Thanks Joe for the response! I have learned a little
more since I posted that message. After researching
possible replacements for the AM6012PC I concluded
that Analog Device's DAC312 might be a drop in
replacement at a cost of around $6.50 to $8.00 per
chip. The DAC312 is a currently manufactured chip.
Then I did a web search for "DAC312" and I got the
arcade schematics/data sheets page on www.spies.com as
a hit... Doh!

http://www.spies.com/arcade/schematics/DataSheets/dac312.pdf

Per Spies it also appears that a drop in replacement
for the MC3410 is Analog Device's AD561.

Has anyone successfully used the either the DAC312 or
AD561 on a Tempest board?

Thanks,
Noel
