This was for a friend of mine who wanted a MAME cabinet. It was not
my cabinet, I cant fit another cab in my apartment. It is a
conversion of a Neo Geo cabinet. The Neo Geo cab was a good choice because the Neo Geo
cabinets were pretty generic to begin with so no big deal to chop one up. It
also had a non working tetris system in it. I dont see tetris being very
popular today and the power supply was dead anyway. I tried one of
the IPac controllers from ultimarc.com on this project for a 2 player system.
It is very nice and much easier than a keyboard hack. Also much cheaper
than the hagstrom decoders. The pdf manual did not give a pinout
so it was not clear which SW1 was player 1 and which SW1 was player 2 so
I wired up as a best guess and it was backwards. Fortunately the keys
can be easily reprogrammed in software so I changed the profile and did not have to rewire
anything. It also has a 'shift' key which lets you change the button
function to another function. This is great if you do not want
extra buttons on the cp for tab/pause/F3reset/etc but still need those functions.
I can see this being really useful if someone had multiple control panels, just replace
the shift momentary button with a toggle switch and you can use the same ipac
while switching out entire control panels for stargate and robotron for example.
One problem I noticed with the ipac is that they bios does not support
repeat when a key is pressed. This is annoying when trying to scroll
through the game listings and nothing happens.
The monitor was replaced with a vga capable arcade monitor. It worked quite
well but I had to turn the brightness down to zero even with a smoked glass
cover over it.
There was a place in the middle of the cabinet where I could fit
a marquee, instead of at the top like most cabinets. There was no room behind it
so I bought one of those computer case, no heat, lights made bywww.thermaltake.com to put behind a
marquee and give an eerie blue glow. I got the idea when looking over
ebay marquee auctions and a mame marquee was shown with a blacklight
behind it which is something I had not thought of before but it looked cool.
I could have also used some of the new high output LED's available from radio
shack or similar companies for this space.
There were no lights behind the coin slots. I like lights illuminating my coin
slots so I picked up some 6v lamps at radio scrap and found an 11vac power
converter. Using the converter meant I did not have to steal 12v out of the PC.
Speakers were mounted but not used like this, a plug wire was run to the existing mono speaker.
