Getting Kermit onto the MBC-555

My Sanyo MBC-555 has been a good little computer, but it’s not especially useful. I haven’t been able to get software onto its strange disk format, and the software I do get can’t be run under DOS 1.25. If I want to test out a prototype serial card, I need to get Kermit onto the computer, and the best way to do that is to be able to write it to some disks.

Mouse in the Artdink House (Travelling to Tokio, Part 3)

With the NEC PC-9801RA2, I’ve fought bad power supplies, battery corrosion, case rust, weird NEC design decisions, and flaky floppy drives. The only thing that’s keeping me from enjoying my quirky Japanese space-simulation game, Artdink’s Tokio, is the lack of a mouse. How can “just go buy a mouse” turn into an entire article? You’re about to find out.

Breaking out of the Snail Maze

Snail Maze. Either you know what it is, or your video game system didn’t come with a free video game hidden deep within its logic board. Or you bought a later Sega Master System, which didn’t have it. But what if we could bring Snail Maze to those later Master Systems? What if, indeed?

Becoming Mr.PC's Type

Like the Sharp X1turbo, the Mr.PC is also not very usable without a keyboard. It’s yet another way in which NEC copied Sharp.

A Mini5 Hello World

Yes, it is finally time to sit down with the mini5HA again. My goal was to figure out how to make a working program for CP/M using its built-in assembler, and I wasn’t going to give up until I had at least a “hello world.”

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.

That name again is Mr.PC

Get ready to step into the cyberpunk future of the mid-late 1980s, and don’t forget to bring your boxed wine. NEC pulled out all the stops on this, their final PC-6001 computer. I have to pull out even more stops to get the disk drive to work.

All A-Keyboard for the Sharp X1turbo

Even though the X1turbo is working again, it’s not enormously useful right now. Sure, the boot screen is pretty, but there’s so much more to the entire experience. In order to take another step along the road to it becoming a functional computer, I’ll build a keyboard adapter.

Let's visit Portopia

In order to get to the bottom of a mystery, I had to put a lot of other mysteries in my way first. And then also build some hardware. At the end of this entry, I’ll have actually used old hardware to play a videogame. I’m scared too.

Make Your Own ColecoVision At Home (Part 1 - Design)

When I found some cheap ColecoVision cartridges in the junk bin at the flea market, I knew I had to save them from whatever fate awaited them after the junk bin. How would I play them? Today’s old-ColecoVision prices are ridiculous, so I started building one instead.
