rocky007 Posted March 21, 2011 Share Posted March 21, 2011 Pff, bad news.. this morning i at least found a working 3"1/2 disk drive, and working with TI99 (Thanks opry ). I used it perfectly, copying disk from 5.25 to 3.5 without trouble. After, i tryed HxC card a little, to make some test. This evening, i try to reconnect everything, and....TI99 don't want to start anymire : blocking on blue screen before the welcome screen. I tryed the follwing things : - disconnecting all drives : blue screen - connect only the original TI drive : blue screen - removing 32ko, RS232 card from PE BOX : blue screen - removing the floppy controller : working, have access to menu - .. inversed the floppy cable ( between the floppy controller and the drive ) : have access to menu, but of course floppy don't work So, i suppose my disk controller is dead Have you idea ? Is somebody here have a disk controller to resell ? Thanks Quote Link to comment Share on other sites More sharing options...
unhuman Posted March 21, 2011 Share Posted March 21, 2011 Since I don't have a PBOX - and I'm a little unclear on what you attempted... - .. inversed the floppy cable ( between the floppy controller and the drive ) : have access to menu, but of course floppy don't work So that makes it sound like system works with controller card in... One thing I do recall is that the drives have to have shunts or something - drive 1 needs to know it's drive 1 and drive 2 must know the same thing. I don't recall if there needed to be a terminator or something too... Good luck! Quote Link to comment Share on other sites More sharing options...
rocky007 Posted March 22, 2011 Author Share Posted March 22, 2011 sorry if i wasn't clear : the terminator is correct : basically, the PE BOX had 1 floppy drive (the original TI drive). When i connect the TI drive to disk controller, it don't work. When i switch on the TI99, i just have one blue screen. When i inverse the floppy cable ( normally, it's forbidded )...the TI99 switch on, but of course reading a disk don't work. When i disconnect the floppy drive, i also have a blue screen. From my previous test, even when the terminator not good, or no floppy connected, the TI always start...but have error when trying to use a the floppy drive.

Thanks If your system starts regularly without the FDC in but freezes when it is installed then I would guess your FDC has bit the dust, TI model correct ? I would ask as to how you had them cabled (one cable per drive or chained on one cable) and how the 5.25" drive was terminated ? I have an Extra TI FDC if it turns out you need one.

rocky007 Posted March 23, 2011 Author Share Posted March 23, 2011 i set it like origine. One cable from disk controller ( TI ) to TI floppy drive, with the good termination (i never changed the termination ). So, i think i killed the disk controller after trying the HxC emulator. Since i tryed it, the TI freeze. Can you make me an offer in PM, shipping to belgium thanks Quote Link to comment Share on other sites More sharing options...

rocky007 Posted March 24, 2011 Author Share Posted March 24, 2011 it's a floppy disk emulator. Using SD to store floppy image. The advantage is it's compatible with nearly every computer using standard floppy connector ( Atari ST, Amiga, PC, TI99 , MAc, etc..) http://hxc2001.free.fr/floppy_drive_emulator/ Quote Link to comment Share on other sites More sharing options...
