Anybody familar with a "Technical magic
8S" card? I found several of
them in a DEC system. They're double width cards and have eight AMI S1602P
LSI ICs on them. Chip Directory says that the 1602s are UARTs.
Presunmmbly it's an 8 channel serial card (the name '8S' would also
suggest this).
It'll either be an octal DLV11 (Systime certainly made a Unibus octal
DL11) or an 8 channel version of the DZV11. The former would have all 8
ports at distinct addresses, the latter is what DEC call a 'multiplexer'
and has all 8 ports sharing a relatively small number of addresses.
