What aniquated programming device is this??? What chip are you programming?
Since you already have a working computer (in order to post here), get yourself a real programmer that connects to it.

I remember doing that back in 1971 on a PDP11 copy that our company designed and built to control CNC lathes......12 bit op codes, diode matrix microcode, 16K ferrite store,120 ttl chip ALU,etc etc. Had to enter a boot loader that read in a punched tape that had the application program on it.... sweet memories .)
Your school needs to seriously upgrade their equipment.
The easiest way to do this may be to program a microcontroller to read the hex keypad, and use open collector buffers at the 16 output bits to simulate the DIP switches. ;-)
