HP-21MX bootstrapping?

ok, been meaning to actually run something more than the little assembly test apps on my HPs. How do folks bootstrap systems? I've got 2 working HPs (HP-2108A and HP-2112A) and HS-TERMINAL (ie HP-12531B) and I can get lights to light up with a 2400 baud connection and this snippit running: 0001* set to TTY I/O number 0002 00011 SC EQU 11B 0004 00040 ORG 40B 0005 00040 106700 LOOP CLC 0 Turn off I/O interrupt system 0006 00041 060051 LDA TTYIO Load A-register with control word 0007 00042 102611 OTA SC Output control word 0008 00043 103711 STC SC,C Set control, clear flag 0009 00044 102311 WAIT SFS SC Wait for flag 0010 00045 024044 JMP WAIT Loop till ready 0011 00046 106511 LIB SC Input data word 0012 00047 106601 OTB 1 Output data word to switch register 0013 00050 024040 JMP LOOP Next char 0014 00051 160000 TTYIO OCT 160000 TTY input and print control word LOOP 000040 01/0005 -- 01/0013 SC 000011 01/0002 -- 01/0007 01/0008 01/0009 01/0011 TTYIO 000051 01/0014 -- 01/0006 WAIT 000044 01/0009 -- 01/0010 4 symbols 14 lines assembled, 10 words generated 0 errors, 0 warnings (also online as http://rikers.org/hp2100/ttyin.lst) so what's next? Is there a tape loader for use over a 12531? Also, I'm using a modified version of the perl assembler. I'd like to actually use the native HP assembler under SIMH. The HP / CHM agreement should allow for at least this much bootstrap information to be shared. I'm happy to put up bootstrap instructions and tape images if someone can provide them. I don't have any other peripherals tested out yet. Not sure why my real paper tape reader is not working yet. My paper tape punch is a long ways I've got tape images that work in SIMH like the HP-Basic. Just want to see these work on real hardware by loading them over a serial line. There are quite a few HP collectors out there. How do you folks boot up your hardware? ok, I could get an HP-7970 9 track, but I don't have that either. It would seem useful to be able to bootstrap any given tape over serial. I know it's only 2400 baud, but just about every HP collector should have the needed hardware. :) Help me out! PS: Some nice list owner promised to get me a CD full of stuff to get started, but alas, I'm afraid my process is never getting scheduled. Perhaps I need more of a real-time OS. -- Tim Riker - http://Rikers.org/ - TimR at Debian.org Embedded Linux Technologist - http://eLinux.org/ BZFlag maintainer - http://BZFlag.org/ - for fun!
