I have a non-working PDT-11/150, which fails self test 7 (console
USART) and when not in test mode, and with autobaud disabled, doesn't
send anything to the console.
I dumped the ROMs (two 82S2708 1Kx8 PROM for LSI-11 code, three 8316E
2Kx8 masked ROM for the 8085 I/O processor, and one 8316E for the 8085
floppy controller), and I've started disassembling the 8085 ROM code
to figure out what the self-test actually does, but it's slow going.
It would be really helpful to have a copy (paper or scan) of the Field
Maintenance Print Set. Does anyone have it?
