I worked in the cellar
Ambient went up to 28C
The most crucial bit of kit - and INTEL 8088 ICE stopped working.
It was full of ECL and Schottky TTL and timing was critical.
We asked for cooling. Refused.
Then I read te manual
"Equipment operation not guaranteed above 27°C ambient"
Showed it to boss, who grabbed it and raced upstairs...
Aircon arrived the next week.
