I dug the old family Apple IIc out of storage and picked up a Floppy Emu. I inspected the board and drive and cleaned it up. Booted fine. Next I upgraded the ROM (including W1/W2 mods) from v255 to v4 so that I could read and boot from the FEMU. Also installed the BMOW Internal/External switcher for the IIc. All seemed well.
I can now boot from the FEMU or the internal IIc drive. The computer can read disks from either drive with no problem. YAY! Unfortunately, writing is another story. It seems as though disk writes from saving files isn't possible. Copying doesn't work, nor does formatting. Instead I get various disk write error, depending on the program used.
I'd appreciate any insight into the issue, including even what to trouble shoot next. I could reverse the ROM upgrade to see if the new ROM is the culprit, or start examining circuitry in either the computer or the disk drive. Thanks for your help.
