These pinouts should work for Frenzy as well. To switch games, you should only have to switch the ZPU-1000 board. I believe the Frenzy board is ZPU-2000.
The complete boardset includes these 6 boards: ZPU-1000 [CPU/ROMs] SB-1000 [Amp] VSU-1000 [Sound/Voice] BSC-1000 [Video] VFB-1000 [Video + Controls] RCR-1000 [Interface Board to controls + video]
Optionally, you may also come across the Power Supply (PS-1000), Heat Sink (HSA-1000), transformer, and line filter.
Here is the board layout:
If you lay down the boards exactly like the diagram, all the game bus connectors align themselves. The games bus connectors are all 23-pin small-width MTA connectors, except for two 18-pin small-width MTA connectors at locations J3 and J4 of BSC-1000 and VFB-1000.
