OK, some things about Little Red Reader: [a program for the commodore 64/128 that lets you read PC disks] LRR was originally made for the C128 and a 1571 [DS/DD drive]. A 64 version [which requires a 1571 drive] supposedly exists, but I cannot vouch for that as I own a 128. The program basically reprograms the 1571 [or 1581] to allow it to read/write MFM format disks [in this case IBM] The program will read and write 360k IBM format on a 1571 and 720k on a 1581. Yes, the program can "go both ways", that is, it can copy CBM to IBM and the reverse as well. As for reading MFM format disks on a 1541, this is generally thought to be impossible because the 1541 only reads GCR format disks, not MFM. BUT!!!!!! There is a hardware modification and a companion program that does allow one to copy a PC format disk. Ask somone on the newsgroup where to find it though, as its wherabouts has slipped my mind. ALSO, besides the X1541 procedure, there is another hardwrae mod for a PC type drive that enables it to read commodre disks. Please dont ask me specififcs, I really dont know how this was/is accomplished. Hope this clarifies things! MM
