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! ;-)

Subject: [motm] MOTM-730 production boards are ∗ALIVE∗!
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.
