Anyone out there have a Tek 4109 terminal, better still with manuals, and even better still with service info? Witchy chucked his one this way last night. It's powering up now, which is a start... ... sometimes it powers up to just a blank screen, sometimes to a screen with just a flashing cursor (possibly that's right behaviour :) and sometimes a blank screen along with a flashing caps-lock LED. On a reset, sometimes it gives a blank screen and two long beeps from the speaker. Anyone able to tell me what the beep codes mean, what the flashing caps LED means, and what the default power-up state should be? Possibly it's waiting for something from a host (yuck), or at least indication that it's connected to a host via serial port control lines - but the varying power up / reset states suggests that it's not entirely happy anyway... Oh, confirmation that it has all its ROMs would be nice. Of the two rows of four columns, the leftmost column is empty - is that OK, or has someone swiped those two chips for something else? Presumably the fact that it has 6 ROM chips in place (and they're externally accessible and obviously designed to be pluggable) hints that it has some sort of custom on-board app? There's a Tek tablet with it too (4197 IIRC) - no idea which of the two COM ports this should plug into, but I'd assume if the terminal was going to do anything it'd do it whether the tablet was present or not... anyone? :) cheers Jules
