Steve,
To me, it looks like /WE and /OE will be active together, not usually a good
thing.

Hi all,

Sorry for the delay. I looked at what I'd drawn and realized it was a little
messy, so I've re-drawn it. Please excuse my sloppy drawing skills. I need
to learn one of the layout tools available and make a proper one.

So, for those interested, here is my hand-drawn CBM-II 24K RAM/EPROM
cartridge
schematic:

You can see a picture of it on my CBM-II web page:

Thanks again to Ernie Chorny for lending me the cartridge!... Ernie, I
promise to get it back to you soon ;-)

Steve
