The first machine I programmed had only 8192 words, well actually 8188 [1],
but they did have 39 bits each rather than 20.

I can't find the weight of the model we had, but the minimal system (with
4092 words) was just over 800 kg.

[1] All 8192 words were present, but four of them couldn't be accessed: the
addresses went to a 4 word ROM instead.
