Custom Acclaim microchips

[ASSEMbler]

I'm working my way through the thousands of ICs from acclaim's arcade and dev division.

I found some custom acclaim chips, with no data sheets.

The chips read:

ACCLAIM
lz95a53
9447 T

It's probably made by sharp.

Anyone feel like having a go at figuring out what they are?

[HHogan]

lz95a53 = chip id#

9447 T = video chip classification IIRC

Doesn't help much because you already said it's from their arcade division, so they are most likely chips from the board.

If it's from arcade boards, The guys from mame would like very much.

could be ROMs I guess... but then again, could be something else.

How many pins are they?

According to KLOV Acclaim only made four arcade games and most of them seem rare so you might have something of value.

Batman Forever (1996) - The game uses Acclaim's RAX soundboard and Sega's Titan architecture. Believed less than a thousand made.

NBA Jam Extreme (1996) - No technical info

Judge Dread (1997) - No technical info

Magic the Gathering: Armageddon (1997) - Acclaim's arcade chipset is called Epidemic. The 3-D polygonal graphics are powered by a dual-processor Obsidian 3Dfx board. Arcade division closed up shortly after completion. Never went into full production.

Yeah I have a lot of the chips and 3dfx boards.

Do you still have those old Voodoo SLI cards?

I would like to see what this was like. God could not afford those Obsidian boards (back in the day, anyways).

Interesting details about their ST-V game, Batman Forever:

- it was the only US-developed game for the system
- also, the only game not to use the board's cartridge slot, but rather the expansion connectors
-it ONLY runs with a US bios
-it sucks!

[subbie]

have any of the arcade dev hardware by chance? :D

[ASSEMbler]

Actually yes, I do.

I've always wonderd except for the obvius things like (e)eprom burner, solder iron and assembler code. what do they use to create arcade games? or is that all? :D

And after all that i wonder why they bother making home ports :D

[subbie]

Actually yes, I do.

Price? :D

Both NBA Jame Extreme and Judge Dredd run on Sony ZN1 Hardware.
Very similar to Playstation hardware from what I understand?

[Keiyentai]

could we see pics of the chips by any chance. Would be cool to see them.

[retro]

Price? :D

Haha, good luck!!!

If i remember right it's a R3000A (PS1 Cpu) with QSound (the capcom hardward sound system).

me too.
atari used quantum 3dfx boards for various other arcade systems aswell(san francisco rush on flagstaff, for example).

there was a pc port of san francisco rush: the rock that was bundled only with quantum raven graphics cards, i've been trying to get my hands on that for quite a while now, seems to be kinda rare nowadays.
most people keep the card, but throw away the box and the software that came with it. ~_=

anyway, pictures of these custom chips would be highly appreciated. =)

Here's a link to flickr with several shots of the Magic:Armageddon boardset. -

This machine is actually owned by someone that was a programmer on the arcade game. He was kind enough to snap some pics as well as scan and upload the manual for the game, this was in reply to my query on hooking up the boards, as I recently picked up the boardset, wiring, control panel, and marquee. Here's a link to my flickr page w/a few pics of the boardset and control panel -

I picked up the main board, labeled Typhoid several years ago off ebay, around 2000 maybe. I never did find the two other boards, the JAMMA/sound board called Mad Cow and the video decoder card called Pink Eye (if I remember the names correctly). The whole Magic:A boardset was called Epidemic if I remember correctly.

Here's a link where you can download the Magic:A manual, I don't think Mr. Corey would mind -

I got the setup from a friend who won the auction for it a few months back, the machine was in Sweden if I remember correctly, and the friend just had him kit the machine and send him the guts. I thought it was a bit of a bummer but the cost to ship the machine was over 1k and FA wasn't exactly being responsive to my queries about the cheaper boat method (they blew me off).
