I updated the project to include optional OS/8 support. I won't say I've tested it extensively, but it does seem to be working as expected in SimH, anyways. I updated the README to reflect the additions.
... I tried it out: I dowloaded the hp35only.pal-source, because it needs only 4K of memory, kermited it to my PDP8/E and succeeded assembling with PAL8 without modifying the PALBERT-code. After starting it worked well. :-) As I'm always looking for 4K-applications for our older machines, I downloaded the .BN to our classic-8 and started it. It gave "strange" output. :-( A look in the source showd some BSWs, an operation that doesn't exist on pre PDP8/E machines. I replaced the BSWs with "JMS BSWEMU", a short subroutine to perform the byte-swap and now the hp35 runs on the classic-8 with 4K of memory too. I also had to replace the MQLs with CLAs. Next step is to modify the output, to run it with a teletype...
