abc80 \- An X windows based emulator of a Luxor ABC80
.B abc80 [-b] [-d] [-v] [hex-files]
\fIabc80\fR is an emulator of a Luxor ABC80 under X-windows. The
program is built around a Z80 emulator by David Gingold <email@example.com>
and Alec Wolman <firstname.lastname@example.org> who wrote it to use in an emulator for
Beware that the program runs at maximum CPU at all times, it never
blocks for IO except when reading and writing files.
The program emulates most of the functionality in the ABC80 including
the real time clock. The sound chip, and most of the PIO functions
(like the casette-tape inteface) are not emulated though. There is
however a new device called UNX: which get installed as the default
device. This allows reading and writing of files to the UNIX
filesystem. The list of error code explanations is also emulated :-)
If the program crashes, your X-server will probably be left with auto-repeat
turned off. This is fixed with the command: "xset r". It might be a good idea
to define a shell alias as "abc80; xset r".
\fIabc80\fP options can appear in any order.
Makes the program print out its current version and then exiting.
Stops the emulator from reading in the "device drivers" in abcdev.hex
Stops the emulator from reading the BASIC interpretor PROMs in the file
abcprom. This will leave you with a bare ABC80 "hardware"
If any files are given on the command line, the emulator will expect these
files to be Intel-hex coded and read them into memory before starting.
.SH "BUGS :\-)"
The list of error code explanations are "emulated" by a bitmap in a window
which can be pulled out from under the "main" window. This error-window does
not behave correctly (it doesn't stay stacked just under the main window) if
windows are moved around in the screen stacking order (brought into the
foreground or pushed into the background).
