Heard of it??
When I closed my office, I got rid of several hundred boxes, manuals, and
defective boards.
It connects between an XT floppy controller and drive. You need to use
both the edge connector and the dual row header, just like with a CP
Option board. Some drives work better than others. Tandons worked OK,
Teacs were harder to make work. There were also some boards that were
defective.
Vertex commissioned one fellow to design and build the hardware. He felt
cheated.
They commisioned another fellow to write the low level sector
routines. He felt cheated.
They commissioned me to write the high level routines. I felt cheated. At
the time that they went under, they owed me enough money (for that and
when they distributed Xeno-Copy) that I could have bought a house outright
in silicon valley.
The software that I wrote handled reading and writing Apple-DOS, Apple
CP/M, PRO-DOS, and Apple P-system.
I'll try to locate a copy and put a disk in one of your boxes.
