RE: Eprom rom dump issue
When in doubt, examine the image with a hex editor. If the first eight bytes are "3BDDDDED", the Stand Alone Module ID or "IRAM Identifer" then the image is an IRAM, otherwise it's a ROM.

Of interest is the Finance ROM, which has the IRAM Identifier.

From the checksum bytes I see that you've version 6.2A of the AMP ROM set. I'm missing ROM02 from that set. If you have it could you please post an image of the EPROM?

Thanks,
Dave
