I have prepared a new blog with wordpress at https://vintagecomputing.info !!!

Thank you.

Vince Briel developed already a lot of other interesting things like a working Apple I replica and a KIM replica (of course 6502 based, not 8080 or Z80).
Now he had a brilliant new idea ... building an Altair replica (with an emulated 8080 cpu based on an ATMEL AVR) ... I was a bit sceptical because an ATMEL CPU isn't a number cruncher monster, but it seems to work - hopefully at least with the speed of the original machine.
Also, I am curious about running CP/M on that machine, did not see any comment so far about it.


Here are the specifications:

Emulated 8080 run at speed or faster than original
32K RAM with BASIC loaded at power up (still in the works may have to load from SD card)
VGA or composite TV video output to a monitor
PS/2 keyboard
SD card slot to load/store software through terminal section
Battery option (not tested, may not work well with so many LED’s)
Diode circuit protection for battery/DC input.

Very nice design also, because you do not need an external terminal, just a VGA monitor and a PS/2 keyboard. Hopefully this project will get finished with a full success.
If anybody has seen screenshots from the working system (screen with CP/M or BASIC...), let me know where...
