Anyone tried hooking up a gotek to a UNIX PC (3b1)? I'm going to mess around with this at some point. I still don't fully understand the MO (motor enable) jumper on the gotek, do I want this jumpered for 3b1?

JA & S0 | B | Yes | "Ready, ROM error" |

Got the gotek working with FlashFloppy!
David even provides a fully loaded HD to get you started: http://www.pdp8online.com/3b1/demos.shtml
Do you know if a 3B1 disk image would work?
'LD_LIBRARY_PATH=../libdisk ./disk-analyse -v 01.imd 01.hfe'
If you use the FlashFloppy firmware, there is no difference between 720 and 1.44 Goteks; they are identical from a hardware point of view.First, I commend you for getting it to work. As I mentioned in my post, I couldn't get it to work under DOS 6.22 and ROM 1.43.
What size was your GoTek drive 720 or 1.44 Floppy?
