final freeware version of video test bench
VIDEO TEST BENCH 4.5F FREEWARE this was a DOS program i wrote back in the 1990's to test CRT monitors. there are test patterns for everything from IBM monochrome to SVGA 1024x768. there are also test loops for "burn-in" testing. the original hardware requirements to use this software as a "universal" monitor pattern generator was a trident or oak card with the mode setting DIP switches to set the card to MONO, CGA, EGA, VGA or SVGA. the software autodetects the switch setting, and starts up in the appropriate menu. i released this freeware version in 2011, which is the complete software with over 100 test patterns. when i released it, i didn't think to release the source code, but i am including it here. to build from source code requires QuickBasic 4.5 and a shareware library called QLIB58.
the software seems to run ok on most standard VGA/SVGA cards.
instructions for using vtb45 are included in the zip file. i will not be making any additions to this software as it's an old project.
