#DOS

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

After a few weeks of procrastination, I finally took the time to read up on how to use EDLIN.COM. There's simply no way around it if you want to work with early versions of DOS from the 80s.

This here is me adding a few new lines to the AUTOEXEC.BAT of an IBM DOS 3.30. It ain't much, but it works! 😃

#QModem 4.51 #Source #Code release of an MS-DOS telecommunications program authored by John Friel III (1960–2024). This source snapshot reflects the state of QModem "Test-Drive" edition, version 4.51, as it existed in early 1992. The release is presented in the hope it may prove valuable as a historical artifact, for #telecommunications enthusiasts, retrocomputing hobbyists, or anyone interested in the inner workings of a classic #DOS comms package github.com/AaronFriel/qmodem-4

#retrocomputing question:

Is there any real mode Objective-C compiler for #DOS? I know about djgpp. Or any DOS compilers beside djgpp?

I don't need the NeXTstep / GNUstep / MacOS X library functions, just core language + classes.

Are the any DOS binaries for PObjC?

Thanks in advance. Please be so kind to boost!

Vintage AI vibes: A programmer ported the Llama 2 LLM to run on old DOS systems. Using a modified llama2.c, AI inference now works offline on machines from the 90s, albeit slowly. A fascinating weekend retro project.

I always wonder why Windows XP's title bar is blue. It was so bright, saturated. But compared to Windows 3.1, it looks like a modernized version of that legacy.

Ah yes, because who doesn't want to waste precious time resurrecting a 1991 game to unravel its "genius" protection—by making itself unwinnable? 🕹️🔍 is apparently the new productivity, because who needs a functioning game when you can have a PHD in failures? 🎿💾

Genial! Wenn Indy sich eine Weile in der Dunkelheit aufhält gewöhnen sich seine "Augen" oder unser Bildschirm an die Dunkelheit und Konturen werden sichtbar und der Generator tut dann sein übriges - wie es weitergeht seht ihr JETZT zusammen mit Wing Commander. #twitch #retro #stream #dos #indianajones #wingcommander

NetDrive with read-ahead caching, running on a VM to a local server and to a server 50ms away. A 4KB read-ahead cache results in a 3x speedup locally and nearly a 5x speedup on the remote server.

Real hardware results depend on the speed of the hardware. Slow machines don't benefit much when connected to local servers, but they still get the full benefit on remote connections.

#retrocomputing #DOS #mtcp

mTCP Netdrive read-ahead caching benchmark results.  A local server sees a 3x speedup using a 4KB cache, while a remote server sees nearly a 5x speedup.
