Apple II

I have a II plus keyboard that does not use individual switches. It looks like the top is moulded plastic with shafts on springs and a contact board underneath. I hope that's correct from what I see as I not see individual key switches. I have misbehaving rows of keys (according to the schematics). Some rows don't work and others "bounce" once or twice. I have contacted the person I bought it from, but if the are not helpful I will need to take it apart and check for shorts or misalignments. Can anyone share tips and tricks for this kind of keyboard.

Is there an ascertainable serial number or other unique identifying code for an Apple IIgs ROM 3's motherboard?

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
