Hello fellow retro enthusiast, I'm a VC collector from Australia.
A couple of months ago I acquired an NTSC Apple II Plus, and just recently I acquired an NTSC Applecolor IIe composite monitor. The Plus works great, I've installed a Microsoft Ram card and Softcard in it as well as a super serial II and disk II controller. Everything works great except for the color output.
I originally had some issues with the video output, the text was very faint and picture geometry was out of whack. But due to reading some posts on this forum, I managed to adjust the picture using the blue trim control on the motherboard. I now have very bright text and geometry is perfect, but still no color.
Things I've tried to troubleshoot the color:
1) I've tested that the monitor can display color using a DVD player and the monitor displays color fine.
2) I've adjusted all controls on the monitor and motherboard such as the color trim to no avail.
3) I replaced the crystal on the motherboard with a Fox 14.31818Mhz crystal, no change with the color.
The motherboard on the Plus is a pre-RFI, I think revision 0 board. Something curious that I noticed, it has a 2716 eprom installed at the front on the motherboard in the ROM SPCL slot with a label on it saying VIDEX LC Chip 1st Ed.?
Is there anything else I can do to get the color working, any help would be appreciated?
