I feel bad that there haven't been any #RC2014 updates recently, despite the fact that there's a lot going on.
A lot of things seems to be depending on everything else, leading to an all-or-nothing workload. I think there is going to be a flurry of new releases towards the end of the month (or early September) though.

In the meantime, if you can make it to #RC2014Assembly at Bletchley Park on September 20th, https://rc2014.co.uk/3855/rc2014-assembly-v1-0/ it would be great if you can sign up - particularly if you have something interesting to display or show off.

Trying to work out what to do with a box of Netbooks. I've got a few I use for consoles for #rc2014 and the like but a definite surplus.

One of the nice things about #RC2014Towers is that I now have quite a large, well lit area for #RC2014 photo shoots.

I am going to have such a lot of fun with this one...

Added an application note for my ZX True Tone module (ZXTT) to show the pinout for using it in other AY-3-8910/12 and YM2149 soundchip applications. While originally designed to replace a chip on Ed Brindley's RC2014 YM/AY soundcard it's ideal for other circuits where you use an AY to play ZX Spectrum music.

The ZXTT provides a clock signal to the soundchip of 1.7734MHz to match the 128K ZX Spectrum ensuring that playback of Speccy tunes is pitch (and envelope!) perfect. (A video on my page shows how much distortion a clock of 1.75MHz gives, which is often used for Speccy related AY circuits.)

Going to be going live in about 45 minutes with one more RC2014-related project: in a somewhat surprising turn of events, a viewer has donated an MG005 Speech Synthesizer kit for me to build. Hopefully I''ll do their contribution justice!

Join me from 2130 BST at https://twitch.tv/baljemmett if that sounds like your sort of thing.

Got wood?

Sorry, I had to pixelate some parts of the images to comply with the UK Online Safety Act. There should still be enough there to tease you though. Can you imagine toggling in a program on this beauty?

Just listed some new #RC2014/#RCBus modules on my Tindie store

First up - #HDMI for RC. Based on the Tang Nano 20K FPGA, emulate #V9958 with extra special graphics modes!

More videos and community links added to my site covering the hardware I've produced for #RC2014 and compatibles.

It's 5 years since I released my first peripherals for the #RC2014 ecosystem, so have £5 off each of my first releases from June/July 2020!

SID Soundchip Interface
- Use the legendary Commodore 64 soundchip in your setup (or modern replacement SwinSID or ARMSID). Also incorporates 50/60/100Hz Interrupt Controller (useful too when using other soundchips for timing playback code.)

Graphic OLED Interface
- Add an easy to use 128x32 pixel graphic display to your setup.

Other RC2014 peripherals...

- *New for June 2025* SAA1099P Soundchip Interface.
- ZX True Tone (ZXTT), add-on module for Ed Brindley's YM/AY soundcard so it's clocked at the exact same frequency of the 128K ZX Spectrum so speccy tunes are pitch perfect.
- ZX-RC Bus Interface, to use RC2014 I/O peripherals with the #zxspectrum
- SAM-RC Bus Interface, as above but on the #SAMCoupe

I’m finding that #RC2014 CP/M can very easily be overwhelmed by the FT245 when using the download program to transfer files.

Using delays in Teraterm, I can either send a single file package fast (several kbytes/second) using a send size delay, or a multi file package slowly (120 bytes/second) using a per character delay.

That is still faster than I ever achieved using the SIO, which was probably 50-60 bytes/second, so I reckon that’s a win

I swear these things are breeding!

Yeah! I've finally got around to building the #rc2014 dual uart board.

I love the new fangled quantum-entanglement methods for serial communication! (Or I may have misplaced where I've stored the IC pack.)

It lives!

The #rc2014 version of my FT245 based USB interface works exactly as intended with SCM, Basic and the 6850 version of CP/M

No more faffing with USB-Serial dongles and #UART settings for me, terminal software simply doesn’t care about baud rates and the like with this board,

This weekend, I have a PCB to build up and test on my #rc2014.

Oddly, 2 sets of boards have gone through production and shipping together, until the last mile delivery!

Now that the news is out, I guess I will be using the #RC2014Assembly hashtag on here.

And if you haven't seen the news, this is a meetup of the #RC2014 community at Bletchley Park on September 20th. This looks like it is going to be an awesome day with people showing off their hardware, demonstrating their software, and talking about what interests them with the RC2014 (including similar platforms like the RCBus or Z50 bus machines, or kits that run RomWBW etc).

Tickets don't go on sale until tomorrow, and I will post a working link (sorry about the oopsie in the newsletter) when they're available.

I hope that as many of you as possible can make it along, especially if you don't normally attend general retro computer meetups.
