Re: Detecting ROM

[Roy and/or Janet Miller <millers@inetnebr.com>]

Use a ProDOS 8 disk (disk utilities would work fine) and then note the message
on the screen. If it doesn't say ROM 01 or ROM 03, you have 00, and that's what
you'll need to say too. If it were a Woz, then you might want to have it as a
collector's item, but it you want to use it you could well have some other
difficulties, since there was another chip (something to do with the video as I
recall) that needed to be replaces as well as the ROM.

Hope this helps.
