- Oct 3, 2008Dear Kat,
Sierra Circuit Designs (http://www.sierracircuit.com/) has made a
VHDL version of the 1802. You might want to contact them.

Hi Fans of Cosmac Elfs,
I recently discovered this fancy little computer while searchig on the
web. I dont have a Real Cosmac Elf yet(Have digital ones though).
Lately, I have been thinking about writing up my own code (in C) to
simulate the Cosmac elf. I dont expect this project to compete with the
ones already available, just something with which I can undertand more
about the 1802 itself and improve and exercise my own (rather limited)
knowledge of C.
Can somebody give some suggestions as to how and where I can/should
Also, another idea rolling in my mind is, Would it be possible to build
a replica Cosmac Elf based on a PIC or has anyone already done this?
Long live cosmac elfs!
I was actually thinking of making an 1802 in an FPGA for the fun of it
(once I move a few other projects out the way and learn to use my fpga
development system) I was not going to write the code in VHDL instead do
a schematic entry system, this way it will be like doing it in TTL
gates, without the pain of making PCB's or wire wrapping, if I make a
mistake, it is very quick to change the system :)
Is anyone else interested in such a project ? This would not be a drop
in (with adapter) for an 1802 as I am thinking of clocking as fast as
the Chosen FPGA can go (kinda like an 1802 on red bull with a slab of
