Jess,

Well, when I was looking for an EPROM emulator, I trawled around and finally bought a NoROM.

It worked so well and had such excellent support directly targetted at the 8051 that it was hard to resist.

Eriks suggestion is fine for folks who have plenty cash - as I said in my NoROM review, when combined with the NoICE debugger, the unit gives great debug capability (across many older micros) for a very reasonable price.

Sorry, mine is not for sale!

Cheers,
Derek.
