In the ancient year of 1980 I started college at Northwest Nazarene College, majoring in Engineering Physics.The ram will be empty microseconds after the power is removed.
The physics lab had two identical Commodore PET computers, already obsolete. This model had a primitive frame buffer backed by dynamic RAM, possibly Intel 2116 with a 2 ms refresh cycle.
These PETS had the curious property of displaying old display data, retained in the DRAM, briefly as they rebooted. I remember playing (...I mean...conducting careful experiments) with this and being astonished how long some parts of the old data would persist during the powered off period.
