Bridge card speedup
Message #104464
I have replacedthe 14 MHz clock crystal on the bridge card with a 24MHz crystal in order to accelerate the bridge card to 8MHz. Most everything seems to work fine except for two things. The a: drive will not access disk correctly. It gives a "Error reading drive a:" error…
Dave, Here are the exact messages when the bridge is booted with a V20. LPV1 at 0378h RAM: 256KBytes 0K E0000h Optional ROM bad Checksum=15h Error. Press F1 key to continue. What do you think? Forget about the V20? Mike
Dave, It doesn't matter anymore. I ordered a PC drive for my bridgecard. I do have another question and an observation. I tried replacing the 8088 with a V20. It didn't work. The PC window was garbled and the PC didn't boot-it said 'Boot error' or something. Is it possible…
Don, Yes, I saw that. I actually ground some of the back plate away so I could get the card in all the way. You would think Commodore would make a card that would fit their own computer. Not very good mechanical design. Mike
Don, I have a Percom Atari drive that has an edge connector to connect PC type drives. My second drive is a normal PC DS/DD drive. Anyways it doesn't matter now. The bridge card WORKS! I moved it to the other Amiga/PC slot and it worked. I reseated it before…
Don, Hmmmm, I have an old ds/dd drive I was using on an Atari 1200 system. I guess I could try it. Thats the only way to find out for sure! Thanks again. Mike
Don, I think I know what the problem is. From what I understand, one HAS to have the Commodore 5 1/4 internal drive. My dealer said that something is loaded from the drive(before the PC boot, I guess). I guess I will have to go out and get a floppy…
Don, I am using the startup-sequence that was copied from the install disk with no modifications. Yes, BindDrivers is the first command in the startup. Also, I do have many assigns-i.e. "Assign WB: sys:" and like "Assign c WB:c". I talked with my dealer about it and he said he…
#Bridgecard Help
Message #96505
I need some help. I just received a bridgecard today for my A2000, but I am having a problem. I followed the directions in the bridgecard manual to make a special workbench disk. I did not change any of the defaults for deleting wb files or adding the bridgecard files.…
Bob, Boy, that was easy!!! Thanks for the info. Mike

I have a question about a subroutine that you wrote. It is a file requester that is on the Aztec 3.4a examples disk. I am new with using requesters and string gadgets, so bear with me if I don't have the terminology correct. I incorporated the routine into my program…
#SLOW/FAST A2000 RAM
Message #93671
I took a program that I am developing on a A1000 with 2MB external RAM down to run on my dealers A2000. The program ran noticeably slower on the A2000. The A2000 has 1MB with the 2MB Commodore RAM expansion. The program flips thru 640x400x4 images stored on the ram…
Speedier bridgecard?
Message #93669
In the conference with Dave Haynie of Commodore, a question was asked if the 8088 on the bridgecard could be replaced with a NEC V20. Dave did not know for sure, but he thought it could be. Is there any other way to speed up the bridgecard, i.e. replace a…
