I'm amazed this SCSI hard drive still works. However, the adapter card only boots with a 486 motherboard or lesser.

New video: Let's Code MS DOS 0x2F: Mandelbrot Fractal

Everybody knows the Mandelbrot set. It is one of the most famous fractals. And it is easy to code! At least if you don't care about speed... So let's try to code it for ancient MS DOS PCs with VGA cards! And there will be color cycling!

The same MSX-FAN magazine contains a guide about Metal Gear 2. It recommends saving money because the game is going to be released Jul/20/1990 (the magazine date is Aug/1990)

@montyontherun Thanks! I'll give a look so it can be corrected by the maintainer.

Now you can develop CVBasic programs completely in the web. Edit, compile, test, emulate, and download compiled ROMs! Thanks to haroldoop for this amazing development. haroldo-ok.github.io/CVBasic-e

The screenshot shows the text editor, compiler options, compilation button, download button, the generated assembler, and the emulator running a game.

I just noticed Toy Story was released 30 years ago! Wow! That's a lot of time! BTW, did you know Pixar had some transputer-based rendering boards? fxguide.com/fxfeatured/pixars-

Do you remember my non-working C64 keyboard? It improved cleaning the PCB board with isopropilic alcohol, then I cleaned every single key contact (the black piece with two gray-like pins) It works again! Although in very bad shape (broken Caps Lock) 😀✌️

@tubetime I don't see any memory, I guess it is a frame grabber by column. You need a still frame and get the full column. In five seconds you get the 320x240 image. I remember a project like this in Radio Electronics ebay.com/itm/393452182851

A good friend brought me these from Japan. I love the BASIC listings on the magazines. Also got Dragon Quest for MSX when Enix wasn't part of Square 😄, Ashguine, and Konami Soccer.

How to train your dragon (2025 live-action). A faithful recreation of the original animated movie about a teen who discovers a unique dragon, keeping all the emotiveness, and very rounded and well done. Disney could learn a lesson from Dreamworks. Recommended.

I don't have anymore a Laserdisc player, but I considered 1000 yens for this Gall Force trilogy was a real offer!

Whenever you think your TMS9928 graphics are good, you must ask yourself if you reached Konami's quality 😉

I was testing KiCad 9, one hour to draw the schematic, five hours for the PCB, fifteen minutes with PCBway, waiting one week, and five hours to build the board (time wasted because my oscilloscope failed). I made two mistakes, but it works!
