This is a the chip set containing the MPU game code for the SPACE INVADERS pinball.

The chip set will be programmed on your choice of 2532 or 2732 EPROMS and will come with an installed official Bally/ Williams sticker.

Purchaser must read and agree to the license agreement.

Please note the original PROMS 9316 have been obsolete for many, many years.

Unless you are already using, or your board is jumpered for EPROMS you will have to make some board modifications.

Many of the original games used 3 PROMS in position U1, U2, and U6.

To save you money U1 and U2 have been combined in one chip.

All the sets I am selling for this era of Bally are two chips.

I will program the ROMS on your choice of 2532 or 2732 chips.

Please make a note in your payment which type you need.
