I am looking for a set of boot proms that would enable me to boot from the RL01 that is

That is, if such a boot prom actually exists.....
And as a side note : why is the 8/A so unloved ?
Big RL01 disk, 128k memory, fpp processor, all in one case. Try that with another -8 !

I've uploaded the two bootroms you need to boot a RL01 on a PDP-8A using a KM8
(M8317). You'll need to burn the images into 82s126 chips. I've also uploaded the
corresponding level 8A schmatics/manuals which have this level of ROM described (IIRC on
the third page of the KM8 portion of the schematics).
You can pick up the images and manual by:
ftp bickleywest.com
user: anonymous
pswd: (email address)
cd pdp8a_bootrom
