Please excuse me for this stupid question: what is the deal with these elusive "TI" sockets that some builders allegedly prefer for their Apple I clone build ?
To be more specific:
a) What is the wanted difference to less elusive IC sockets of the non-machined type ?
b) Did all original Apple I use low-profile "TI" sockets or are some originals out there using higher sockets (7.6mm height being common "boxy" style sockets, easily obtainable).
c) The height of these elusive "TI" sockets which are the "correct" ones.
In the end, it boils down to the following scenario: if someone glances at the clone in sufficiently low light conditions, machined pin type sockets still can be recognized instantly as a giveaway it's a clone. These sockets are more reliable, though. But if somebody seeks authentic looks in low-light conditions, which are the socket types that are best ?)
(If you ever wondered why many museums have small, low-light side rooms to display certain exhibits you now have the answer: the exhibits are either replicas or light sensitive. More often than not it's the first reason for keeping lights low).
