If it's like the other Atari stuff the DAC08 (MC1408) will handle
scaling as well as color intensity. Do you gets color output OK?

If you're still stuck I can get you all of these. $45 for the above

If you want to order separates (and maybe say some $$$ over my price):
Hamilton Hallmark has the MC1495P
AM6012's are trickier. Don't know where to fine originals for any
reasonable amount...
DAC08CN's cross to MC1408's (8 bit) should be able to get from JDR.
Quad Analog Switch should cross to a DG201. Should be able to get from
JDR.
