Auto Monitor Switcher (A1200)

Zetr0 · 04 April 2010, 01:05

Hello there my fellow forum chummies,

I have some hackery planned and I would like to make an auto-switch -> monitor switch.

I have a small digital unit, all I need is a signal I can pull from the motherboard to know if Lisa is active / AGA is active and switch, and swich again when its not

I would like to keep it an internal if possible.

should I be able to pull this off I think I could put together some very simple instructions for a - make at home kit for about $15 (yes $15 buckeroos)

any ideas / threads / links and I will be truly TRULY greatfull.

Keith my friend I remember finding a schematic back then (when I tried to make an auto switch for AGA/RTG before I decided to go with UMON and manual switching).
The schematic wasn't easy for me so I left it out but it was like Multimedia&Design's auto switch (http://www.mmd-shop.de/m-switch.htm)
I need to check my bookmarks in case I find it. You might get some ideas of how to get the AGA signal for your hackery
