[1] I do mean
_iompossible_. I ended up using part of a 7483 that I stuck
to the flip-chip PCB dead-bug style and wired to the holes where the 7482
should have been. Runs fine...
Bzzt. Wrong. (First, you probably mean "_impossible_" :-)).
I just bought 5 of them for US$1.25 (or so) each from
Gateway Electronics. Along with spare 7453, 7460, 7440, etc. I think it's
something like "gatewayelex.com".
Notice I said 'was impossible to find'. At the time I was repairing this,
some 10 years ago (Eeek!), no UK supplier could supply them (and I
tried...). This was before the Internet was commonly available in the UK,
and we didn't really know the US suppliers of old chips.
