#drdos — Public Fediverse posts

I just noticed that DR DOS 9.0 has been released a few days back!

By the creators of CP/M:

I have to check it out :)

#cpm #drdos

Siempre he sido muy fan de trabajar con comandos en #terminal en #macos, quizas una reminiscencia de mi historia trabajando con sistemas como #cpm, #vms, #appleDOS, #msdos (y sus variantes: #drdos, #pcdos, etc.), y mas recientemente #linux.

#homebrew es una de mis utilerias favoritas, y ahora ya alguien hizo un GUI muy practico para MacOS: https://github.com/Homebrew/brewui que es MUY facil de instalar y de usar.

I miss OS/2.

My first #Windows was #Win7 because I needed it for a required college course.

When I got my first PC, it was a Zenith running their version of #DOS.

I got a new computer and upgraded to #DRDOS (from #DigitalResearch) and #DesqView, which gave me #multitasking. I ran a #FidoNet #BBS for a few years.

When I got #internet, it was 128k #ISDN because I headed up support for the dialup #ISP I co-owned with a couple other guys. And I shut down the BBS. Somewhere in there, I'd upgraded to OS/2.

And, when #IBM gave up, I put #Debian on my desktop because we used it on the #servers at work.

When #DSL and #cable lured our 24/7 business customers away, we couldn't pivot to consumer internet before we had to close up.

So, I went to school for my associate's degree. And needed to take a #database course, which required #MSAccess, and so my PC was dual boot.

Until #Win10 was forced on me, and I removed the infestation.

I was getting tired of being a proactive #admin, and a friend suggested #LinuxMint.

That's my personal box now, and my school box has #Win11, but it's not actually my box — it belongs to the state.

DR-DOS está de volta.

DR-DOS Is Back, But Not Quite as We Knew It

DR-DOS 8.x, l'ultime version de DR-DOS.

DR-DOS 7.0.x, le DOS oublié

Hab mir grad mal für meine MS-DOS-Sammlung ein paar Bootdisketten für Partition Magic 8.0 erstellt und eingelagert. Funktioniert problemlos auf allerlei Konfigurationen!

Wer weiß, wofür man's nochmal braucht:

I've just done it only with mTCP and the Packet Driver. :0)

No Microsoft Network Client or Novell installed.

I run it this way:

#SvarDOS: DR-DOS is reborn as an open source operating system

Mein erstes Betriebssystem auf einem IBM-kompatiblen PC war übrigens DR DOS 3.41 - und ich bin dann auch bis DR DOS 6 dabei geblieben. MS DOS konnte mich nie wirklich überzeugen.

Nach DR DOS 6 stand für mich aber OS/2 im Fokus, und ich habe die weitere und verworrene Entwicklung von DR-DOS/OpenDOS 7.x unter Novell, Caldera, Lineo und DeviceLogics bzw. Udo Kuhnt (Enhanced DR-DOS) nicht mehr verfolgt.

Interessant war es für mich noch, DR DOS innerhalb von OS/2 zu verwenden, als virtuelle Maschine ("DOS von Diskette starten").

New binary release 20240914 of the EDR-DOS kernel is out. This release fixes a few boot and compatibility problems with original IBM-PC and with disks larger than 502 GiB.

https://github.com/SvarDOS/edrdos/releases/tag/v20240914

#DOS #DRDOS #EDRDOS

I today released a new version of the EDR-DOS kernel and command interpreter.

We made progress in preventing the EDR kernel from accessing uninitialized partitions.

This is an interesting one: DR-DOS shipped with a FDISK program which initialzed partitions with a file system right away, without the user having to FORMAT it. But because of this, the DR-DOS kernel never implemented proper filesystem validation.

The whole thing falls apart when using the EDR kernel with Free FDISK and NOT formatting a partition. Curiously, the kernel could then access the non-existing filesystem. But not anymore...

You can get it at https://github.com/SvarDOS/edrdos/releases/tag/r20240821

Anyone know of an #epub reader for #DOS?

A little update on my DRDOS kernel project: I managed to produce a single-file version of the kernel. It normally consists of DRBIO.SYS and DRDOS.SYS.

The name of the combined kernel is KERNEL.SYS and supports the FreeDOS load protocol (have to sort out a few minor bugs though). This means that it can be installed with the same SYS command as the FreeDOS kernel.

I finished porting the Enhanced #DRDOS source code to the #JWasm assembler. It can now be built solely with open source tools and under different operating systems than DOS.

In the near future I will regularly provide ready to go binary builds.

#DRDOS - Braucht das jemand von Euch? 5.0 ist nicht mehr ganz aktuell. Aber vielleicht kann man unkompliziert auf 7.0 updaten.

Recently finished a #floppy #archiving project, and found a few cool things: this Packard Bell DOS training program: https://archive.org/details/packard-bell-teach-yourself Copy II- PC for backing up software: https://archive.org/details/copy-iipc The companion disk for Customizing #DRDOS https://archive.org/details/dr-dos-companion-floppy #dos #digipres #525floppy

Fantastic to see DRDOS development still happening with this idle development http://www.os2museum.com/wp/idle-dr-dos/

@12thRITS I remember that a measure of skill in computer businesses was whether you were able to confidently edit the autoexec.bat. Incidentally all our batch files were kept in the c:/Belfry.

Oh I feel old.

@ElectricWill @Seraphyn People like to do this, because Microsoft isn‘t trustworthy. It has been a shady company and it is still one. #halloweenpapers #USVsMicrosoft #evilempire #netscape #drdos #predatorybehavior #antitrust #linux #appleMacintosh
