Hi everyone, the laptop it came from is an old compaq contura 430cx, the suspected pin outs that I have sofar appear below, this is from comparing the pins for the floppy connector in the advantech biscuit pc users manual with the pins given on the citizen web site for there laptop floppy drives. Hopefully in the next few days I'll be etching a pcb to test the theory, ill report on whether I get a boot drive or smoke! The motivation for all this is that since the hard drive is dead and im running short on dollars I figure the 64 MB of ram that's onboard should be sufficient to hold the processors playground, so if I can get the floppy running Ill beable to use a linux boot disk, load everything on to a ram disk and then swap the floppy's over and use it as a scratch pad till I can aquire a decent harddrive,(sort of like the olden days but with 64mb and a 233/586) regards Shane Any corrections would be appreciated before I see smoke! ######################################################################################### pin assignment floppy pin assignment floppy pins ----------------------------------------------------------------------------------------- 1 GND 15 2 Density Select 11 3 GND 17 4 N/C ___7/13 (laptop reserved pins) 5 GND 19 6 N/C ___13/7 (laptop reserved pins) 7 GND 21 8 Index 2 9 GND 23 10 Motor Enable A 10 11 GND 25 12 Drive Sel B ___ignored since B drive 13 GND 14 Drive Sel A 4 15 GND 16 Motor Enable B ___ignored since B drive 17 GND 18 Direction 12 19 GND 20 Step 14 21 GND 22 Write Data 16 23 GND 24 Write Gate 18 25 GND 26 Track 0 20 27 GND 28 Write Protect 22 29 GND 30 Read Data 24 31 GND 32 Head Select 26?
