Those darn 2-tone CPU sockets... How many have I trashed!

It would have been interesting to see how many QL's had to be repaired because of 'dodgy' chips, and compare with the cost of socketing some of the more common chip failure areas - in other words - was it worth the cost saving ;)

I can see why the ROM's were socketed - but even there - Sinclair missed a trick by not following completely the JEDEC standard - so although each socket does actually provide 64K addressing - you can't just throw a 27512 in the socket and be done with it.
