  Call In The PROs To See Things Clearly (X68000 PRO Part 4)

  

  A small update on the X68000 PRO that was saved from an inglorious death over the course of the last three articles. It’s gotten a video configuration that works properly. I know, that’s way cooler than painting the case, right?

  An SG-1000 II gets a second chance

  

  As we’ve covered before during the clone saga, the Sega SG-1000 was an unfortunate casualty of the Nintendo juggernaut. But surely the redesigned SG-1000 II would do better, right? No.

  Sanyo Triple Five

  

  Even though I seem to have terrible luck with x86-based computers, that doesn’t mean I have to take it lying down. I can go out there and cause even worse things to happen to me. Like, for instance, buying a broken super-budget PC-incompatible from 1982.

  Another try at fixing the Magic Smoke SE

  

  A few years ago, I got the “Magic Smoke” Macintosh SE. It was a pretty rusty machine, but otherwise looked okay inside. However, when I plugged it in after a (very) cursory inspection, it made ugly noises, failed to start, and then spat out a little bit of magic smoke – hence the name. Ever since then, it’s been a really small piece of furniture. I’m going to rip it apart and fix it.

  A Supergun for All Seasons

  

  Playing arcade games at home. That’s the dream, isn’t it? Maybe get a little Columns action on the desk you usually use to do taxes? Perhaps you can even make a little test bench, get a bit of board fixing going? Yeah, that’d be really cool. Too bad nothing like that exists, and especially not well-tested and open-source. Wait, it does? And it is? Well, then, we’re just gonna have to build one.

  Soggy-1000 ][

  

  Once I got the Soggy-1000 playing SG-1000 cartridges, the next thing to do was to extend it. In this phase of the project, we’ll take that leap from “interesting” to “slightly ridiculous,” by adding the feature I’m most excited about – at least until I get excited about a different one – the SK-1100 keyboard connector.

  SG-1000 Ways To Leave Your Original

  

  The SG-1000, being Sega’s first home console, has appreciated quite a bit over the years. Its price is now faintly ridiculous, especially when you consider its successor, the relatively inexpensive Mark III. Luckily for us, this console is made out of off-the-shelf components, virtually all of which are also found in the ColecoVision. If only we knew someone who’d cloned the ColecoVision…

  More Memories of Pictures

  

  Back when I did the recap, power supply recap, and trace repairs on the Bad ADB Mac LC, there was something missing. Even after all that work, I was only left with a measly 16 colours at 640x480 resolution. That’s not enough colours at all, but luckily it’s pretty easy to fix.

  Bluer than velvet were her SCSIs

  

  If you need a SCSI hard drive for your old computer, there are a lot of great options becoming available for a solid-state substitute. A great one of those options is the BlueSCSI, and I’m not just saying that because I won a free one. It’s because I won a free kit, so I got to put it together myself.

  Call In The PROs When You Can't Flop (X68000 PRO Part 3)

  

  With a new power supply and the entire insect population of Honshu removed from its case, the swamp-bogged X68000 PRO can finally start up, but can it boot floppy disks? In this exciting conclusion to the series, we’ll jump through a frankly ridiculous number of hoops – many of them ultimately proving to be unnecessary – in order to make some disks and find out.

  Go Back to GBS

  

  There are a lot of people buying fancy upscalers these days. And who can blame them? Old videogames are great, but new monitors are lazy and inept. What, the signal is too slow for you? Clearly all these great old arcade boards, computers, and game consoles are just not a big enough challenge for the input logic in modern LCDs, who prefer to spend their considerable brainpower decoding much higher-frequency syncs. To solve this problem, I’ll spend not very much money.

  Call In The PROs When You Need Power (X68000 PRO Part 2)

  

  Now that I had a reasonably clean X68000 PRO to work from, I set about restoring power. Rather than doing things the cheap way and strapping up my Meanwell four-voltage test supply, I decided to go whole hog and lay out a brand-new power supply PCB.

  Set Sails For Piracy!

  

  Have you ever wondered how it’s feasible for AliExpress sellers to produce knock-off Sega Genesis cartridges for under five bucks? I sure was, so I bought one and then tore it apart for your edification. You can thank me later.

  Call In The PROs When It Gets Dirty (X68000 PRO Part 1)

  

  What happens when you bid on a Sharp X68000 PRO without looking too closely at the photos? For one thing, you win the auction. What also happens is that the computer spends a while in your garage, waiting for all of its little tenants to be vacuumed out.

  Raising the PC-8801MH

  

  Hirofumi Iwasaki’s book on PC-8801FH/MH repair says that the head loading solenoid is so loud that you should be careful using the computer in an apartment at night, lest the neighbours complain. I am not hearing that, or any other noises from the floppy drives. Let’s investigate.
