[Coco] Harddrive Specialists floppy controller

[Arthur Flexser]

Here's an exchange on the list about that from way back in 2003 that I
filed away:

------------------------------------------------------------------------------------------

Here you go, Mark:

The ABC jumper selects between ROM sockets A (24 pin) and B (28
pin)--AB=socket A; BC=socket B.

The other 2 jumpers affect the 28-pin socket B, which may be set to accept
either a 28-pin ROM or a 24-pin one (by leaving pins 1, 2, 27, and 28 with
nothing plugged into them).  The DEFGH jumper handles that:  Connect EF
and GH for 28 pin operation, DE and FG for 24.  Under 28-pin operation,
IJK selects ROM capacity: IJ for a 2764, JK for a 27128.
