If you want a real key challenge, try those used by mid-90s IBM AS/400s. They were electronic; a lozenge-shaped slab of plastic with a bunch of contacts concealed in one end, and a chip of some kind inside (I never dared hack one apart!)
IIRC, from the time I tried to obtain a spare, they weren't made by IBM; the system was subcontracted out to a Native American owned company on a reservation somewhere. (The key in question was used to lock and unlock the front panel, select IPL modes etc) Mike On Jul 16, 2015 2:49 PM, "ben" <bfranc...@jetnet.ab.ca> wrote: > On 7/16/2015 10:51 AM, Peter Coghlan wrote: > Forget new keys ... the old key and WD-40 > Is all the keyed stuff just power on type switches > or do we have real padlocked type stuff? > > > >
