Re: Issue with building my own Pluppy McPlugface

More info on compatibility: https://en.wikipedia.org/wiki/PS/2_port#Conversion_between_PS/2_and_USB So you can use: - USB keyboard that also supports PS/2 (probable pre-2010) with any USB-PS/2 converter - USB keyboard that does not support PS/2 in combination with an active converter (post-2010) Pas...

Re: Issue with building my own Pluppy McPlugface

Thanks for your debugging work! Good to hear everything is now working fine. For some earlier kits, the cable is not the best quality. All the later kits have 28 AWG USB cables that work perfectly (either white or black). USB keyboard *should* support PS/2, but not all work according to specificatio...

Re: microtron

The RAM based ALU gives me mixed feelings. From the perspective of making a computer that they might have had in the late 70's, they would think you insane for using expensive ram to do math by LUT. On the other hand, once again. so much potential for interesting hacking. In 1K we have 4 LUT tables...

Re: microtron

Hi Steve, You have interesting thoughts, and it is nice to see them presented in such a concise way. I'm proud that the Gigatron has inspired you, in the same way designs before the Gigatron inspired us. I like how you have taken the design goals of the Gigatron and applied them, again, to the Gigat...

Didn't the eevBlog have red ones for the four-layer ones?
In de design phase, I believe you see some red stuff. But the 4L boards he made were green:

Re: My own PCB

I've now seen the original green, white, and black. I believe red, yellow and blue are the ones still not having been made :-)

Re: Gigatron ASIC?!?

Interesting stuff. I can imagine this is a project that will be a lot of fun to do and it would be very rewarding to have Gigatron ASICS. Is the goal just to learn about these systems and have fun while doing so, or do you see the resulting Gigatron ASIC as something others would be interested in? W...

Re: Puzzles - A gem matching+smashing game

It is not yet completely clear to me when gems disappear and when not.

If, say a double blue block is dropped and disappears as a result, and another double blue block is then dropped onto the empty "floor", it also disappears, which I think might be a bug?
