Mendelsons Surplus has re-listed, on their website, the Japanese version (p/n 6112883) of the vintage IBM "Pingmaster":
NIB IBM Japanese Lettering Typing Computer 102 Keyboard Letter Type 6112883Though they continue to sell the Chinese version (p/n 6113442 )
here on eBay, most of us assumed the Japanese version sold out some time ago. This should be good news to several GH peeps who were sorry they'd missed them.
These are
unused, high-quality vintage IBM mechanical keyboards sealed in their original boxes. They have double-shot SA keys (not seen since IBM's early beam spring boards), rare "T-mount"
Alps SKCC Green switches, and many custom-legendable keys with transparent covers. It seems likely they were designed for financial institutions, as they closely resemble IBM's
Model F banking boards.
GH members have dubbed these "Pingmasters" because of the unique "musical" sound produced by their unusual switches and heavy metal plates.
There are
several threads about them here on GH, and Chyros
did this swell video review.
Note that these have a non-standard connector and protocol—so to use them with a modern PC, you'll need to add and program an inexpensive
Teensy converter, which anyone with basic electronics skills should be able to do; details
here and
here.
At just
$24.95 plus shipping, it's a pretty remarkable chance to own an obscure piece of IBM history.
