|The fabulous 1627 plotter|
In 1972, The Cooper Union Computer Center|
consisted of an IBM 1130 running BOS: Bernie's Operating System.
Bernard S. Greenberg went on to develop MULTICS.
2 IBM 1130s were donated to the college around 1980.
I used them extensively.
IBM 1130-1800 Binary Card Template
a clear plastic template held over the punched card to reveal the
54: 16 bit words in a packed format on the 12 row card.
NOT to be confused with the boot loader format or normal column-read format
(documented here as "card input" "Data Word Formats").
See here for more punched cards.
Hardware implementation, very close to exact implementation of the logic gates of an 1130 built from the IBM ALD (automated logic diagrams), plus adaption of Selectric typewriter, keypunch keyboard and other peripherals, and building light panel pedestal, push buttons, rotary switch etc with the goal of having the experience of sitting in front of and using a real 1130 duplicated. Timing accurate, including speed and behavior of peripherals. Inspired by work of others but obsessive to a new level in order to get a cycle by cycle, single stepping accurate machine.
A work in progress - the 1130 logic itself is working fine, still working on peripheral adaption, PC side links for some tasks and the physical structure.
