Of course it would, but the DEC STD 092 available is not specified in PANTONE,

That's another problem I think, there isn't any documentation to say
what colors a particular scheme used. I think the PDP8/e is amber and

I tied DEV SEL L for my homebrew LPT to +5 and now F4 runs.
I am curious if the EAE is used with F4. The Language Manual says it
is, but it is only mentioned in one place. There is nothing else to
select using it or not using it. I looked at the sources for various

properly in the 990/189 board, with the 9.3V supplied on the CPU socket.
Thanks,

I don't think it's quite that bad; ISTR something in the manual (BitSavers
