[Перевод] Прибытие IBM PC, часть 1

В начале 1980-х годов рынок персональных компьютеров представлял собой шумный базар, изобилующий разнообразием. У каждого отдельного типа персонального компьютера — от Atari, Radio Shack, Apple, Commodore, Texas Instruments и многих других — была своя собственная субкультура, состоящая из клубов и журналов, наполненных сторонниками, готовыми воспевать превосходство выбранных ими машин. [1] Хотя значительная клика мелких производителей, таких как North Star и Vector Graphic, поддерживала стандарт аппаратного обеспечения, совместимый с Altair (процессор, совместимый с 8080, и шина S-100), а также операционную систему CP/M Гэри Килдалла, их доля рынка была далека от монопольной. Стандарты в области графики, звука и подключения периферийных устройств различались ещё сильнее. Большинство микрокомпьютеров использовали процессоры, совместимые с Intel 8080 или MOS Technology 6502, но язык программирования BASIC был единственным практически универсальным « лингва франка », часто предустановленным в микросхемах постоянной памяти (ПЗУ) компьютера и обычно поставляемым компанией Microsoft.

With the latest 86Box beta version v6, I just took some time to re-create one of my favourite Compaq DeskPro 386/25 systems from the early 90s. This computer didn't have an integrated BIOS setup in its ROM, so I needed to use the appropriate configuration diskette. I'm installing IBM's PC DOS 5.02 as an operating system. This is perfect for running all these early DOS VGA games, like the original "Wing Commander".

Microsoft on taas kaivellut historiallisia arkistojaan

Nyt on julkaistu MS-DOSin "edeltäjän" varhaisia versioita, jotka löydettiin ainoastaan tulosteina ja digitoitiin jälkipolvien iloksi. 86-DOS:n ja PC-DOSin ensimmäiset versiot löytyvät nyt avoimena lähdekoodina GitHubista.

"Tippen wie der Großvater" :-)

Uff, das war jetzt hart: PC-DOS 1 wurde ja gerade zum 25-Jahre-Jubiläum freigegeben. Also DosboxX-Emulator, aber das dortige DOS aushebeln, PC-DOS 1 starten. Dann versucht, WordStar 3.3 (entspricht ungefähr der damaligen Zeit) zu installieren - nach 10 Versuchen gescheitert. Dann zum IBM-Editor gegriffen, Laufwerk A und B eingerichtet und nach weiteren 6 Versuchen - kawumm - läuft :-)

Pro-Tipp für Fans von Monkey Island:

Installiert ihr euch das Spiel in einer echten DOS-Umgebung oder einem PC-Emulator, denkt immer daran, die neueste Version der MONKEY.EXE zu verwenden. Interpreter Version 5.0.19 deaktiviert, ganz offiziell und ohne jeden Crack, den Kopierschutz und startet direkt in das Spiel. Außerdem wurden nebenbei auch noch ein Haufen Fehler und Abstürze behoben. 😉

A few more games to install on the Compaq Deskpro 386/25. These should definitely keep me busy for some time:

- SimFarm
- Flight Simulator 4.0
- Space Quest VGA
- Castle of the Winds

Retro gaming is still awesome in 2026! 😉

Ich weiß, es gab auch damals schon viel bessere Datei-Manager als die gute, alte DOS-Shell. Hab sie als Kind in MS-DOS 5.x/6.x aber wohl so oft verwendet, dass ich in DOS einfach nichts anderes benutzen mag. Und die DOSSHELL Version in PC DOS 2000 ist sogar noch ein bisschen weiterentwickelt. Also ich oute mich mal als Fan! 😉

Es hat mich tatsächlich über ein Jahr beschäftigt, aber ab sofort ist das IBM Betriebssystem PC DOS 2000 mit vollständigem, deutschem Handbuch komplett im Internet Archive abrufbar. Das sind insgesamt 686 Seiten in 300dpi, sauber gescannt und digital restauriert.

Bei PC DOS 2000 handelte es sich um die letzte offizielle Vollversion von DOS aus dem Jahre 1998, bereits mit sämtlichen Y2K Updates. Voll kompatibel zu Windows 3.x und Spielen für MS-DOS!

Puuh, eines meiner größten Scan-Projekte nähert sich nach über einem Jahr Arbeit nun unmittelbar der Fertigstellung. Stand heute Nacht sind nur noch ein paar wenige Seiten zu restaurieren für das große, fast 700 Seiten starke, deutsche Handbuch von IBM's PC-DOS 2000.

IBM DOS 3.30 is surprisingly capable, but unfortunately it only supports partition sizes of up to 32MB. This is annoying!

