I just picked up a 9" Sanyo B&W monitor (model VM4509) to use with my Apple II systems the "old school" way circa 1978. Looks great sitting atop the computer alongside my Disk II drives the way things used to be before affordable monitors came along.
However, I can only get it to display a stable image when hooked to my Enhanced IIe...when I plug it into my 1977 rev.0 II or 1979 II Plus systems the picture rolls like crazy and the V-Hold pot on the monitor can't get it under control.
Why would it be that it works really well with my IIe but not my II or II Plus?
I'm kind of bummed because it's the older systems that I'd want to use it with, not my IIe that has a nice Apple color monitor for regular use.
Any tips would be welcome, thanks!
