 Help - I have a Tandy 1000SL onto which I installed a Orbit VGA 100
 Board and an IBM Model 5175001 display.  

 Previous to this installation the Music function of Desk-Mate worked
 with a mono-monitor. (MUSIC.PGM still works fine on a Mono if the
 VGA board is removed.)

 Now, however, anytime I enter MUSIC.PDM, the system locks up and a
 boot is required.

 At first it was suspected that it was an interrupt problem, but 
 considering that other sound/music programs work fine and do not
 exhibit this problem, it is probably not an interrupt problem.

 Software is MS-DOS 3.3 and Desk-Mate 3.0.0 - Any help will be appreciated.
 Additional information, this is the ONLY program that fails, so
 it may be software, but I don't get any good answers from my local
 Radio Shack people.

 Hardware configuration is: 640KB of memory, 40MB hard disk, 360KB
 floppy, 2 serial ports, 1 parallel port.  SETUPSL command has been
 executed to lower the video memory assigned to the lowest that Tandy
 software will accept since the VGA board has its own local memory. 

 Send e-mail direct if possible or snail to:
