Hello,

I'm writing a simulator for the General Turtle TT2500.  I have various
informal descriptions, an assembler, and some software.  If anyone has
any information, or photos, etc, I'd love to see it.

The processor is a custom TTL design with some pipeline hazards exposed.
There are two displays: one for text and another for vector graphics.
There is an UART and a keyboard.  The software accepts input from the
UART; text with Datapoint cursor codes goes to the text display, and
turtle graphis commands (including SPIN and GROW) to the vector display.

Best regards,
Lars Brinkhoff
