I paid $11 each for a handful of 2508s in late 1976. A year later 2716s
were 12$. 2732s were much later and more costly, in 1979(late) I paid
a whopping 15$ each.

The halfgood part 2758 was used on the IMSAI IMP-48 in 1977!

BZZT! 2708 was three voltage and the 2716 was 5V huge
difference in pin out too.

The problem was many vendors were gouging for them and STILL!
