[Coco] PCs pretending to be drive boxes wasRe: Drivewire question

[Derek]

I should have made it clear, on the C64 cable it is used to get disk images on a C64 disk, not using the PC as a disk image server. If anyone knows of a program for the PC and C64 that does act as a server please let me know. I have yet to find a very reliable program to get the disk image to real 5.25" disk working. I kind of gave up on it and have put my C64 up on the un-used systems shelf for now.

Really?  Can you be more specific?  I built my own parallel bit-banger 
cable for the C=64 and it works just fine for me.  It cost me $0 to 
build, since I had the parts lying around.  I don't remember all the 
details ATM, but I think I can find the info I used.  Maybe when you say 
"building one" you are referring to that specific interface.  I'll buy 
that.  But you can build a working cable for cheap to nothing with no 
surface mount components and no PC board.

[Thinking... remembering...]

Maybe the cable I have only interfaces a 1541-compatible disk drive to 
the PC and not the PC to the C64.  I know I used it to get disk images 
onto real floppy disks.  Now that I think about it, I don't remember 
whether or not it can be used to serve disk images directly to the C64 
without a disk drive.

Maybe I'd better hook it up again and refresh my memory...
