+ ftp://ftp.whtech.com/Powertran Cortex/
+ http://www.powertrancortex.com/index.html
+
+ Uses Texas Instruments parts and similar to other TI computers.
+ It was designed by TI engineers, so it may perhaps be a clone
+ of another TI or the Geneve.
+
+ Chips:
+ TMS9995 - CPU
+ TMS9929 - Video
+ TMS9911 - DMA to floppy
+ TMS9909 - Floppy Disk Controller
+ AY-5-2376 - Keyboard controller
