SI made lots of disk products for DECs. At one point I had a somewhat
trashed Diablo drive for a PDP-8/E (RKmumble), with an SI interface board
and power supply. I still have the power unit, if anyone os interested,
but the rest is long gone.
SI also made a neato disk cache for the VAX-11/780. Neato, as it had an
LED bar graph for the hit rate! No stinkin' ten LED doodad this - this
graph had *many* LEDs, because you never know when you will need to know
just how precise your cache is...

Do you remember what kind? Shame on you for noting the modern Harris but
not the classic RCA...

Generally broadcast transmitters and computers don't mix.
