go75c


HP75C hardware emulator.

  • automatic save state
  • speed from 1 up to 10 (with a fast device)
  • on board ram at 24K
  • internal MATH rom, IO rom, VC rom and ODS rom.
  • card reader supported with card capacity upto 24K (no more multi card programs)
  • use lif based raws files (lif-header + datas see ftp://ftp.hpmuseum.org/lif), lif disk images not usable.
  • .b75, .l75 and .t75 can be converted into card files (.crd) and loaded
  • no HPIL emulated at all (actually)

To use at best this emulator you SHOULD have a minimum knowledge of the original system.



Hints : call config screen with a touch on left part of LCD emulated display
  • MATH, IO, VC, ... roms are plugged in with the top buttons when system is shut off (SHIFT ATTN)
  • save a file from the emulator, just use 'COPY "name" TO CARD' with name a named file of the system, will create a card named name.crd
  • 'import/export' to get them at 'go75c/card'
  • put BASIC/LEX/TEXT file in 'go75c/basics|lexs|texts' and convert them to card
  • on kitkat device, import/export directory is now /Android/data/o2s.emul.hp75/files/... instead of /go75/... on the sdcard. 
  • select a card by touching the lower right 'strange' button ...
  • load a card with 'COPY CARD TO "name"' press RTN when asked for.

Thanks go to Paul Berger for some rom dumps.

Version 1.0

  • first release, no sound
