 Todd .. they are available from the folks at SuperChips for about $20 each
 they work based on timing ..

 An MCU accesses things MUCH faster than an EPROM reader .. hence the problem ..

 If you build a system with an 8051 that reads the EPROM and writes some RAM, you
 can completely bypass the thing ..
