Welcome to Ni-Wumpf, the premier producer of reproduction pinball CPU’s. Our production line currently covers the Gottlieb System 1, and System 80 games. Our company is focused on development of arcade-related circuitry – largely for legacy systems, though we have been commissioned for design work on external projects such as the bowling alley controller…

After 2 years of work, Ni-Wumpf has reworked all of their product lines, and it is time to do the same for the website. Beginning in 2026, we have new driver boards featuring SMD FETs, and laid out in an identical fashion as used in the all-in-one CPUs for System 1 and System 80 games. Speaking of which, we have released the new Gottlieb system 80 CPU now supporting all of the Gottlieb System 80 games. And, after numerous requests to produce all-in-one CPUs, we have released the new all-in-one Gottlieb System 1 CPU/driver board, and System80 CPU/driver board. These boards now support the new GTB power supply daughter boards that mount directly to the CPU board, and can replace all of the boards in the head.

Finally, we are releasing the GTB sound board to replace all of the early GTB sound boards that use the 6530, and 6503 chips to produce sounds. It also replaces the early 555 tone cards to provide actual sounds themes for these games!

Please have a look at the products above for more details.
