Hello,
I'm making a software emulator for the General Turtle TT2500. Does
anyone have any information about it? It's hard to come by.
Here's what I have learned:
It's a custom TTL design by Marvin Minsky et al, with 64K 16-bit memory
and 4K 16-bit control store. It has two displays attached, one for
vector graphics, and one for text. There is a UART for talking to a
host (presumably running Logo), and a keyboard.
