cognitivegears, 3 months ago in Remembering multi-tasking in MS-DOS: DESQView

I remember that well. We used DESQView to run our BBS as well. It was only a single line system, but DESQView let us do other things on the computer without taking down the board.

Has anyone played with TriDOS? github.com/prokushev/tridos - it doesn’t look nearly as featured, but has the advantage of being open-source and I thought might be interesting for a project I have in mind.

robocord, 10 months ago in Cores!

Back in middle school my friends and I bought an ancient computer from a bank, a Singer 5800, IIRC. It ran on 240v so we had to unplug the dryer to use it. It had a built-in seat, with the tty, processor, memory, paper tape reader, and printer kinda wrapping around the operator’s seat. It even had a little section you could flip down to bridge the last gap, leaving you totally surrounded. It was a hoot and a half going through the 5’ higher stack of manuals and learning how to use and program it. Inside the memory cabinet, where the 4K of core memory lived, someone had velcroed a horseshoe magnet to the door, with “delete utility” written on it.

Good times.

That’s awesome! I have a MicroVAX-II that hasn’t been powered up for about 20 years. I want to replace the power supplies and see if I can get it up and running at some point. Future project.

robocord, 10 months ago

MicroVAX-II was the first “real” computer I ever used, professionally. It started me down the VMS road in the late 1980s. I didn’t pick up the One True Religion of Unix until 1998.

Finally had to take VMS (and COBOL) off my resume about 15 years ago to stop all the calls from desperate headhunters trying to keep ancient systems on life support.

floofloof, 7 hours ago in Idle Windows XP and 2000 machines get infected with viruses within minutes of being exposed online — legacy OSes compromised by just connecting to the Internet

It’s nothing new. I remember doing this for fun about 16 years ago, putting a WinXP machine on the internet with no firewall and waiting. Even back then, it was immediately hammered by traffic and quickly started doing dubious things.

People already run windows 11 on core 2 duos.

Really amazing how people sink so much time into something like that. Port a super outdated CPU to a somewhat outdated OS. Why not? Well done.

BearOfaTime, 4 days ago in Idle Windows XP and 2000 machines get infected with viruses within minutes of being exposed online — legacy OSes compromised by just connecting to the Internet

Well, no shit.

This would likely happen to any machine directly exposed to the internet that hosts any kind of service intended for local networks only… (which is the network stack on Windows, and has been so since 1990 with NetBEUI/NetBIOS), and has been intentionally left insecured to boot.

Hell, in the 90’s we put windows desktops directly on the internet just to see what would happen (yea, our bosses would yell at us when they caught it). They didn’t get hacked much or very fast then, which shows how much automated intrusion scripting is happening today.

Bunch of clickbait nonsense.

Local machines aren’t servers. And servers aren’t directly exposed to the internet without routers/firewalls/IPS/IDS, etc. The only devices that should be directly connected to the internet are edge routers. And even they should have very secure, layered setups to ensure malicious traffic can’t transit to the LAN.

Peffse, 4 days ago in Idle Windows XP and 2000 machines get infected with viruses within minutes of being exposed online — legacy OSes compromised by just connecting to the Internet

I wonder how many people still directly connect to the internet without a gateway. It seems sensational to say “INSTANTLY INFECTED” and then tiny print (in a way that nobody connects to the internet since 1999). But maybe I’m just ignorant to how large a market still use direct connection.

brian, 4 days ago

The takeaway I think they were trying to give was that the same experiments done on a more modern OS does not have these same “instant” infections (they reference having windows 7 under the same conditions without any issue)

Peffse, 4 days ago

What are they going to write about next, the dangers of unsigned drivers and how easily they infect Windows 98? lol

TORFdot0, 3 days ago

I saw someone suggest they connect their switch dock directly to the internet elsewhere on Lemmy. Granted the attack surface for a switch is basically non existent but if people are suggesting that then certainly people are still connecting their other machines directly to their modems/CPEs as well

Peffse, 3 days ago

That would be Nintendo themselves. The fools recommend port forwarding everything to the Switch.

How to Set Up a Router’s Port Forwarding for a Nintendo Switch Console

cmnybo, 4 days ago

I doubt many people would do that. You would have to intentionally set it up that way. Residential ISPs almost always supply a modem with a built in router which will have a firewall. You would have to set it to bridge mode, enable the DMZ, or use your own modem.

I haven’t connected a computer directly to the internet since I used dial-up.

CosmicTurtle0, 4 days ago

I remember back in the days of broadband being brand new. Comcast insisted that you had to pay for each device that connected to the Internet. Using a router was considered against the TOS.

I do not miss those days.

ThatKomputerKat, 3 days ago

We had a router hooked up to our first RCA cable modem on Comcast, but then we were only comcast customers because they bought the company that originally hooked us up.

cable Companies though. Don’t miss cable internet at all. Fuck Comcast any decade.

paulh, 16 days ago in The BASIC programming language turns 60

I found that the simpler, early BASIC dialects were a good primer for assembly language. You had to create all the structure from jumps to numeric values. Goto and gosub mapped on to jump and call instructions.

Using labels in assembly was a step up from line numbers!

peron, 17 days ago in Trying to get DOS 6.22 on an SD Card, to then run via an ISA IDE to SD Adapter on my Commodore PC-10 III, but It doesn't wanna boot. What am I doing wrong?

DOS disk interface is quite mundante. It was dependant on BIOS recognition, and its not compatible with 32 GB disk at all. An 120MB or 250MB HDD was the usual MS-DOS disk sold during the 6.22 era. The firsts GB disk ware common by 1996. By the way, 2GB is the max recognizable partition size. Use fdisk to create a Master Boot Record, and a 2GB partition, and try it. I tried it with ease with old 1 GB and 512MB Compact Flash cards, but I must say CF has almost direct compatibility with IDE. SD cards require an adapter controller (you seems to have one of those, tho).
