#rc2014

I love how sharp the #RC2014 logo has come out. Running a kiss-cut around it after the engrave really helps to darken it up. I think I should have done that with the rest of the lines and text on here too. Shellac has made the cherry veneer look great, but I still want to try wax and oil finishes.

Thanks everybody that responded, and sorry for not responding to every reply.

I think the results have confirmed my original thoughts. I will certainly be making a feature of the fact that this computer will run on just 3 chips, so hopefully that will keep the 26% that felt cheated happy.

As for the 36% Intrigued and 31% Curious, well, you should be. I won't go in to the details just yet, but I'm sure you won't be disappointed.

There's some updates needed to the prototype, but if all is well, some time next month I will introduce the latest kit to the #RC2014 stable.

Replied to RC2014

@rc2014 @electron_greg back in school we had a special, modular custom-bus based #intel8085 system to teach us about computers and programming.

It also had a switch panel and I fondly remember looking up opcodes in a photocopied table so that I knew which value to "toggle" next on the switches before writing it to a memory address. Hands on computing, the real way.

It was called #MFA (microcomputer für ausbildung - microcomputer for training) and it also ran CP/M and featured a #Siemens #SPS module (god, I hate SPS).

It was this system I learned #intel8085 #assembler on.

P.S.: I guess this baby and the fond memory I have of it made me fall in love with #rc2014 decades later ...

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.

All the info / order / see what else I've released: 2014.samcoupe.com

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

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,

A surprise extra instalment of RC2014 adventures tonight, as MajenkoTech's viewers have voted for me to carry on and build the mystery add-on module I bought from @rc2014 in person at last year's #emfcamp.

Tune in from 2130 BST at twitch.tv/baljemmett to find out which very important peripheral I'll be adding to the machine tonight!

(I was going to give everybody a short break and do something else this week, but the people have spoken and who am I to disagree?)

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.

Soak testing new SAA1099P cards for RC2014 via a SAM-RC Bus Interface on my SAM Coupe computer.

With four cards, plus the SAA built into the SAM, that gives a total of 30 SAA sound channels... Hmmm...! 🤪

2014.samcoupe.com
for all the hardware I've designed for use with the RC2014 ecosystem and compatibles (inc. ZX Spectrum via a ZX-RC Bus Interface!)
- SID Soundchip Interface
- Graphic OLED
- SAA1099P Soundchip Interface
- ZX True Tone (for YM/AY soundcard)
- Bus Interfaces to use RC2014 peripherals with several home computers.

🚨 Website Update!
I've just updated my dedicated website for the hardware I produce for the RC2014.

Now listed are the ZX-RC Bus Interfaces I released in 2022 for connecting RC peripherals to the ZX Spectrum. (Allows 2 RC peripherals to connect, with optional ZX Through Port).

Likewise, the SAM-RC Bus Interfaces (first released in 2019) to connect RC peripherals to the SAM Coupe are also added, available in 2 or 4 port versions.

For all the info, videos showing a selection of RC peripherals working with the two home computers, and to order please see the page at:

Tonight is going to be part 8 of my #RC2014 Pro Pride kit build, assembling the final module: the digital I/O board, which has eight LEDs in a variety of colours that I'm definitely going to need chat's help to identify. So hopefully at least some of you will join me at twitch.tv/baljemmett from 2130 BST for that!

Depending on how long it takes to build, we might also give the ESP8266 Wifi module another whirl, now that I've corrected my silly resistor mistake from last time...
