1979년산 키보드가 'new condition'이라는 게 믿어지지 않을 정도입니다.
거의 저 만큼이나 나이를 먹은 키보드라니, 큭큭.
그런데 XT도 아닌 25-pin parallel cable이라.. 대체 뭘까요?
XT처럼 실력있으신 분들은 컨버터를 만들 수 있으신걸까요?

This auction is for Vintage Heavy Duty Steel 1979 SKI-INMAN IBM TI PC Parallel RS-232 Connector Keyboard, SKI 7362501.  This is the oldest and rarest keyboard version I’ve ever encountered.  It is about 3.5” high/thick and connects with a 25-pin parallel cable.  When striking the keys, the keyboard feels like an old typewriter with spring keys.  There is no brand name on the keyboard, but when opened, there is a stamped name inside “SKI-INMAN” Made in USA SKI 736250.  There are also IBM, TI chips on the operating board inside and some #s:  YUF 1646303-1, F1752328-1, MFG LOC YU 1752768 EC314979 23 16474.  The keyboard is in new condition in heavy duty steel & plastic body frame and was never used since it is still sealed in a shrink wrap.  Great Collectible Piece!  Please see pictures for details and email me with additional questions.  Thanks.
