I also have an LSI ADM3A (built from a KIT .. anybody remember
those?). Last summer, I was thinking about using it again after
it sat in the closet for 5 years. However, no lower case :-(
(Unix don't like no stinkin' lower case!) I wrote LSI a letter
inquiring about the LC rom. They wrote back (are you ready for
this) that they'd sell me one for $50 plus shipping. I about
fell down the stairs on that one... You can occasionally buy
WHOLE ADM3s at about this price when property surplus has it's
disposal auctions.
I think what I might do is to have my students design the ROM
in class next semester for me (nice to have a pool of slave
labor --- JUST KIDDING!)...
