I can hook up the cable that came with my legacy base but I cannot get my cab 2 to operate my asc's, bpc's etc. Any tips or solutions would help.

Not reallly. It is "RS-232-like", operating within the narrower voltage swing of zero to five volts, and sourcing substantial current.

Looking at the CAB2, the output is +/-8v. So I wonder if there is some future reason for the RS232 rather than the "RS232-like" which is what the CAB1 used. I take it, as per your parts list, the 3904 pulls the base of the 3906 lowish and the output goes to +5 v...like the output of the CAB1.

Also, the emitter-base breaks down at 6 v. Is a diode necessary there (after the 10K resistor input) because of the -8v from the CAB2?
