Update: The first thing I tried was removing and reseating the boot ROMs
(465A2/469A2), since they did not use good machine-tooled sockets.
Now the boot loader performs normally, no incorrect locations, and OS/8
boots from Drive 0 whether using the boot key or manual start at 0001.
Great!

As previously posted, reseating the boot ROMs in their sockets cured the
corrupted boot loader issue. Got lucky there :)
In my system there are two RL02 drives. I will call them "Top" and "Bottom"
here, after their physical locations.
I put the OS/8 pack that had been acting strangely in the

Correct me if I'm wrong, but if I got this right, you wrote the boot

Need the following items for an ex-Bell System Model 15 TTY:
Keycaps - F K L C V B N with punctuation symbols, rather than fractions. I
have a set with fractions to sell or swap.
Keycaps - CARR RET and NULL (blank). These are missing.
Platen crank - This is missing.
Think that's all for

Note that some bipolar PROMs suffer from fuse regrowth, where bits
that have been programmed gradually revert to an unprogrammed state.
This was a big problem with NiCr fuses. Later
