General Turtle TT2500

[Lars Brinkhoff]

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.
