Re: Major Havoc fluke 9010a rom testing

I believe you are correct about FFFF being the range of the 6502, which
makes it all the more odd that Quarter Arcade has such a high address
listed.

http://tech.quarterarcade.com/tech/VM.aspx?g=1669&set=mhavoc

Probably just a mistake.

The Memory map on the MH Schematics show the Range, and for the Rom/s in
question the range should be 2000-3FFF but you have to page between the two
somehow, and that's were I'm failing.

It looks like the address 1740 is used to page between the two roms, but
since I've never had to do that, I'm unable to verify the roms.

The Rom at 8000-BFFF and C000-FFFF are not paged and I can check just fine.
Mind you that this is all on the Alpha processor. Not the Gamma I haven't
gotten that far as of yet.
