So I dug this old Percom Data AT-88 floppy drive unit out of the pile and it didn't work. But after cleaning the floppy sensor, lubing the rails, cleaning the head, and then 3D printing a broken plastic latch piece, the drive works great. This is a weird and very old single-sided, single-density floppy drive for the Atari 8-bit. I guess back in the day they just slapped things together and stuck them in a sheet metal container. I'm not sure what these are worth -- if anything. Anyone have any interest? Comes with original manual, a copy of OS/A (in bad shape, but does boot) and the OS/A manual. Oh yeah, an SIO cable is also included and the power cable is integrated. This thing does work now, but it probably needs continued care and maintenance to keep it running -- it is over 40 years old at this point. Send me a message if you have any interest. Thanks!

Bingo! It was a bad MC14051B in the 2nd socket (farthest from the PIA). When replaced, all keys work. Thanks for the help all!

Thanks all. I will double check all of those.

So I've got this 800 and some of the keys do not work. I've tested the keyboard on another 800 and all keys test good. I've tested another keyboard on this 800 and same problem -- the keyboard has been ruled out. I've swapped the CPU and ROM boards with a known good 800 and that doesn't change behavior. CPU and ROM boards ruled out. Swapped out memory board without luck. Memory ruled out. I've swapped the POKEY and nothing. POKEY ruled out. I've check for obvious broken solder joins on the keyboard pin header, and reflowed the pins without luck. Are there any other ICs (like logic chips) that are known to be troublesome on the 800? Most of the keys works, but BREAK and ENTER (and maybe a couple others) do not. Weird!

These keycaps look amazing! Any chance you'd do a set for the WASD VP3 61/62-key ISO keyboard(s)?

The CMOS battery can be easily sourced. I decided to not put a new one in because it is buried deep and you have to carefully disassemble the entire thing to change it again. So instead I removed it while I had the laptop apart (and it had started to leak) and did not replace it. As for the NiCad battery that makes it truly a laptop, I don't know if anyone makes a replacement unit. I've had a few of these and the NiCads are always dead. As for the speed, you might be able to use CpuSpd (https://www.vogons.org/viewtopic.php?t=74359) to slow down the Pentium for timing-sensitive games.

If you're in the Seattle area, you can bring it to a Seattle Retro Computing Society or Seattle Commodore Computer Club meeting and there will be people there that can help troubleshoot. Just google those two clubs to find out meeting schedules.

SOLD Up for sale is a Tandy CoCo3 computer case and keyboard ONLY (no mainboard or power board or cables or anything else). I have no idea if the keyboard works, but the plastics are not yellowed and look pretty nice. As I'm not really familiar with the CoCo line of computers, this appears be undamaged except for a slot cut on the bottom of the case which I do not see on stock photos of this CoCo3, so I'm guessing someone cut this in the case at some point. Anyway, maybe someone can use this? $40 + shipping? Please look at the photos for condition. No screws of any kind included. Thanks!
