Funhouse Playing Tips and Rule Sheet
Funhouse strategy video from PAPA
Funhouse is one of the first games to use the basic WPC platform of WPC CPU and WPC power-driver board. Early versions used the System 11 sound board with an adapter. This version of the boardset is not compatible with the L9 software version. Later versions use the first WPC sound board. Funhouse is an alphanumeric display machine. It uses the "DISPLAY" header on the CPU board. Note that in WPC DMD machines, the DMD controller board connects to the AUX and I/O headers at the top of the CPU board. The DISPLAY connector is uses for auxiliary I/O in a DMD machine.
1 Game-Specific Issues
1.1 Upgrading to L-9 ROMs
The latest version of the Funhouse game ROM is L-9. With this version the game ROM has increased to a 2M ROM from a 1M ROM. A jumper on the WPC board must be moved to use the larger ROM. The jumper at W2 must be removed and a jumper at W1 must be added. This is a somewhat simple board repair but if you do not have board soldering experience any pinball tech can make this modification. A detailed explanation of this process can be found at John Wart's pinball website. as well as a discussion at rec.games.pinball.
1.2 Servicing Funhouse and Roadshow Heads
Full of tricky, but now-available parts, these heads are straightforward to service. There still seems to be an issue with poorly-made jaw gears that fracture early in service.
1.3 Choke Coil
Some (perhaps later) Funhouse games have what looks to be a standard coil adjacent to the backbox tweeter. This is, in fact, a "choke coil", which changes the audio range of the tweeter. It is wired in parallel with the tweeter. the coil should have a resistance of .6 - .9 ohms.
