Multiple floppies in one system?

JDR's own line of parts (forget the name) used to sell an ISA 4 floppy controller, they still might. Only machine (that I remember) that supported more than 2 floppies was my Sanyo MBC-555-2, went to 4 but then a hard drive defaulted to E:. Easy enough to get used to but the fact it had 4 floppies and with aftermarket DOS could go to 800k 5.25" format, I was able to run a Fido BBS system locally without a hard drive on it - Hacker's Anonymous out of UofI Champaign-Urbana, until they gave us an IBM AT with 2 20mb hard drives in the Theoretical Chemistry lab. => -----Original Message----- => From: owner-classiccmp(a)classiccmp.org => [mailto:owner-classiccmp@classiccmp.org]On Behalf Of David C.
