MTG Kawai R-100 ROM 3x Expander Sound Switcher with *ALL* 3 R50/R100 EPROMs!

This is a new and fully functional rare “SoundSwitcher” board for the Kawai R100. It includes
ALL 3 Kawai Factory ROMs.
You get triple the sounds and it’s awesome.
Plug-n-Play, no soldering.  Highest quality switch available.  Installing it requires drilling (plastic).
Set-by-step instructions with photos are included (PDF on CD). Don’t miss this chance to fit your R100 with all the sounds made for it. NOTE: The board uses non-destructive round machined pins. It does not use square pins that destroy the original sound ROM socket.
Please note that it’s the
purple board
shown in the photos above. The circuit board is silkscreened with the signal names, so all you circuit benders out there can bend your drum machine without messing with a fine vintage instrument. No soldering is required but you may want to drill a hole in the plastic case for the switch.
The chips are
socketed
and can be replaced if you want to make your own sound chip(s).
Please check my other auctions for cool vintage synth and drum machine upgrades.
I also have available a 4x “QuadROM” variation of this board for both the R100 and a 3x board for the R50. Those use one big 42-PIN EPROM instead of the three 40-pin EPROMs that this version uses.
++Also included is a free copy of
my legendary MTG R100 Builder software
that lets you make your own custom ROMs for the R100/R50.  There is no other software tool on the planet that will do this. See my web page or blog for more. The included CD has a few features that the free download does not have.
Notice: I updated the handling to 2-days to given all the “fun” USPS is having and COVID, etc.
