Posts tagged "Clones"

A ‘clone’ is a compatible replica version of an existing system, often developed in my case because the original was hard to find, or simply too expensive.

Dick Smith's Wizzard-ry 8 (Bit)

Sure, I’ve cloned TI TMS99xx-based systems before. There’s the ColecoVision and the Sega SG-1000. But those were all Z80s, and it’s important to diversify my interests a little bit. Luckily, VTech released a little 6502-based system called the CreatiVision, and let the schematics get out.

The Soggy-1000 turns a page

For version 3 of the Soggy-1000 SG-1000 clone, I wanted to make it more useful as a general-purpose computer. Building a new keyboard is going to cost a fortune in parts, so it’s fiscally prudent to find more reasons to use said keyboard. There are only so many SG-1000 games out there, the SC-3000 software library is kind of small, and I was using only 2k of the 32k of RAM that I had on the board. These are all problems that can be solved with a suitably large application of hubris.

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…

Make Your Own ColecoVision At Home (Part 4 - Quadrature Controllers)

We got conventional ColecoVision “hand” controllers working well in the last entry. I’ve never used any of the ColecoVision’s more exotic controllers before; will they work properly on my clone machine, even though I didn’t really understand them?

Make Your Own ColecoVision At Home (Part 3 - Joystick Fix)

In the last entry, I was left with a working ColecoVision-compatible board, albeit one with a very stuttery controller that would only work when connected to what I thought was the second controller port. Let’s fix that, and then enjoy the cheapo ColecoVision games that I spent all this effort building this thing for in the first place.

Make Your Own ColecoVision At Home (Part 2 - Assembly)

The boards for the homemade ColecoVision clone project have arrived. It’s been a long haul of finger-burning fun to get the console assembled, but will it ever be able to play a cartridge?

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.
