POWERTRAN CYBERNETICS
CORTEX

The information we have about this computer is sketchy.
O.S. was a powerful graphical BASIC interpreter modded from the TI basic.
Forth language was also available but not widely used.
Cortex had a mode to give 256 K RAM. ROM was copied into RAM at start-up and then swiched off allowing boot code and basic to be altered at start-up.

Cortex was followed by the Cortex II which was just a re cased version with same style as early apple/dragon 32 beige/yellow plastic sloping cases, but using same main board and disk drives.

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.

I have a Cortex 2, built from old stock kit last year. It''s running complete with the FDC and dual 5.25" drives from a BBC computer. If you have the missing copies of the Cortex user group magazine please visit http://www.vintage-computer.com/vcforum/showthread.php?15580-Powertran-Cortex and let us know.
