Received a new Games console a couple of days back and finally got around to testing it out today.
A Prinztronic Micro 5500 -
The power supply was DOA, but luckily with a bit of chopping & cable splicing I was able to use a spare power supply to test it out and it works absolutely fine! Just needs a fair bit of deep cleaning.
Came with 2 cartridges - Superstar 5001 (Pong-style games & target games) & 1007 Super Wipeout (Pong meets Breakout). I've also ordered the "1002 Grand Prix" cartridge for a simple racing game.
This console has absolutely no issues connecting to modern TVs and displays perfect colour.
Interestingly, even though all these PC-50X family consoles use practically the same hardware, there seems to be at least 3 alternative cartridge form factors in use. My Grandstand which doesn't work on modern TVs has 18-pin Cartridges, whilst this Prinztronic uses 16-pin cartridges. I've also seen 21-pin cartridges. A damn shame that there's very little documentation or interest for these systems as I'm sure a simple adapter could probably be created to fit the various different formats.
