I constructed my MiniWave with a Stooge front panel setup for a Hylander ROM expander board and a Tellun JLH2090CV board.
I have these ROMS installed:
ROM-1: Socket Rocket
ROM-2: GR-PPG/P-V5 by Grant Richter
ROM-3: GR-New.256 by Grant Richter
ROM-4: Morphine by Mathew Davidson
ROM 5: Serge Creature "Pocket Monster" by paperkettle.com
ROM 6: Schumann PLL by paperkettle.com
ROM 7: Commodore 64/NES "ROM1" by paperkettle.com
ROM 8: Ensoniq SQ80 Wave1 by Patrick Joericke
ROM 9: Ensoniq SQ80 Wave4 by Patrick Joericke
I brazed together several pieces of aluminum to build the chassis to mount these three boards to the front panel.
As I added more ROMs I had trouble with reliable operation which was due to the chip enable of ROM-0 not meeting the Vih specification of 2 volts. R18 pulls up this chip enable to VLED which was less than 2 volts with the forward voltage drop of the LEDs I used. I corrected this by connecting R18 to +5 volts instead.
Here is my MiniWave waiting for 5 more ROMs.
