I decided to bring out my two Commodore 8032s. One of them works (after I replaced a RAM chip) and one of them does not. I figured I could use the working one to help diagnose the one that doesn't work. However, I'm hitting a bit of a wall. Here's what I've got figured out so far... The...

I bought a batch of S-100 stuff from the thrift store for a great price, mostly Cromemco stuff. Unfortunately, it's a bit incomplete, so I figured I'd work towards getting some stuff to make it functional so I can play with it. I found a backplane for a good price which is currently on it's way...

So I've embarked on the mission to get my BBS on the internet via telnet. So far so good. Got it connected to a virtual modem in linux and I can telnet to it via my home network. I knew I was in for a challenge getting to work over the internet. I have a Dynamic IP through my ISP, so I looked...

I recently decided to try booting GEOS on my crazy expanded C128-D figuring it would be a good experience, but I end up getting an error. Anybody have a clue what this means?

So I'm back working on the Altair. The RAM is good, I can read & write to it, but when it comes to executing anything, it's not doing a damn thing. When I reset, all the status lights look good (MEMR, MI, and WO are lit). When I single step, the STACK LED will light up for the next two steps...

So I watched the 8 Bit guy talk about the Maximite computer which uses BASIC. He didn't go into much detail, so I figured I'd look into this interesting board. This thing is freakin' awesome! This version has a spot for prototyping...

So it appears that I got my Altair 8800 working (from a completely non-working state), but the problem I'm having is the D0-D7 LEDs are always in the on position. Hard reset works, stepping through the addresses works, but reading and writing to them do nothing to change their state. I've never...

I just bought a Compaq Portable off Ebay. From what I've seen, it has the same style keyboard as my Kaypro with the deteriorating foam pads. This computer is going to have a much needed purpose, and I'm going to be hammering away at that keyboard quite a bit. I was wondering if it's physically...

I finally got both my drives working on my Model III. However, it seems to be having problems with data starting at track 21 and higher. This is for both drives, and all operating systems. It won't backup disks past cylinder 21, and it complains when it's formatting a disk past that point. I'm...

I couldn't resist buying this thing, even though I suspected it could be an obsolete piece of useless crap. It's basically a dumb terminal for your smartphone. It powers up fine, and that's the extent of it. From what I can tell, i may be able to turn it into a crummy laptop with an old Windows...

Looking for a Compaq Portable. Preferable if it has a hard drive, but not necessary as I have one I can put in it. Preferably located in Canada to reduce the pains of shipping prices, but will purchase from the US if the price isn't too bad. Doesn't need to be re-capped, as I can do that.

I've been thinking about purchasing a Compaq Portable (the original one). A lot of the configurations I see have two floppy drives, but some have hard drives in them. Is it fairly straight-forward to install a hard drive controller card and a drive? I have a couple kicking around that I could use.

I would love to see a registry for the Altair 8800 just to see where they are in the world and how many are currently out there. It looks like some people did start registries in the past, but I can't find a single one currently online. Does anybody know of one currently online that I'm perhaps...

I got this card in a batch of Apple II stuff. Does anybody know what it's for? I can't find anything on it.

I picked up a Tandy 1000 for $10. It's in very nice shape. Every time I try to launch certain applications, it asks me to insert a disk with the file compress.res into a drive. Why does it ask this? I'm guessing some things may have been deleted and it needs an install disk. Can anyone confirm?

I scrounged up a couple of Macintoshes that were sitting in the rain. One of them is a Macintosh II. After a cleanup, I was able to jumpstart it with a 3v supply. However, I cannot get any video because I don't have the monitor for it. I have one of those VGA adapters with the dip switches, but...

After buying my Altair 8800 locally, I really started to wonder how widely those early machines were distributed. The person I bought it from purchased his kit in the USA back when they were being sold. That got me thinking about how uncommon computers like the Altair or the original Apple would...

I've come into a situation where I may be able to buy myself an Altair 8800. The only catch is... it apparently doesn't power up. Since I'm not afraid of tackling electronic problems, I'd like to have a look inside the machine before I decide whether to buy it. Is there anything typical that...

I've got a Video Toaster card in my Amiga 2000. It works, but from what I've learned, I need to have a TBC to sync up the video inputs. Am I correct in believing that I need a separate TBC card for every single input?

I've ordered myself a full-height Tandon 360k floppy drive. If I just stick it into my model III, does it actually function like a 360K drive, or will it function as a 180K drive? If it functions as a 360k drive, then perhaps both of them should be changed over to 360k
