[GreenKeys] The last of the Pasco 35 ASR photos .. for a while

[Pete Lancashire]

Looks to be DTL TI numbers SN15846N is a 836 DTL QUAD 2-INPUT NAND GATE,
SN158099J is a DTL JK Flip Flop. The N suffix is Plastic, the J is Cerdip
and the SN prefix basically says it is TI.

One I can't find is SN97096J, other then with Teletype P/N on Ebay of all
places.

I'll bet this is a RS-232 translator.
