I can't say I'm wild about a world where Digital Research won. When they were dominant with CP/M, the tools and documentation were bad to the point where most machines had Z80 processors and DR only provided an 8080 assembler, so you had to DB significant bits of code to get the missing opcodes. Developing RSXs to access bank-switched memory under CP/M 3 could have been so much easier with a few examples and perhaps…

DR-DOS 5 was alright and Viewmax a nice way to manage files and directories.

I remember using a Z80 assembler on a CP/M 1.x machine, way back when. If it wasn't by DRI could it possibly have been (shock, horror) Microsoft??? We did have a Microsoft Fortran compiler, which was crap, but that was mostly down to being floppy disk based. Not trying to be funny, I used the assembler a lot, but I really can't remember who supplied it. Oh, just had a thought - this was on Research Machines 380Zs, so…

Yes, there were one or two third party assemblers available. From memory, the issue was with the downstream tools - so for instance on CP/M 3.0, I think you had to use the DR one to be able to build an RSX (equivalent of a TSR under DOS. You could count the number of 8080 CP/M 3.0 machines on the fingers of one foot.

You've reminded me that I have a 380Z or 480Z in the loft - I must get it going again.

DR-DOS was more than alright, if Microsoft hadn't smothered it the computing world would look very very different today …

I'm sure this is a mostly forgotten part of computing lore; apologies for the Gemini's Overview:

“Microsoft actively stifled DR-DOS in the early 1990s through anti-competitive tactics, primarily using the "AARD code" in Windows 3.1, which deliberately created compatibility errors to scare users away from the competing operating system. Microsoft also used FUD (fear, uncertainty, and doubt) tactics, such as hinting at future incompatibilities.

Key Tactics Used by Microsoft:

    The AARD Code: Windows 3.1 installer contained heavily obfuscated code, discovered in 1992, that specifically checked if the system was running DR-DOS. If detected, it displayed a fake "Non-Fatal Error" message to induce panic.

    Vaporware Announcements: Microsoft announced upcoming versions of MS-DOS to dampen demand for current versions of DR-DOS.

    OEM Pressure: Microsoft leveraged its monopoly to ensure pre-installed Windows came with MS-DOS, hindering DR-DOS's retail market success.
While Digital Research released a patch (the "business update") to bypass the AARD code, the damage to market perception and OEM deals was significant. The case was later part of legal battles between Caldera (which acquired DR-DOS) and Microsoft.”

GEM on the PC was... ick... compared to on the Atari ST. But the problem with GEM on the Atari ST is that in order to cram it into the 192KB ROM they ripped out some goodies like proportional font support which ended up being in an add-on called "GDOS" which was buggy, used up RAM, and most people didn't have it (it came with things like DTP software etc). In general this was always the problem with the ST. The Trami…

Wow, I just remembered using AES when I wrote an 'accessory' (menu bar app) that converted bitmap to vector for an ST DTP app that supported both. An early form of plugin I suppose. Pretty ahead of the MS mess at the time.

Apple sued DRI, which resulted in the crippling of GEM, the glaring one I remember were static windows. You heard that right, windows were not resizable but had fixed screen locations in the PC version. Thankfully Atari licensed GEM for their 68000 machines before the lawsuit, and wasn't affected by these changes. The Atari ST (Sixteen/Thirtytwo) was very Mac like at the time. It even ran the Mac OS from Apple ROMs (…

Windows were only fixed in the desktop application, you could still move and resize them in your own apps.

Didn't know, thanks for pointing that out. Never used GEM outside Atari, just something I read at the time.

Earlier quoted context omitted.

Dongles were a thing, certainly the expensive MIDI programs used them. Cubase, Steinberg and C-LAB Creator were the big ones. As I recall, there were tons of books about GEM for the Atari ST, at least in Europe.

Man I spent hours and hours just last month trying to reverse engineer the original Notator/Creator dongle and get Notator to launch in emulation by patching Hatari to emulate the dongle. Codex & Gemini & I had something almost working. That dongle was evil and crazy complex. Fairly complex CPLD that depended on system timing and in the end the emulator just can't fulfill whatever contract the software expects from t…

Is the software still attractive to use, after all those years, or why are you going to these extremes? Sounds it's somehow intimately intertwined with the dongle, if the check routines can't simply be patched.

> But the bigger problem was software piracy. Piracy was common on the ST, and that made developers less enthusiastic to continue ST development Not so sure about this. The Atari/GEM combination was very popular with musicians for MIDI, and I don't think there was so much piracy, or at least not compared with other platforms of the time. The reasons I didn't develop anything much for Gem - a) It was quite difficult b…

I got all the GEM docs through Archie at umich.edu. You could get everything there including the entire GNU toolchain and MiNT so you could have a real development environment.

Between DM sessions, of course. Or Time Bandits.

How much was an Atari plus Spectre/Aladin?

The problem was you also needed to buy a Mac to get the licensed ROMs.

Going down this rabbit hole, I realize that ST hardware for musicians is still huge. And the dongles as still working as intended, apparently.

And then this blew my mind:

The dongle has already been reverse engineered in the last couple of years and replicas are for sale.

Yes I am aware of this, and read the HDL to understand what they did. But they are hardware only. The point is to run in emulation.
