Achievement unlocked? 🤣

Finished building the SD2IEC kit. On my first try I ruined the USB port that's used for power but the dude selling these kits was very nice and sent me another USB plug.

Happy to report that it works, even with the old Epyx FastLoad cartridge. Alas my WarpSpeed cartridge does NOT work, weird.

Now to figure out if there's newer firmware, this shipped with 1.0.0? 🤔

Anche sta volta #chatgpt ci ha azzeccato , creato un piccolo programma , che legge il file in ram , e scrive su floppy o su #SD2IEC un file di testo in formato #seq . Essendo un file di testo lo si può aprire ovunque . Successivamente, chatgpt ha creato un programma che apre un file seq mantenendo il formato testo . Il passo successivo ? Selezionare il file seq aprirlo come testo e convertirlo come file prg eseguibile . Direttamente da un vero #c64@computer #retrocampus

I am starting to take a serious look at the #c64 and #vic20 machines in my collection. I want to get these going again sometime soon. I know about recapping and I have a friend who can do that part for me in trade for some hardware. But where I am currently "blank" is stuff like "how do I even get a picture on an LCD" and "what are good power supplies" and "how do I interact with modern storage" and so on.

I've seen a variety of #SD2IEC solutions for both platforms and there seem to be things like the Kung Fu Cartridge that can emulate fast loader cartridges that work with both regular floppy drives and SD2IEC devices. But it's often unclear which versions of these to buy. For example, are the versions on #tfw8b better than those available elsewhere? How do I even find out?

Printed a case for my C64 SD2IEC+Epyx fastload

Case is kinda janky but I cleaned it up some and used a little super glue to get it fixed at edges. Works great! Really glad I have nice label sticker printer to make my own button labels!

I did have to remove and resolder the SD card board as it was on crooked and too low. Needed hakko + heat gun to get it free. Once back in fit in case properly.

My arrived today, I set it up and tested it straight away. My early version of the actually still has the original in it and it actually still works just like my Joyboard controller. Unfortunately you have to twist it downwards but that's ok. Unfortunately my seriell cable still needs a bit of work but then it's actually done.

I believe that #pi1541 is the worst way to spend money on #c64. It's just fine for recreating real floppies using it with a real 1541. Compatibility much lower than #sd2iec for my experience

@vkc This may not answer your specific question, but Greg Naçu from #C64OS has published a combined #SD2IEC manual online: c64os.com/post/sd2iecdocumenta #c64

Pues ya me he creado unas cuantas imágenes de diskette vacías para el #SD2IEC que funcionan, así que esta noche me pongo a descubrir el :commodore: 64 en profundidad.

La imagen muestra un emulador de unidades de disco SD2IEC. Es una caja de plástico conectada al commodore 64, ocupando el puerto serie y el puerto del casette, con dos pilotos LED y dos botones negros a la derecha de una ranura para tarjetas SD.En la imagen está el manual oficial del Commodore 64 abierto por el capítulo 3, “BEGINNING BASIC”. Bajo este manual están los 4 libros de la serie “Step By Step Programming Commodore 64” de Phil Cornes.

PAL-1 ... now with added IEC serial interface! #pal1 #mos6502 #commodore #sd2iec @futurewas8bit

An SD2IEC drive connected to a PAL-1 computer with an IEC serial interface gadget. The SD2IEC drive is powered from the IEC interface using an adapter that has a VIC20 cassette port edge connector.Closeup of the IEC serial i/f gadget for the PAL-1 computer.

Now I have finalized the TCBM2SD firmware. I managed to squeeze in read-only support for disk images (D64/D71/D81).

This pretty much completes what I wanted to achieve. The next step could be a cycle-exact 1551 emulator (Pi1551 base on Pi1541, but that's a completely different project).

The author of Directory Browser kindly shared the source code with me, so there is now a version that supports the native fastload protocol (23x, ~9KB/s) for files and directory listings. The browser can be easily loaded using the SHIFT+RUN/STOP combination.

Everything about the project is open-source and published at github.com/ytmytm/plus4-tcbm2s

But if you own a Commodore C16/C116/Plus4 and you'd like to buy a ready-made TCBM2SD from me, please send me a message. Let me know how many you'd like and include your country of residence. I'll be ordering PCBs soon, so I’d like to estimate how many will be needed. Once I have that information, I’ll get back to you with a price offer.
