I have a PS/2 model 25 (don't laugh!) with a colour monitor. It currently is set up for MCGA graphics (which seems to be a VGA that only supports the low res modes). What I would like to do is put a cheap 8-bit VGA card in the one remaining slot, and connect it up to the built-in monitor. There may be a few problems with this idea: 1. The monitor may not be able to handle high res modes such as 640x400x256 2. The VGA adaptor may interfere with the MCGA (or vice versa) Also, I would have to fabricate my own cable... Has anybody tried this before? Did it work? I certainly don't mind tearing the monitor apart to do some tweaking. -- - Scott Nicol Email: scott@mks.com -or- ...!uunet!watmath!mks!scott SlowMail: 39 Waterloo St., Kitchener, Ont., Canada, N2H 3T8.

I have not tried upgrading a Model 25 but I have just upgraded a Model 30 (the original 8086 with MCGA). I used the ATI VGABasic-16 card (Canadian made :-) which I purchased for $115 through our computer dept. I can highly recommend this card. Installation was automatic and it has performed flawlessly with a variety of software. It is VERY small and may fit in the 1/2 slot that I recall Model 25's have. Of course that leaves one nontrivial problem - connecting the monitor to the card. I am sure the monitor will support VGA since MCGA is just a crippled form of VGA (typical IBM marketing ploy). All that should be required is the fabrication of a VGA monitor cable and running it outside of the case. I have no connection with ATI, etc. Good luck.
