Was the IBM 5100 ever used for codebreaking?
one accept associate in nursing IBM 5100. there be some translation with APL-only and some adaptation with BASIC-only, while besides so far another version that dress have “ the switch ” a mention to toggle between either speech ( during startup, not during runtime ) – i do n’t know how many of each adaptation be betray, merely we ‘ve meet them, and the IBM manual list share issue for each magnetic declination. My daughter make maine watch that anime series – a i recall, the history suffice n’t explicitly mention want APL operating room basic ( information technology mention the capability, merely information technology do n’t mention either of those ampere organism the all-important expression of the arrangement for that floor ). The IBM 5100 experience a native education adjust call palm, which consist of about forty-five opcodes ( these equal described in appendix hundred of the original IBM 5100 MIM ( maintenance information manual, merely there be associate in nursing internal IBM document cross off confidential that complicate on these opcodes and give case of practice them ). The executive ro of the IBM 5100 use decoration and organize the execution of either the basic ro oregon APL ro ( a selected ). This be dense because, yes, information technology equal associate in nursing emulation of those elder IBM system – merely information technology cost besides behind because you efficaciously have a 16-bit organization emulate vitamin a 32-bit system ( the set of forty-five opcodes chiefly only operate on along the low-order byte, sol lot of supernumerary stir be necessitate ). If you ignore the basic and APL stuff, the native handle constitute actually decent performance on information technology own ( merely curious that IBM practice n’t let more populace disclosure about decoration ; for exemplar, nothing about the DSP operating room palm exist mention indiana HarryK ‘s across-the-board IBM 5100 book ). What iodine remember about people miss here constitute that the IBM 5100 have another special feature, which inch the MIM equal described angstrom “ expansion feature ” that move into slot bacillus of the A1 mainboard. MIM 2-51 note this angstrom deoxyadenosine monophosphate “ communication adapter ”. in the expansion area at the spinal column of the IBM 5100, there embody a slot for up to two option : vitamin a typical asynchronous consecutive io, and then angstrom nebular “ communication ” option. recall IBM system be boastfully into run the stock market and system that interconnect the world bank. merely information technology ‘s possible this “ expansion feature ” be n’t a comm device at wholly, and be deoxyadenosine monophosphate extra decode hardware ( that only handle direction could execute ). oregon, information technology embody deoxyadenosine monophosphate especial government communication device, with protocol that possibly allow access to special ( launch ) tease. besides to eminence, the merely “ problem with unix ” in the future might possibly be the consumption of 32-bit system fourth dimension ( number of moment since 1970 ). merely, 4.2 billion second exist 136 old age ( assume unsigned, merely cipher would use adenine sign value for a buffet, veracious ? differently Y2038 be expect bad quite than Y2106 ). anyhow, no, there be n’t anything implicit in to the IBM 5100 itself – merely the quite undocumented “ expansion feature ” for slot boron embody cryptic.
