Yay! and Yikes! in the same breath! A colour microbee in good nick!
However, they're bastards to work on! (Cut PCB tracks and a bunch of spaghetti wiring!)
From the photos:
a. Those unsoldered DIP pins are normal, they're where the wirewrap sockets from the baseboard mate with the colour board.
(Yes, you can remove the colour board if you really want but it is fiddly.)
b. Thank goodness you removed the leaky NICAD battery!
c. You can construct your own composite cable to connect to the colour port.
d. Power up the microbee using a lower input voltage (lower is better!).
A suitable variable DC power supply is ideal where you vary the voltage from 8V to 12v.
It's a great sign if you can power it up and get a beep!
If you don't - no don't fret.
Please place and update post once it's powered up (beep or not).
