The #LispMachine did away with the Endian problem just by being correct.

Ed now has 100 solved entries on RosettaCode, and most of them are mine 🥰 So yes, it’s possible to use antiquated editor and outdated regex format to solve quite a lot!

I found the person that solves tasks in ed in parallel to me! It’s https://rosettacode.org/wiki/User:Kennypete ! I’m not alone in my madness 😌

Hands Off the CFMEU! Protest the union busting laws pushed through by Labor. Join Socialist Alliance in Magan-djin (Brisbane), Gadigal Country (Sydney) or Naarm (Melbourne) this Tuesday or Wednesday.

Trying to get acme to have similar colors as my emacs. I think to learn how allocimagemix works

One of the most annoying aspects of CP/M as an OS is that it makes no assumptions about the terminal type in use; it assumes 7-bit ASCII stored in 8-bit machine words, and that's about it. It doesn't even assume the terminal is a serial one; it works just as well with something like the screen on the MSX.

Why is this annoying? Because it means every program that does more than just outputting raw text needs to be configured ("installed" in CP/M parlance) for your specific terminal.

This is where the Z-System comes in. It provides a "terminal capabilities" (termcap) system, which programs can target. A program "installed" to use the termcap system will work on any Z-System install regardless of terminal, so long as the termcap file for that terminal is installed in the Z-System.

For me, Sentinel 65X and RC2014 and SC500 and such things aren’t just “look at this cool retro thing!” (Which is also valid!).

They are as much a political statement as they are fun retro shenanigans. By building and using these things, we deny the big capitalists our money and attention, without which they cannot survive. Yes, we still give money to companies, but these are companies who want to sell us products, not sell us to others. Trade in and of itself is not the problem with capitalism.

Quite some years ago (2006-08), we brought the #OLPC AKA the 100$ laptop to Ethiopia as pilot. A surprising thing happened. The laptops were often without battery power in the morning. A thing that wasn’t anticipated. It had two reasons. One was the keyboard LED (it was removed in later series). It was used by the parents to have a light at home. The other was a bigger surprise. The parents used the mesh networking to discuss market prices for their produce. Fascinating. 1/8

I think I figured a possible implementation of a zero knowledge email server using open source software only

Writing a PoC

So, about my Z180 build. You've seen the front panel I'm making for it, very fancy -- but what will it have on the inside? Let's talk about it.

First, the general notion. It's not an #RC2014 system (which is no criticism of that platform, which I love and respect!). It's based on Small Computer Central's SC500 series of PCBs, which use the Z50Bus standard.

Most importantly, we start with the SC503. This pint sized powerhouse packs a Z180 CPU, an ~18MHz oscillator (the Z180 can internally double that if configured to!), 512KB of SRAM, and 512KB of flash ROM. It is configured to expose the two serial ports of the Z180, and it also has a built-in SPI bus port for an SD card, usable as internal fixed disk storage with CP/M.

The ROM firmware is provided by ROMWBW, which provides various iterations of CP/M, plus a machine language monitor, a BASIC, and the UCSD P-Machine, which is its own whole OS.
