Wintermute_BBSFixed my "Dual Clock Module" this morning. Not one for the eye, but at least It's working again.
QuazarKeep your #ZXSpectrum AY tunes accurately pitch perfect! Save £5 this weekend on my ZXTT (ZX True Tone) module. Originally designed for Ed Brindley's AY/YM Soundcard for #RC2014 but easy enough to incorporate into your own AY-3-8910/12 & YM2149 circuits, or hack into other AY Interfaces to feed them the correct 128K clock signal. (I've seen a lot of ZX Spectrum AY add-ons use 1.75MHz which is NOT the correct frequency!)

Springtime is knocking at the door, so we did some very early spring-cleaning 🧹
RC-BOX BBS, the world's first (and currently only) Bulletin Board System to run on real RC2014 hardware (Z80 based Homebrew Kit) utilizing oldie-but-goldie CP/M 2.2 has seen a minor update:
- new "read latest bulletin" prompt after login, skip the bulletin if you don't want to read it / already read it
- fixed total line count at message output
- raised max lines per message from 48 to 64 (at 64 columns per message line)
- added some essential software to the file base (for those brave enough to try x/ymodem downloads).
Visit us using your favourite terminal program. Heck, we have no ANSI so even a teletype will do!

TristanAre you able to change the horizontal frequency on a 'rp2040 vga terminal' for the #rc2014 because it would be so cool to use one of my weird CGA monitors with it.
Martin EA7KRCMe apetece montar otro kit de electrónica, estoy mirando el RC2014, ¡pero no sé qué haría con él una vez montado!
I fancy making another electronics kit, looking at the RC2014 but I don't know what I would do with it once built !
Retrofan 64My #rc2014 has apparently made it through customs and is in the sorting facility.
I'm seriously pumped to up my soldering game on this bad boy. It'll also be a treat to have a system that makes my C64 look like a leviathan. :P
This is what I see on my living-room TV when someone logs on and downloads a file from RC-BOX BBS

To answer a question I was asked, of course I'll also do the 15% discount directly to save you having to go through Tindie. I don't have the offers live on my https://2014.samcoupe.com website so please just private message or email me and I can send a PayPal invoice with the discount applied.
Save 15% off my #RC2014 (& compatibles!) peripherals at my Tindie store this weekend! (8th/9th March).

SID Soundchip Interface
SAA1099P Soundchip Interface
Graphic OLED Module
ZX True Tone Module
ZX-RC Bus Interface
Where possible I'm happy to customise hardware I make. This example is a version of my SAA1099P Soundchip Interface for RC2014 & compatibles, modified for use in a homebrew 6502 computer which simulates a Z80 bus for driving a couple of RC style expansion slots.
Although for this setup only address bits A0 - A7 are available, as the 6502 circuitry is using a 256 byte window in its memory map for the simulated I/O address area. As the original SAA Interface uses A0 - A8 to match the decoding per the SAM Coupe I had to change the decoding circuitry to remove the dependence on A8, which I switched to A0 and used A1-A7 for the base I/O address that can be set by jumpers.
For the full range of peripherals I make for use with #RC2014 & compatibles please see my dedicated site at: https://2014.samcoupe.com
