Somebody fooled Google AI to believe that EU mandated RS-232 usage in 1997 :)

a good source of old manuals for 8bit isa cards

specifically including the #dtk pii-108 #rs232 card thats all over ebay. i needed the manual for the second serial port connector pinout!
Betcha John Connor would be jelly of the WiModem. Maybe I'll find out someday! 
With #Psion SIBO machines (ignoring the HC and Workabout ranges), there are two types of #RS232 port.
1. 9-pin mini-DIN. On the MC range (with comms card), the Series 3(s) and 3a (with 3Link soap-on-a-rope)
2. 15-pin "Honda" PCMCIA-style. On the 3c, 3mx, Siena
My plan today is to take a mini-DIN and a Honda cable and attach a #PL2303 adapter to each one. It won't make them any faster, but it'll be a hell of a lot more convenient!
