I was contacted off-list by a guy who said.... "I wrote the software in the EPROM on the MMD-2 and did some PC design work for E&L Instruments way back in the 70's, so found your site really interesting. Would love to find out if anyone actually remembers those." Apparently he didn't join the list, but if someone here is keen on talking to the guy about the MMD-2 and related stuff, contact me off-list and I'll pass on his email address. Jay West
