The first resistor you proposed to cut is not S1 (yes, S1 is far away from S2, just on the left of the 'black thing') is E2,
In retrocomp.de info you could find:
Set the E2 strap to the ON state only if your computer requires MASKING THE INDEX. (i.e. PC and older PC/XT that do not give the drive enough time to reach a ready state when the disk replaced.
I cut this resistor and BINGO! Everything works!
Sadly NO, it doesn't work. This is the behaviour right now:
- 360 Kb floppies, I put a floppy, dir A:, sowing the content...
- Change the disk
- Dir A: again... SAME INFO, missing change disk signal?
I'm pretty sure that I need to change some other straps, I found a picture of the same board with OTHER jumper configuration... Could it be the right one to put this TEAC in a PC? In red the main differences with mine
This is my board, In red the jumpers that are absents in the order board, in blue the resistor that is absent in my board.
I coulnd't find useful info about S4 jumper, nor about HS (head selector), R25, R26, SII, R29... I think I'm going to CUT the jumpers and try again in this order:
S4
SII
HS
