... [SENSITIVE CONTENT]

I'm such a fraud. Here I am, spending several days getting my P70 and the OS/2 installation all shiny[1] and want to top it of with a little Office Space (the movie) reference.

And then I muck it up, by getting it mixed up with The Office (the TV series, which I haven't even seen btw!).

I only realised after I had shut it down and packed it away, so .. you'll all just have to forgive me one day. And Mr. Gervais was supposedly inspired by Office Space anyway, so...

Anyway, enjoy. Again a bit of NSFW so it's tagged as such..

    So I got myself a couple of IBM PS/2 model P70 386[1] luggable computers. I see they're quite the fad in some corners of the Retroverse, so I thought I'd pull my usual shenanigans and install OS/2 on one. I went with version 2.11 which is probably the most lightweight version, while also being really beautiful. I'll document my travails in this thread..

    Stay tuned, more to come!

        Welcome to my mini ISA VGA shootout!
        TL;DR: ISA Matrox cards are really, really slow in DOS.

        I recently built an original Pentium 60MHz system, built on an ECS motherboard. Around the same time I received a "mystery" VGA card: A Matrox MGA Impression ISA card. And since most of my builds are "open builds" and therefore easily accessible, that machine got the pleasure of becoming the test bench for the Matrox.

        As already revealed, the Matrox performs atrociously bad. So bad, in fact, that I had to test a couple other ISA cards to make sure it wasn't a system issue. I used my go-to benchmarking tool from Phil's DOS Benchmark Pack. I really don't want to experience Doom with this card..

        And without further ado, the contestants and their results in this spur-of-the-moment benchmark run:
        - Baseline: A 32-bit PCI S3 Virge/DX based card with 4MB RAM: A perfectly workable 48.2
        - The low-end Trident TVGA9000C with 512KB RAM (this is a real garbage card): A pretty shitty 14.2
        - The mid-range Cirrus Logic CL-GD-5422 with 1MB RAM (this is a decent card, know for compatibility but not necessarily speed): A barely bearable 24.7
        - And finally, the "star" of the show, the Matrox: A whopping 10.9!

        I said it was atrocious, didn't I? But hey, I'm gonna use this one with anyway, so who cares about DOS performance, right? ;)

            Was wondering why my /2 installation kept crashing randomly.

            Also, testing hashtags on snac ;)

            Memtest86 5.01 reporting loads of memory errors. Yay.

              Despite all the things IBM did right with OS/2, there were some absolutely mind-boggling decisions made. Today's example: Using Java (version 1.11 or better, mind you) and a Netscape browser plug-in to install TCP/IP. Other than the chicken-and-egg-problem (which is solved by installing the transport services - NIC and protocol drivers - first), there's the fact that they had a perfectly good software installation framework which ran fine on like 6-8MB of RAM (total!). This variant swaps until my CF card starts sweating with 16MB, and is s-l-o-w!

              I mean yeah, great, I get a proper BSD-4.4, 32-bit TCP/IP stack and tools. But it's taken me half a day. Getting the installation files over involved loading packet drivers and using in a DOS session. Which works .. surprisingly well. But still .. FixPak43, reboot. MPTS, reboot. Netscape 2.02, reboot. Java 1.18, reboot. Feature Installer plug-in (no reboot). Then, finally, TCP/IP.

              All this to have a machine to play with at .
