Re: Forth Day 2019

Hi All, My presentation on the Gigatron was well received at Forth Day here at Stanford University. I presented a Gigatron kit, to Forth Founder, Chuck Moore, in appreciation for his lifetime contributions to computer science. Another kit went to Andreas Wagner, an enthusiastic young Forther, who is...

Re: A Forth for Gigatron?

That sounds like it would be a bit more than a casual hack :D I would try to leave the ROM alone and that would keep things a lot simpler. From an awkward 8-bit Harvard machine, that has to handle video timing with careful instruction timing, you come up a level to vCPU, which is already a 16-bit ma...

Re: A Forth for Gigatron?

Hi Marcel, Thanks for the encouragement and useful advice. I have found a modern Forth for 6502 in Tali Forth which might be a suitable candidate. I'll be posting on the 6502.org forum to see if the project gains any traction. Like I said elsewhere, I'm going to be taking a couple of Gigatrons with ...

Re: Pluggy Reloaded

Hi Norgate, I'd be happy to give you a hand laying out the pcb. I have 10 years experience of EagleCAD - and this sounds like the sort of project that could be done using the (free) EagleCAD Lite version. I have also developed a very compact interpreted language called SIMPL, which is ideal for usin...

A Forth for Gigatron?

Forth is a programming language and computing environment developed by Charles H. Moore throughout the 1960s. It is ideal for resource limited computers and a means of being able to work directly on the machine without having to have be reliant on layers of unknown operating systems. In the 1970s it...

Re: Pluggy Reloaded

Hi Norgate, I recently came across a very low cost Arduino clone from Malaysia called the Maker UNO which has the advantage of Blue LEDs to show the state of all I/O pins and a small speaker on one of the I/O pins. https://www.robotshop.com/uk/cytron-maker-uno-microcontroller.html?gclid=Cj0KCQjwrrXt...

Re: Pluggy Reloaded

Hi Norgate, The ATmega328 will need a 16MHz crystal across pins 9 and 10 and 2 x 22pF capacitors to ground - in order to keep it fully compatible with the Arduino bootloader serial timing. The standard Arduino will accept interupts on Dig 2 and Dig 3 - make sure that you have these connected correct...
