All right, Net Tech gurus, I need your assistance again... Situation: Replaced an original PC-XT motherboard with cheap XT-clone (V20 cpu; 1mb ram; cheap support chips - no C&T) (brand name = unique Turbo UX 12Mhz) Board runs but does not seem to support the original baby blue monochrome card / monitor. Runs OK with a Hercules color card and cheap composite monitor. The mono board / monitor run OK in another (original) PC (they seemed not to be the cause of my original problem - no access above 192K by p.o.s.t.). Questions: Are there known compatibility problems between these items that I should be aware of? Should I return the moth board? What's a decent monitor I could use in place of the original mono combo(using the Herc card)? (the prof I'm helping out wants better resolution at minimal cost; this system is used for manual entry of long protein and other sequences by lab slaves). Any and all help is appreciated. Email is the preferred response as I don't have much time for this group after all the other groups get read (such as c.s.amiga -- gotta keep my personal antique up and running!) paulm@sci.ccny.cuny.edu Paul Matulonis Department of Biology City College of NY

Some new M/B has different set up on swithes #5 and #6. Good luck. dlg6627@uxa.cso.uiuc.edu
