Re: 10MHz, 12.5MHz and Beyond!

I have the 15MHz version here. It has a different SRAM (AS7C256A-10JCN) that is not available in DIP28, so it uses a small SOJ-to-DIP adapter board. The ROM is a fast 27C1024 EEPROM (containing the special ROM v3y). CLK2 is not used, CLK1 is split off to CLK2. The caps (C1 and C2) in the pierce osci...

Read this if you need support building your Gigatron

A thousand enthusiasts have succesfully built the Gigatron kit that we sold in the period 2018-2020. We feel that all things that might possibly cause problems are well known by now. Mind you, there were only several tens of support requests for those kits, which we are very pleased with and is than...

Re: New games for the Gigatron

Nice to see new games emerging on the Gigatron! Marcel and I hoped the Giagtron would be mature enough to get a bit of a software ecosystem around it. That it also spawns a lot of ideas about Gigatron-like other systems is nice as well, of course, but I don't see them as a Gigatron, but as a separat...

Re: Expanding ROM space

That sounds like a security precaution to prevent files that are being uploaded from being run by the webserver.

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

Funny you should post this today. I also just soldered and installed the expansion today. I had to wait for a new programmer to arrive, I had a TL866 but that cannot program these GALs. So I got a TL866IIplus, but this turned out to be problematic.. I ordered in China, but made sure to use a seller ...

Re: Ye Olde Gigatron and Gigatronski

In my brain there is a connection between "ZIF socket" and "green". So although my eyes are working fine, I incorrectly called it green. It is aqua.

Re: Ye Olde Gigatron and Gigatronski

I had ordered some stuff for lb's expansion board. Instead of paying €20 for shipping, I decided to order some nice ZIF sockets to replace the big green ones, e.g. on Ye Olde Gigatron, so the shipping was free (or the ZIF sockets were free, depending how you look at it). First, getting the old one o...

Re: New vCPU instructions 2.0

Nice work. It's a lot of time these kind of things take, especially if you really think them through well, as you did.
