Foto-Mem
Foto-Mem Inc. was a US company that attempted to introduce very large computer memory systems based on optical storage on microfiche cards. An alternate product line based on the same mechanical systems allowed a single microfiche card to be displayed on multiple workstations, intended for large libraries where a single card might be used by several people at once. Only one such system was ever delivered, a microfiche reader for the New York Times; this system was never successful and the company failed as a result.
