KEGS v0.35 released

[kentd@cup.hp.com (Kent Dickey)]

I'd like to announce the release of KEGS v0.35, an Apple //gs emulator.

New with this version--a portable, C-only 65816 interpreter!  With only a little
work, KEGS can be ported to other Unix workstations.  With a bit more work,
KEGS could run on Linux.  I haven't tried doing any ports yet.
If anyone is interested in trying a port, let me know.

The portable interpreter is about 2X slower than the assembly interpreter.
But it's still a lot faster than XGS--I'd gues 2-3X faster, but I haven't
tried XGS recently.  And KEGS is a lot more accurate than XGS.

Also, KEGS v0.35 is 20% faster than v0.32, and now includes some limited
serial port support.  You can "telnet" to the emulated //gs.  See the included
README file.

KEGS is available at:

The change log for KEGS since v0.32:

Changes in KEGS v0.35 since v0.34

- engine_c.c fully implemented--KEGS now has a version completely written
   in C, and now portable to other Unix machines.
- KEGS got another 5% faster with more tweaks to the asm dispatch loop.

Changes in KEGS v0.34 since v0.33

- KEGS is 10-15% faster due to finally implementing a planned recoding
   of the dispatch loop.

Changes in KEGS v0.33 since v0.32

- Fixed bug in engine_s.s that prevented compiling on pre-10.20 systems.
- ADB mouse interrupts work now.  Fixed "bug" where GSHK would think
   mouse button was depressed at startup. (GS/OS is looking at mouse
   button 1 status, which accidentally was reading as down).
- ADB emulation of read char_sets and read_kbd_layouts now matches a real
   //gs.
- optimization to allow dereferencing page_info[] even if BANK_IO is set,
   to get a small speed improvement in engines_s:dispatch().
- SCC logs are 'Z' at the disas prompt.
- Tool decoded is 'T' at the disas prompt.
- SCC changes to support slot 1 == port 6501 and slot 2 == port 6502,
   with limited interrupt support.  Most serial tasks won't work still,
   but some do.  PR#1/2 and IN#1/2 work fine.  getty under GNO doesn't.
- -audio [0/1] forces audio off/on.  This just stops the sound playing--
   internally all Ensoniq interrupts/etc are fully emulated.  If display
   is not using shared memory (i.e., it's remote), audio defaults to off.
   (but can be forced on with -audio 1).
- -display {foo} sends X display to {foo}.
