Yes, but the SDK85 design you could jumper the IO for
RS232, 20ma or TTL.
OK, I am being dense... The schematics I have (which I will admit is
printed in a book, it's not an Intel original, but it does say
'Reproduced by permission of Intel Corporation') doesn't appear to show
any such links. It just shows 1-transistor buffer stages connected to the
SID and SOD pins.
Can you point me at a schematic of the SDK85 that does show these
jumpers, please.
