I have a XT clone that can be switch to 8mhz (Turbo) from the keyboard, however, after a software initialize to the text mode, I am drop back to the 4.77mhs mode, the keyboard switch consists of pressing Ctrl alt - (Control, alternate, minus) at the same time, can any one tell me 1) how to "lock" to the 8mhz mode? 2) how to write a program (in asm or TP4 or in C) to do the switching? rather than pressing the 3 keys? (and the turbo mode can be entered from turn on the computer?)

The manual also described how to do it with software, but I just found switching to be annoying. After about 3 weeks, I took off the cover, flipped the switch, and have been happily running at 8 MHz ever since. Fred Sullivan SUNY at Binghamton Dept. Math.

At a recent Ham Flea Market I picked up an older memory expansion
board that looks like it will be usable to up my PC from 512k to
640K. Now this board only cost me three bucks but for that price
there, of course, were no instructions. The board is marked
"Little Red", it has four rows of memory chip sockets, and a nine
pin DIP switch. The manual for my computer says the start address
for any RAM espansion must be $80000. Could some kind soul out
there who has seen one of these PLEASE E-Mail me some hints on how
to set these DIP switches?

I am searching the pins description of the Microsoft Bus Mouse in order to connect it to a 68K board. If anyone did that before, could he (she) give me the name and description of each of the 9 pins. Thank you ! Vuillamy Jean-Michel (dit Le Nain)OA
