The 5200 and 3200 can use normal power cords, but the 1200 needs a power supply that outputs something like 15 volts

Feel free to make an offer! From how much it sells for on eBay I have a vague idea of how much it might be worth, but I couldn't find any sold copies of the IBM version, not to mention a sealed copy, so I'm definitely willing to try and make a deal with someone on it. I also have an unsealed but...

This looks to be a clone of the IBM card, and is in excellent condition. It would be great for a restoration or repair of an old Eagle computer. Asking $100 for it. From a historic standpoint, this card was made on the 22nd week of 1983, mere days before Eagle's CEO and a passenger flew through...

I found one of these lying around the store, but it's not booting. The orange light comes on, but nothing else happens. Where should I start? Thanks!

This may actually be an unused processor, but I'm not sure. The box is in bad shape but the antistatic box the CPU sits in is in great shape (except for the color, maybe, I'm not sure on that). The box is missing the manuals and diskettes, but they're not super important unless you're a...

I can't find any listings for it on eBay, so I figured I'd put it here a couple of days before I put it on eBay for an absurd price (I don't have anything to go by so I'm probably just gonna start high and lower it as time passes). Feel free to send me an offer for it if you're interested...

There are broken plastics, rocks in it (i don't know how either, don't ask lol), and it is untested in every way. The plastic translucent cover is missing. The rest is intact. It is free to anyone who is willing to drive to EPO Houston, zip code 77063. If you're coming to get it, please reply to...

I know the external power supply is good, and I know the RF modulator is in good shape. The unit was in bad shape, so I wouldn't be shocked if there's multiple faults here... I don't know much about fixing the TI 99, so I was wondering if someone could help me diagnose it. Thanks!!

I have 5 of these, looking to sell for about $25 each. None have boxes, but they're stored in old anti-static bags and don't look to have any use. They have Ethernet and a 15 pin connector (AUI?). PM me if you're interested, thanks!

This monitor is in such good shape there's some debate where I work as to whether or not it's ever actually been used. Monitor is untested, since I don't have any CGA computers on hand. The manual and other documents are still sealed. Local pickup from ZIP code 77063. Looking to get around $200...

This was released back in 1987 or 1988 as a tool for professional repair shops to quickly test if 64 K or 256 K RAM chips were good. The unit was later expanded with a 1 Meg Module, capable of testing 1M x 1 DRAM, and 64 or 256 K x 4 DRAM. I used it on my own old stock and found a couple of bad...

I've recently gotten a bunch of late 1960s to mid 1980s boards, most of which look to be at least vaguely computer related (and broken but that's beside the point lol), and I was curious if anyone knew anything about them. I have some guesses on some, but others I'm completely clueless on. If...

Panasonic seems to have made at least a short run of them at one point. They're called LT-1 floppies. I don't have any, but I'll keep an eye out for some. :)
