Great video for getting started in the hobby, good info on both emulation and real hardware! FYI, I swapped my ‘bad’ antic onto the new board, and the glitch came back. Looks like it’s probably something wrong with antic. I didn’t put the ‘good’ antic on the old board just in case the board itself is what caused it, like was mentioned. I live in the Wichita Kansas area, and I’m open to shipping it to someone for testing if they’re interested.

Great news, got the new processor board in today, and no more glitches! Even Rescue on Fractalus displays the mountains correctly now, so apparently that was the problem there too. Now that it's working right, I'm looking forward to diving into the thing, and seeing what it can do! Thank you all for your help with this, and let me know when you get your video ready, I'd love to check it out and learn some stuff. Also, should I try to do anything with the old ANTIC?

Thanks! No worries, I pretty much never throw anything away, it's a habit I got from my dad... On Pole Position and Frogger, the characters don't move at all, but on Blue Max while scrolling, they all shift one column to the left for a split second then go back, looks like they are flickering. I can try to run some other scrolling games to see what happens while I wait for parts. @Rybags I'd be glad to help out with something like that, but how would you recommend documenting/researching it? I'm pretty ignorant when it comes to the nuts and bolts of electronics, I'm a steel and hydraulics man by trade. -Rich

Thank you all for the responses! I had a feeling it might be something on the processor board, I just like to be methodical, and get other's opinions before I just start throwing parts at it ? I went ahead and ordered a good board from B&C. I'll let you know what happens when it gets here. @mclaneinc I am just using RF for video.

Hello all, this is my first post to this forum, but I've been reading and learning a lot here for quite a while, so thank you all for that! I'm pretty new to the A8 line, and finally got my first one, a plain 800, 48k, and 810 drive. Everything worked fine at first, then I noticed some games had a single column of triangles and random artifacts near the right side of the screen. Not every game did this. The ones I have that do are Pole Position, Frogger, and Blue Max (most obvious). Frogger is the hardest to notice, it shows up as "gaps" in the logs/turtles. I figured it might be some bad RAM, so I swapped out for known good RAM, and the problem on all games is still there. I've inspected pins, and re-seated every chip in the thing twice. My next guess would be either something on the OS board or the processor board, but I have zero experience and limited diagnostic tools. Not sure if it's related, but the mountains in Rescue on Fractalus are all sorts of messed up. Could just be a bad .atr file though... Just trying to get some expert opinions before I just start replacing every chip/board one at a time. I can take more pics if needed. Thanks in advance for advice anyone might have! -Rich
