retrocomputing

Years before Hi-MD, Sony took a stab at Mini Disc storage for computers with the MD Data format. I've covered the MDH-10 on LGR but completely missed the MDM-111 — until now! Let's install it, mess with DOS and Windows 3.x software, and run games from MiniDisc.

recreation of the default pixel font on the commodore C64.

this recreation includes most of the box drawing and block element characters, mapped to the equivalent unicode points. in addition, the checkerboard block elements have been mapped to U+2591, U+2592, and the U+25F0 – U+25F7 range.

in addition, the font has been slightly expanded to include the right and down arrow, and a handful of accented characters. apart from these, only the characters present in the computer's firmware have been included.

I had never heard of Lucas Deeco until working on these terminals. These two terminals are fascinating IP65 touch screen terminals for use in hostile environments. (Hostile to computers) Let's dig into what makes these tick and see if I can figure out why one of them is not working.

The Molar Mac is one of Apple's most short-lived (and ugly?) Macs, but perhaps real beauty comes from the inside. There's lots to explore with this obscure computer which came out during a crucial turning point in Apple's history!

It's time to get through more of the backlog of mail call packages!

This ISA video card doesn't work. There are no schematics so this is going to be an adventure to figure out why this card bad. Get your oscilloscope ready!
