I just did a search for pdp 8A prom images and could not find
any. I'm sure I just looked in all of the wrong places
Any help, Looking for 158a2 and 159a2

I'm hoping to get an 8/a next week; if I do, and if they're
socketed, I'll read them in for you.

I look forward to any PROM dumps (and should probably check my own
boards to see what I have), but there are 2-3 common sets documented
in the literature that cover various device combinations (RX8E, RL8A,
RK8E, PTR, DECtape, etc) ISTR there's only 4 bootstraps per PROM set,
so if you have a complex setup, it's not unlikely you may want to boot

?I'm hoping to get an 8/a next week; if I do, and if they're socketed, I'll
read them in for you. from two different devices that don't happen to be
in the same set.
I'd quote chapter and verse on which part numbers contain
which
bootstraps, but you'll find the definitive answers in the Small
Computer Handbook (under KM8AA) and possibly in a table in the margins
of the printset. If you don't have an RL8A, it's likely that the
older PROM set will be exactly what you need. If you do want to boot
an RL01 and you have other system devices, I'd say it's likely that
you will want two sets of PROMs on hand.

I should be able to find them. Their contents are documented in the PDP8A
users manual starting at 6-58
The three variants that I see are
87A2, 88A2 PTP,RK8E,TC08,RF08,TA8E
138A2, 159A2 PTP,RK8E,RX8E,RF08,TA8E
and
465A2, 469A2 TA8E replaced by RL8A
documented in the RL8A manual, but bootstrap
not listed

Thanks Al,
This does help a lot. I did find the 465A2 and 469A2
But did not know what they where all about. Of
coarse I would not have looked in the RL8-A
manual in a million years.
