 Ah, yes - page 232 - fig 13.5 there is the big TRW multiplier chip.

Note that the DMX1000 digital synth is driven (housekept?) by a DEC LSI-11
with an RX02 clone (looks like a DSD unit) for storage... and the
requisite VT100.

  Damn: wouldn't it be Cool if any of those were left forgotten in some
closet somewhere?

  Remembering that this is circa 1978/9 - some specs listed:

"AT a 19.3 kHtz sampling rate it will implement, for example, 24 simple
oscillators, or 16 oscillators with ramp envelope control, or 8 voices of
frequency modulation, or 20 first-order filter sections, or 10
second-order filter sections, or 30 white noise generators, or various
combinations of the above, such as 12 oscillators and 4 voices of
frequency modulation"

  [from the 4th printing of 1988 - the first edition came out in '85.]



 Cheers

John
