I've got a Kaypro 4/84 that arrived today (rescue) and I'd like to install the KayPLUS ROM in it.
The KayPLUS ROM is designed to fit into a 2764 EPROM (the image is 8k). My problem is that the only parts I have laying around are 27256s.
Is there any reason I can't create a "quad" sized image (essentially create a new image file by binary copying the 8k files into a single 32k file) and then install this in the Kaypro? I've done something similar in the past on my C-64, but I added a switch & resistor to bounce between two ROM "images" on the same part.
Barring that, does anyone have some 2764s they want to sell cheap?
tnx!
(fyi, the KayPLUS ROM & docs can be downloaded here: http://www.microcodeconsulting.com/z80/kayplus.htm )
