Works fine, best quality and packaging!

I got the kit and after 2 hours it was finished and works out of the box, ready to use a time machine to the Z80 days in my former life. Well done!

Fantastic kit, great attention to detail

This is a very complete kit, and includes details like LED spacers, an insulating pad for the crystal, and a red push button for reset. For my build, I used machined pin DIP sockets instead of the stamped sockets included in the kit. It worked on the first power up, booting right up into the CP/M. I really like the ROM and I/O emulation using the microcontroller, it is a very clean and extensible design.<br /> <br /> I also built the V20-MBC and had a similar positive experience. As a result, I just ordered the 68K-MBC and look forward to building and experimenting with it.

Great kit, highly recommended

Fast shipping with tracking, good packaging, everything included (even battery and SD card ready to use). Easy to assemble, but if this is your very first kit, take the time to study which components go where.<br /> Having a picture of the finalized board on screen while working is helpful.<br /> Several nice OS options on the included SD card gets you started right away.<br /> My system worked perfectly from first power-on.<br /> The SD card "disk" system is a nice replacement for floppies and winchester disks! CP/M 3 is an excellent OS for this system.<br /> I bought this kit because of the easy access to create new "ROM firmware" with the ATmega solution, rather than having to flash physical EEPROMs.<br /> Performance is as expected from an 8 MHz Z80 CP/M system. The SD card I/O is a little bit slower than similar Compact Flash-card solutions used in other Z80 SBCs - but nothing to worry about! It is still *way* faster than the 8" floppies used in 1979 :)<br /> Highly recommended kit, excellent quality.

My first soldering project - Good kit

It is my first soldering project. I took the time to solder each item.<br /> It took half a day. but it worked on my first power-on.<br /> <br /> I have not used serial communication since college. Kind of refreshing to use legacy technology. <br /> <br /> I will play with this Z80-MBC2. I have ordered v20 version too.<br /> <br /> thanks.<br /> <br />

Great kit, but missing PCB

This is a great kit, and was shipped quickly (five stars). Three stars for Quality because my kit was missing the PCB. I sent an email describing the problem and got a next-day reply. The missing PCB was shipped the following day, and I received it a week later (priority shipping to USA). Great customer support (five stars).
