A Very 2017 Take On A BBC Micro

In the early 1980s, there were a plethora of 8-bit microcomputers on the market, and the chances are that if you were interested in such things you belonged to one of the different tribes of enthusiasts for a particular manufacturer’s product. If you are British though there is likely to be one machine that will provide a common frame of reference for owners of all machines of that era: The Acorn BBC Microcomputer which was ubiquitous in the nation’s schools. This 6502-driven machine is remembered today as the progenitor and host of the first ARM processors, but at the time …read more

Retrocomputing With Open Source FPGAs

A few years ago, we saw the reverse engineering of the Lattice iCE40 bitstream, opening the door to a completely Open Source development tool chain for FPGAs. This was an astonishing amount of work from [Clifford Wolf], [Mathias Lasser], and [Cotton Seed], but since then we haven’t seen a whole lot from Project IceStorm. Now, that’s about to change, and in the coolest way possible. [hoglet] is retrocomputing on an ICE40 development board.

This is an implementation of the Acorn Atom on a myStorm BlackIce board. This board is basically just a Lattice iCE40 FPGA, a few support components, and …read more
