I have a good copy here (thanks, Jim Leonard and billdeg from http://www.vintagecomputer.net/ ) though I don't have the proper chip numbers from it. Speaking of AT 5170, if the rtc clock crystal from an AT is missing/cut off, will it boot at all, or will the RTC chip hold the PIT (and CPU) in reset forever? -- Jonathan Gevaryahu jgevaryahu(@t)hotmail(d0t)com jzg22(@t)drexel(d0t)edu
