done. Also added a converted bbltelprinter.asm lst and abs oh, and
uploaded the 12992K (paper tape BBL) source, list and tape image too.

I believe the ABS format, with new BBLs for new
devices, continued to be used with
the later 2100 systems but others can comment on that better than I can.
Just a brain fart. I was thinking ABS and seeing BBL and went "huh?" I
got it now. :)
I will hazard a guess that if an HP serial-line loader
for the 2100 shows
up it may look a lot like what I'm describing in modifying the old teleprinter
loader.
the BACI card is different to code to, and Jay says that's what the 264x
loader uses, not looked at that yet.
Didn't you have a 2116B with a broken aluminum
frame, or was that someone else?
Yes to the frame, but it's a 2116A. I don't know anyone else with an A.
Mine is still having power supply issues, I've just not gotten back to
it. If anyone else has an HP-2116A, I wanna hear from you! Still looking
for Volume2 of the docs to cover the different core layout on this machine.
By the way.... The issue with the paper-tape loader was just a timing
issue. There apparently is no flow control on my serial line, so I had
to slow down the upload. I've just loaded HP-Basic (hpbasic1.abs) over
the serial line using the paper-tape IBL. woot! First I've gotten basic
up and running on this HP-2112A. :)
The issue I was seeing with 0x0A was just the default Linux flushing.
adding a fflush() call in my test app got me past that. :)
Thanx for the help! I'll post the steps online someplace soon.
