Re: Acorn "POST box" display adaptor (0086,804)

Sounds like fun :-) I think a useful platform for this would be a Cypress PSoC 5LP eval board . The PSoC is a microcontroller with a small mixed-signal FPGA (it'll do programmable analogue stuff too): https://www.cypress.com/sites/default/files/media-embed/3128331/CY8CKIT_059__550.jpg This CY8CKIT-0...

Re: VLSI VY86PID development boards - Risc PC/Archimedes hybrid

Ah, I was poking around github and I noticed you were one of the people who had forked the Helios sources - and the only one who seemed to have committed very much to their fork. I can imagine the build system is... challenging. As it turns out, I do happen to have one of those GNOME Transputer Link...

Yep, there's loads of Active Book references in the Helios source code. And it appears to have run on Active Book hardware that looks roughly like the A5000.

VLSI VY86PID development boards - Risc PC/Archimedes hybrid

On my travels I happened upon this site: http://www.geekdot.com/helios-arm/ That's about Perihelion's HeliOS, an operating system originally designed for the INMOS Transputer platform but subsequently ported to other platforms, including ARM. Wikipedia suggests it was used for Hermann Hauser's Activ...

Re: Transputers and Xcore

I think it is feasible to hook this up to a BBC tube somehow, potentially rendering it the ultimate expandable überBeeb. :) So questions: Did anybody here do anything with transputers and what do you people think of the XMOS architecture? Funny you should mention that, because yesterday I was doing...

Re: A3010 hard disc interface

I was pointed at this thread, but until now haven't had a chance to comment. So apologies if this is a little late. If IDENTIFY is working for you, 90% of the interface is there. I'm afraid your board layout is very awkward for me to reverse engineer (it's better to draw a schematic first so people ...
