Needed: 1 IBM 8" alignment disk.

Before I find the highest building to jump off of, I though I might ask here

I have a Sykes 7150 8" floppy drive (negibus PDP-8I) that I have invested a
half and hour in and have solved *most* of it's problems... It finally talks
to the PDP and I can select tracks, reset, read status, etc... once in a
while read a sector.

I need a single sided 128 byte record alignment floppy.

When I do a read now, the drive stays busy forever looking for the sector I
asked it for. (even if the head is on top of it). Since it was made in 1974
with TTL chips it is only bright enough to sit there and *wait* for the
correct data to come by. An alignment disk would make life a lot easier.

Anyone have one available? Please e-mail.

P.S. The sooner the better.. this thing is eating original IBM software
diskettes from the early '70s
