CapsLock revisited
I've added a Caps Lock LED to my Atom and thought I'd share my happiness, at last an LED on the outside. 20200525_212855.jpg 20200525_212838.jpg I used a16v8 in the now empty IC51 socket after I upgraded my memory with a YARRB. IC51 obviously has all the right signals as the caps lock mask is stored...

Re: Replacement power jack for Atom
Risking the wrath of the Retro Gods (Please
don't send the plague of @'s).
I've just noticed this Cypress dev kit on RS, Its expensive for a barrel connector replacement: £22, but it may be worth having a look at.

Re: Atom GODIL VGA Adapter
Thanks Dave, All looks good except for: 20200514_141340[1].jpg This looks like a decoding problem and may be an address line (A11?) stuck probably something to do with my brutalisation of the Godil in removing the IDC connectorss. It does draw the top bit before overwriting it. I'll go in and look f...

Re: Yarrb - redesigned
You can ask Sir Morris if he has AtoMMC boards available. I don't have any left. @SirMorris, Do you have an ATOMMC board left, I am trying to see if I can adapt your PIC code to run on a cypress psoc6 ARM dev board via the sk8 and using SDDOS/ATOMMC rom, cy8ckitproto.jpg but it would obviously be a...

Re: Today I built ...
(That's assuming your adapter maintains the original GODIL pinout) Yes it does, took it from the original schematic. Thanks ! I've just purchased one of the idc GODILs and a 40 pin smd dil adaptor. I thought I would remove the IDCs and solder on the dip but It probably would be less damaging to the...

Re: 3D print Acorn Atom case
Did anyone try printing the issue 4 Keycaps and has the design/dimensions as a model? I have a missing ;+ key and given their scarcity I'm thinking that I could get it printed on a fancy 3d printer at work (whenever they call us back in), but I don't want to risk too much damage pulling one of the g...

Re: Yarrb - redesigned
Hi Roland,
Do you have any of the YARRB2 boards left? If not are you planning to order more? Although my atom is up and running now the Timedata 32k board gets quite toasty and I feel the need to cool the system down a bit.
Also is it still possible to get the atommc/sddos boards?
Thanks in hope

Thanks for the warm welcome https://stardot.org.uk/forums/viewtopic.php?f=13&t=19092 , I've been going through the circuit schematic and comparing it to my atom. I have accounted for most of my mods. Like most things you make changes over a period of time and some of the changes you made a while...

Hello From Cornwall
HI, I've just dug my Atom out of the loft and am now in the process of trying to figure out what all the mods I inflicted on it actually do so that I can start to think about getting it working again. I have lots of tapes to convert. The Atom was one of the first lot from Acorn and was a self built ...
