I've some more PCB Pin Badges available (SAM Coupe, Commie 64/16/VIC and new Rubber Keyed Speccy) available: www.samcoupe.com/quickshop.htm
They all help add a few extra quid to the development kitty towards the ongoing projects I've got underway for #SAMCoupe, #ZXSpectrum, #RC2014, #Retrocomputing

Soundtracker music for the ZX Spectrum 128K/+2/+3 was amazing! I made an add-on "ZX True Tone (ZXTT)" for Ed Brindley's #RC2014 YM/AY Soundcard to give it the exact same clock frequency as used by the #ZXSpectrum so AY tunes could be played on RC setups and sound perfect.

No, those are 80-pin RCBus ports, for RC2014-type systems, usually built around the Z80 or derivatives.

I love kit computers. #RC2014, SC500, whatever. They're all great.
But they all share one great big annoyance: Putting them in a case. I hate how much work it is to find or fabricate a suitable enclosure. And I'm comfortable with tools.

Great to see my new SAA1099P Soundchip Interface (for #RC2014 and compatibles) in use playing some fab music from the #SAMCoupe on the #ZXSpectrum (via a ZX-RC Bus Adapter). Nice work!

Here’s another nice SAA tune; this time playing on my 48K Spectrum (with Microdrive and Interface 1) using @samcoupe.com’s SAA1099P interface and bus adapter. I’m using a new faster playback routine by Anton Javorček here, it sounds great! 🔊🔊

Thanks to a suggestion from @cobracommander.bsky.social earlier in the year, the SAA1099P soundchip is available as my newest interface for #RC2014 and compatibles! Use the same fab soundchip as the #SAMCoupe on other Z80 systems!

This idea for a RISC-V machine similar to RC2014 seemed like a good one so I've been thinking about it for the last few days.
I've put together a rough plan for how it might be done - I'm interested in what people think!

Also useful if you get yourself an RC2014 kit.

If you're going to switch from 5v to 3.3v either you need to make the bus physically incompatible or at least, make the rc2014 5v pins n/c and move the 3.3v rails to currently unused pins. Otherwise I foresee lots of fried chips!

Not that different to playing with my RC2014 Orton 3C with the extra ports I've added :-)

I've been working a bit more on my #RetroChallenge, getting an #RC2014 to talk to a NES controller.
In my latest post, I explain how I've used Z80 assembly language to work out which buttons are being pressed and to print this back over the serial terminal.

More code, more switches, more LEDs. The monitor code is now in the EPROM. It copies itself down to 0000h so it runs directly from a reset. I've also found a rather nifty Linux hex-editor called hexcurse. #RC2014
