![]() I also swapped the drive-select jumper on the Gotek itself from S1, which it comes stock as, to S0. Pin 1 is red, and delivers five volts, so don’t get it backwards. Plugging it in isn’t too hard, assuming I soldered the connectors on straight. I used FlashFloppy 0.9.28a and the male-male USB cable with a Windows copy of DFUse. You need jumper wires because one of the connections is diagonal. I’ve gone over this a few times already, but flashing the Gotek is basically this process: Open the Gotek Apparently you can get them in “very small.” Standard Canadian quarter for scale.Įventually, everything worked out and I got a board that plugged into the Gotek in all the necessary places. I also ordered a 26-pin header in the wrong pitch. In the interest of time, I ended up just grabbing two male-to-female jumper cables out of my pile and soldering them on. Hopefully some other project needs a very short length of Berg wiring in the future. Unfortunately, I didn’t realize the floppy power connector was on the other side of the board and the cables couldn’t reach, plus it looked bad. Since the Molex connector didn’t fit, I figured I’d just cut one of the very hard-to-find (in my city) floppy Molex-to-Berg adapters I had picked up for the PC88 and solder it on. I’m currently thinking about ways to tile my bathroom with the leftover PCBs. Has a Molex connector with the correct footprint from Digi-Key, is a little teeny tiny bit smaller than v1.2. v1.2: Has a Molex connector, but due to a bad footprint, the holes were too small for the part I ended up using.Also extremely enormous, because I didn’t take the time to route my traces very well after having to rework the board to remove the Molex. v1.1: No power connector, because I somehow got it into my head that the floppy drive would get power from somewhere else, even though I had seen pictures of an existing PC98 adapter that had a Molex connector on the board.v1.0: Cancelled because it had a power connector (d’oh) before it even went to fab.I went through a few revisions of this board - my most boneheaded mistake was omitting the power connector entirely. Note also that I haven’t tried two of the same board in one machine, since I don’t have a dual-drive 26-pin ribbon cable. I ended up routing 6 -> 33 correspondingly, though this might be the cause of a strange problem I seem to be having (more on this later). Pin 2 on the 34-pin is DENSITY from what little I understand of floppy drives, it makes no sense to connect these two. I’m not sure about the “6 -> 2” part of this another diagram I found said that pin 6 on the PC98 is DISK_CHANGE, which is pin 33 on the 3.5” floppy. ![]()
