Hi folks, I'm looking for a Tandon PCX-20. If anyone has one that they're looking to find a new home, ping me the details. I'm in CA (SF Bay Area), open to shipping from wherever you may be.

Thanks!
 
I have this set of cards Tandon for sell

I was unaware that Tandon made desktop PCs. Let me know what you find!

Yep. My PC AT Clone is a Tandon TM7100. It's not a bad computer, but the documentation for it seems scant, at least when I was last messing around with it. I have 4 MB of memory (1 on board, three on an expansion card) and have DOS and Xenix 286 installed on it.
 
The PCX-20 was my the first machine I owned after the 8 bit era. I was a young teen at the time, managed to buy it second hand. When I bought it, it came with a 286, 1MB RAM, 20MB MFM hard drive, a 5 1/4" floppy and a Hercules video card. It came with a Tandon keyboard, but I think the amber monochrome screen was from another brand.

In the scheme of things, spec-wise it wasn't much, but definitely learned a lot back then from it. Would love to add one to my collection. I ended up selling it to help pay for the first machine I put together from scratch, which was a 386DX.

Do you happen to know what the differences are between the PCX-20 and the TM7100? I looked up the TM7100 and it looks similar, but can't find the specs.
 
So, I speak French like a Spanish cow, but based off of this image I found from a French ad, it looks like the PCX is a PC XT clone, and the PCA is a PC AT clone. The case for the PCX looks slightly shorter, with two-by-two 5.25" bays, while the PCA has three 5.25" bays stacked. Honestly, I'd never *heard* of the Tandon TM 7100 until I came across this AT clone which a friend of mine had picked up at a thrift store in Boulder, CO. I think they may have sold more machines in Europe than they did over here, where (at least in my memory) they were predominantly a supplier of floppy drives. My AT has a sticker on the back of it that says it's model number TM 7100, but it looks exactly like the Tandon PCA 20 in this ad. I found another site that references the PCX 20 as the TM 6004A, so maybe they have that 'TM' model number that the guys in the warehouse used and the 'PCA' number that the marketing guys used? :)

Thanks! I wonder if I had a Frankenstein machine. It was definitely a 286, but it had the form factor of the PCX. It had a 20MB MFM drive in the right hand bay, and floppies in the left.
 
Here's a picture of my Tandon AT clone. You can see that it looks pretty much exactly like the computer in the ad I posted earlier, aside from the addition of the 3.5" floppy.

Depending on when you bought it, and assuming you bought it new, it's possible that whatever shop you got it from picked up a bunch of PCX computers (or had a bunch of unsold stock) that they just replaced the board on in order to make them a bit more 'sellable'. Or it's also possible that Tandon themselves decided to get rid of some extra PCX cases by just sticking 286 boards in them, just like IBM did with the Model 5162 "Model XT 286" systems. Do you remember if it came with a 360k or 1.2M drive?
 
Turns out it was a Tandon TM 7002. One just appeared on fleabay in the UK for a staggering amount of $.
