HP 16700 series are known to be very picky about keyboards. If you use a ps2 Hp or IBM-M keyboard it should work fine. -Rik -----Oorspronkelijk bericht----- Van: "Pat Fitzpatrick" <pjfitzpatrick207 at gmail.com> Verzonden: ?2-?11-?2013 05:29 Aan: "cctech at classiccmp.org" <cctech at classiccmp.org> Onderwerp: Somewhat OT. 16702B Logic Analyzer Woes Hi Folks, It's only somewhat OT, because I really want to use this thing to fix a floppy controller (Northstar hard sectored all discrete logic type controller) in a classic computer :) Anyhow... I'm having issues with a (new to me) Agilent 16702B Logic Analyzer mainframe and this seems like the best place I can think of to ask.. It seems to work fine except the PS2 keyboard and mouse don't work quite right. Well, actually, the mouse does work -- if I use a Logitech USB mouse with a USB/PS2 adapter, it works fine. Any "real" PS2 mouse I own doesn't respond at all -- though the LED in the mouse is on. A Microsoft USB mouse with the USB/PS2 adapter doesn't work either. Seems strange. The keyboard on the other hand doesn't seem to work at all. The three LEDs (num lock, caps lock, scroll lock) blink during boot (like they're supposed to) and there are no warnings or errors I can see reported during boot, but the keyboard is totally dead. I've tried several keyboards, on one of them, the lights don't blink either. Even on the ones that blink, pressing keys during boot (to interrupt the boot process) has no effect. All mice and keyboards work (of course) on a PC. Any ideas on where to look? Or where to find good servicing information? Thanks, Pat
