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
