Retro Computers

We’ve already seen the marvels of the exciting Amiga PC in our previous Episode, but what about its Atari counterpart, which ran Atari TOS and the GEM GUI? The advertisements say you’ll have Power Without the Price, so let’s see if it’s true or not! Also in 🇮🇹

The Multimedia Revolution is here! Let’s have a look at the Amiga and its Workbench, which will give us the power to experience new ways of using a PC! Plus, it even has a GUI, couldn’t it be more wonderful? Well then, click the link below and connect to the magic!

Also in 🇮🇹

If you’re on the US East Coast, you should head on over to Wall, NJ and check out the Vintage Computer Festival East. After all, [Brian Kernighan] is going to be there. Yes, that [Brian Kernighan].

Events are actually well underway, and you’ve already missed the first few TRS-80 Color Computer programming workshops, but rest assured that they’re going on all weekend. If you’re from the other side of the retrocomputing fence, namely the C64 side, you’ve also got a lot to look forward to, because the theme this year is “The Sounds of Retro” which means that your favorite chiptune chips will be getting a workout.

[Tom Nardi] went to VCF East last year, so if you’re on the fence, just have a look at his writeup and you’ll probably hop in your car, or like us, wish you could. If when you do end up going, let us know how it was in the comments!

_readme.txt:

      Полное собрание сочинений для просмотра и реализации "Bit Tired demo 2025 by CSI" на БК-0011М

Архив содержит:

	disk - образ диска CSIDOS с демо

	bins - bin-файлы для заливки в CSIDOS, MKDOS, ANDOS (см. ниже).

	sources - исходные тексты демо.
	
!ВНИМАНИЕ! Для прослушивания музыки в демо необходимо наличие подключенных к БК0011М устройств:

		а) SMK512
		b) 2 x AY/YM - AZBK или GryphonSound или TurboSound

		При отсутствии этих устройств демо будет показано без звука :(

!ВНИМАНИЕ! Демо работает в CSIDOS, MKDOS и ANDOS! Универсальный загрузчик определяет свое местонахождение
(БК-0011, CSIDOS, MKDOS, ANDOS) и производит загрузку. Блок загрузки для MKDOS от Manwe/SandS, для ANDOS
от GRF. bin-файлы можно залить в одну из выше перечисленных ДОС и просто запустить .exe файл.

!ВНИМАНИЕ! Диск ANDOS, перед заливкой bin-файлов, необходимо дефрагментировать или просто подготовить
"чистый" диск.

!ВНИМАНИЕ! Демо работает и на "железе" и в эмуляторе. Выдержан хронометраж по музыке и по возможностям.


2025, Владимир 'KUVO' Кутяков, CSI

It's a widely known problem with roots in urban legend: Devices with motherboards failing in the early 2000s with a sudden pop, a gruesome spill, or sometimes a burst of flames. And it was allegedly all due to one guy who didn't copy a stolen formula correctly.

The "capacitor plague" of the early 2000s was real and fairly widespread among devices, even if the majority of those devices didn't go bad at the same time or even in the same year. The story of this widespread failure, passing between industry insider stories and media reports, had a specific culprit, but also a broad narrative about the shift from Japanese to Taiwanese manufacturers and about outsourcing generally.

The Asianometry channel on YouTube recently dug into the "capacitor plague" in a video that asks, "What happened to the capacitors in 2002?" and comes to some informed, broad, and layered answers. It explains the specifics of what's happening inside both a working capacitor and the faulty models, relays the reporting on the companies blamed and affected, and, crucially, puts the plague in the wider context of hotter chips, complex supply chains, counterfeits, and, sure, some industrial sabotage.

"We will never know what exactly happened, but let's try," the host says at the start. It is recommended you follow along.

For all the admirers of the SUN. There seem to be a few as I noticed by the comments on my previous post. There might be some to follow, I just have to export the right pics from shotwell...

ReadMe.txt:

Name: NAPTHA

An OoldSkool demo inspired by a live performance I attended and captured of "NAFT", a Belgian Live Analog Techno band.

The main song is based on "Paroxysm" by Naft.

Creator: Steffest
System: Amiga OCS
Runs on Amiga 500 with a 512kb memory expansion and beyond.
Amiga's with a harddisk can use the exe in the "harddisk" folder directly.

Released at RSYNC Demoparty 2025

Tools Used:

Graphics: 
Based on live footage from the band "NAFT"
Images where first sketched on paper and then produced in PhotoShop, including the Generative Fill tool, so I guess they are not AI free.
Images were finalized and pixel optimised in Dpaint.js: https://www.stef.be/dpaint/
Some chunky-pixel animations were taken from Giphy.

Music:
The main theme and some samples where lifted from the song "Paroxysm" by Naft using various stem-splitting tools.
The mod file was composed by hand using BassoonTracker: https://www.stef.be/bassoontracker/
The disk version of naphta uses a lower-quality compressed mod file to make it fit on a single disk and in 512k chip ram.

Code:
Home-cooked hardware banging C.
Compiled with SAS-C on the Amiga (but written in modern editors)
A big thanks to Wei-ju Wu for his YouTube series "Amiga Hardware Programming in C" which pointed me in a direction i could wrap my head around.
The blitter routines are heavily based on his examples.
Still bloody slow though... but boy, did I have fun.
Now I understand why everybody loves the Amiga Custom chips so much.

The Source Code for NAPTHA is available from https://github.com/steffest/naphta

Silicon Graphics Indigo 2 MIPS running IRIX. Quite a beast back in the days.

Don't forget to read the making-of for more details about the demo!

It’s time to resume our travels into GUI Wonderland, and go back to Apple’s garage to find out what happened to the Lisa’s younger sibling, the Macintosh, and its OS, called System! Is it a Lisa copycat, or are there any intriguing secrets behind it? Let’s find out!

I bought this computer along with some other 'stuff' - old CDs, AOL discs, SoundBlaster box from Circuit City....

The PS/2 is a model 25. The various stickers fell off of the interior while checking the disk connections. Ultimately the 20mb hdd was deemed a goner - I'm sure I could follow a guide to fix it, but instead I went with a CF card ISA adapter (CF uses ATA protocol - I didn't know this before my adventure!).

I ordered the 8087 co-processor along with the ISA adapter for the vast improvement it offered to Pac-Man. I highly recommend Monotech Vintage PC. It's a long shipping distance to the US but totally worth the wait.

I write on it using WordStar, a word processor I began using in 1989 or so when I had to write a state report on Indiana. Back then I was using an XT clone running CPM/80.

Radio Shack kit the wife got me for Christmas. STILL WORKS!
