Someone threw all the files at me years ago, and it's a giant mess. Assembly source, I could hack some perl together to process into a form that a modern assembler could chew on. It wouldn't be that hard to pull the Forth interpreter out of Gorf and hope that its opcodes match whatever was...

Most of it is in Forth -- it's intended for Astrocade since those games were also primarily written in Forth.

The T11 is basically a hacked down PDP11 on a chip. Keep meaning to ask some of the DEC old timers at work if they remember the T11, but that was probably before their time.

That probably wouldn't be very difficult... ...particularly if starting from commented Atari source code so you don't need to figure out all of the memory addresses / and reverse engineer the subroutines...

Looks like it's intended to run on Atari System 2 hardware. It'd be worth hacking the ROM names and trying to get it to run with one of the existing MAME drivers.

If you unwind all of the various MAME macros, you should be able to parse out the actual mame drivers to make a .INI for any driver.

Upper left is a Galaga video board, but missing most of the expensive parts. Upper right feels like part of a Moon Patrol. Lower right looks like part of a bootleg Birdie King. Lower left look familiar, but I can't place it -- video board for American Speedway, maybe... Would be a lot easier...

Nice work... Far easier to use than the text-based tools I wrote for linux :)

You missed the point, clown. Paying $900 to ship a cabinet doesn't make a cabinet worth $900 more. ...but thanks for putting your (lack of) character on display for all to see.

Example: You paying $900 to ship an empty cab across the country instead of hooking up someone who's local.

It wouldn't be saving high scores without a kit.

Who's not going to recognize Quantum?

The only difference in the "hardware" is supporting 16 2708s instead of just 8. It'd require a complete teardown of the code to make the code relocatable so it could be reassembled without the Invinco stuff to fit in 8k.

Got it down to 17 bytes... I don't think I can get it much tighter :)

It's based on the 16x2708 set, so no, it won't work on 8x2708 boards. ...but you can restrap the boards for 2716s easily and run it as an 8x2716 ROM set... ...or just get plugin for the 6502 that eliminates the ROM on the main board.

Hack complete (works in MAME at least). As it turns out, it only required changing 25 bytes in ROM "271b.u33"

Yep... If you google "Jungle Boy" you'll get the pinouts -- basically converted the .156" power header into more edge connector fingers.

Bizarrely, there's actually screen "rotate" logic built into the code, that mangles logical addresses in to screen addresses -- also handles cocktail flip. (Unflipped) Head On 2 runs with $00, while Invinco and the start menu run with $03.

Should be relatively trivial to just take the "switching" part out of the ROMs. The 2 games are pretty well segregated in the ROM set, with HO2 in the low half and Invinco up top.

Guess that might explain his urgency in wanting to get it done. Did some quick patches over coffee on the 27th, but the version of MAME I'm running doesn't have Cobra Command working, and Daphne is usltess for test/debugging code.
