The Care and Feeding of the Sage SmartProbe.

Note: Please read the FAQ!!!
If you cured your Sage SmartProbe of its congenital disease as per the last article on the subject, you may now be wondering what to do with it.
The vendor supplied a massive Java shitware with the thing, which does not merit any discussion whatsoever. Instead, we will use the probe’s very [...]

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., [...]

Terraforming the “MyCloud Mini” : TTY.

“MyCloud Mini” is a ~$50, dual-core ARM, 256M RAM, 256M Flash, dual SATA box, in various respects similar to the famous PogoPlug.

Use a standard (e.g., CP1202) TTL converter. And you will get:

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 [...]

Household Tips: Reviving a Dead Laser Cutter.

Not long ago, I happened to come across a very cheap and heavily used CO2 Laser Cutting Machine, made by Full Spectrum Inc. About 1K USD, including curbside delivery from across the continent.  I also bought the traditional water chiller, air compressor, exhaust manifolds, etc:

The junk seller promised an intact tube, and indeed there was:
Naturally, [...]

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.

Stierlitz Example: Memory-Mapped I/O to a Character LCD

Here is a somewhat dumb example of the kind of thing one can do with Stierlitz.  Let’s say that you have some memory-mapped I/O ports in your system architecture, which you would like to test without having a working CPU design of any kind loaded into your FPGA.
The Xilinx ML501 board includes a Tianma-TM162, which [...]

Stierlitz, the Fearless, Driver-Less Bus Analyzer.

The tool described in this post may be helpful to other ab initio machine-architecture developers.  If any exist.  The rest of Loper will remain in my private code repository, because it is not a collaborative project.
Meet Stierlitz [1], perhaps the world’s strangest bus analyzer.  For basic use, it requires no software at all on the [...]

Cypress EZ-Host Firmware Development Under Linux.

Progress has been slow, because I have been otherwise occupied for quite some time.  Slow, but not entirely still.
Since turning Loper OS into an ab initio CPU architecture project, I have been using Xilinx development boards for prototyping.  For the past year —  an ML-501.  The FPGA toolchain itself is (grudgingly) Linux-friendly, but those for [...]
