The FirstComputer that TimRiker ever worked on was at [[http://www.penfield.edu/phs/|Penfield High School]] in [[http://www.penfield.org/web/|Penfield, New York]]. From what I've been able to determine it was a HP-2114B model. It used a form of time shared basic, but it was '''not''' a dual cpu model cabinet. It was running a time shared basic environment. Perhaps the "TIME-SHARING EXECUTIVE" mentioned in the [[http://oscar.taurus.com/~jeff/2100/family/family.html|sales brochure]]? There were no "accounts" on the machine. Everyone used the same program storage space. This is unlike any version of HP2000 (ie: HP-TSB) release TimRiker has seen so far.

The FirstComputer that TimRiker ever worked on was at Penfield High School in Penfield, New York. From what I've been able to determine it was a HP-2114B model. It used a form of time shared basic, but it was not a dual cpu model cabinet. It was running a time shared basic environment. Perhaps the "TIME-SHARING EXECUTIVE" mentioned in the sales brochure? There were no "accounts" on the machine. Everyone used the same program storage space. This is unlike any version of HP2000 (ie: HP-TSB) release TimRiker has seen so far.

TimRiker acquired a bunch of old HP hardware including an HP-2116A that he is in process of restoring. Check the Gallery for pictures and updates as work progresses. Adding some notes on HardwareNotes

The system config as best recollected:

  • HP-2114 style cover with 16 bit touch switches. key lock, and preset/run/halt/load/etc touch switches.
  • mounted in a rack mount cabinet
  • 32k of RAM installed split 5/5/3/3 or similar for the 2 CRTs, card reader and teletype
  • ASR-33 teletype with punch tape reader (writer?)

  • 1 text crt terminal
  • 1 "graphics" terminal (honeywell? I remember it had a graphics character set with a toggle button)
  • 2? disk drives. (type? 8" floppy? drum?
  • card reader
  • line printer
  • external tape punch was not connected.

The admin was a Dick Stover who has since passed away.

Here are some useful links:

Hacking HOWTO:

  • install SIMH above and start "hp2100"

  • load the hp basic sources: "LO basic1.abs"

  • jump into basic "GO 100"

  • input a simple program like this one "forever":

    10 DEF FNA(X)=ATN(TAN(ATN(TAN(ATN(TAN(ATN(TAN(ATN(TAN(X))))))))))
    20 DEF FNB(X)=FNA(FNA(FNA(FNA(FNA(FNA(FNA(FNA(FNA(FNA(FNA(X)))))))))))
    30 DEF FNC(X)=FNB(FNB(FNB(FNB(FNB(FNB(FNB(FNB(FNB(FNB(FNB(X)))))))))))
    40 DEF FND(X)=FNC(FNC(FNC(FNC(FNC(FNC(FNC(FNC(FNC(FNC(FNC(X)))))))))))
    50 DEF FNE(X)=FND(FND(FND(FND(FND(FND(FND(FND(FND(FND(FND(X)))))))))))
    60 DEF FNF(X)=FNE(FNE(FNE(FNE(FNE(FNE(FNE(FNE(FNE(FNE(FNE(X)))))))))))
    80 PRINT FNF(1)
    90 END
  • list the program: "LIST"

  • then run it: "RUN"

  • note that on real hardware this silly deeply nested program could take a very long time to finish. On a 1G ppc debian linux box with SIMH 3.3.1-1 it takes about a half hour and then prints 1. :)

  • Here's a more useful program I whipped up that graphs trig functions

    100 REM TRIG BY TIM RIKER <TIM@RIKERS.ORG>
    110 LET X1=-3.2
    120 LET X2=3.2
    130 LET X3=.1
    140 LET Y1=-1.5
    150 LET Y2=1.5
    160 LET Y3=(Y2-Y1)/70
    170 LET X4=(-X1)/X3
    200 FOR X0=0 TO (X2-X1)/X3
    210 LET X=X1+(X3*X0)
    220 LET S0=INT(((SIN(X)-Y1)/Y3)-.5)
    230 LET C0=INT(((COS(X)-Y1)/Y3)-.5)
    240 LET T0=INT(((TAN(X)-Y1)/Y3)-.5)
    250 LET Y0=INT(((0-Y1)/Y3)-.5)
    300 FOR Y=0 TO 70
    310 IF Y=T0 THEN 520
    320 IF Y=S0 THEN 540
    330 IF Y=C0 THEN 560
    340 IF Y=Y0 THEN 580
    350 IF X0=X4 THEN 600
    500 PRINT " ";
    510 GOTO 700
    520 PRINT "T";
    530 GOTO 700
    540 PRINT "S";
    550 GOTO 700
    560 PRINT "C";
    570 GOTO 700
    580 PRINT "X";
    590 GOTO 700
    600 PRINT "Y";
    700 NEXT Y
    710 PRINT ""
    720 NEXT X0
    999 END
