MOTM

Received the first set of 15 MOTM-730 VC Divider production boards.

Every function checks out 100%!

There other 85 CPU boards will arrive ~ 1 week. I will be able next
week to ship the first 15 orders in the backlog for the '730. I will
type up a Owner's Manual this weekend, and I will post
the *binary* firmware files for the 2 PIC processors (one is in a socket
the other soldered into the board). The socketed IC is the main CPU
divide engine, the smaller soldered IC just drives the display. The PICs are
OTP (one-time programmable) so a dedicated programmer is needed
to replace them if one dies and I'm not available for a replacement :)

I do not expect these PICs to die anytime in the next 10 years or so.

The measured power supply current is:

+5V @ 75ma (no outputs driving). Add 4ma/driven (patched) output.
+15V @ 16ma
-15V @ 14ma

The outputs are 0 to +5V square waves for the dividers, and an analog 
'stepped'
sawtooth wave that steps in 4th/octaves/5ths.

All divider outputs can be used simultaneously, as long as your supply can 
handle
it. A MOTM-950 supply can handle 5 '730s, driving ALL the outputs from all 5
as well as a MOTM-650.

SWEET!!!! Paul, I'm not sure where I am in line for one of these but . . . .
when you get ready to send mine make sure you duck when you charge my card
because there may be a huge explosion of critical mass overextended credit!
I don't want you to get hurt! ;-)

Errr....you are actually the *last* MOTM-730 currently on order :)

The first 4 (shipping tomorrow, actually) are going to:

Eric F.
Chris P.
Mark M.
Kenneth T.

No rest for the wicked: Friday is spent mostly on

- finishing 5ea MOTM-940s
- packing up 7 MOTM 2.0 orders
- 1 last kit & assembled tally of the backlog
- ordering some parts and paying a few bills
