Spice 2g6 is a circuit simulator. This version requires a 386 AND 387 math
coprocessor. It does not work on D.J.Delorie's 387 emulator. However because
it uses D.J.Delorie's go32 dos extender, it can use up to 128 Mega bytes of
RAM, or do swapping.
To execute, type:
go32 spice
To run it independently, concatenate go32.exe with spice, e.g.
copy /b go32.exe+spice spice.exe
Supported Wares:
* Up to 128M of extended (not expanded) memory
* Up to 128M of disk space used for swapping
* SuperVGA 256-color mode up to 1024x768
(needs DJ Delorie's drivers)
* 80387
* XMS & VDISK memory allocation strategies
Unsupported:
* V86 programs, like QEMM, 386MAX, DesqView, Windows/386, etc.
This is spice 2g6 as originally written in fortran by University of California
Berkeley. I translated it to C using f2c distributed by Free Software
Foundation but originally from AT&T. The fortran to C conversion is done using
a 386bsd OS, the f2c libraries and spice sources are compile,archived and
sorted using a gcc-1.39 running on a 386bsd.
The changes major made are only in unix.c to enable it to use time() instead
of times() for measuring time.
