A little slow on the updates ;-) I've created a Gallery
section with pictures that I have collected. If you have anything to
add, send them my way.

New URL! I've grabbed the URL of http://www.compukit.org.
I am planning to include *any* information, articles, manuals, software, etc. for
the Compukit UK101 and the Ohio Superboard II computers. If you have any material
you'd like to see here, please let me know! Also, I've set up a mailing list for
discussions. To join, please send email to majordomo@junction.net
with the words "subscribe compukit" in the body.

Happy New Year! I fixed a bug I had in the CMP and SBC
instructions, and now I have a prompt! I get "DCWM_" appearing on the
screen! Now my problem lies in the keyboard emulation. Memory location 0x223
(I think) should contain the ASCII value of the key pressed, but I'm getting random values
in here. Anyone have any suggestions/working code for the keyboard emulation?

Work on my Compukit emulator is progressing. I now have a
mostly-working 6502 core. I decided to build one from scratch instead of taking one
of the publicly available cres out there. There's just a few subtle bugs I'm working
out (like the correct flags after an SBC or BIT instruction, etc). I've attempted to
run the ROM images I have on this core, but I'm getting stuck in the keyboard scanning
routine. I think that I've still got a buggy instruction somewhere...

I was looking through my old collection of magazines and happened to
come across an old issue of Practical Electronics - the July 1980 edition. In it is
a section titled Micro Prompt. It is a collection of programs and
tips for the Compukit. I have started to transcribe the article into HTML. You
can check out the unfinished article here.
