Help! Does anybody out there still use a TRS 80 Model 100 with the "Portable Disk Drive II"? I have lost the one line of BASIC code you need to establish communication with the disk in order to load in the disk controller program "floppy". Thanks. -- --- cbs@gpu.utcs.utoronto.ca (Chris Syed)

Turn ON all 4 DIP switches on the drive. 2. Turn on the computer and the drive, and insert the utility disk. 3. Go into BASIC. 4. Enter this program: 10 OPEN"COM:88N1DNN"FOR OUTPUT AS#1 20 PRINT#1,"S10985157C00AD7EF08B3AS901FE" 30 LOAD"COM:88N1ENN",R SAVE"IPL.BA" 5. Hit F8 to exit BASIC. 6. Run IPL.BA from the main menu. Then you have to turn the drive's DIP switches OFF for normal operation. The drive's low-battery indicator blinks fast if you have the switches set wrong. -- David A.

Turn ON all 4 DIP switches on the drive. If I remember correctly, TPDD II does NOT have DIP switches. TPDD I does, so I believe the FLOPPY loaders are different.

Thanks to those who mailed or posted. Yup, no dips evident on the II... but it works fine at 19,200 baud... so really, all you need is the line that sets up that speed, and you're away. (i.e. run "com:98...") I guess there are some switches inside if you want to decrease the baud. :-) :-) -- --- cbs@gpu.utcs.utoronto.ca (Chris Syed)
