Speed now & then

I’m not trying to date myself but have things truly sped up? In 1970’s Toronto I had a classic computer, sorry can’t recall what it was, connected to a 300 baud modem; by early 80’s had ‘zoomed’ to 9600 baud. Oh, my! [ A typical file size to download was probably 1 MB. ] Speed indeed! Yet now,

Re: DEC 3000 (alpha) faultfinding

On the AXPpci33 board, the SROM is also an 8 bit device. What happens is that the CPU reads in a bit stream into cache at power up reset, where the specific bit stream is selected by the jumper position on the board. In effect the SROM can contain up to 8 bit streams. Some of them will make use

If only that were 16mm or 35mm continuous rolls, instead of microfiche! In 1931, Emanuel Goldberg, then a chief engineer at Zeiss built the "Statistical Machine". By recording bits optically in the margins of microfilm, and reading them with photocells, it could find appropriate frames! For use
