pcoderdude14 Posted December 30, 2017 Share Posted December 30, 2017 Hey there, All! I am trying to fix a CC DS/DD FDC and am in need of some clear pictures of the full assembled card, so that I know for sure if I have the ICs placed right, on the card. I have searched everywhere I can think of on the internet and have only found one website (from France) that has my card. Also...if anyone can help me fix this card it would be greatly appreciated. Thanks, in advance... Jt Quote Link to comment Share on other sites More sharing options...
pcoderdude14 Posted December 30, 2017 Author Share Posted December 30, 2017 OK...looked on the LINKS that were for "other websites" and found a PERFECT PIC from "mainbyte.com" of my FDC. Still could use some help with this Card though. Any ideas would be greatly appreciated. Jt Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted December 31, 2017 Share Posted December 31, 2017 The most common problem on a CorComp card is a blown TMS9901 (may be an S9901 on some boards, but that is a second-source TMS9901, so it is the same chip). I'd look at that first. . . Quote Link to comment Share on other sites More sharing options...

pcoderdude14 Posted December 31, 2017 Author Share Posted December 31, 2017 what are the symptoms of the card? The card's LED "blinks" when the FDC is accessed. The error message I get when I try to access a file, using it, is "I/O ERROR 00". I have tried using TI EXT BASIC module, and, access it thru "autoboot" to DSK1, without any success either. Just the "blink' of the LED , and, then ...nothing. Jt Quote Link to comment Share on other sites More sharing options...
Stuart Posted January 1, 2018 Share Posted January 1, 2018 Confirm that you're definitely typing the command as all caps? OLD "DSK1.FILE", not old "dsk1.file"? Quote Link to comment Share on other sites More sharing options...

+mizapf Posted January 1, 2018 Share Posted January 1, 2018 Confirm that you're definitely typing the command as all caps? OLD "DSK1.FILE", not old "dsk1.file"? One problem I noticed is that many people mistake the small capitals as capitals. Quote Link to comment Share on other sites More sharing options...
+arcadeshopper Posted January 2, 2018 Share Posted January 2, 2018 you will note he stated 'when i run extended basic it just flashes the card light' it could be a drive issue? is this a known good drive? how it it cabled? pictures/ Greg Quote Link to comment Share on other sites More sharing options...
Shift838 Posted January 2, 2018 Share Posted January 2, 2018 I have seen this error with bad drives, dirty cartidge ports and even a bad cartridge expander. I myself chased it for a couple.of hours before I figured out it was my cart expander. If you have a different drive definitely try to swap it out. Also if there is a speech attached remove it. Maybe reseat your flex interface card too.. Quote Link to comment Share on other sites More sharing options...
pcoderdude14 Posted January 3, 2018 Author Share Posted January 3, 2018 Hey All! :-) you will note he stated 'when i run extended basic it just flashes the card light' it could be a drive issue? is this a known good drive? how it it cabled? pictures/ Greg I have two drives, right now, hooked up to a WORKING Ti-FDC. Both drives work...one if on the "card-edge" connector, and, the other is on the 34-pin connector. When I try the CC FDC , that when I get the "I/O ERROR 00", and, absolutedly NO movement from the drives. Although,...when I "reversed" the cable on the "card edge" connector...(turned it upside down),...both drives LIT UP and stayed "ON" (the lights of the drives did, NOT the motors of same). So...I am thinking that I AM getting "power" to the drives THRU the CC FDC; I AM getting some working ICs in the CCFDC (the "flash" of the LED light, on the FDC); ...and, I KNOW that I have working floppy drives. So...(I guess) ... it must be the CHIPS (ICs) or the wiring of the CC FDC. Am I close? Happy New Year, 2018, to you guys, by the way Jt Quote Link to comment Share on other sites More sharing options...

pcoderdude14 Posted January 5, 2018 Author Share Posted January 5, 2018 Hey there! Well...after looking at the LAYOUT of my card, to the great PIC mizapf posted,...I realize that someone had been "experimenting" with the card, appparently. The crystal in the lower left-hand corner of the card HAS BEEN MOVED! I don't know what (or why) this was done to the card, but, now I guess that is probably where I am getting problems with the card. I don't have any oscilloscope, so I have no way to test if the crystal "circuit" is even functioning, or, not.... Anybody got any ideas? My first idea was to just RE-solder all the crystal "circuit" where it is suppose to be. Sound like a good idea? Jt Quote Link to comment Share on other sites More sharing options...
+9640News Posted January 5, 2018 Share Posted January 5, 2018 Is that two switches on the back of the 1985 Revision above the edge card connector for the external drive(s)? I never saw that card before. 1 Quote Link to comment Share on other sites More sharing options...

pcoderdude14 Posted January 7, 2018 Author Share Posted January 7, 2018 Hey again... Oh...btw... Does anyone have a list / schematic of the CC - FDC that show WHAT the capacitors, resistors, ICs, etc...are, since all of them seem to be "labelled on the card. Thanks,...in advance...

Jt Hah, good luck there! Unless something has popped up in the last couple of years (that I've been missing) I've never ever heard of anyone with a schematic of pretty much anything CorComp. I have yet another CorComp FDC, different that the two already posted. Although, the one with the two push-button switches has got me intrigued, never seen a CC-FDC with that arrangement. Any more info on that guy?? I'll try to snap a couple of pic's of my (I'm guessing prototype or very early design) CC-FDC. FWIW, it doesn't work either. And actually, almost sounds like the problem I had with mine. Let me dig that out. Will be back... -Dano Quote Link to comment Share on other sites More sharing options...

+jedimatt42 Posted January 7, 2018 Share Posted January 7, 2018 I think the rules are unique per forum, so that's the 'this community' part... In another thread they mentioned that the development forum has different aging rules for editing... Just throwing questions out there... You're website was built on a MAC, is your mac using .jpeg instead of .jpg? And is atariage stupid about that? -M@ Quote Link to comment Share on other sites More sharing options...
