I was surprised they made them that small. Remember, "electronically programmable tabulator". I distinctly remember reading a sales brochure pushing that view. The idea was that (in computer terms) the thing would be programmed in machine language. Hence A for Add, S for Subtract, M for Move, and so on. Compared to the existing plug board programmable tabulators, 1400 characters of storage for data and program was huge. > No disk on the 1460 I used, but the 1440 had disk. > The 1311 disk wasn't exactly huge. 1 meg per drive. Agreed. But there was a big fixed disk random access unit (I do not remember the model number) which had a total capacity of several megabytes, more than you could get by hanging 1311's on a 1401. While a 1401 could run 1311's, a 1460 was required to operate this big beast. Bob Netzlof
