I could use up to four Disk [ drives, or clines that interface tot he standard Disk ][ card, for some systems that I am working on.
I have a spare DuoDisk as a possible trade, if that interests anyone. I personally like Ace A10s, and the turn-level style clone drives, if you have those. Otherwise, stock Disk ][s will suffice. I only care that the drives connect to a standard Disk ][ controller--becasuse of some things that I am doing that require this.
If anyone happens to have a Disk ///, please LMK. I would like to try something with one of those drives, as well.
