Well, I'm a little late in reporting, but here's what I found out:

Kenmore Technologies is still in business, and is still producing the clock.
Their price is $99.95.  Chris is buying bare boards from them (he could
simply copy the board design but he's "not in the business of ripping off
people's intellectual property"), and populating the boards himself.  He's
offering the finished product for $79.95, including shipping.

The board plugs into the Z-80's socket, and then the Z-80 plugs into the
board.  For machines which lacke the clearance above the CPU socket for the
addtional board, there is a version that connects with a ribbon cable,
allowing the board to be sited elsewhere.  One needs to be careful of how
the cable is routed, avoiding RF noise from switching power supplies, etc
(the only failed installation Chris ever heard of was with an Altos whose
switcher drove the CPU nuts).  The device (a National 58167) appears at I/O
address 0xE0 (0E0h for you old-timers :-), and can be moved to a different
address with trace cuts and jumpers.

Checks should be written to Chris McEwen, and sent to him at:

       P.O. Box 12
       South Plainfield, NJ 07080-0012
       908-755-6186

The above phone number is covered by an answering machine, whereas the one
Jay gave earlier may not be.  You're more likely to reach Chris directly in
the evening, by the way.  Around 8pm seems to work.

                               -Jim.
