RiscOS 4.02 - Aleph One AMD 5x86 133mhz PC Card Demo

This is a short demonstration video showing a rather unique ability of the Acorn Risc PC, released back in 1994. It had a second processor slot, which could accept a completely different processor architecture and yet still share system resources. The idea was to try and bridge the gap between Acorns operating system, and the already far more widespread Dos/Windows system. The irony is that we're now using more ARM processors than ever before, and at the very least your phone almost certainly has one in it. The differences between the two chips was stark, even then. The 233mhz StrongARM doesn't even have a heatsink, let alone a fan, while the guest 5x86 processor has both and generates the most heat in the system. The advantages for mobile platforms back then must have been very enticing... This video features the 233mhz StrongARM variant of the Risc PC, with RiscOS 4.02, released in 1996. The second processor card with an AMD 5x86 133mhz processor was added later on. I installed Dos, Windows 3.1 along with a few games. Here I run the software to boot the Pc side, quickly start Windows, then quit and run Heretic. Unfortunately the Dos sound is very shaky, and I've muted part of the video to save your ears. Apparently there are better sound drivers available, but I've not been able to locate them. There are various issues with the video other than the sound. My Vga-Hdmi converter cuts off the left side of the screen, and can't deal with the mode Heretic uses so it is squished! I was using the Vga-Hdmi adaptor, then a further adaptor to convert the signal to 1080p, to then further kick my GameCaptureHD's butt in to recognising the signal. There's also about 1 1/2 seconds of lag, making using the mouse difficult! Anyway it is what it is. At least it worked! Thanks for watching. :) Graeme
