OK, so 'recent' assembly has already been done - not surprising.
We had a new assembler for the 9830 and figured it would be minor to (back-)convert it for the 21xx. It hasn't been as straightforward as anticipated however, due to the vagaries of the original HP assembler syntax.

There are no binaries in the directory with the BASIC source, however it appears the Moffat archive is now on bitsavers and there appears to be a binary there for a version of the interpreter and PBS, along with lots of other early stuff to investigate.

I had found the Moffat pages years ago when they were at his own site, before they were on bitsavers, but as I recall the binaries did not download transparently at that time, that's why I was looking at assembling the source at this time.

(Your) source for BASIC is in the 'pdf' section of bitsavers, beside the hardware manuals:

while the Moffat stuff with binaries is over in the 'software' section:

I don't know what the story is with the Moffat stuff however, a lot of the file links are dead.
Perhaps Al can comment.
