I have recently acquired for next to nothing an IBM 3270 PC with a 5272 color monitor. The problem is that although colors work fine on the monitor, no graphics show up at all. System info claims that CGA is in place, but when I tried replacing the graphics card with a standard CGA card I saw nothing but garbage on the screen. A call to IBM revealed that the ROM's are not able to recognize graphics calls, but I was wondering if anyone knows of a 3rd party board that might have been built to work around this problem. Thanks in advance, Ed Friedman INTERNET: ed@zaphod.uchicago.edu

Borland's Turbo C++ had a separate driver for the 3270 pc, to the best
of my knowledge, for their BGI graphics package. This would indicate
that it isn't a CGA, but has other capabilities.
For what it's worth
