I have a friend who collects early computer technology. In fact, he's got a bunch of bizarre peripherals that probably should be in a museum instead. Some of this stuff is so esoteric that he's had to create his own hardware just to communicate with them. (You should see the setup he's got for running his probably-soviet punch card reader... sooo janky).
Anyways, his cable management is atrocious, so when I was over at his place the other day, he was trying to figure out what some of the wires were. Instead of tracing them to their ends like a normal person (which, admittedly, would've been a task), he was reading the raw data as it goes across the wires using a strange device that would've been more at home in a questionable spy movie.
This sorta worked okay: he figured out the one for his speakers, oscilloscope, and keyboard fairly quickly. However, one set of wires was giving him a lot of trouble. These wires were transmitting the following messages in parallel:
Wire 1: VEEHVUVVEVEVUEHEGEUVHEUEHHUEGEUEEVEHVVEEHEVEVVVHUEUEUEEEEHE Wire 2: 44HIGH4GG4G4H4PGGHHGR4HGHRHHGHHG44HRG4HHPGGH4G4HHHH4H4GH4PG Wire 3: 44GSUU4UE4E4U4LNGHUUL4UEHLHHGHUE44VLU4GHLEUG4U4HUVH4U4EG4LN Wire 4: 44HIGI4G1414I4JHGHIGH4G1HHHHGHI144HHG4HHJ1GH4G4HIHH4G41H4JH Wire 5: 4EEHVH4VE4E4HEHEVEHVHEGEEHUEVEHEE4HHV4EEHEVE4V4EHHUEGEEEEHE Wire 1: VGEVEVUUEVEHEHEUVVHUEUEHEEUEUHHVHVGEUEUVVVUEGEUVHEEHEEGEEHE Wire 2: GG44GGHHHG4HGRHH4GRHHH4PH4H4HHP4H4GHHHHGG4HHGHHGRHGPHHG4HHH Wire 3: UG44EUHHHU4HELHH4ULUHU4LG4H4HHL4H4GVUHUUU4HHGHUULVNLVVG4HHV Wire 4: GG441GHHHG4H1HHH4GHGHI4JH4H4HHJ4H4GHHHIGG4HHGHIGHHHJHHG4IHH Wire 5: VVE4EVUUEVEEEHEU4VHGEHEHEEUEUEH4E4VHUEHVV4UEVEHVHHEHHHVEDEH
(The messages have been cut into two parts for readability only). After transmitting the above, there is a short pause, then the messages repeat.
Can you determine the meaning of this data, and to which device the wires are likely connected?
Yes, historical and technological accuracy has gone out the window with this one. Pretend this is a parallel universe or something. :)
