Look what I found, dusty and forgotten. Let's see if it still works.

    M4 FORTH is a compiler for the and the ZX Spectrum. It generates Z80 assembler code from macros.
    https://github.com/DW0RKiN/M4_FORTH

    The developer claims that M4 FORTH produces a shorter code and 2-4 times faster code than zd88k, "probably the best compiler for the Z80"

    You don't have to believe him however, the developer is keeping himself honest with this extensive set of benchmarking tests:

    1/ The computer partly dismantled here was likely the highest-performance 8-bit machine of the early 80s. Very few were ever made. It's an EXQUISITE design that, however, disregarded manufacturability and serviceability. A treasure regrettably lost to time. Guess its name!

    @TheByteAttic It could be an Oberon machine.

    Amazing re-creation (work in progress) of Bruce Lee on the virtual platform, by pahammond.

    Paul has also re-created a number of other classics on the Pico8, such as Moon Patrol, Bubble Bobble, Pengo, Phoenix, and more!

    Watching TinyTim78 play Digital Duck's brand new PC game Manic Miner Redux on Twitch right now.

    So impressed with this game. It incorporates levels from all the various versions of Manic Miner but does them in a Spectrum style.

    I take offence at Sinclair's ZX Microdrives being called "odd" 🤣 They were a magisterial class on how not to design mass storage devices.

    Gosh, corporate Democrats will just cheer for anything that chants USA! USA!. Never mind that dropping the atomic bomb on Hiroshima and Nagasaki was one massive war crime, mass murder of ~200,000 innocent people when most were waking from their sleep, and doomed thousands more to lives of pain and horrifying disease.

    What a bunch of stupid and awful American idiots just like the other ones.

    Further ideas on the topic of , and how we define the je ne sais quoi of it.
    https://mastodon.social/@haitchfive/110783239725491672

    I just thought I'd give an example of a computer that was assigned to me at my first computing "job". It was an EPSON Equity+ PC-XT compatible computer. It was nice and fast at the time, with a clock speed about twice of the original IBM PC and a 20 Mb hard disk drive. At first I was allowed to write simple inventory applications in GW BASIC when I wasn't doing something useful.

    haitchfive,
    @haitchfive@mastodon.social avatar

    Then they saw that I had mastered that language very quickly because I already knew some basic from my Atari 800XL and ZX Spectrum experience. So after a month or two of doing that they gave me simple database programming tasks using dBASE III+ for MS-DOS. Up to this point it was all just programming to me, there was no notion in my mind about the commercial value of the real estate software I was helping to develop. After getting acquainted with dBASE III+, dBASE IV, FoxBase were released.

    haitchfive,
    @haitchfive@mastodon.social avatar

    I kept learning all those dialects of the then-called "XBase" family of languages, and I became acquainted with Clipper, a compiler and Xbase dialect created in the mid 1980s by the long-deceased company Nantucket Software. Clipper was able to do a lot of the things that dBase and Foxplus could do, but faster, and it felt for the first time like something closer to a real programming language, not a scripting toy.

    haitchfive,
    @haitchfive@mastodon.social avatar

    All of which I promptly did profit from extensively, writing low-level interfaces to connect database software with the outside world. And these new fancy devices whimsicaly called "mice". This is all pre-Macintosh, pre-Amiga, pre-Windows world.

    haitchfive,
    @haitchfive@mastodon.social avatar

    It didn't feel to fast to me at the time because I had no parameters of comparison, but I can now see on hindsight that I had done quite an astonishing lot in just a couple of years.

    And then I very rapidly became bored with real estate and accounting software. And I found myself more and more often using the exact same tools that were my bread and butter (for a young kid who still was in high school at the same time, it wasn't really my bread and butter, it was more like marmelade on top of)

    haitchfive,
    @haitchfive@mastodon.social avatar

    And what else could I use that extensive tooling for?

    Games. Obviously. Text adventure games.

    Which didn't have to deal with the memory constraints of the ZX Spectrum or the Atari 800. I could use databases of tens of megabytes, which was unimaginable for regular Spectrum users in 1989.
    And they could be written using Clipper, which was efficient enough and good enough of a language not to leave dangling pointers without much hassle, and serious enough that I could do anything with it.

    haitchfive,
    @haitchfive@mastodon.social avatar

    Is all that retro computing? Sure as hell it is... the labour of love side of it.

    The text adventure engine that could feature unlimited rooms, and rudiments of a scripting language that looked a bit like LISP.

    No one at that company ever knew it existed at all. All they cared for was that the accounting software kept clients happy. And happy they were. That bought me freedom to keep doing what I actually loved to do, which was to engage with other more intellectually interesting projects.

    The Zeal 8-bit Computer is... well, you already know...

    Based on the CPU, it features 512k of RAM, and it's built from currently available components.
    http://zeal8bit.com/getting-started/

    OS and FS source:
    https://github.com/Zeal8bit

    Runs CP/M too:

    Work on a video board is ongoing, based on the Lattice ECP5. It looks like a good idea as other projects could reuse the video module.

    Graphics on the Zeal 8-Bit computer

    • separate video board
    • FPGA-based (Lattice ECP5)
    • 80 x 40 text mode
    • VGA 256-colour palette
    • Tiled mode
    • Tilemaps are 8-bit indexed
    • Tiles are 16x16 8bpp squares
    • 640x480 VGA resolution, but there's no bitmapped graphics mode.
    • Work is ongoing on sprites and other graphic modes
      (Sprites can be positioned anywhere, not limited by a tile grid)

    Disk image archive and info resource for the Sanyo MBC-550 PC "compatible" from 1982. It's an interesting clone that features better-than-CGA 640x200 resolution 8-color graphics, ending up with a few unique titles, as such.

    That's indeed a strange graphic mode, it's not supported by any of the standard CGA, MCGA, EGA, or VGA.

    @hbons That looks nice indeed! Maybe keep it as an option switchable with a sequence of control keys.
