[vcf-midatlantic] Memories of 1977

[Joseph Giliberti]

Greetings!
I'm still in planning stages for my homebrew computer and one of my goals
is to keep it period appropriate. Part of that is not using any parts or
technologies introduced later than 1977.

I want my computer to have at least 32k of SRAM. So, by the end of 1977,
what was the densest chip commonly available which I won't have to go
bonkers trying to locate?

Thanks
Joe Giliberti
