Comparing the Z80 and 6502 to Their Relatives
Last week’s adventures with the Exidy Sorcerer led me to write a Z80 version of the LZ4 decompressor I’d previously used on the SNES, the CoCo, and the Genesis. At this point, this has …

Remarkable Pro Colors
I was happy with the Remarkable 2 and when the Remarkable Pro came out I decided to go with a second one in order to be able to see two pages at once : one as a reference for reading and one for writing, as one would normally do with paper. Expensive approach, I know.

A few CPU hardware bugs
Catherine (Whitequark)’s recent observations on poorly-engineered firmware reminded me of a few mistakes I’ve seen in vendors’ CPUs; some unimportant and others surprisingly bad. Since I’ve never seen these widely discussed, here’s some discussion and links to supporting evidence to make them more widely known, since…

A Year of 3D Printing
If you'd asked me a few years back if I thought I'd buy a 3D printer, I would have said no. My experience of 3D printers back when I was in college was that they were very slow, expensive, frequently failed mid-print, and needed constant calibration...
