16C550 Serial Module

With the Zilog SIO/2 serial chip reaching End Of Life last year a replacement is needed before stock of those chips run out.  The 16C550 UART is an excellent chip and already has full support in RomWBW.
The 16C550 Single UART Module was released at the end of 2024 and can work on any of the 8 address ports that RomWBW supports, and can even work alongside 68B50 or SIO/2 modules to add more serial I/O to your RomWBW machine.
The 16C2550 Dual UART Module launched earlier in January does everything its little brother does, but with the benefit of having two serial ports, both of which can have their address ports set separately.

Sharp MZ-80K

Is there a Sharp MZ-80K hiding inside your RC2014? Well, if you have an RP2040 VGA Terminal there could be! Tim Holyoake has built an emulator for this classic Z80 machine that runs on an RP2040. Just download the .uf2 file from GitHub and drop it on to the card via USB.
The only question we have is when will the MZ-80A be ready? :-)

TTL Logic Probe

If you need to debug a problematic RC2014 or just want to take a deeper look at the signals, the TTL Logic Probe is just what you need!
Remember when YouTuber Stuart Patterson built his RC2014 Classic II a few months ago? Well now he wants to use it with a VT100 terminal. And for that he builds a Baud Rate Converter

DTFM Codes on an RC2014

Not only did Rob Price build a DTFM (telephone keypad tone) decoder module, but he also used his AY-3-8910 module to make DTFM tones. Along with the keypad, I suspect smart phones can finally become smart with a Z80 powering them!

How do you make a Why Em-Ulator go cheep?

By using the discount code CHEEPBEEP at Z80 kits before the end of February!
 
That's right. There is 10% off of the Why Em-Ulator and SID-Ulator at z80kits. Simply enter CHEEPBEEP at checkout to save money on these emulated YM2149 / AY-3-8910 and SID modules.
