Hello, This is a plea to any CoCo 3 users who have wanted to expand
their configuration only to find the expansion medium, the `Multipak'
bus interface scheme marketed buy RS discontinued three years ago.

I recently purchased the Burke & Burke HD interface card and software,
a controller for MFM type disks and an ST251 Hard drive.  After
migrating from the MS-DOS workd, (and a hard disk), I didn't want
to jump back 10 years into the floppy disk days when I was working with
CPM.

I have heard about a Multipak called the `Export' but I have been unable
to find it.  Instead, I am about to build my own Multipak, but I'm not
sure of the addressing scheme or distribution of interrupts.

If anyone is familiar with the multipak wiring and can send me the
details on how the slots differ, I would really appreciate it and
begin to build one.

Thanks in advance,

  Jeff Fall Eastman Kodak Company, 716-726-0286
