Re: And again a new Gigatron fan

Wow, lots of soldering! But I also enjoy soldering. My latest project was this one: https://www.tindie.com/products/kilpela ... r-arduino/

Soldering *and* weaving cores, fun!

And thanks so much for your offer to send PCBs to add to my 'shrine'! I'll send a DM.

Re: And again a new Gigatron fan

Hi Hans,

You made three of them right away? (Black, blue, orange)

Your wooden box is nice, nicely build.

Darn, now I want a blue and orange PCB for my collection of Gigatron stuff :)

Re: New Gigatron with 128K expansion. Boots from SD!

Nice to see this. Although I think putting SMD there is a bit cheating with the whole retro concept, I like how you've hidden that from view :)
Btw that's a nice DIP40 socket you have in there.

rC3 talk in German

Yesterday, there was a talk about the Gigatron at the CCC conference, which is this year remote, so named rC3. At https://media.ccc.de/v/rc3-703359-basteln_im_lockdown you will find the video. It's in German. They focus on the hardware and spend some time on how the logic gates work. The only softwa...

Re: Sell Gigatron?

Yes that can be done. You can also get rid of all the 0.1uF capacitors, on eevblog it was shown it will still work without them. That will give a bit more space. You could also use a simple crystal oscillator (saves a few components including U1) and a normal EPROM. We included an old-skool clock ci...

Re: Sell Gigatron?

Are the DIL packages actually still produces in Brazil? (Or maybe other South American countries?) It surely makes sense to source locally then.

Companies like JLCPCB are not very expensive for PCBs, but the PCBs are still a large investment if you want to do a small batch.

Re: Sell Gigatron?

Is SMD cheaper? Then that might indeed be an option. It will make it harder to solder though, or you'd have to have the PCB supplier do it for you, which takes away from the whole learning experience (but that might be a choice). Beware of the Asian suppliers as I already said.. it's fine if you mak...
