I've just recently read a copy of an article (being passed around on floppy)
titled "Adding a Third and Fourth Floppy Disk" by Eric D. Black, dated April
1986.  It describes building the small amount of circuitry needed for adding
external 3.5" drives to the amiga.

I have a few questions:

1) Eric, are you still out there usenet somewhere?  If so, please send me
   your email address.

2) Eric used Toshiba drives (model FDD-4403AQK-02), from Halted Specialties
   in Sunnyvale, for $99.  Can somebody send me Halted's address and phone.
   Do you know whether they still carry the drives?  OR are there any other
   places selling these drives?

3) Are there other drives that are plug-compatible?  (and don't say NEC
   model FD1035; the Toshiba was much quieter, and I rather like that
   feature).

4) If I were to lay out a PC board for this circuit, would anyone else be
   interested in having one?  It has about 3 TTL chips and a few transistors
   and resistors; nothing major.  The main advantage of a PC board is that
   it will free you from hand-wiring the DB-23 and 34-pin drive connectors.

I will summarize and post the results.
