[Coco] Harddrive Specialists floppy controller

[Kip Koon]

Hi Art,
Thank you for that information.  I have the Harddrive Specialist Floppy Controller also.  Mine is working great with the HDB-DOS DW3 Coco 3 rom in it.  I have squirrelled this vital piece of information about this controller away for later use as well.  I appreciate your efforts over the years.  Thank you very much.

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.
