No issues. Works Fine

I got the black edition. This is a high quality kit that contains everything you need using Teraterm or putty as a terminal.

Having fun with the Z80-MBC2

I have gotten into the retro computing scene with the Z80-MBC2 Black Edition kit, and have been having quite a bit of fun with it. I got into computing way back in February 1977, and building this kit brings back the fun that has has been lacking since the days of IBM PC style computing in the 1990's. I enjoyed soldering this together, and running CP/M and other retro software and games. When I ordered this, I also ordered the uCom Back Edition to go with it, and that is also a great and enjoyable kit.

Perfect kit with all its components, easy to assemble and use.

I ordered the kit fromn France on November 9, 2022 and received it on December 1. <br /> Very good kit delivered well complete. All parts are grouped by categories in separate pockets. <br /> It was a great fun to assemble it, and pictures on this website were a good help. I am very satisfied with this purchase.<br /> But during assembly, pay close attention to the polarities of electrochemical capacitors, LEDs, diodes and resistor networks.<br /> For the electrochemical capacitors in the kit, the negative leg is near the red mark, and on the pcb the square pad is the positive side.<br /> For the two resistor networks, the leg near the indication is the common leg to be inserted in the square pad, but it's best to check with a multimeter.<br /> For diodes and LEDs, unlike capacitors, the pcb square pads are negative sides. The negative leg of a LED is the shortest, to be insert in the square pad.<br /> A K letter is Near each square pad of LEDs. K for Katode (cathode), négative side. <br /> After soldering the polarized capacitors,take care not to put LEDs in the wrong polaritie. The serigraphy of the diodes avoids the error.<br /> No difficulty for the resistors, but checking their values with a multimeter is more safe. No problem with the other components.<br /> After connecting the card to a USB port, some diodes flash, which is a good sign.<br /> Then check, in the device manager of the computer, that the Serial-USB module is detected, and that a com port number is assigned to it. Note this number.<br /> If no com port appears, search for a suitable USB-serial driver on the Silicon-Labs or Prolific websites for example.<br /> Windows 11 does not have the correct driver by default, I downloaded and installed CP210x_Universal_Windows_Driver.zip from Silicon-Labs, it works perfectly.<br /> Then launch Putty (or another serial emulator), configure it as a serial monitor (115200 8 n 1) and indicate it the noted port number (com1, com2,..).<br /> Run the correct configuration. After a scrolling text, appear the cp/m disk A> .<br /> <br /> The red diode D1 (HALT) never lights up. It's normal.<br /> To test it, run this short program in MBASIC. You can only type lines 100 to 500<br /> <br /> 10 REM Test Halt led (D1) of Z80-mbc2.

Z80-MBC2 Black Edition Kit

Received the kit shipped to the UK in just over a week. The kit was excellently packaged and components separated into relevant categories. Enclosed paperwork had schematic, placement diagrams and bill of materials. All components were leaded and easily identified. The enclosed SD card had all the relevant software pre-loaded. I connected the board to a computer using the enclosed serial-USB adapter. I mounted the board in my own enclosure using a USB bulkhead adapter in order the get the serial connection, this also provided the power to the board. The board has provided me with lots of memories having run CP/M in the 1980's. Later I purchased the uTerm Black board (see separate review) to provide a PS2 keyboard input and VGA monitor output so the serial to USB adapter is no longer required for day to day use but can be connected on the serial output on the uTerm board if required.
