Re: When I were a lad
The standard replaceable hard disk on the 3rd generation mainframes in the mid-1960s was 8MB.
In 1970 we had a 640MB fixed disk that weighed 1.5 tonnes; cabinet about 3mx2mx1m; with water cooled bearings. Someone managed to find a clever use of I/O command chains to archive it to tape in only 8 hours.
Now my Arduino happily uses an 8GB SDcard for MP3 files.
