“Adrian’s Digital Basement ][”
In this retro hobby we’re all used to working with computers or hardware that’s already had a long life of use by a previous owner.

I think you can change some jumper settings but if I'm not mistaken that board you have to solder the pins in for the jumpers to change the CPU speed. Also you have to update the bios.
That laptop was one of the top of the line models. Very configurable for what itis. The CPU is under clocked so it doesn't have to have a fan for cooling.
The midi sounds like crap because the sound bank for the instruments is crap. The way to fix that is to update the sound bank for your MIDI. You have your mouse configured for DOS but not for Windows. And no the sound was always horrible on those things.
In early 1993 I was sitting in a EE lecture, when Marc Andreessen sat down in the row behind me with a chunky laptop, and showed off some new program called "Mosaic" to my lab partner. This stood out to me because laptops were not that common at the time, not because I had any clue who we were talking to.
iPhone pro has ability to stream in with custom colour balance, but you need an app that can do it. I'd fire feedback to the folks who wrote this app
That's super cool. I love the mid to late 90's laptops. They were so unique in many ways.
If I recall doom has gamma options. I think you have to run it in setup
The latch may have broken from being old. Old plastics can be fragile. Hell new plastics can be fragile. My work badge holder broke. So I bought a new one. In less than a month the new one broke, but in a different way. So I swapped parts since they were identical. It's still working now, but the latch on the new one just literally shattered. So it was defective for sure.
I still don't like laptops. The compromise is too much. They run too hot. My constant complaint is this is too hot. My PC on the other hand I rarely get the liquid cooler to go more than a couple degrees over ambient. And it does an amazing job at keeping the computer cool. I've never gone above 42 on the GPU and I think 75 on the CPU.
I'll bet that broken screen latch button was why that NOS machine was in that box. They discovered that and put it back in the box, but it was never returned to the OEM or distributor. HV power supply possibly at fault with dim screen. Marginal SMD caps?
for most things to work right on a laptop you really need the drivers, i had a laptop of the same era as this the sound was very quiet until the sound driver was installed, but then it was just ok
generic 90s laptop has crappy sound and video?….who would beleive it?…
i had a cheapo P5 something or other Win98 laptopcirce 98-99….put Debian Linux on it and it become much more useable
I love watching the repair videos of retro computers and CRTs.But to be honest in Germany with very high current costs that is a killing argument that one uses retro computers while there are emulations without the giant current costs. In Germany we have stupid politicans thinkink wind and solar is all we need and in emergency we buy french nuclear power so the price for current is 3 times as high as in US and i woud feel uncomfortabe run my old Amiga 1000 all day instead use WINUAE.
Put Debian Linux on it! I think that distro will still support Pentiums.
37:30 – on that note, a Compaq LTE 4/25 is a fairly strong and well built laptop.
By the late 90s though the laptops were comparable in performance to a 2-3 year old desktop. I have a Compaq Armada 1750 PII for portable retro gaming and it does that job fantastically – decent speakers, very nice screen, just plug in a PS/2 mouse and you've still got an hour per battery to play Settlers 2 Gold on your flight to the tropics. 😀
The display is probably lit by a cold cathode fluorescent tube. They can age and take a long while to reach full brightness
Hey Adrian. You're mentioning you're using NDI with your phone. Its slightly convoluted and will have a latency of 4 seconds or so. However if you can configure nginx with its rtmp module and host that on your pc. You can then use something like larix broadcaster to stream to that rtmp server and in tern get your capture onto obs. However it will have a delay, so idk if it'll be optimal for you. Why I mention this is because iirc larix has a ton of tuning features in it, like color and exposure etc.
As far as I can remember the screen being very dull on early (1990's) CCD color LCDs was normal. Color had only been available on LCD for a short while when that laptop was built. Also usual to have a very restricted viewing angle. TFT were definitely better than dual scan.
