I was amazed by how cool microfilm was!
Film in general is pretty awesome.
Kodachrome-64 colour slide film is estimated to yield something like 50MP of resolution, and archival microfilm goes well beyond that.
I'd believe that.
We had A4 paper blown up to what must be bilboard size by default (accidentally), and it was clear as anything!
Just, my god!
I haven't seen a SCSI card for years.....
Yeah, it was amazingly cool to see such fast data transfer on such archaic hardware. I'd never have expected it.
