Lot of 3 Vintage Lexmark Model M Clickety Keyboard P/N 1378162These are the relatively rare p/n 1378152 with
no logo badges. By 1993, IBM wasn't ordering many more buckling-spring boards from the now-independent Lexmark, so Lexmark found opportunities to sell some to OEMs (some of whom added their own logos) without worrying about offending Big Blue—whose BS patent had expired, and who never tried to patent their key layout or board design.
When Unicomp took over a few years later and designed their own BS cases, they included a larger, rectangular OEM logo area. But in '93, with BS production at historically low levels, Lexmark couldn't justify retooling unless customers paid for it.
Lot of three, all keys present, in good used shape, BIN price $99.00 + 24.99 shipping. That comes out to $41.33 each, shipped.
