Thanks for the input! Yes - the names, specs and everything surrounding the Laser/VTech-computers are shaky, to say the least! The Seltron 200 might come from one distributor, while other distributors simply imported the Laser 210 directly from Hong Kong, which seem to have been easy at the time.
There are, by the way, hardware hacks to get more colors and higher resolution - and they're not even that complicated!
