The body made up of one sprite. The sprite has some lines to skip, and it looks like the line-skipping breaks something.

Re: Porting the ChibiAkumas to the Elektronika MS-0511

as for connecting an AY chip to the UKNC, that's really incredible In terms of logic, it's not as difficult as it may seem. It rather resembles programming. The tricky part is in physics. You have to consider what happens on the level of physics to design a circuit board. This is why it most intimi...

Porting the ChibiAkumas to the Elektronika MS-0511

At the end of 2018, I started the project. But I worked only occasionally. Recent events allowed me to spend a lot more time on the game))) https://i.ibb.co/CB3gx0W/DSC-0616.jpg Still, there is much more work to do. So I decided to create a topic here, to track progress and ask questions. There is a...

Re: PDP-11

I had those figures in my notes for a while, and yeah, they are pretty concise. I believe that I took them from one of the DEC manuals, but I don't remember from which one. I'll be happy to help if you need some information to continue the tutorials. Recently I added a keyboard scan-codes table, wit...

Re: PDP-11

About the octal numbers. Sure, they look weird because "modern" bytes consists of 8-bits, and general microprocessors have 16, 32, or 64-bit words. But for example, the very notable predecessor of the PDP-11, PDP-8, has 12-bits words. As for the PDP-11, octal numbers pretty practical for a hacker. I...

Re: PDP-11

I just enjoyed watching the very first tutorial in the PDP-11 series. Excellent video :ThumbsUp It is especially touching that people got interested in the series :Wow: and I'm looking forward to the new tutorials as well. I'm anxious to add that in the Soviet Union, the PDP-11 compatible systems an...

Re: PDP-11

I'm sorry Keth. I found that it is difficult and time-consuming for me to translate the documentation (I tend to overthink and procrastinate too much in the process))) It would be much easier if I leave detailed comments it the code I currently write. For example , I described "line parameters table...

Re: PDP-11

It took me a while to contrive some examples. In the end, I modified the memory copy test I wrote a year ago. In the example, a code block is sent to PPU to create a new "lines parameters table" to modify colors and line scale. BTW, new version of UKNCBTL was released. Now you can run the emulator w...

Re: PDP-11

Here is link to MACRO-11 Reference manual.
VT52 manual
And here is manual which describes how to work with external devices - terminal emulator, PPU, etc.

It's very late in Moscow :) I'll prepare code examples tomorrow.
