and Some Background Information
The IBM 1130 was one of the more popular
computer systems to be used for electronic publishing. Its lower cost
(about $1250/month, minimum configuration) was much
cheaper than S/360's) and the advent of phototypesetting,
expanded the marketplace. However,
The basic cpu and console (on the left) had 8K of 16-bit words (16K bytes) of magnetic core memory. Adding another 16Kb cost an addition $500 per month! Programmers watch their program's byte count very carefully in these days.
The IBM II30 also had 512K words (1mb) of on-line disk storage and the disk cartridge was removable. It rotated at a speed of 1500 rpm, and had a transfer rate of 27.8 microseconds PER WORD, or 72Kb per second. You could listen to the disk arm move via the voice coil, which had an OMMMM sound on long moves and IMP sound on short moves. Where you put things on the disk was extremely important at this time.
The 1442 Card Read Punch could read 300-400 cards per m inute, and punch one card per second.
The 1132 Line Printer printed 82 lines/minute, and was 120 characters wide. It had a printwheel of 48 characters for each of the 120 positions. Because all similar characters were printed at the same time, core dumps (lots of zeros) caused it to make a very distinctive CLUNK sound quite often.
These 1130 systems were also configured with one or more (up to 16) Teletype High-Speed Paper Tape Readers (CX) and Punch Sets (BRPE), both operating about 110 cps.
Around 1968, there were only two of these IBM 1130-based typesetting systems in Kansas City; one to drive the Photon 560 and Photon 713 phototypesetters at Computer Photocomposition of Kansas City (Missouri), and the other to control the Linotron 505 at Mission Photocomposition (Merriam, Kansas).
