Procedure to customize HP Paper Tape BASIC

This procedure will be carried out in the SimH hp2100 emulator. HP Paper Tape BASIC needs to be configured for your console device, paper tape reader and (optionally) your paper tape punch. Once you've generated the configured NEWBASIC.ABS file, you can punch that with whichever physical paper tape punch you happen to have, on your favorite OS.

1. Grab the HPBASIC.ABS and PREPARE.ABS files, which are in Absolute Binary format.
2. Set up a config file for SimH, to match the hardware setup on your system. My 2108A config is:

       ; Simulation configuration for 2108A paper tape system
       ; Configure CPU as HP 2108A (1000-m) with 32 pages of memory
       set CPU 1000-M,32K
       set CPU ROMS=PTR;DPC
       set CPU idle
       ; Setup for running paper tape BASIC
       set LPT disabled
       set TBG disabled
       set DPD disabled
       set DPC disabled
       set DQD disabled
       set DQC disabled
       set DRD disabled
       set DRC disabled
       set MSD disabled
       set MSC disabled
       set DS disabled
       set BACI disabled
       set MPX disabled
       set PIF disabled
       set MUXL disabled
       set MUX disabled
       set MUXC disabled
       set DA disabled
   
       set TTY SC=15,enabled	; 12531D on SC 15, 2645A terminal
       set PTR SC=16,enabled	; 12597A on SC 16, 2748B reader
       set PTP SC=17,enabled	; 12597A on SC 17, virtual punch
   

3. run the hp2100 emulator and enter the Select Codes (SC) for your console, paper tape reader and paper tape punch devices:

hp2100 2108A.sim
sim> ATTACH PTR PREPARE.ABS
sim> BOOT PTR

    Programmed halt, T: 102077 (HLT 77), P: 77712 (JMP 77700)

sim> BOOT PTR

    Programmed halt, T: 102077 (HLT 77), P: 77712 (JMP 77700)

sim> DEPOSIT S 15	(15 is the SC of your console device)
sim> DEPOSIT P 2
sim> ATTACH -N PTP NEWBASIC.ABS
sim> RUN

    PHOTO READER I/O ADDRESS? 16

    Programmed halt, T: 102077 (HLT 77), P: 16562 (JMP 16547)

sim> DETACH PTP
