New user here. Did some homework on Apple slots/drives and I know drive booting is complicated.
I have a IIc with 3.5" UniDisk. ROM is "3" and I successfully booted off the 3.5" media (Appleworks). I only have this one bootable floppy, and zero 5.25 floppies. To remedy, I bought the Floppy Emu kit, with IIc drive switcher. :-)
My #1 Goal is to boot off 5.25 disk images. I'm not able to get this to work in any combination I've tried.
- I can however (1) boot off the "hard disk image", so the hardware is OK.
- I can also boot off "UniDisk Mode" using (2) the standard straight-thru DB19 connector, or (3) the "IIc switcher" when it is in straight-thru mode (which indicates I wired the IIc switcher correctlty)
My Tests to boot off 5.25 Disk Images:
My understanding is this requires "IIc switcher", in "X" mode.
- Plugging Floppy Emu (5.25 mode) directly to the IIc switcher and into the back of the IIc port, select a 5.25"image", and power on... I get the "Apple //c" screen but no other text. Doesn't seem like the OS tried the Emu, and which remains on Track 0.
- Images tried: Archon, Blazing Paddles, Border Zone (both variants), Castle Wolfenstein, Choplifter, Frogger... also The Print Shop, and a few random utility images
It looks like my //c won't even "try" booting an external 5.25 image, which I thought the //c Switcher was meant to resolve?
The one thing I haven't tried is connecting the Floppy Emu directly to the ribbon cable port inside the case. However I understood the //c switcher was created to avoid that scenario right?
