gozar Posted September 9, 2015 Share Posted September 9, 2015 I'm slowly working through my VBXE install in an 800XL. I have it installed I think, and when I turn it on, the machine works and I have a picture (just composite for now). Unfortunately, it's in black and white. Where do I start troubleshooting? Here's a pic of the install (large picture!): Quote Link to comment Share on other sites More sharing options...
gozar Posted September 9, 2015 Author Share Posted September 9, 2015 False alarm, joey_z pointed out it could be the PAL/NTSC jumper... I could have sworn I put it on NTSC before I installed it... :-( 1 Quote Link to comment Share on other sites More sharing options...
gozar Posted September 9, 2015 Author Share Posted September 9, 2015 Ugh, it appears to be working, except its a little flakey. When I start up fc.com to flash, B1 is blank. It doesnt say (empty), there is nothing there. I also can't set the FX Rambo core aa the default. The screen shows Bootbank: - I switch to the bank, hit B, then hit X. If I don't turn it off it boots that core. And, any try at flashing any bank results in VBXE IO error. Where ahould i start? Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted September 9, 2015 Share Posted September 9, 2015 PAL/NTSC jumpers are labelled the wrong way on the board - at least they are on all boards I've had through my hands. This may be relevant here. Quote Link to comment Share on other sites More sharing options...

Panther Posted February 8, 2016 Share Posted February 8, 2016 Aaaahhh! I was going nuts trying to figure out what was wrong. Damn mislabeled jumper! Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted February 8, 2016 Share Posted February 8, 2016 All the recent boards appear to have the oscillators in the reverse positions, so are now correct. Only way to be sure is to inspect the components themselves. Quote Link to comment Share on other sites More sharing options...
Panther Posted February 9, 2016 Share Posted February 9, 2016 I took a little while to get around to installing it, so yeah, my oscillators were reversed. Hate it when that happens. Quote Link to comment Share on other sites More sharing options...
