I was looking for the 13 sector P5 PROM binary
so I could insert it into a copy of the IIe ROM
at location C600-C6FF. Hoped that if I did that
I could boot an NIB image of DOS 3.2

Yes, they are the images I was looking to write to
a real disk, if I could find a program that can write
a NIB to disk. In AppleWIN you can boot the DOS 3.3
Master disk image and run BOOT13, then switch images
and hit "6" and enter. The "std" boots to a ">" prompt
and I didn't try the "pls" one. Thought I had put aside
a controller that I believed had the 13 sector PROMs
but I can't remember where and I'm not finding it now.
If I can locate this card I'll write out the P5 PROM
and post it to my web site.
