Made a new thing - (available on my store) - a little kit/pcb to connect a pi pico module to the #eZ80 cpu module - to flash and test the module.

#RCBUS #RC2014

Making a new thing for my #RC2014

Blinded by the light.

#Z80 #RCBUS #RETROCOMPUTING

And the next module is

....drum roll please........

The Stegosaur #MSX #YM2413 Music Module for #RC2014 / #RCBus

A perfect match for the GAME module, with its improved sound quality and stereo mix. Check out my blog post:

A made another module. A new 'smaller' module based on the #YM2149 sound chip. And by popular demand, I implemented the 'golden ratio' stereo mix! A full wall of retro sounds coming at ya!

My next #RC2014 / #RCBus module is now listed. This is a #Z80 based module that dynamically boost the CPU speed to 20Mhz when not doing any I/O - so lots of compatibility with stock Z80s modules - but a little bit faster.

No need now to be a slow dinosaur.

It was a bit of a challenge to get all the components on one 5.5cm PCB - as the #V9958 64 pin chip takes up about half the board.

With 64K RAM only on the main PCB; And an optional expansion board to extend the VRAM size to the maximum of 192K.

So I kind of traded length for width! Oh matron indeed!

I have a new #RC2014 #RCBus module. It's part of what i hope to be a new series of module - similar to the Yellow #MSX, but with a more conventional height.

More info on my blog: https://www.dinoboards.com.au/2026/01/04/new-series.html

And available now in kit form from my shop: https://shop.dinoboards.com.au/product/stegosaur-msx-v9958-rgb/

#retrocomputing

Just about to finish my holiday in Mexico. Wanted to share how it started for me. I saw the #woz on my flight to cdmx. Didn't say hello, to shy; he's in bus class; I in economy. Was a great way to start the trip. Might have to move from #z80 to #6502. Did manage to be a bit of a paparazzi and grab this shot. He is probably very lucky I wasn't sitting next to him on the flight. Would pester him a lot and ask if he still wants to move to my home town of Melbourne. #apple #retrocomputing

Kermit may have his issues being green, but I find it super! My friends are all green with envy!

#eZ80, #RCBus #RC2014 #retrocomputing

And to keep everything green. A new simple 6 slot #RCBus compatible backplane.
