switching between EPROMS

[Warren Crowther]

Hello All,

quick question:

has anyone made a device that you can plugs lots of EPROMs into, plug into
your car ECU, and switch between them with a switch??

I want to make one for only 2 EPROMs, and was thinking of using a simple
switch to switch the chip enable between the EPROMs.  Will this work?? or
will the time gap when neither of the EPROMs are enabled be enough to
confuse the micro, and go into some unknown state?  

I could use latches and some simple logic chips to get around this I guess.

Any recommendations??

Warren
