I have a crescent idea of making a Sharp-like BASIC pocket computer to play around as a working one is practically unobtainable here in Brazil. The RC2014 looks like a good start.

A bit of fault finding on a RC2014 system for another local builder who couldn't get it to work. It turned out to be a couple of dry joints on the SIO board. It was running BASIC by the time I was finished :-)

First routing done.
Full specs of the new kid on the block: The FX64⚡
8Mhz 65C02 (switchable to 4 or 2 so it stands a better chance of working)
4, yes, 4 audio chips with built in MIDI
2 byte video 💪
RC2014 slightly incompatible expansion bus
C64 slightly incompatible keyboard connector

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

I tried to expand on my #RetroChallenge and build an #RC2014 module that could decode the 8 bits returned from a NES controller using just 74 series logic and a 555 timer.
It didn’t work. I think I have the timing slightly out so some of the logic is triggering too early. I need a dual scope!

Lots of extensible fun for ZX Spectrum here, opening up the world of RC2014 add-ons too.
Some of the #Hardware I make for the #ZXSpectrum came about from suggestions and requests, such as the 2 way expansion connector to connect two peripherals to the edge connector. Also available: ZX-RC2014 Bus Adapter, Int.2 style Flash ROM Cartridge with 2 games, ROM Interface. 🌐 zx.samcoupe.com

A lot of 'replacements' for some of the more well known soundchips of old. There's a whole range of #C64 SID replacements based on ST microcontrollers, ARM, FPGA etc all with varying sound quality. I much prefer the originals - I've been interfacing SID chips to Z80 since 2002! 😜

I've not seen anything to suggest there's a silicon clone of the SAA1099P. The surplus channels seem to consist of genuine old stock and salvaged/desoldered parts. I've used many over the years for SAM Coupe repairs as well as my new SAA1099P Soundchip Interface for RC2014/Compatibles/Z80 systems.

Great to see the ZX-RC2014 Bus Interface in use here to use Robert's RC2014 NES Controller module on the ZX Spectrum!

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.

well, not Trace music, but basically exactly this.

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

I did ponder using edge connectors
But decided to stick close to RC2014 so went for standard pin headers.
