jchase1970 Posted January 13, 2012 Share Posted January 13, 2012 I bought a 3.5 inch drive from tex-in treasures last year, just plugs on to the disk controller card on the expansion. Have not tried to transfer from ti to pc or vise versa but that was my intentions. If I remember it was only about 30 dollars. Quote Link to comment Share on other sites More sharing options...
KirkDCO Posted January 13, 2012 Author Share Posted January 13, 2012 That sounds like a viable option. In response #8 of this thread, Ciro pointed me to TI99-PC which appears to also support 3.5" disks. Quote Link to comment Share on other sites More sharing options...
ti99iuc Posted January 13, 2012 Share Posted January 13, 2012 yes, i done the same work for some disks. into my PEB i have: drive 1: floppy drive 5.25" drive 2: floppy drive 3.5" drive 3: HxC Sd Card Drive so i done a copy from 5.25" to 3.5" and from pc i can read the 3.5" floppy using Ti99-pc program. the floppy drive must be a 720kb drive not an HD 1.44Mb... (this one could not work on the PEB)... and it will be formatted at the same of a 5.25" floppydisk. on pc you should install the omniflop driver on windows. after that the normal pc formatted disk will be unreadable and you will read the ti99 formatted disks using TI99-PC.

KirkDCO Posted January 13, 2012 Author Share Posted January 13, 2012 Nice! I think I've found a 3.5" drive that should work in the PEB. I just have to get it all in my hands and try it out. I'm sure I'll be asking questions again. 8^) Quote Link to comment Share on other sites More sharing options...
ti99iuc Posted January 13, 2012 Share Posted January 13, 2012 (edited) Perfect, put the drive like a Dive number Two so you do not need to modify the flat Cable. Here in Italy it's 24.15 o'clock, so i will go to sleepppp !!! Good night Edited January 13, 2012 by ti99userclub Quote Link to comment Share on other sites More sharing options...
marc.hull Posted January 14, 2012 Share Posted January 14, 2012 the floppy drive must be a 720kb drive not an HD 1.44Mb... (this one could not work on the PEB)... and it will be formatted at the same of a 5.25" floppydisk. Actually the Ti can use 1.44 HD drives with no modification on the TI provided you either jumper the HD detection switch on the drive or use DD (720K) floppies. Using HD floppies also works provided the HD detection is defeated but they are very unreliable and prone to data loss in my experience. They also seem to have problems on the PC side with unreliability when used as DD disks instead of HD ones. I have also found that when used in conjuction with 5.25" drives on the same cable then the physical order of the drives should be 3.5" first with the 5.25" at the end of the cable with proper termination. IE....... FDC -> 3.5" -> 5.25" -> termination. I have a theory that the 3.5" drives aotu termination does not work well for the older 5.25" drive and will shell it out after use (could just be that they are old and prone to failure.. Good luck...
