Hi John,
as always a great article.
A small correction:
"These particular chips were made in 1993, a lot can happen in 37 years of storage and transport around the world"
They are 27 years old, not 37

Up to now,I understand the VQ80486DX4-100 for what mean. thanks John. |
VQ is a bit different still
VQ is miltemp only, no other standards met (also have seen VA80960s , same deal there)

|
MQ is miltemp and spec (voltage etc and usually 883 compliant)
TQ is extended temp (less then mil temp)
VQ is mil temp only NOT tested to 883 standards
