Those are well known boards:

* A Big Benny real time clock
* A 16kB ram extension board
* A bank switching from board (schakelkaart)

Nice Atom btw😀
Is documentation for these available anywhere? [-o<

Yes there is on acornatom.nl
Use the Atom Nieuws menu, then select Index AN and then op artikel. Use the browser search function to search your keywords like benny, schakelkaart or 16k etc.

Yep. Will do when I get a spare moment. It also contains 6502 second processor examples from my quick flick through.

An Atari 800! Sadly I cannot get any life out of it. I have a PSU that is supposedly compatible so I am assuming for the minute that it is.
When switched on I don’t get the power LED lighting up by the function keys. However when on a channel tuned into my 800XL it is obvious it is trying to do something - the screen goes from fuzzy to just blank (obviously I have tried tuning it :D ).

Anything simple I can try? I have removed and replaced all the plug in RAM modules etc.

Thanks for any help!

An AMX TPI-PRO-4...OK, not the TPI-PRO-DVI-4 I was expecting, but as I'll only be using the analogue inputs anyway, no problem. This model still allows the input of S-Video, Composite, Component and, of course, VGA. The ELO touchscreen I had already.

Saturday I should be getting my GBS8200, and then I can plug my BBC Master into one of the inputs. I then need to make up a cable to plug the Commodore 64, via S-Video, into another input. I've already written the code for the panel so I can get all four inputs on the screen at the same time. Touch one of the quadrants and it opens into full size. Touch again and it shrinks back down.

A C64 breadbin, a C64 breadbin motherboard, and a C128 trickled in over the last few weeks. All sold as untested and all unsurprisingly non-functional on arrival.

The C64 booted to a corrupt screen, had no cursor, no sound and two unresponsive keys. I cleaned the case, replaced both CIAs and the SID (sadly) with a NanoSID, fixed the restore and space keys, broke the shift lock key, fixed the shift lock key, changed the caps and fitted hitsinks and a lumafix. It's working nicely now. Finanically, this turned out not to be such a great purchase, but it was lots of fun trying to get it to work.

I bought the motherboard as a donor board. It was sold with all socketable chips (SID, VIC2, 7801) and the fuse removed and as untested. Originally, when I first tried it I got a black screen but it turned out to be a problem with the power switch. Once I'd cleaned the switch and popped in the missing chips it booted up.

The C128 also booted to a corrupt screen. However, this turned out to be just a loose character ROM which is seated on a flimsy little carrier board. This appears to be a factory mod present in the German C128s. Once I'd pushed it back in, the C128 started working, in both 128 and C64 modes. What a weird machine the C128 is. I'm really looking forward to playing around with it once it's been cleaned up.

I bought the deadtest cart to diagnose problems with all three machines but by the time it arrived I'd actually fixed everything.

I think I'm probably good now for Commodore 8 bit machines (although having said that there's another C128 arriving next week).

Nice, Retro mancave did a youtube video on these things, I seem to recall there are a few simple things you can do to minimise interference and get the best possible picture.

There's a fix with the NodeMCU that can get it running in a 50Hz mode which should solve most issues. It's on my "to try out" list:
https://github.com/ramapcsx2/gbs-control/wiki

The other fix that helps to get rid of sparklies is this one: viewtopic.php?t=13090

I am having some issues with an Atom and a Yarrb board (Atom goes into graphics mode after a second or so) and last Friday I wanted somebody to bring a scope so I could inspect some signals. He refused to bring it and I got really mad and pissed (is it allowed to say that here?). So in my anger I ordered a scope for myself and today I received this:

It is amazing how many hours you can lose playing with a scope, I just spent all evening trying to do an eye diagram of i2c comms, and failed miserably. Was more of a squashed mango diagram.

It’s astonishing how many hours disappear when playing with electronic components and circuits when you have a ‘scope to see what’s happening!

Good on you Roland =D>

Strangely enough I very recently got a scope too and it's first job was debugging a YARRB! :lol:

Now thankfully working fine.

BTW One of My ATOMS drops into graphics mode after a random amount of time when I connect in the TUBE I/F + MatchBox CoPro -- it also has a YARRB.

Would be good to know what solution your new scope reveals!

A rather nice out-of-the-blue gift. A Z180 kit with the CPU clocked at 18MHz. 512K ROM WBW, 512K ROM Monitor, 512K of RAM and a sprinkling of useful interface ports (serial, SD, USB etc). The homepage is here:

https://www.tindie.com/products/tindies ... board-kit/

All I have to do now is think of something to do with it. Modifying my FIF (Fif isn't FigForth) for it is a possibility.

The scope did not reveal much information. Although I saw that during one CS pulse of the 8255 there were two WR pulses. But that occurs also on a standard Atom without Yarrb. Perhaps a scope is not enough and I have to get the help of my logic analyser. I'll post in the Yarrb topic if I have any news about this.
