Thanks @LaurentFr And yes there are.
github.com/peterzieba/5Vpld is an excellent consolidation of all the different ways to code em. I used wincupl as the yosys/verilog option does not support tristate pins. I packaged a full toolchain into a single docker image to make it easier for me.

I have 2 wip repos:
github.com/dinoboards/vga-for-
and github.com/dinoboards/cpld-too

Doing the best I can to distract myself from the madness of the world. Just powered on my latest design for the on . A 5V graphics module. 640x480 @ 256 glorious colours. As the guy in the basement would say "it freakin works!"

my latest design - a VGA module for eZ80 on the RCBus platform - installed into backplane for testingThe very first power on with monitor connected.  Rending all the random bytes from its onboard SRAM memoryWith a simple memory write by the #eZ80 CPU - a test pattern is produced.  Confirming CPU and Video access to RAM

I have listed my eZ80 for RC kit on @lectronz . EU customers may find its support for VAT collection more convenient. The store is open to all.

Would you like my other kits(Yellow MSX) listed here also?

working on the challenge of implementing for the with full graphic support (with video). I had forgot just how capable the graphics system was. Long way to go - but got the little rocket demo from the original manual working...

Am I dreaming? Can I port to my on . Might be hard on a stock VDP, but perhaps my fpga version of it.

@SM0RVV Great to hear its arrived. Hope you have fun with the build - and yes those pins are small - so don't sneeze! Good tweezer, clean desk, some patience and you will be fine. Good luck😀

ez80 continues to learn old tricks.

@hp still experimenting a bit. Take my time with it. Use a bit of flux and soldering iron. Start with one pin. Then another on the opposite side. Then gently let the solder and flux flow with the iron. Don't have a microscope - have a magnifying light that helps a bit.

@andymccall not quite. There are some critical and subtle differences between the chips. Some software needs to be patched to work. Have a look at my hackaday project for some of the issues.

2024-07-21

@gilesgoat It's my design. Hence my surprised state of amazement when it works 😁

2024-07-21

Always amazed when it works - hand soldered another LQFP-100 ez80 CPU.

is it just me - or is poor hackaday.io being hacked? I hope they are ok.

I did see some spamming accounts flooding the site a few days ago with adds for fake doctor certificates!

@stefanie Thats really cool. Looking forward to hearing how it progresses. Cheers

2024-06-05

@stefanie Thank you. I am finding that the eZ80 is more popular than I initially thought. Would love to hear about your project.

I have hackaday projects, that details somewhat my progress: hackaday.io/dinotron

The ez80 stuff is still only a few days old. Have a fork of RomWBW project and a firmware project:
