Apple IIe enhanced -only outputs B&W

Hi

sometime ago I posted about an issue on a PAL iie enhanced; it seems to output B&W video only. At the time the outcome was the PAL machines may still only actually output NTSC, or NTSC 50hz, so my PAL-Only CRT likely was going to show color, only B&W.

My own outcome was, as my PAL CRT monitor was known not to sync to a NTSC signal, to give up on that until i had an NTSC capable monitor.

a year later I'm in canada and i have a NTSC monitor and an PAL LCD tv that definitely handles pal and ntsc(several versions, 3.58 etc). But still there's no color!

so

-has anyone got /seen a pal iie outputing color at all?

-name a few games that are color for sure in case I'm running B&W only software.

-what now. I do have a spare motherboard from a iie platinum, I could swap that in and test that.

- I'm connecting the iie's built in compositive video out, one phono<>phone lead straight into the monitor or tv. no special leads are required for colour are they?

The only thing I'm doing thats odd, although its not upset any of my other PAL retro computers at all - is that my 11e is 240v 50 hz and I'm running them on a step up transformer ie 110v, but now 60hz. Hope thats unrelated.

ideas?

cheers, Iain

Apple ][+ Keyboard Help (1979)

Hi guys,

I posted some years back about reviving an old Apple with keyboard problems. I finally got the thing to stop going crazy when powered on (repeating garbage characters even with keyboard unplugged) by reseating chips!
