gferluga Posted May 26, 2021 Share Posted May 26, 2021 (edited) Dear all: Do you know if the CC9900 CorComp Floppy Disk Controller and the FinalGrom99 cart are compatible? As soon I select that cart, the system is freezing... Btw, where could I find a DSK image of the original CC file manager? Thanks in advance to all.

fabrice montupet Posted May 26, 2021 Share Posted May 26, 2021 Yes, the CC9900 is compatible. But you have to follow this way: - Press the space bar on the first screen - When the color bars are displayed, press any key for the next menu - Choose the FinalGROM99 (option 2) 1 Quote Link to comment Share on other sites More sharing options...

atrax27407 Posted May 26, 2021 Share Posted May 26, 2021 (edited) Has anyone checked the compatibility of a CorComp with the MG EPROMs? I thought one of the reasons that Miller's Graphics created the EPROM was that the originsl CoCormp FDC took control of the system at start up. The MG EPROMs, I think, removed it. (Further edit) Yep - the MG EPROMs remove the CorComp Title screen which causes lockup problems with some cartridges according to my notes. If you are interested, I can supply the MG EPROMs. Edited May 26, 2021 by atrax27407 3 1 Quote Link to comment Share on other sites More sharing options...

atrax27407 Posted May 27, 2021 Share Posted May 27, 2021 (edited) That is one that a bunch put together at a Chicago Fair a few years ago. I think Tony, Jon Guidry and maybe one or two others put it together. After they completed the code, I think it was Jon who came by my table and asked me to burn a copy for them to test. It worked and I kept a copy. I have those available as well. Edited May 27, 2021 by atrax27407 Quote Link to comment Share on other sites More sharing options...
NewcomerTI Posted August 26, 2021 Share Posted August 26, 2021 I have a question somewhat related and I’ll bet I need the MG eprom to solve this. If I insert a RAM card into the PEB it is not the startup of the system but rather the CC9900 screen as shown. If I’d rather start up to the RAM card what are the steps, solutions to ‘see’ the HRD first? Quote Link to comment Share on other sites More sharing options...
+9640News Posted August 26, 2021 Share Posted August 26, 2021 I'm guessing, but I suspect the HRD would need to be at CRU >1000 to be seen before the Corcomp at >1100. Beery Quote Link to comment Share on other sites More sharing options...

NewcomerTI Posted August 27, 2021 Share Posted August 27, 2021 Where can one get the eprom? Is the eprom right on the corcomp CC9900 board that needs replaced? I looked on arcade shopper to see if these EPROMs can be purchased there but didn’t see them. 1 Quote Link to comment Share on other sites More sharing options...

+9640News Posted August 27, 2021 Share Posted August 27, 2021 Be aware the eprom set for the CorComp was a 2 eprom set, not a single chip. 1 Quote Link to comment Share on other sites More sharing options...
RXB Posted August 27, 2021 Share Posted August 27, 2021 Yea I got like the third version of the upgrades for the CorComp Disk Controller. That menu originally was a stupid idea. Quote Link to comment Share on other sites More sharing options...

atrax27407 Posted August 29, 2021 Share Posted August 29, 2021 That is correct. The PEB card uses two 8k2764s designated as "Bank1" and "Bank2". The 9900CES uses a single 16K 27128. 1 Quote Link to comment Share on other sites More sharing options...
