Hi Our lab has a strange graphics card (SIGMA 400). It is a cga card but it does have a hi res mode. Does anybody know of a way to use it with Turbo Pascal 5.0 so that one can access the hi res? Thanks, Dan Delgado

Yes - write your own BGI driver for it (you will need to know C and Assembly as well as how to program the hardware (( BIOS, CRTC, etc )) of the board.) Before you ask me the BGI ref's are available on SIMTEL20 the file is PD1:<MSDOS.BORLAND>BGIDRIV.ARC Glen U.

If not, pick up a copy of the BGI toolkit *from CIS* (last I heard the copy on SIMTEL was an older release that had bugs). With the BGI toolkit you can create your own drivers and fonts. -- Leonard Erickson ...!tektronix!reed!percival!bucket!leonard CIS: [70465,203] "I'm all in favor of keeping dangerous weapons out of the hands of fools.

In fact it seemed to be a card ahead of it's time, back before any real high res "standards" existed...ie before ega and vga. The card is an antique, but it did have the ability to display graphics in 16 colors in 640 X 400 mode and was impressive with a high (for the time) scan rate monitor (25.5 kHz to 31.5 kHz). The card was great for text applications with a Taxan 640 monitor. Enough of the cards were sold that a number of graphics packages still support the card. The computer I am using (old 8088 system) has this same card, and I still get comments concerning the "great" resolution the system has...but then again the card and monitor were well matched, even if they do date from 1985. But if somebody wants to trade me a vga card and monitor.....