I'm trying to figure out the best DOS configuration for emulation and maybe real hardware, too. Right now, I am considering IBM DOS 5.02 upgraded to PC DOS 7 Rev. 1 (2000). You get an IBM branded DOS-Editor, but still all the nice tools from the future, like DELTREE.EXE, DEFRAG, PC DOS-Shell 7.0 or Windows Undelete. Seems to be the best overall DOS package...

Any other ideas / suggestions?

I finally managed to install a working graphics driver for the TRIDENT 8900D within my new 86Box VM. This is running in a beautiful 800x600 resolution with 256 colors. Classic!

In case you're wondering about this file manager: Yes, it doesn't have toolbars. No, it's not broken. This is normal. You're looking at the good old Windows 3.1, not WfW 3.11! I just love these subtle differences!

Something I just discovered today:

When I am running Microsoft's ScanDisk (from MS-DOS 6.22) on top of PC-DOS 7, it gives me this rather bizarre warning message addressing a possible issue with long files names. Somehow, in 1994, it already possessed some pre-emptive knowledge about the upcoming MS-DOS 7, a.k.a. Windows 95, which would introduce long file names. Interesting!

Kleines Update zum "PC-DOS 2000" Handbuch:

Nach etwas mehr als 400 fertig eingescannten und digital aufbereiteten Seiten hatte ich vorhin mal testweise eine 150dpi PDF-Datei ins Internet Archive geladen. Wollte mir nur mal vorab anschauen, wie das Ganze im dortigen Buch-Lesemodus angezeigt wird. Das Ergebnis gefällt mir eigentlich echt super und das freut mich wirklich! Alle Seiten sind gerade und super lesbar und auch von der Optik her so, wie ich es haben will.

Ich arbeite ja schon mehr oder weniger ein halbes Jahr an den Scans. Seit September 2024. Uff... jetzt sind "nur" noch 276 Seiten übrig! Irgendwann wird es fertig werden.

Today, I was finally able to complete my collection of PC DOS 2000 boxes, at least for the German versions. I unpacked the CD-ROM Edition from 1998, which seems to be a bit smaller than its 3.5" floppy disk variant.

By the way: The CD-ROM includes a complete set of floppy disk images, which makes it even more an awesome collector's item!

@brettcannon considering that's it's basically a file with no name and only an extension... #PCDOS

Look, it's a game! (kind of!)

#cprogramming #gamedev #retrogamedev #msdos #pcdos #freedos #retrogaming

My next step with the game was building a workflow for taking the spritesheet and turning it into assembler. Writing image bytes directly using unrolled assembler on older PCs is way faster than copying pixels in sets of (x,y) loops, especially when transparency comes into play. And this speed up is just from the arena tiles! Once the characters and shots are using assembler, it'll be even faster.

I wrote Ruby code that reads the spritesheet image and a YAML config file, and builds Open Watcom Assembler-friendly sprites & a C include header so I can call the sprites easily. Not only did I learn a lot about assembler and using it with C, I also learned about C calling conventions and how to get those working well.

Next is collision detection between objects, which will require tweaking the Ruby code to make it nice, and then I can get on with the actual game part of all this.

Making progress on my DOS game! The character's target cursor tracks the mouse pointer. They can fire by holding down the mouse button, but they can only have 12 shots on screen at once. I also improved the structure of the dirty rendering code in anticipation of having to redo it anyway once I have many many more things on the screen and need to actually deal with performance issues.

I finally figured out how to effectively use the Sound Blaster! I managed to wrap my head around the DMA and DSP APIs, collapse all that down into a handful of structs and functions, and get (pretty much) clickless playback of fairly long 11KHz 8 bit PCM files working with a sub-4K buffer on an emulated 386DX-33.

Continuing on my PC programming adventure, I got the following working in C:

* 256 color BMP file loading
* Unchained Mode 13h 320x200 graphics
* Double buffered graphics
* Mouse and keyboard reading
* "Sprite" rendering across unchained VGA planes

Next will be reading from sprite sheets and sound programming, then I'll make a little game out of all of this!

DOS 6.3, 0.08 better than DOS 6.22

I believe this is post IBM/Microsoft split so I'm curious to see how different it feels.

This video gives an in-depth look at what is currently the oldest known copy of 86-DOS, the antecedent to #MSDOS aka #PCDOS, where we go through the process of moving from CP/M, translating Z80 to 8086 code, and assembling it. Since this DOS predates the IBM PC, it must be simulated via #SIMH as a Gazelle with a Cromemco 4FDC controller. #retrocomputing https://youtu.be/Zd7T5euID1E
