Nice picture, thank you !
By reading the references, I already know what circuits they are, but I'm not a sperman, I don't even trust my mother in this cas, so I rush to :
http://www.datasheetcatalog.com/Go there, and type : S23128B or AM92128BCP
Mmmm.... this is tricky, doesn't work...
Thuis is because they are specific circuits for E-Mu.
Okay, I know its 128K memory, normally replaceable by 27128.
Can you plesae take a pic wich is more general, on wich I can see the static rams ?
There was a machine from ALESIS wich was programming eproms for Simmons, E-Mu, etc...
TIA
