ZX81 ZXpand+

Just a quick video to show the long awaited awesomeness of the ZXpand+ for the Sinclair ZX81. This adds SD card for loading and saving programs instantly, a joystick port, and sound output.
Long live the Sinclair ZX81 :)

You make my high school dreams true...i envy you😪

[@RichSzerman]

I just got one of these. Looks promising. Planning on coding some basic programs using it. Is there a means of being able to query the sd folders back to an array in basic or memory location? I would like to code some basic to call files on SD etc thanks

[@byteforever7829]

I've not tried that but must be possible, normally any command you can type at the prompt can be done in a program

[@Alex_Valentine]

I wish they'd make these again. I'd love to have one and not use my tapedeck to save programs.

I kinda want one of these.
But at the same time, I want my zx81 as stock and unexpanded as possible in order for it to be a 1k only "powerhouse" 😅

[@cozzy900]

1k powerhouse 😂

[@whatamalike]

@@cozzy900 I'm not wrong lmao

I still keep one totally standard. In the 80s they were doing upgrades (16k rampack etc) memotech did various keyboards and expansions for edge connector. I think they had 5 add on including an assembler module and 32k ram. They are unobtainable though😓 although I can load from the Mic I can't get the save to work no matter what I do. So other than Wespi esp32 (which I also couldn't get working) this zxpand and sd card is the best thing. For some strange reason that I can't understand myself, I want to write assembly code on the real zx81 using the bugbyte ZXAS

​ @byteforever7829 the vic20 is my main tinkering machine, love the challenge of doing things in such a small machine, no fancy commands or extra chips doing the work for you.

[@RichSzerman]

where can you get the SD card to work with this please? Any idea about the latest firmware?

[@byteforever7829]

There's a post here that tells you about the file browser www.sinclairzxworld.com/viewtopic.php?t=671 but you don't need the file browser just drop files on a fat32 formated sd card (probably is a size limit 16Gb bit not sure), you can then use the key shortcuts i think i nentioned or the standard load save etc

[@ncurtis1970]

Ive always wanted an 81 just to see what I could make it do.
ZXpand+ would be next on the wishlist.

[@ncurtis1970]

thank you for making this vid. i never knew this existed.
