Hi,

> It can happen to anyone, I guess.

Yep....when I built my ZX-81 I installed a socket for a 6116 on the PCB and
built up an external 1K "RAM Pack" on veroboard using the supplied 2114s until
I could afford to get a 6116.

The circuit diagram didn't clearly explain which was the "top" and which was
the "bottom" of the expansion connector....I ended up having to plug my RAM
board in upside down (luckily the ZX-81 manual was just the right thickness to
raise the machine far enough off the table for this kludge to work). :-)
