Apple II ROM's and Adaptor - Now available!

["Henry" <apl2research(.a.t.)comcast.net>]

Hello everyone.
I've seem people ask from time to time where they could purchase II/+ ROM's. 
The main issue is you need an adaptor to convert 2316 (9316) ROM's to the 
more modern 27-series EPROM's or you'll need to find original Apple ROM's. 
Some Arcade machines I've been working on have had the same issue and also 
use the older ROM's which are no longer available or hard to find.


While doing a little research I found out how to create just such an Adaptor 
and will soon be offering it for sale in the Store along with all the Apple 
II/+ ROM's.  If anyone needs one right away just email.

I like it when projects from other genres cross over! ;-)
