I did decide to just send the ESB kits out as parts instead of assembled.
Getting smarter in my old age. ;-)

I think the SW/MH->WG board is a really good idea. Just be a matter of
getting it produced cheap enough so people can buy it. It might be low
volume though...

[Nightmare]
I think that Nightmare will end up being 1 PCB that plugs into the 68000
socket. If I can get the Nighmare data into a format that the OKI ADPCM
chip likes that'll be cool. I'll put all the counters, decode, and
spinner-knob circuitry into a Lattice PLD. There's a little analog in
there too, but not much. Should make for a tidy board. Surface mount
could be pretty cool 'cause it'd be so small, but I think I need to do
through-hole to be practical. I'll probably just do a run of 25. The cost
will be higher, but I doubt I'd be able to get rid of more than that...

I'll let you in on the rest of my pet projects:

1)
68000 based Vector-game board. Output compatible with WG Vector monitors.
Support for trackball(or spinner) and 16 buttons. Color. Modern parts.
Full programming information. Small, cheap, comes with 1 game (less than
$100 fully loaded). Hopefully other people will code for it! Comes with
libraries, C compiler, etc.

2)
Raster Monitor tester. Done, needs a PCB. Maybe revisit the code one more
time...

3)
Track-man. Single chip that when connected to joystick(s) emulates a
trackball or spinner knob with both quadrature and dir/clk outputs. (For
those people that really want multi-games without having a
trackball/spinner control panel.) Also will take clk/dir input and output
quadrature and vice-versa. (Just a "Small Matter Of Programming"... ;-)

4)
Figure out this Fluke 9010A Unit Under Test microprocessor troubleshooter.

5)
Figure out, collect, and assemble the parts for the Tek 1240 logic analyzer.

6)
Vectrex clone PCB with built-in multicart and WG-output. (This was
originally a function of #1, but they're a little too different to do
properly...)

That's the big ones. ;-) Finish "Moon Lander" etc...

Now you should be *really* worried... I do actually get things completed
from time-to-time though... *laugh*

I still might send your box. Depends on if I find Pong tonight. If
nothing else I really need the extra space in the garage. (I still have
about 100 square feet of Atari stuff stacked chest-high from Travis and I
buying all of Dave Wiebenson's old stuff...)
