PM sent. I have Coleco & Sears Pong units available for sale or swaps.

As per the title, I'm looking for an +original+ MITS main board for the Altair 8800. MITS called this the "expander" or "expansion" board, but it's what we'd all call a motherboard or even a backplane. If it's an original, it will have 2 or 4 slot connectors. It does need to be cosmetically &...

As per the title, I'm looking for an +original+ MITS 1K or 4K SRAM board for the Altair 8800. It's OK if it's not in working condition, or just "unknown" - but it does need to be cosmetically decent and an original MITS part. Thank you, please let me know what you've got. I know I'm a new user...

Wiki puts it this way: "IEEE-488 specifies a 24-pin Amphenol-designed micro ribbon connector." - which is correct, but.. It's probably important to reiterate that there is no compelling technical reason (other than outward compatibility - not always desirable) that a given implementation needs...

IEEE-488 is an evolved / adopted standard that was originally created to define communications between automated test & measurement equipment. The standard has since been supported (in some non-standard ways) on many hardware systems over the decades. One well-known instance is the Commodore...

Wiki suggests this might be an "E-LINK Serial to IEEE Interface" The chip complement matches the description - 65C02, 6522 and a 4K ROM (well, EPROM of unknown size - I don't want to peel the sticker). Interestingly, it's built on an uncommon type of factory-CBM VIC-20 cartridge case. If you...

I'd be open to offers of C-64 / C-64C / C-128 machines, a 1571 drive or a nice working HESmon cart for C-64. Also looking for a Suncom TAC-2 and/or Slik Stik joystick. We'd have to do cash & trade up/down depending on what we're dealing with, of course. I'm an old horse trader, and I love to...

These drives came into my possession as part of a larger lot of vintage computer items. They are sans cables and PSUs, and as such, I have absolutely no way to test or exercise them. Externally, they show age and use - but no actual damage or abuse are evident. Asking $50/each + Actual USPS...

Looking for the matching external 5-1/4" floppy drive for a Tandy / TRS-80 1000 EX (Radio Shack IBM XT clone). The correct unit has an off-white "eggshell" color, with a slight pebbled finish. It should have a female 34-pin card edge connector on the end of the cable. Paying cash or offering...

Here we go.. first buy / sell / trade post! I'm wanting a working copy of HESmon for C-64 / 128. Doesn't have to be in box, or with manual - just the cartridge. In fact, the cart doesn't even have to be all that pretty, or even have a label if it's cheap. So long as the connectors are clean...

Howdy, I've got a copy sitting here, and it could probably be shaken loose with the right energy.. but for the moment, I'm unable to contact you personally. Looks like I need to get my post count up. So, keep an eye on your PM box. You should see something sooner rather than later. -L ETA: I...

Howdy folks, Hello from the Great State of Minnesota, which isn't precisely +the+ coldest place on Earth, but I don't think anyone around here would argue the point. It's been a real bugger of a winter, colder than a ditchdigger's ASP if you get my meaning. On the bright side, I've had tons...
