“Rodenticide” with the Seiko DPU414 Tape Printer.

The Seiko DPU414 is a small (110mm paper tape, ~90mm printable width) thermal printer, similar to the type used with cash registers everywhere, but slightly wider. It is quite unremarkable apart from the fact that no thermal printer of similar or greater width appears to be widely available; and also for the price (typically around [...]

Practical Lead to Gold Conversion; or an Intro to Opteron Resurrection.

It so happens that AMD resisted the informal NSA ban on the manufacture of LinuxBIOS-capable x86 CPUs slightly longer than Intel did. Or perhaps they were simply slower to succumb to Microsoft’s Fritz chip decree. Whichever may be the case, vintage (pre-2011, with some caveats, inquire within) AMD Opteron motherboards are a precious [...]

A Complete Pill for the Sage SmartProbe.

Note: Please read the FAQ!!!
The Sage SmartProbe was a very spiffy “Hard ICE” debugger, one of the few ever manufactured for use with modern (2010s) AMD x86-64 processors, and – as far as I’m aware – the only one ever sold on the mass market, rather than as part of “favourite son” deals (as, e.g., [...]

Mechanics of FLUXBABBITT.

The public discovery of FLUXBABBITT, a modestly-clever American spy gadget – that may or may not have been “fired in anger” yet – has provoked the usual flood of media garbage (“JTAG is a Chinese back door! Threat or menace?”) What follows is some basic investigation regarding the plausible workings of this device, based only [...]

Cardano Prototype Tidbits: TRNG Boards.

Cardano is a joint project of yours truly and Mircea Popescu. The objective: an inexpensive, user-auditable gadget which attempts to deal with the problem discussed in “Don’t Blame the Mice.” Refer to Mr. Popescu’s page for more details.
The device consists of a mainboard (not yet complete) to which two TRNG modules, containing two equivalent analog TRNG [...]

MicroWriter Redux.

I have decided to publish some of my “archaeological” work from last year on Cy Endfield’s MicroWriter.  The original objective was to produce a cycle-accurate emulator.  I do not currently have the free time to complete this project, so I will post my results here for anyone who might care to pick up the torch.

Engelbart’s Violin

Computing pioneer Alan Kay tells us that a computer is “an instrument whose music is ideas.” This seems like a beautiful metaphor, until you realize that we have somehow ended up in a world where the profession of musician is nearly unknown.  To continue with this analogy, let’s imagine that you were a [...]
