Hi Folks, See http://canola.sourceforge.net/ for the current state of the emulator.
The staff at the Power House Museum were kind enough to let me play with their 1614P for an hour or so, so that I can build a more faithful emulator. The pay-off for them, if I do a good job, it that they can use a modern (cheap) PC running the emulator (it's GPL licensed), in front of a glass case containing the powered-down original. The price on the original was circa $1200 in 1972-ish, ouch! Amazingly, all the Nixie tubes and incandescent lamps still work (this was pre-LED era). It turns out the internal state machines are much dumber than I thought; transistor densities weren't high enough back then to "waste" them on elegant handling of "wrong" input. The staff also let me scan the library of program cards that came with each 1614P. Last night I wrote some image processing software to rip them to extract the code. Just now, I found bug in the sin(x) code. Only 39 years later. Can anyone spell Unit Test yet? -- Regards Peter Miller <pmil...@opensource.org.au> /\/\* http://miller.emu.id.au/pmiller/ PGP public key ID: 1024D/D0EDB64D fingerprint = AD0A C5DF C426 4F03 5D53 2BDB 18D8 A4E2 D0ED B64D See http://www.keyserver.net or any PGP keyserver for public key.
