I helped my brother-in-law install a 1MB hard drive on his TRS-80 computer.

It was the size of a record player and had to be started with an actual key. You had to let it spin up to proper speed before it would work.

It was 1983.

Do you know the year of this ad? Never heard of XCOMP before.

By the way, does anyone know about the computer used by the first men on the moon? I guess it was less than 1MB.

I think the Apollo command module had a 64K computer on board. Might have been even smaller than that.

The MB/dollar ratio suggests early 1980s. XCOMP was, I think, a short-lived manufacturer of HD control circuitry from about that same period.

1982, September, from Google. Sounds about right. This is a pre-PC, S100-bus system.

Thanks Peter. I even followed the link, thinking it was an acronym, wondering why there were no references to it in enrico's link, etc :-)

Made my day (so far) :-)
