Fantastic - thanks for the update David. LOL, you may need to wear sunglasses (or welding mask) when looking at those LEDs :-)

I've made up a PS/2 keyboard board (compatible with RC2014) and am just waiting for the parts to arrive to test it. I'd also like to try my hand at building a C64 SID ...

Not the most beautiful set up ... but finally managed to test two IDE drives connected to the same card. In this instance I had a Compact FLASH to 44-pin IDE adapter board (set up as a slave) and a Compact FLASH to 40 pin IDE drive adapter (set up as a master). I can't imagine ever needing so many ...

Hi David,

Perhaps the faster 10 MHz Z80 I have on mine helped to push it over the line for 38400 usage?

By the way, I connected up to the Fujinet discord group. It looks like there is still quite a bit of discussion with respect to how to implement the interface to the ESP32 device (which does all ...

Ha, looks like it is something weird with minicom - I just tried it with CoolTerm and it worked fine even without any flow-control.

Thanks for helping me debug this - at least I know it is not something weird with the MECB hardware or software now

Thanks for running that test. Just to check was this running on the MECB Z80 with the 6850 serial connection or on the RC2014? I just tried via a Raspberry Pi and had the same issue. I'll try and get CoolTerm just to ensure it isn't some weirdness with minicom.

Thanks David,

I do have some alternate serial devices on order which I'll try once they arrive. It just seems strange that it doesn't work without hardware hand-shaking i.e. I can load software via the monitor with no problems. Of course, there might be extra overheads involved with XMODEM (I'm not ...

David, Seeing as you are familiar with RC2014 ... is there a trick to getting XM.COM working? I was able to send a file from the CP/M system to my laptop but for the life of me I can't seem to go in the opposite direction i.e. send a file from my laptop to the CP/M file system (which is the ...

OK, managed to check the 40-pin interface as well (I had a Compact FLASH interface on an old 486 PC that had the 40-pin adapter ... I just had to make an appropriate power cable for it). I had never previously noticed that this cable also had pin 20 blocked (to act as a key - despite having the ...

That is very cool David!

(Sorry for the slow response, I was travelling over the past few days and only just got back)

Having a bus converter like that would be great for testing alternate devices that are already available on the RC2014 system on the MECB system! Funnily enough, I just received a ...

I've received the V1.0 PCBs, built them up and confirmed that they now work fine. All of the updated files and PLD definitions are on my GitHub:

NOTE: The one aspect I haven't tested is the external front panel interface (which is connected via ...
