After reading a brief query in info.ibm-pc regarding incompatibility between the Sperry PC and an EGA card, I was wondering if the same applied to the Sperry IT. I am seriously considering the purchase of the Sperry AT clone but definitely want to attach an EGA of some kind to this machine. Does anyone know of any problems in this regard? Has anyone had good or bad experiences with the IT period? I'd very much like to know and, as usual, thanks in advance. -- Jay Elvove ..!seismo!mimsy!jay

We use a Sperry IT in our business with AutoCad. We were unable to make a match between the Sperry Monitor and graphics cards and AUtoDac, but that might have chjanged since ( 6 months). We bought the Sigma Design's Color 400 board and Princeton SR12 monitor and get 640x400 with 16 color from the combination. We are pleased with the Sperry and these cards with one major exception: We are unable to get the computer to recongize more than 512K with our losing the monitor display!!. He have a full 1 meg installed but when properly addressed, it won't work. I've heard some comment that the problem relates to having a first out computer mother board and that the revision now would work, but I have not had a way to prove this, let alone wondering what I can do about it if I do so. The IT comes with a 44 meg HD and serial and parallel ports and can handle more devices in the 'box' than an AT. SysV is available for it now, and it runs well from what I've seen on a system I've observed. Oh, yes, I do know that the Tecmar color card also works fine, I've tested that with a CUB monitor; naturally it is interlaced while the Sigma is now, and there is no flicker. . -- Robert L.
