Multiple Vintage computers with one display

[sciencegirl100]

So, my dorm room doesn't have much space, and I don't have a lot of monitors, so KVM switch to the rescue.
Oh, wait... I don't have a KVM switch... yet. I'm working on making one (without the K or M) out of a parallel switch box.


I'll post a picture of my progress later (today or tomorrow).

The hard part is all the VGA -> composite conversion! :D

Why bother with that when composite switches already exist and were cheap? Thus only need a single converter.

You realize you can buy a 4 port VGA switcher in Amazon for like $21 right?

EDIT: Here is an even cheaper one ($14) https://www.amazon.com/dp/B01HOCUOSO/ref=psdc_15782091_t3_B01C8I9R2S

EDIT 2: How about $8 - https://www.amazon.com/dp/B00MHQ2LW0/ref=psdc_15782091_t3_B01HOCUOSO

If you have multiple machines, some have composite out, some have VGA out. If you're only using one monitor, in most cases you'll need to convert all of one to the other. Or, you need three switches.

Ok, I'm not using any composite video, just VGA.
And I don't really have very much money to spend, and I already had the switch.
