bug again. I now have a 1000 RLX waiting on an XT-CF upgrade; 1000 TL/2 that came with a Make-It-486 and Wonder EGA, and I added an XT-CF and 2 MB EMS RAM; 1400 LT with an added XT-CF (also the original 1989 receipt and carry case!); a 2500 XL that needs a 3.5" disk drive (think I have a working spare) and doesn't do else much yet; a 2800 HD that I just got to fire up with a new AC/DC adapter but is stuck at the HD init in POST; a 4000 SX that isn't doing much but beeping POST yet; a 4016 SX that I had working perfectly until I added a CD drive and broke a motherboard capacitor (C12) with a ribbon cable; and a Sensation I that I'm really happy with my work on.

Accessories include a DMP-442, CM-11, MMS-10 speaker system, and VGM-390. For something different, I also have a DEC LPx 433DX that sees its HD but won't boot from it. I'll take a pic someday when most of these aren't in pieces!

So, a note on the 1000 TL/2 in case this saves someone some trouble -- in upgrading to a Lo-Tech XT-CF I went through probably 15 configurations trying to make the Wonder, XT-CF, and 300 baud modem card all work together. I ended up using the offset BIOS file for the XT-CF with the jumpers out of the box at C800/300h, a Lo-Tech 2 MB EMS card set to D000 and its out of box IO address.

So the one I'm happy with my work on, the Sensation I... it arrived DOA. Pulled the PS and found damaged caps, of course, but lucked out that they print the voltages and pin numbers on the board! Looked over at my spare ATX PSU, measured the voltages, popped the pins and they fit into the Sensation PSU to motherboard connector... it's alive again!!! Yesterday I installed a pico PSU and AT adapter and it made the video output look new! Then on top of that, popped my IDE SD ISA card out of my hopefully not dead 4016 and the Sensation booted Windows 3.1 right up! I also managed to find a Tandy CDR-3100 external drive which is really just a standalone power supply and case for a LMSI CM-205... took it out and put it in the Sensation with a 16-pin IDC cable from Amazon, found the original Tandy CD ISOs and found the driver and config.sys line, and MSCDEX and the autoexec.bat line, and it detected!

So next for the Sensation, I'm partitioning a SD card to load the CD ISO files and install the original Tandy system! The amusing part... I'm doing all this DOS reading and writing on a Mac.
