I appear to have found a 3B2/400 floppy disk drive substitute, which means that for me, my 3B2 floppy troubles are now over! I 'think' I have just successfully 'hacked' an ordinary 1.2 Meg PC floppy disk drive to work with my 3B2/400 computer. So far, I have just formatted/verified/created file systems, mounted them, as well as mount disks formatted under the 3B2's old original floppy disk drive. This also implies that it might be possible to interface a 720K 3.25" floppy disk to the system as well...? Hmmm, I wonder if I can 'hack' 2 floppies onto this box? <GRIN> Any Suggestions??? I will run like this for the next few weeks, and verify that this sucker is in fact working perfectly. If anyone has managed to get two floppies drives interfaced, I would really be interested in heaaring about it! If it is possible, I can see myself interfacing a 720K 3.25" drive as a second disk drive. The 'exact' drive I am using is a Panasonic JU-475-2AGJ drive, and all did was move the DC jumper to RDY, and moved the CX jumper over to BX. The drive must setup to use Drive Select 0, and the terminating resistor MUST be installed. If you are not that great in the 'hardware' department, then I suggest you do not try this....

I had to change AX junper to MX and MS to EX and everything is working find. This beast is a 1.6 meg drive and what it's used for I don't know. I do believe the drive AT&T uses for 3b2 series is a Panasonic (at least this is what I have been told by a AT&T dealer). Now if I could just find out how to add a second drive without getting the full kit from a VAR dealer, I would be happy, at least for about 5 minutes. -Cyro -- Cyro Lord Alpha Comm. Dev.
