Summary: Can an XT clone support both a bus MS mouse and a VGA? Message-ID: <5206@watdcsu.waterloo.edu> Date: 28 Oct 88 00:49:16 GMT Reply-To: dmurdoch@watdcsu.waterloo.edu (D.J. Murdoch - Statistics) Organization: U. of Waterloo, Ontario Lines: 11 I just bought a Microsoft bus mouse for my XT clone. (They're offering an excellent educational discount.) When installing it, I found that the only interrupt line I had free was IRQ2, which is listed as conflicting only with an EGA and a network adapter. I don't have any plans to get a network adapter, but would like to upgrade from monochrome to colour. Does the VGA also use IRQ2? If so, is it possible to double up devices on IRQ lines without killing everything? Thanks for any help. If it's email'd, I'll summarize and post. Duncan Murdoch
