But.. Those were pretty nice computers... Timex did make an incredible goof with those... Originally, it was intended to be an American Version of the 48k ZX-Spectrum Computer. But, as-is it wouldn't pass FCC regulations. So, they redesigned the computer to do so, and decided to "improve" it. Designing out most compatibility with the Spectrum in the process. With a set of Spectrum ROMS in a cartridge, and a "Twister" card (to convert the expansion edge back to the Spectrum version), one could use Spectrum Hardware and software on it. There were third party keyboards for it also, and when Sinclair was bought out, the company that bought it (I can't remember the name), made better versions of the Spectrum with built in Microdrives or Cassette Player, and a better keyboard. I have a U.S. Prototype of the Spectrum, a Microdrive interface and drive, and the Timex of Portugal 3inch Disk Drive System (which also turned it into a CP/M Computer). A nice computer for the time if you tricked it out a little. The company I worked for in the 80's even made a drawing program similar to MacPaint for it, called TechDraw, A Spectrum Emulator Cartridge, Disk System, Terminal Software (for the Timex Modem), and lots more... Also, fun days... I hope to spot one at a flea market to have one again. I still have my ZX-81 though. You can still get kits for the ZX-81, and some books and software from www.zebrasystems.com Regards, Al Hartman
