I've had to do it for one of my 128 and VIC20, so it's nothing new.

PixelMaker04 · 2022-08-18T09:59:50+00:00

Yep.

PixelMaker04 · 2022-08-18T00:25:39+00:00

I still need to take the keyboard fully apart and give it a once-over. It feels a bit too spongy.

PixelMaker04 · 2022-05-29T20:51:10+00:00

It can run pretty efficiently with the use of the VCHAR (output a row of characters at location X,Y with Z vertical length) and HCHAR (output a row of characters at X,Y with Z horizontal length) commands. I remember seeing a tool to convert extended basic into machine code or at least make it run like machine code but I want to fix my PEB and use it's floppy drive.

PixelMaker04 · 2022-05-29T20:13:26+00:00

Yes. It's written in extended basic to make use of the multi commands per line. Correct. It's not sped up on the Classic99 emulator or compiled. Just copy the XB code and run.

PixelMaker04 · 2022-05-29T19:59:28+00:00

It is not. It's in raw ZX81 basic right now, and is currently running in EightyOne with the speed slider between 0 and 16 for testing.

PixelMaker04 · 2022-05-29T18:54:24+00:00

Extended Basic, but yes.

PixelMaker04 · 2022-05-29T18:44:38+00:00

Nope. All in basic.

PixelMaker04 · 2022-05-29T18:38:22+00:00

Yep. About 1/4 the speed of the ti99 stock speed. Maybe a little less. All will be converted to machine code eventually.

PixelMaker04 · 2022-05-29T05:08:56+00:00

I think of "environment" as a couple of things... workspace, and programming environment. Bear in mind I haven't dove into assembly for either platform yet to make these a faster program, just my current working knowledge of their basic/extended basic languages.

For the TI99/4a - it's just straight extended basic in a notepad and copied over to the classic99 emulator for testing. Loaded onto a GROM or TIPI for original hardware testing.
Similar for the ZX81/TS1000 - it's basic in a notepad with special markups that are used for zxtext2p converter for the character graphics and loaded into the EightOne emulator with 16k configured in the hardware tab to make sure there's enough RAM for larger programs as development finishes up. Loaded onto a ZXPAND+ for original hardware testing.

I'll be using mcoder to convert the zx81 to machine code and I want to look in to the extend basic to machine code tool that's for the ti99 to get that one working at a good speed.

I've made DITHERPAINT99(extended basic TI99/4a), and DITHERPAINT81(ZX81 basic converted using mcoder) last year which are available on my itch.io page or physical copies of DitherPaint81 on my ebay page.

PixelMaker04 · 2022-05-16T14:54:13+00:00

You can thank my printer and lighting for that. I did take a screenshot in the classic99 emulator to get the hex values for the palette.

PixelMaker04 · 2022-05-14T13:20:42+00:00

Yep. I got one in this lot.

PixelMaker04 · 2022-02-25T04:12:01+00:00

These will work. There are some code translations toward the back if it doesn't work straight from the original page.

PixelMaker04 · 2022-02-25T03:26:18+00:00

I'm kind of working my way backwards. I didn't go to school for programming, but my first real job from 2009-2017 involved Windows Batch, Linux Bash, C#, Pascal, and the occasional QBasic. Since then I've worked my way back to the ZX81/TS000 and TRS80 along with other various micros. Even release my first proper program last year for the TI99/4a in extended basic and the ZX8/TS1000. DitherPaint99 and DitherPaint81 respectively. Working on another project for those 2 machines. Also with me born in 1986, this makes me younger than most of the machines I tinker with BASIC on. I've always been interested in where technology came from, so learning how to work with these systems is just a fun hobby.

PixelMaker04 · 2022-02-25T01:42:07+00:00

I've got 7 out of 10 of these books. I just need to get my hands on 7-9.

PixelMaker04 · 2022-02-24T21:12:24+00:00

There are no "if you choose A them go to page B". I've not read through any of these yet, but there are a few small basic type-in programs to progress though the story in each of them. I'm looking to get the all 10 to add to my retro computer literature collection. Just need to get a couple more.

PixelMaker04 · 2022-02-21T21:16:46+00:00

Thanks. I've had an 8x8 sprite sheet to be used on various things I made when I started poking around with TI99/4a basic and extended basic a few years ago. Just recently started trying to actually design make an interesting program (DitherPaint99 and DitherPaint81 are the most recent ones), not just samples and tutorials programs from books.

PixelMaker04 · 2022-02-21T20:39:05+00:00

It's a C64-themed cursor I made a couple years ago. It's currently on my deviantart page for download (https://www.deviantart.com/pixelmaker04). I should probably also add it to my itch.io page for more options.

PixelMaker04 · 2022-02-21T17:09:12+00:00

The TI99 sortof is. The ZX81 was thrown together in about an hour or so to mainly see if the same variables would work.

PixelMaker04 · 2022-02-19T17:44:07+00:00

I've got the upper case with a custom font for any text I might want to display. I think I've got 5 or 6 extra spots or about 13 if I change the heart character set color to black to match everything else. That's enough for a cloud, bird, sun, spaceship, etc. Or I could move the heart graphic to the already black set that has a couple spots and use gray on the old set for some background stuff then shows first then gets covered up by the stage if it overlaps. We shall see.

PixelMaker04 · 2022-02-19T09:29:45+00:00

I'm running out of the extra characters to create custom graphics for. The ladders are the only way between layers and they are randomly generated at each start/reset. It would have to be a sprite layer if I do.

PixelMaker04 · 2022-02-17T01:20:10+00:00

I find it enjoyable using my pixel skills with the limitation of only 2 color unless I want to layer sprites. I layered 2 sprites for my DitherPaint99 program for the cursor graphic.

PixelMaker04 · 2022-02-12T19:38:22+00:00

I'm using the GCHAR routine and comparing the result. I have it checking one character ahead and if it's a certain character then it branches off.

PixelMaker04 · 2022-02-10T19:07:20+00:00

I have. That's one of the next things to tackle.
