[Heath] Unknown accessory board in SB-101

[Paul K. Dean]

RP was big in the 70s in after market speech processors so as you surmised, that is probably what you have. I added one to my SBE SB-34 in 1972 or thereabouts. Have a manual for it if you want a copy.

</div>Hi, folks!  received a nice-looking SB-101 today, and it appears clean so far. I have a surprise too: there's a nice looking little PC Board mounted to a small aluminum subchassis and this is held in place by one of the screws in the LMO case. I see a small toggle switch and a small screwdriver pot on the little PC Board. The label reads

R P Electronics
Champaign IL 61820
Model 3.30
S/N 00408

Since it's wired to several places on the Modulator Circuit Board, I'm not certain what it does. Does anyone on the List know about this company and what this accessory Board's function is? I'm guessing a speech processor, maybe?
