In chronlogical order (some machines were sold, some unmamed later, some converted back to pcbs later, one went in the dumpser and many were traded).
Pac-Man converted to Capcom Bowling. Then painted Pac-Man yellow. Eventually dumpstered. (This was a POS anyway).
Defender converted to Double Dragon. cabinet sanded down, painted gloss red, ran a frankenpanel for awhile, eventually sold the empty cabinet.
Carnival cocktail. Mame for a while, traded empty cabinet later, was not modified in any way, recieved it empty traded it empty.
Galaxian that was painted brown and converted to Clutch Hitter. Received Pac-Man panel, bezel, NOS Pac-Man Plus marquee. artwork kit later sold and cabinet redone with a Top Gunner kit, then sold.
King & Balloon - dedicated ATW bootleg mini. Boardset was missing, no one has working bootleg pinout King & Balloon boards. It is now labeled Galaga and sitting in my living room in working order.
Amazing Maze. Was dedicated, complete and dead, dead, dead. When I got it. The original game sucks. Would have cost $130 to fix the boardset, no one (myself included) would have paid $130 for the dang thing in working condition. Parted it internally for closer to $200. It got a fighter panel and VGA monitor. Was later robbed of its PC and I-Pac for another project, and is currently sitting in my basement. I still have the original panel.
"The Shadow" Video poker, purchased fully working for $50, parted it, then mamed it, gave it as a gift.
Space Firebird mini - Was dedicated and complete when I got it, also had a problem that no one knew how to fix, parted the internals, swapped the stick with an 8-way, kept it MAME for a year, then sold it at superauctions.
Dynamo Tournament Solitaire. added red wico joysticks and buttons to the machine which already had VGA monitor and serial trackball. Replaced factory PC (which was horked), with a p2 400, traded it for a pinball machine.
Gorf cocktail - Unchanged externally, still in my living room.
"Darwin 4078" formerly a Frogger type cab, but not a Frogger. Got TRON layout + 4-way and an NOS Road Fighter artwork kit. Was built to order for a customer.
Defender- empty, dedicated. Mamed, control panel is Defender layout with Defender overlay, only runs 3 games. Still in my living room today.
Probably forgetting a couple.
Originals I have that MIGHT still get Mamed.
A Stargate cabinet (empty cabinet with sideart, original panel in bad shape, and "Capcom fighter" panel in excellent shape.
Sega Turbo (unsure if it is complete, all the parts are in boxes, monitor and boardset both have problems).
Atari Basketball (Complete)
Sprint 2 (I have two of these).
Battlezone (made a double decker panel for it, hated the look and dismantled it). Just an empty cabinet, missing most everything but step and coin door.
Some Universal cocktail, can't recall the name. No monitor, no PCB.
Millipede - Empty cabinet, had been converted to Time Soldiers. I stripped off most of the paint to get the sideart back. This has no Millipede parts other than the power sled, and the only Time Soldiers part is has is an unpopulated panel.
A Gorf upright, nothing inside, and the control panel is unpopulated.
I probably have other stuff I am forgetting, I can never quite remember how many machines I actually have at any given time.
