My first experience was with an IBM 2560 on a 370/125.

The IBM 2560 Multi-Function Card Machine (MFCM) provides the System/360 Model 20 with a unique and versatile input/output capability. It combines the facilities of a card reader, card punch, collator, interpreter, and card document printer, all under control of the Model 20 processor. (See Fig. 1.) Two card hoppers, an optical read station that reads both primary and secondary cards, a common punch station, an optional printing station, and five selective radial stackers provide the Model 20 system with a card handling capacity never before possible with one pass of the cards.

Using the letters "MFCM" was not well thought out in advance... it was a highly effective card shredder at times :-)

(I admit I could miss the information in the thread)

What was the speed of tape reader or card reader?
Of course I don't mean the device in motion transported on the wheels, but rather data transfer in bytes per second. ;-)
