I fixed up my SC-3000’s cartridge slot almost a year ago, but I haven’t been using the computer. Why not? Because the keyboard is super unusable. It’s time to fix it now, though, because I just paid a king’s ransom for a copy of Flicky.
Without a working keyboard, the CoCo that I’ve been working on over the past few months might as well be a fancy desk ornament. When I took a look at the keyboard last time, the membrane had some pretty serious damage to its carbon conductive traces. Before spending money to replace the keyboard, I’m first going to try and fix those traces with the conductive paint I already paid for.
When I first fixed the PC-6001, there were a few sticky keys on the keyboard. “H,” Left Shift, and - most importantly - Return were all bad to a certain extent. I could limp along with Ctrl-M for a little while to replace Return, but it was pretty awkward. How hard can it be to clean the keyboard?
When I got the CoCo up and running in the previous entry, I noticed that the keyboard wasn’t working particularly well. I found myself with some spare time to dismantle the keyboard, and unfortunately it has not yet been fixed. That doesn’t mean we can’t still learn a thing or two.
The internet is both really good and really, really bad for my hobby. On the one hand, it lets me buy cheap broken computers and shows me how other people fix them. On the other hand, sometimes people offer me machines and then I take them.
I finally got a keyboard for my PC-8801MH (I was on the verge of making one myself), and had to settle for a very dirty one as prices are just a hair shy of ridiculous. Even though I was primed by the pictures, I was shocked by just how disgusting the keyboard for the MH was when it arrived.
My PC-6001 came cheap because it was untested (and it did end up needing capacitor replacement), but the PC-6001mkII seems like it has always changed hands for a lot of money in Japanese collector circles, at least for as long as I’ve been paying attention to the prices. When I landed one for a great deal, I figured that there must be something wrong with it.
I removed the clock battery from my X68000 ACE, sped up my PC-98’s video, and got a keyboard for my PC-8801MH. Come enjoy this bite-sized collection of what’s going on with my machines.
Another postie-threatening crate arrived on my porch this week. There’s a lot of projects in this one; I’m not even sure a single one is “usable” as-is. This one sort of got away from me, but those are the fun kind!
Some more mini updates for things that weren’t big enough to merit a full update on their own. In this entry, we’ll finally get A-Train III running on my PC98, fix an Atari ST keyboard, and ship new hardware for a whole new brand of Japanese 8-bit computer.
When I first got the HB-101, its combination of small RAM and lack of any way to get software on it was a problem, sure. There was a bigger problem waiting, though: the grim spectre of an inconsistent keyboard.
A few years ago, my friend Grant completed a refresh of one of his Model M keyboards (I know, right?) Here’s his writeup on the process.
Japanese Santa dropped by my house earlier this week and left behind a back-shredding 40lb box of microcomputer goodness. Let’s investigate.
I’ve had my Apple IIe for a few months now, and it’s been great. One of the things that’s kept it from getting more use has been the spotty “I” key, which the seller warned me about.
Going to try a new format for this entry; there are some small updates to keep a record of, but nothing deserving of a full entry on their own.
The SparcStation 1+ is still pulling its weird “Illegal Instruction” error, but at least now we know the keyboard works.
The replacement keys for my battered C64 arrived from Retroleum. It took a bit longer than I expected, but then again the postage was ridiculously cheap and it wasn’t like I was biting my nails waiting to play with the C64 I’ve had on the pile for a few weeks now. I’ll definitely be back to get more parts from them.
I’ve decided to start working on the “bad” Atari ST, with a non-functional keyboard and floppy drive, before I tear into the “good” 1040ST I just picked up.
Many years ago, I got ahold of an Atari 1040STF for really cheap. However, I didn’t have any monitor to use it with, so it has sat in storage for quite some time.
In a previous installment of the SparcStation 1+ saga, I got the machine to present a serial console to one of my other old computers, but couldn’t get any video out of the video card or boot to an actual operating system.
A power supply arrived from Ray Carlsen, and it works great. I spent the time while I was waiting by soldering a really bad video cable. I only managed to melt one DIN plug in the process!
If all goes well, I will soon be the owner of an NEC PC-8801mkII “Model 30.” The platform is famous in Japan, as later models of the PC88 featured a ton of independent games, including many from developers who would go on to create games that were popular worldwide (Thexder, Snatcher and Ys all got their start on this platform). It also has a lot of trash, but neither of these things are interesting to me right now. I’d be happier just getting the computer to work (not least, because as a non-SR mkII, there are very few games I can enjoy on it anyway).
I picked up a Commodore 64 off the local classifieds. It came with a 1541 floppy drive, a bag full of blank floppies and tapes, the C64 itself, the infamous black finned power supplies that kill C64s, a Rixon modem, and a Nortel multi-line keyset from the 90s.
The keyboard I got with my Amiga 2500 had:
- A broken right alt key,
- A spotty (at best) return key,
- And a numpad enter key that wouldn’t stay up, but did work,
