I'm finally getting all of the pieces and knowledge together inorder to try getting my 25kHz monitor to properly display the advcfg setup screen.  I'm going to try these steps tonight:
- set pclock at 5-90
- set hoz freg at 24.9 KHz
-set vetical freq at 47-63 Hz.
- play with shift 'i'
-increase/decrease horz freq by .01
-repeat until screen is viewable. 
-Does anyone know if any special lines in the rc file  are needed for the tblade 64, or any TSRs?  Remeber this is for DOS using a WG U3000 EGA arcade monitor.   Anyone want to add anything?
Thanks,
Charlie
