I have a box of 49 DC600 (maybe some DC300's in there) cartridges, plus one tape head cleaner cartridge. Some have been used to backup my MSDOS system back in the 90's. Some have labels on them suggesting that they contain UNIX-y things for Sun computers. That may or may not be true. I will bulk erase the MSDOS backups. If anyone is interested in these tapes, contact me. I won't want money for the tapes, just money to cover shipping, if needed.
