Here's a little do-dad:

I'd quite like to get CP/M running on my COLECO ADAM for giggles, but would need an 80 column upgrade to do it justice. 80 column board for the ADAM? Hah! No chance... But if I understand correctly said upgrade is really just a hardware serial console. Now I can't find any info on how the ADAMnet protocol works but for now I'm working on the above proof of concept.

Do you have any computer with a serial port?
Would you like a PS/2 interface for it?
Would you also like 80x25 text and graphics?
But don't want to loose any memory to mainting a screen?

Well, this should do, probably, possibly. Think of it as a hardware serial console with some extra bells and whistles. There's two ATMega's; one to run the Serial + PS/2 interface and the other to handle some local memory for a frame buffer and interpret serial commands for drawing to the screen, You never know I may even finish this one. ;-)

I thought I'd mention as this might have some useful applications.
