Let's Code MS DOS 0x1D: Melting the VGA Screen

One of the effects that is easy to do on machines like the C64 or Amiga is the „melting screen“. In theory you can do such things just by copying lots of pixels in video memory. However the VGA is rather slow for doing that. So what we will do instead is cleverly manipulating the CRTC registers of the VGA to achieve a similar effect. This lets us move big portions of the screen without actually copying any bytes.

Hey long time no vid good to see you back!

Yes, quite a lot of other things on my hands, plus the ET4000W32i isn't working yet. But I will pick up speed in a couple of weeks when things have settled down again. 😀

Plus I only announce MS DOS / PC related content here, but there were some non-PC things, like 1541 repair, 2600Jr mod etc...

I follow your Commodore related content 😀

I miss watching you solder stuff though, they are hypnotizing and encourage me to try different DIY projects myself. Cheers.

Let's Code x86 Assembly: 0x01 Hello World

In my Let’s Code MS-DOS series we already did a little bit of assembly language. However I think it is more fitting if I start a new series on x86 assembly, as I want to keep the original series so that it uses only C and BASIC.
This series will use Oscar Toledo’s book “Programming Boot Sector Games” as a guideline, and we will use examples from his book as a foundation. Many thanks to Oscar for allowing me to do this.
In this first episode we will start off simple, with the classic “Hello World” program.

I had to stop following your assembly tutorials sometime down the line due to not having time to write the code and try it out myself anymore, but I really appreciate that you continue them and hope to catch up at some point 😀

Since I've had to take down all of my previous VOD's and "highlights" I've been trying to re-stream everything I once had up, with a new setup.

I'm currently going through Urban Assault, and I can't say for when I actually do stream because it depends on whatever my parents feel like doing on their Roku. Most of the time it's impossible to stream at all because of bufferbloat which I've brought up on a thread asking about OpenWRT and routers that can run it.

As usual you can find me here. I will eventually get around to putting up VOD's over at my stupid YouTube channel.

As for why I took everything down previously? I'm tired of having "deep fakes" made of me, so I've basically come to the conclusion it was a mistake to even show my "face" let alone my "voice" on the internet at all, especially during this decade. I will not name names, so don't come asking me who's responsible for this.

I am not sure! It's what my sister said. Another commenter said I have "the voice of a serial killer". YouTube comments are always a treasure trove!

For what it's worth I think you are very good at explaining whatever it is you are doing regardless of what it is, coding, soldering, tinkering etc. I find the videos fairly easy to follow and engaging.

The Gravis Ultrasound ACE

Back in the early 90’s the Canadian company Gravis came out with a range of sound cards called “Ultrasound”, or GUS for short. They were meant to be Adlib and Sound Blaster compatible, as well as having a versatile Wavetable synth, which could be populated with custom samples. It was similar to what the Amiga did, but with way more concurrent samples or channels.
The Sound Blaster compatibility was lacking at best, or non functional in other games. So at one point Gravis left out all that made the GUS compatible and simply put the Ultrasound part on a card called the Audio Card Enhancer (ACE). This card is very sought after nowadays, as you can simply plug it into a retro machine alongside an existing SoundBlaster card. Let’s have a look at it!

Let’s Code x86 Assembly: 0x02 Arithmetics

In our second episode of the x86 assembly programming course we learn about how to do simple arithmetics on the 8086 and compatible processors. We also set up a simple NASM library for outputting digits to the screen.

Finally an actual use for the cutting mat that everyone of us is using for soldering! 😁

Yeah, haha! 😁 Honestly, I´m amazed how durable those things are. Just brilliant and cheap as chips!
