gozar #1 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 Share this post Link to post Share on other sites
gozar #2 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 Share this post Link to post Share on other sites
gozar #3 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 Share this post Link to post Share on other sites
flashjazzcat #4 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 Share this post Link to post Share on other sites

Panther #8 Posted February 8, 2016 Aaaahhh! I was going nuts trying to figure out what was wrong. Damn mislabeled jumper! Quote Share this post Link to post Share on other sites
flashjazzcat #9 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 Share this post Link to post Share on other sites
Panther #10 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 Share this post Link to post Share on other sites
