I'm the one who made the thread about the 430NX. I've got 4 boards now that all exhibit the exact same fault, and refuse to work properly with NOS/Glitch Replacement 12887s, but will "work" with their original Dallas chips (just not save any information, and have garbled data for time/date) -...

Looks to be a Tandy 2000. I've been working on one lately. I'd take a picture of it, but it requires a lot of disassembly :) The RAM modules and front-facing keyboard connector give it away. It's an interesting machine. 80186 CPU. MS-DOS compatible, but not 100% IBM Compatible. Uses 720k...

I know the guy who won, they're going to a very good home to be restored, and might even show up at a VCF Exhibit someday :)

I'm still looking for anyone who might have a 430nx with an intact RTC battery :D

It was their shot at a 486 machine. The early ones were actually made by Tandy, but then they dropped it and had AST build them. I've been looking for one (either Tandy or AST built model) for a little while now, without luck. They weren't rare when new, but they sure seem to be now. Seems...

That is one hell of a machine. I would love to add that to my collection of obscure machines, but I'm pretty much out of play money for the next few months and even the shipping (or trip to pick it up) is beyond my means currently. I hope it finds a good home, it definitely deserves one.

Nice. Going in half with a friend. 500 seems more than I'd ever need.. but 250? Yeah we can do that.

The Model 4 had RS-232 built in to my knowledge. Was your daughterboard damaged or missing? The port should be on the bottom, next to the expansion port.

I'm looking for a Tandy Sensation. 386 or 486 is ok, I'd prefer a real Tandy / pre-AST model, but beggars cannot be choosers, and I'll consider the later AST-made ones as well. I'm not trying to break the bank, but I realize these are pretty rare these days for some reason. They didn't seem...

There is a pair of disks labeled "Basic networking" included. I never tried to get it going One person left a review on the archive stating "I was able to install Venix/386 into mame with the at386 machine and also the PCem emulator." No idea on Virtualbox.

Yeah, the M3SE with autoboot ROM would get you up and going if you want to spend the money. Cheaper option is a Gotek with HxC or FlashFloppy like Larry said above. My machine has a HxC based gotek with a custom front panel I built, and I really don't feel I need more expansion or...

My model 4 was the exact same way. I assumed something was wrong with the floppy controller. The :1 position would not work with any drive I installed (and I tried several compatible drives) I installed a HxC modded Gotek in the lower :0 position and haven't thought about it since.

I have a repair job on a Tandy 3000 that had the battery explode and it's bad. Several components in that corner of the board have lost their markings (or just departed the board). I'm hoping someone has an original Tandy 3000 (Not the NL or HL) that would be willing to open their case and...

I found a complete functional copy of Venix/386 - and have successfully imaged the disks and uploaded to the archive. I could not find any other archives of this Unix anywhere, so I might have brought this one back from the dead! I have also managed to install it and get a functional system on...

Today, I encountered my second 430nx based board, and it had the exact same issue as the 1st board I had tried to get going about two years ago. Basically, it seems when the Dallas RTC's die on these boards, replacement does not work. The first board was a Packard Bell LPX board, after...

Yes, I've been to that page, which includes the "pinout" for wire colors for the plasma connector, but not what voltages / signals might be present.

When you remove the backplate, the wire goes to the right hand side,and runs down. It has a piece of heatshrink over the connector, zip tied in place. When disconnected, the plug looks like the attachment. I also understand there were two different PSU's used on the P70, so if you don't have...

Does anyone have a P70 that would be willing to disconnect the plasma power connector (6 pin) and take voltage readings? You have to cut a few zip ties and slide some heatshrink out of the way. I can't find a reference anywhere for the plasma voltages. I have a "pinout" with colors listed...

I just got a Poqet today. Slapped in batteries, got a high pitched whine out of it. Pressed Reset. One line. Went HAM on Reset, wiggled, moved, pushed, wobbled, really gave it the beans... Once I let go, the machine booted. LCD has a few 'dead' lines at random spots from top to bottom...

Does anyone know what system these boards go to? 1700381 Rev D Tandy PN 870-9838
