Re: Genius Mouse I have finally made the Genius Mouse GM-6000 work just as intended for the PCjr. The mouse driver, GMOUSE.COM was doing an initialization of the serial port directly to the divisor register and used an incorrect value for the PCjr. The code was MOV AX,6000 which resulted in a baud rate of 1160. I experimented by changing it to MOV AX,5F00 and 5E00 and 5D00. I settled on 5D00 because the 5F00 got me 1177 baud, 5E00 1189 baud and 5D00 1202 baud. All of the changes resulted in the mouse working very well. So if anyone else has problems getting the GENIUS MOUSE and Dr. Halo to work, what must be done is to 1st get the HAOLIBMG.DEV from the GENIUS MOUSE/Dr. Halo people, then get COMSWAP.COM from PCjr PATCJHES (or get SWAPCOM2.COM from the GENIUS MOUSE /Dr. Halo people) and change GMOUSE.COM by doing debug in this manner: debug gmouse.com -e 232F xxxx:232F 60. (at this point enter 5D like so:) xxxx:232f 60.5D (now type a w at the - prompt) -w (and quit with a q) The above items should get anyone going with the GENIUS MOUSE and Dr. Halo. I don't know if anything special is required for the 7 " power supply as I have the 11" one. Vic Bitleris
