The old 2 beer limit at Charlton was a bummer, but after a couple pints of 9% baltic porter, you really don't need another pour.
The real problem is having a tap-list 60 deep where you can never get to try anything (less in Tewksbury).
It's worth the trip just for the pizza, but they tend to...
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.
I was being positive, clown.
Pacman is so damn simple that anyone should be able to fix it.
...what's negative is pretending it's super complex and there's only 1-2 people who could possibly fix it, and there's no way they could figure it out themselves...
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.
I was bored over the weekend, so I removed all of the code that utilized the ALU from Sky Skipper and patched all the data that required the shifter.
The new code seems to run in MAME, but I need to pull out some original hardware to test it for real.
If the ROM is corrupt, it's probably not repairable -- unless you can find someone with a working board to dump a good copy.
You should have dropped the board off when I was at Treehouse Tewksbury last Thursday :)
Been meaning to get over there to try Hopothecary -- haven't been to Oak and...
The special chips don't work on autonomously -- they have to be triggered by code running on the CPU.
/HALT stuck high points to a code issue.
/HALT stuck low would be a blit not completing --> bad SC
Wrong.
...and there's no reason for the unprotected ROM set to NOP the $e000-e001 address (actually aliased all the way out to $FFFF, but MAME is seldom accurate) since the unprotected code simply doesn't do anything with the results of the protection reads...
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...
