During beta testing of The #ChambersBeneath, silentcrystaltears sent me this screenshot of the game running on an #ibmpc portable (model 5155). That gorgeous amber screen is a monochrome composite #cga CRT. #msdos

I just have released the schematics and PCB of my transputer board, along an article describing the process. Enjoy it! #retro #transputer #ibmpc #dos https://nanochess.org/transputer_board.html

My parents found an 'old' IBM PC (300GL series type 6285 with a 333 Mhz Celeron so 'old' is subjective) that I used as part of my "homelab" till the early 2000s.
Nothing groundbreaking, but still interesting:
* Slot 1 CPU
* Both ISA (3x) and PCI (3x) slots
* AGP (not slots, bus was for the onboard S3 Trio 3D video only, which however had a VRAM SO-DIMM expansion slot!)
* USB
The IBM design language at that time was also really nice. I remember the matching keyboards and mouse.
I don't think I'll keep it long-term, I'm just curious to see what 23-years-ago-me left on there.
It's pretty dirty. The floppy in the drive reads "Windows 98 boot disk" in my own handwriting.
Trying to find an old PC racing game, booter, #cga and when it started there was some digital speech from the beeper. Google sucks...
Any ideas? #retrogaming #ibmpc

I also remember backing up onto #floppy disks back in the day, but this has always been rather impractical.
The #IBMPC #XT had a 10MB #HDD and 360kB FDD, so with a 2:1 compression ratio, you'd need 15 disks to back the machine up.
This didn't change much in the early '90s. You had a 1440kB FDD, but you also had a 40MB HDD, so you'd need 14 floppies to back it up.
The introduction of USB HDDs, especially compact bus-powered ones, has *greatly* improved the #backup situation.
Star Cadre: Combat Class has a number of different items to help you succeed at your missions. Over the next several weeks I'll be posting about them. Visit http://dos.cyningstan.org.uk/downloads/261/star-cadre-combat-class to download the game. #starcadre #ibmpc #msdos #cga

ICYMI: The @internetarchive published my contribution to their "Vanishing Culture" report.

I focused on recovering lost software, particularly the games and experiments of the late cartoonist Yaakov Kirschen.
This has always been a bit confusing to me: The original Sim City "Graphics Pack 1 - Ancient Cities" was also known as "Architecture 2" in its European release. At the same time, it always contained the same three graphic themes: "Ancient Asia", "Medieval Times" and "Wild West".
Anyway: Here's a good European 5.25 360K inch disk set:

Nachdem mir letztens eine originale, deutsche Startdiskette für einen IBM PS/2 Modell 30-286er zugelaufen war, hab' ich sie gerade mal verwendet um einen solchen Rechner, emuliert in 86Box, einzurichten und zu booten.
Funktioniert wunderbar mit IBM DOS-Version 3.30!
Die bislang verschollenen deutschen Originaldisketten von Microsoft Windows/386 2.11 haben nun endlich ihren Weg ins Internet Archive gefunden. Insgesamt 7 x 720K DD Disketten. Ursprüngliche Veröffentlichung im Mai 1989!

Two big attacks against us in January push us down into 6th place. We have little in the way of gold, but are still a respectable force. Let's attack the 5th place barony to regain some land. http://dos.cyningstan.org.uk/downloads/64/the-anarchic-kingdom #anarchickingdom #ibmpc #msdos #cga

Our barony is nestled between the mountains and the sea. All the baronies are the same on the first turn, so our first attack will be arbitrary: the De La Poles have neither mountain nor sea, so they are the most foreign to us! http://dos.cyningstan.org.uk/downloads/64/the-anarchic-kingdom #anarchickingdom #ibmpc #msdos #cga
It's time for another playthrough of The Anarchic Kingdom. Whenever I play for stream or social media I do poorly, my first place finishes only happen when nobody can see. Can I change this? Watch this space over the coming weeks to find out... Get the game from http://dos.cyningstan.org.uk/downloads/64/the-anarchic-kingdom #anarchickingdom #ibmpc #msdos #cga
