Why not buy one of the external numeric keypads for notebooks? Most of them use a PS/2 connector, and may be enough for the PC to boot. Regards, Bill http://www.cpureview.com p.s. There are also some 'mini' keyboards about 1"x4"x12" without numeric keypad or f unction keys, would one of those work for you? ---------- From: ryan pogge[SMTP:pogge@SHORE.INTERCOM.NET] Sent: Wednesday, February 17, 1999 4:20 PM To: PICLIST@MITVMA.MIT.EDU Subject: 4x4 matrix to ps2 Ok, I reallllllly need some help here . I desperatly need to interface a 4x4 matrix keypad to a ps2 port on a PC, the buttons will mimic some of the numeric keys on a keyboard so no special function is needed there.
