Yes I had long forgotten how bad typing on this 400 keyboard is. Not helped by it bubbling due to a tiny split near the ":" . So are we concluding Antic has gone bad, and not RAM? I have a quote from "Best" for this one and one for my XL.

I have got a quote from Best (relatively painless process so far) for some 8bit items, notably my 2 x Antic chips that seem to have failed (plus a new 400 keyboard while I'm at it). His recommendation is to ship to a "freight forwarder" on the east coast USA, to then get cheaper postage to the UK. Sounds reasonable. I have found one forwarder (Stackry) which doesn't require a membership fee. Anyone done this and used this company? Or recommend another?

This... but, what we did when kids was - team up against the computer ninja guy, to make Bruce's life easier ... or more often than not in my case, make the Green Yamo stand there making that noise constantly

I will type the original program back in when I get chance, with a graphics character in line 40.

Antic buggered then?!

Ok. Just changed it. I think on that screen, the actual corrupt character still appears.... and again, in this new version, the corrupt character recurring down the right hand side -1 position. 20240415_141613000_iOS.MOV

Weird result with lots of corruption... 20240415_140104000_iOS.MOV

Donkey Kong is fine too.

I struggled to find an action game which didn't have corruption (Dropzone did, Fort Apocalypse did, Blue Max did) I tried Air Support which is vertically scrolling and this one looks ok:

The corruption remains in fixed position at the same column when the screen scrolls in Boulderdash. I am thinking Antic got damaged whilst diagnosing my 800xl

Not conent with my 800xl playing up, my 400 now decides to play up too.... although to be fair this may have always been an issue as I've barely used the machine since I bought it in 2015 as I have an 800 with Incongnito as main machine. Best described with pictures, some games have corruption at the right hand side of the screen. It actually stops Bruce Lee being playable as you can't exit the room! I thought it might be the version of the game, so I've tried a few different XEX and ATR's but all the same. Some games are unaffected, must be the certain graphics mode. What would this be, GTIA, ANTIC?

But .. this XL has the C014887, when I opened it up. Been working ok with it for years. When I was reading around this yesterday, it seems some early XL's had this version Antic and it was problematic. I think I may have to source an Antic, looking expensive
