Can I populate as 2mb but use a 1mb 8372a agnus?
Given how scarce the 8372b agnus is, I'm wondering about a board spin to either:
a) use modern cheaper ram, 1mb, and support 8372 only, -or-
b) use modern cheaper ram, 2mb, and support 8375 directly (no adapter)
But if the board can be populated with 2mb, and use either 8372 or 8375 (via adapter), I'd leave it that way (except possibly cost reducing the ram)
Still wondering about the above?
Also, wondering what the behaviour is if dropping a PAL Agnus into the design? Obviously won't get PAL output over the composite or rf ports etc, but what about via the Denise chip and RGB2HDMI - ends up 50Hz? Wouldn't crystals and other stuff have to be changed too?
I may have goofed and bought a bunch of wrong Agnus chips from Europe
Luckily I have a handful of NTSC Agnus chips coming as well.
