I believe OSI used shift-O as the rubout function. I can't remember if any of the software platforms actually used the rubout key.

My C1P uses the RUB OUT key but SHIFT-O is working for WinOSI.

Thanks!

I have this graphics board that was for my Superboard. If I remember right, you could toggle the Superboard into bit mapped mode and regular factory mode. But I can't find the manual anymore and don't even remember who original made it. I'm thinking it might have been Aardvark. So I thought I'd post some pictures and see anyone else has an idea or the manuals.

Thanks
David

I have this board. I'm pretty sure it's a Mittendorf board. Unfortunately I do not have the instructions for it.

Thanks Steve. Yep it sure looks like the same board. At least now I have a name to search on. I'm still digging through any old stashes of manuals and stuff to see what I can find. You know how it goes when things and been in storage for years and been through several moves.

I just looked through some of my OSI papers and found a listing of my purchases. According to the sheet I paid USD$40 for a bare "High Resolution Graphics Board". It also says it was purchased at Aardvark, but also indicates it is a Mittendorf board. So, I added it to my web page:

Kinda interesting to see what things cost back then.
Please excuse my teen-age writing ;-)

Yes, that's the Mittendorf board. Thanks for the nice photos. If someone were to trace out the schematic, I could write something up about it, since I did a hi-res mod for my C2 that I think would be similar enough.

I imagine this circuit borrows signals from the video timing chain to sequence addresses to 1 port of a 2-port RAM; a data latch; and a shift register whose output can be OR'd with the OSI video shift register.

It would be great to reproduce one of these. Any chance of working with one of you to get one of these boards scanned?

Steve, It's been a while but I always enjoy browsing your 6502.org pages. Great stuff there--some really nice projects. I saw the color PET project on a Nuts&Volts cover at the local electronics store, and picked it up, but didn't have time to read the article. I didn't realize that was you!

Yes, it's a fun project for me. I'm slowly learning electronics on my own. I have so many ideas I don't know where to start sometimes ;-)
