Hm. I haven't really used 22" CRTs, but my father's old 20" CRT showed a similar purple/violet screen whenever it was switched on (this happened in the CRTs later lifetime). It was a cold solder joint, my father said. After a few minutes, the pciture was in full colour again. He also ran Win95 on …

Hello everyone, I'd like to ask you a favour.. Inspired by the unknown Compaq graphics hardware in this thread over here , I did a few tests with the Olivetti 640x400x1 graphics mode. It seems that Quick-Basic 4.5 does indeed support this mode. Now I wonder how many PC systems were compatible to …

Update. Because of a HDD failure (now fixed), my PC started up in diagnostics mode. The BIOS, as I found out, was quite sophisticated for its time (~85), comparable to the Super PC/Turbo XT BIOS. The built-in diagnositics "suite" is similar to CheckIt! or the later, menu-driven 286 BIOSes (keyboard …

I apologize, I have to confess a small mishap happened to me in my last capture. :( The neon sign was blinking and I didn't notice that it was in the wrong state. I'll do better next time. Speaking of the portable, I just found an old advertisement for the Compaq Portable 286. It's available at …

Who knows ? :) I guess without a sneak peek inside the portable, we can't be 100% certain. I also took some EGA screenshots with DOSBox. Please notice the vibrant, neon-like colours. The 3rd screenshot "graphics by" has a green tone that fits less to the OP's screenshot than the Composite screenshot …

Well, as Vile pointed out, Sierra made better use of Composite CGA. 😀 For comparison, I took a few screenshots (in DOSBox) with my father's copy of LSL1..:

That's a rescue disc just as I assumed. Well, yes, I guess so. But DOS/WfW can be installed from scratch, as well. The manual says: This is the instruction manual for your Operating System CD. This CD contains backup copies of MS-DOS (R) 6.22 and Windows(R) for Workgroups 3.11. Inside are complete …

Thanks for the feedback! My dad also liked the Trident 8900. Had one in his 386. I believe it either was a B or D revision. Anyway, the Trident 8900 never caused me any troubles and is also the official graphics card in DOSemu. What I like about it is its ability to switch to different video modes …

I also noticed …

The PAS16 should be able to handle circa 12MHz, since that was the speed of my 286. (It was dated/made '88, when CPU/FSB speeds often were still in sync with ISA).
