Does anyone have the pinout for the Floppy Disk Drive port on the back
of the Toshiba laptops? I'd like to skip the high cost of one of their
floppies...

All users of Toshiba PCs should take advantage of what I consider to be an excellent customer support system. The best part is that it's free! Toshiba operates a bulletin board dedicated to supporting their personal computer product line. The phone number is 714-837-4408 and they support 300/1200/2400 bps. Two of the files that you can download from this BBS are called 3100-IBM.TXT and OTHRCONN.TXT and they describe the disk drive cable and the connector pinouts, respectively. For your enjoyment, they are included below: ------- File 3100-IBM.TXT 1100+ or 3100 to IBM Floppy Disk Male DB-25 to 34 pin Card Edge connector 1 33 & 34 2 8 3 26 4 28 5 30 6 to 9 nc 10 12 11 16 12 22 13 24 14 nc 15 32 16 18 17 20 18 to 25 All odd pins -------- File OTHRCONN.TXT RGB Connector 1 & 2 Ground 3 Red 4 Green 5 Blue 6 Intensity 7 Not Used 8 Horizantal Sync 9 Vertical Sync Printer Port | Floppy Port | 1 Strobe O | 1 External drive Ready I 2 Data 0 O | 2 Index I 3 Data 1 O | 3 Track 0 I 4 Data 2 O | 4 Write Protected I 5 Data 3 O | 5 Read Data I 6 Data 4 O | 6 Disk Change I 7 Data 5 O | 7-9 Not Used 8 Data 6 O | 10 Drive Select -B O 9 Data 7 O | 11 Motor On -B O 10 Ack I | 12 Write Data O 11 Busy I | 13 Write Enable O 12 Paper End I | 14 300 Kbps Data Rate O 13 Select I | 15 Side Select O 14 Auto Feed O | 16 Direction O 15 Error I | 17 Step O 16 Printer Init O | 18-25 Ground 17 Select In O | 18-25 Ground | -------- Make sure your disk drive is jumpered as drive "B" (DS1). I took this one step further with my 3100. The controller in the 3100 will support 1.2MB drives, so I added the extra wire between DB25 pin 14 and edge connector pin 2. I mounted two drives in one box and set up a toggle switch on the drive-select line to switch between the 360K and 1.2M drives. When switching between drives you also need to run the Toshiba-supplied TEST program and change the setup for the second diskette drive.
