Re: OSIWeb.org wish list :-)
Actually on my board it did connect to the original video circuit. That was what the smaller ribbon cable was for. On the end of it was a small PCB with solder tabs. From these were some 30ga wires that ran to various points on the Superboard. Unfortunately over the years they had all come lose and...

Dave,
I just scanned and uploaded "TinyCompiler1.3.pdf" to your drop box. Not sure if it's the same version you mention you're looking for.

Re: OSIWeb.org wish list :-)
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 addr...

Re: OSIWeb.org wish list :-)
I have this board. I'm pretty sure it's a Mittendorf board. Unfortunately I do not have the instructions for it. http://www.6502.org/users/sjgray/computer/osi-c4p/TOSIE-hacker-back.jpg Steve Steve, It's been a while but I always enjoy browsing your 6502.org pages. Great stuff there--some really nic...

Re: OSIWeb.org wish list :-)
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: http://www.6502.or...

Re: My C4P Project
Not much progress to report... still planning things. However, since I was in an OSI mood I decided to make a small project webpage: http://www.6502.org/users/sjgray/projects/osi/index.html Right now it's just a place to put thoughts, schematics, links, etc. There is a pdf of my 540B board that's a ...
