    Your newest piece of retro-tech

    Yes. However, the terminal program didn’t seem to have a way to disable sending an init string, which makes it awkward to use as a dumb terminal. I ordered the keycaps from WASD Keyboards, using a custom layout file. I can’t give you that one, as it was shared privately, but I’m building a new...

    Your newest piece of retro-tech

    New keycaps for my USB keyboard. I spent most of this evening getting VICE to work properly with all the keys, then getting VICE to talk to my Altair clone....

    Why Johnny Can't Code...

    Yeah, it'll have to sit somewhere in the $50-100 region to make that work. That's not really going to happen with an FPGA, but it might possible with a large enough quantity of ASICs. The C64 DTV sold for like $50, after all.

    Choosing a computer

    It's all going to depend on what you're doing. Any program that runs too fast on the Pentium is likely to run too fast on the 1850, as well... this is because early PC games used simple loops to slow down the program, rather than relying on hardware timers. Games written to work on 286 and 386...

    Why Johnny Can't Code...

    This is one of the reasons David is creating the Commander X16... to have a truly new computer that can be used in the classroom to teach kids programming. Personally, I think a DOS machine with QuickBASIC is the ideal programming environment. QB is simple enough that anyone can understand it...

    Choosing a computer

    The 420 is apparently a 100MHz Pentium, where the T1850 is a 386. All other things being equal, I'd probably choose the Pentium (The 420 CDT), since the larger, faster system will give you more options for DOS games and software.

    File I/O from the SD card issues

    No, I've basically given up on the emulator until the codebase stabilizes. But you can report the issue on their GitHub. It's probably a 6502 code issue, so you will probably want to report it on the ROM git. https://github.com/commanderx16/x16-rom https://github.com/commanderx16/x16-emulator

    keyboard concerns

    You are probably right, on both counts. It remains to be seen how effective the PS/2 input will be without a dedicated controller. It wouldn't be hard to implement a keyboard controller on a dedicated microcontroller, and there are some super-cheap MCPs that could do the job. We'll see what...

    The Chloe 280SE

    Thanks. I've been working on a few demo games - character based games that can run in 100% BASIC. But I also want to get back to assembly on a user-friendly Z80 computer, so this seems like it has promise.

    the-8-bit-guy and iconic ZX-Spectrum (not zx80/81)

    I think I maybe took away something very different from your statement than you intended, hence the confusion. Yes - both computers were meant to be affordable. The Apple II sold for $1298 in 1977 ($2638 with 48K of RAM), but I always felt like Woz was more about the science and the creation...

    The Chloe 280SE

    Thanks for the post. Could you maybe give us a bird's eye view of what state the project is in, in terms of hardware, the operating software, and the BASIC interpreter?

    x16emu locks up when loading Basic demo programs

    You actually don't need any external tools to tokenize a BASIC program stored as text. If you start the emulator with the -bas switch, the emulator will "type in" the specified file for you.

    the-8-bit-guy and iconic ZX-Spectrum (not zx80/81)

    Again... this is not true. The Microsoft BASIC available when the Spectrum was designed was much more advanced. Advanced BASIC was basically Microsoft BASIC 6, which included graphics commands and a bunch of logic and string management operations. Sinclair BASIC is markedly inferior to the...

    the-8-bit-guy and iconic ZX-Spectrum (not zx80/81)

    Sure, if you cherry-pick examples, you can say any two computers are almost identical or nothing alike. The PC also had a "beeper" speaker. The PC, Apple II, Altair 8080 (and its clones), and Spectrum were all made using off the shelf components and offer a simple, parallel expansion bus. The...

    Looking for the Content of the "Computer-Lernkurs" C16 Cassette

    Nice. =) you can try the TAP files in the C16/Plus 4 emulator in VICE before writing them out to tape. Let us know how that goes.
