Hi Emil, A brief not to say the IDE and IO cards are working, Using them withthe keyboard card allows me to auto boot into CP/M using the TMS/PS/2 combination, sweet.

I tried the xmodem flash firmware update today too all ok.

n.b The only LEDs I had eight of were the white SM ones seen here. I'm ...

I had a look on the Fujinet discord, the RC2014 version seems to be very much in flux with parallel, serial, and spi contenders.
I have an Apple II here for repair, I'm tempted to try and get it working with Fujinet - need to fix it first though.

I have not yet managed to get a CF interface ...

Yes XM was tested with MECB 6850. It didn't work for me without cts flow control at 38400 bps. Glad it's working for you now, David

Probably not much help but XM is working for me.

I'm using a FTDI ...

Hi Emil, it's a long while since I tried, but I remember having to use one of the Kermit implementations to get a reliable transfer. I have found some usb/serial adapters just don't work well for handshaking. I have an old ftdi based one which seems good if others fail

I have used John Hanson's t ...

It must be a year or two since I started this MECB to RC-Bus adapter board, but today its performed its first task. It allows my RC2014 8042 keyboard adapter to work with the TMS to form a CP/M terminal using Emil's Z80 configuration together with a small edit to the tms.asm to enable the keyboard ...

I had not heard of Fujinet until you mentioned it here. It looks ideal for a multi processor platform like the MECB. Here is an interesting development interface for Fujinet https://github.com/FozzTexx/fujiversal-pcb-prototype
There is an active community with a discord and other presences, David

I forgot to mention, I'm using a standard 4MHz Z80 with speed jumper set for straight through. I do not have a faster one.

I use CP/Net on my Z180 system with a wiznet module connected via spi on the SC126 board. I'd like to get that working on the MECB platform too. Here are the notes showing how ...

Some of Emil's Z80 boards arrived in the post today. I found I had everything I needed to build one and set about it. Then headed over to the RomWBW github and copied the instructions to patch the build with the modifications needed to support the 6850 ACIA etc. Everything seemed to fall into place ...

Hi, looking at the z80 schematic I wonder if it would be possible to incorporate the 7474 into the pld, Im not sure if it could but it would be nice if it could, it's simpler already without the other glue chips. D
