@@flashjazzcat Last time I asked it was more of a legal-ish thing.

@@skabde Hi Steffen. Thanks for the interesting information. I didn't hear anything about these difficulties from Jurgen, but if it's indeed true that one must jump through such hoops, it's really disappointing. I personally loathe the hyper-regulation and bureaucracy which characterises the EU (at the commission and policy level; I have no problem with any citizen of EU member states, whatever their personal opinion of the EU), but regardless: it doesn't seem to do the hobbyist scene any good.
Hi, Bryan (UAV) here. The color invert option flips the polarity of the chroma carrier which has the effect of swapping the odd/even relationship of the NTSC artifact colors. The delay pot gives you a little control over the artifact color, but it's only useful to about the halfway point (clockwise). I typically set them to about the 10 o'clock position. I've found there to be a couple reasons for the NTSC jail bars, but the main one is many LCD TVs don't seem to do a good job of notching the 3.58MHz color signal out of the picture and the Atari's non-interlaced image without swinging burst gives you the worst case scenario for seeing it. On my favorite CRT monitor it doesn't show up at all. I've also seen chroma-luma crosstalk in multi-conductor cables make a difference.
Hi Bryan. Thanks for that information - very useful indeed. I found that the delay pot on my 800 affects the alignment of colour/luma, so you can ameliorate any 'fringing' at the left and right of - say - the blue area of the standard Graphics 0 display. As for the jailbars: part of this particular job is making the customer a nice Y/C cable, so we'll see if that makes any difference. On my own PAL SCCC 800 - using my daily driver video cable - the display is perfect, so NTSC definitely seems to impose some different demands on the cable/display. Thanks again for your comment.
@@flashjazzcat I've been out of the scene for a bit, but when I can get the time there's a few other things I'd like to put into a new UAV. It's always been my preference to try to work with the original machine video than go replacing everything with new hardware. Thanks for all your contributions to the platform as well.
Hi Jon, they say it never rains, but it pours, and clearly that is the case here. Hope the hand gets sorted, sounds like carpal tunnel, but I'm no Doctor. They will most likely do nerve conductive studies (joy of joys, electric shocks to the hand..Fun, fun, fun). Real life has a nasty habit of wrecking our hobbies, just this week I thought I'd killed a 130XE and managed to have my philips montor kill it's fly back transformer (on the way from Ireland at some point) as well as severe hassle from the DWP over my work pension. Good to see you back, even though it's stressful. Your vids are a joy to watch even though I have no wantings of a super colour card, the video is the bit I come for :) Keep well, keep safe, keep going!
Thanks Paul. Hassle from the council and social services regarding my mother and the ongoing nightmare of the aftermath of my dad's death definitely add extra spice to what is already a pretty flavourful situation, but such is life. Hope you get the monitor fixed.
@@flashjazzcat Sorry to hear Jon, councils and social services, two sets of people to inflame any situation. Re the monitor, part ordered from Southern Ireland, apparently it will take 2 weeks, must remember to drain any HV from the monitor, although I'm sure there's a chunky resistor to do that in there (8833 mk II). Stay safe and don't let the buggers grind you down..
@@Mclaneinc I have a flyback here for one of my CM8833-IIs (the dead one), but simply haven't gotten around to fitting it yet since the other one works (but could probably use a re-cap). I can't say I enjoy working on these things, bleeder resistor/manual discharge or not. :) And as for Social Services: a body of people whose efficiency and time/motion ratio goes through the roof the moment they sniff the care recipient's un-depleted assets!
@@flashjazzcat Yep, my old now passed friend Bob had the social services get involved because of his dementia, their first words "how much has he got in the bank", and then, has he got a next of kin followed by "if no one is in charge of his assets we are going to apply for to take them over.Have fun with the flyback, seems a pretty straightforward fix
@@Mclaneinc Especially aggravating when you consider how much we are already contributing to the Social Care budget via taxation (Council Tax, National Insurance, income tax).
Hey Jon, assuming I had the monitor to handle it, I guess you could wire up a switch on the NTSC/PAL jumper so that you could play your favorite PAL only games over here in NA?
@@Biker1bob When the jumper is in the PAL position, it uses the secondary crystal (which is redundant with NTSC) to drive the PAL colourburst pin of GTIA.
Glad to see new vid. So this thing basically takes multiple audio inputs (GTIA, SIO /tape/ audio and POKEY), and mixes them in some 'special' way to have cleaner overall sound. Since you didn't hear even GTIA clicks (and the chip is on the board itself), the problem isn't with the black cable, only somewhere between GTIA and monitor jack. Looks like busted amp or some kind of cabling issue. Scope to the rescue... (edit: unless GTIA sound isn't separated from other sources and grounding them mutes GTIA as well... the joys of deducing circuits...)
The console speaker wasn't connected (and GTIA isn't mixed in with monitor audio out on the 800), but it was the complete lack of SIO noise which alerted me to the fact there's no audio. Quite puzzling, but perhaps Jurgen will have some suggestions if I show him the video. I should look at the audio with the scope during the SIO polling sequence, as you say.
Question: I watched a video from YT channel that specializes in DCC and he kept saying "print" instead of PCB. I think he may be Dutch so maybe that's slang over there or maybe it's an industry or old way of saying PCB. Do you know?
Too bad you can't get this card here in Germany...
Well, that is puzzling. Does Jurgen not have any new stock yet?

Great video =D Love the Ukraine house painting and the intro - always wonderfully put together your videos!
Thanks man!
Hey Jon! Welcome back! Your videos are always a joy to watch! 👍
I'm also glad to see you here again, dear Jon!

Welcome back cat!
Hey Jon, assuming I had the monitor to handle it, I guess you could wire up a switch on the NTSC/PAL jumper so that you could play your favorite PAL only games over here in NA?
Unfortunately you won't get proper PAL/NTSC video wuthout PAL/NTSC ANTIC and GTIA chips. Just switching the video frequency isn't enough.
@@flashjazzcat ahhh ok, I did not understand that part, I assumed there was something in the board doing the conversion

Never heard that expression before, I have to admit.
That's probably a shortened form of the Dutch word "printplaat".
@@almerian Interesting - thank you!
Love the video. Keep it up
Thanks. Your machine gradually takes shape. :)
Great video! Get well...
Thanks!
I dont think you should ground both ends of the shield. it makes it a conductor vs. a drain.
