The BBC Microcomputer System (or BBC Micro) was an innovative machine back in the early 1980’s. One feature that impressed reviewers was a “tube” interface that allowed the machine to become an I/O processor for an additional CPU. When the onboard 6502 became too slow, it could become a slave to a Z-80 or even an ARM processor. The bus was actually useful for any high-speed device, but its purpose was to add new processors, a feature Byte magazine called “innovative.”
[Hoglet67] has released a very interesting set of FPGA designs that allows a small board sporting a Xilinx Spartan 3 to add a 6502, a Z80, a 6809, or a PDP/11 to a BBC Micro via the tube interface. There’s something satisfying about a classic computer acting as an I/O slave to a fairly modern FPGA that implements an even older PDP/11.

[Daniel Bailey] built himself a scaled-down clone of a very early computer in an FPGA. Specifically, he wrote some VHDL code to describe the machine in question, a scaled-down clone of the Manchester Small-Scale Experimental Machine with an 8-bit processor and a whopping 8 bytes of RAM, all of which are displayed on an LED screen. Too cool.
That he can get it to do anything at all with such constraints amazes us. Watch him program it and put it through its paces in the video below the break.

The 16th annual Vintage Computer Festival Europa (VCFe) is still ongoing this weekend in Munich, and of course Hackaday had to swing by. If you’re anywhere in Germany, you’ve still got until Sunday at 16:30 to check it out.
The theme for this year’s festival is “The East is
Red Colorful” and that means vintage computers from the other side of the Iron Curtain. Here in (West) Germany, that naturally means a good representation of computers from the former Democratic Republic of Germany (DDR), but Czechoslovakia, Yugoslavia, and of course Russia were also in the house. There was far too much going on to cover it all, but here’s a few of the projects and computers that caught our eye.

Those of us that run Linux on a modern or nearly-modern PC know that it’s a capable operating system. It’s also (at least in my case with Ubuntu) extremely easy to install on a semi-modern computer. On a mid-90s era PowerMac 7200, things aren’t quite so simple.
In a testament to both his technical ability, and possibly even more so his tenacity, [Chris] was able to get Debian 6.07 running on a PowerMac destined for destruction. He had slated a few hours to upgrade this 56 Megabyte monster, but it turned out to be a several-day event. Those that are well-schooled in Linux may find the hairy details useful, and some more background can be found in part one. This project was a stepping-stone to something else, so we’re anxious to see what the end result is.
If you find this interesting, feel free to check out the retro edition of our site. It’s not entirely about ancient computers, but it can hopefully be displayed on one.
