I recently tried to install a 286 accelerator board in an old XT.. Just grabbed a boot disc out of a pile and powered up this old clone. What I thought the screen said was" A20 line error," (it is an XT) when upon being corrected by another member of the forum, I tried it again It was an "come from 20" that the screen showed.. Part of the disk has a program written by Intercal 0.15 does anyone know what that is??? :confused:

A20 line coincides with the 286 and highers ability to address the first 64 kbyte of extended memory above 1mb and with the keyboard controller?

Possibly you don't have something connected or maybe you need to install extended memory to the board, not sure.

Do you have a picture of the overdrive you installed?
