You beat me to it :-) That was my guess, too - the only such box I've got here 
though is a GCC RAMROM-15 and that uses a 40-way cable (plus the beeb 
interface plugs into the 6502 socket I seem to remember, not a ROM socket as 
yours appears to).

I'm not sure why the cable would show signs of two external connectors though 
(unless it was possible to drive more than one external unit - but 34 lines 
doesn't have much scope for control and addressing).

Given the length of the cable, it seems unlikely that it was just some form of 
ashtray-based ROM cartridge or whatnot.
