[AH] CSQ-100 hacking CSQ-600 step/rest feature

I am looking that the schematics of both and the CSQ-600 has 2 kilobytes 
of  sequencer RAM and the CSQ-100 has 512 bytes. This makes me suspect 
that the CPU coding isn't going to be exactly the same.

But the switch matrix and surrounding logic looks the same!

So there is a step in socket on the 100 thus adding the STEP button is 
just a diode and a pushbutton.

And the B.Step is a diode, pushbutton, NPN transistor (2SC945P or 
2SC1815GR) and 1 resistor.

Then I could finally add a rest!!!!

So this will work??? Thats pretty cool.

What about the portamento button? Did you implement that too?

Also, where did you put the buttons? On first glance, the front panel 
bushings look would work as then no new holes need to be drilled.
