Z80-MBC2 Vs Z80-MBC2 Limited Edition

The Z80-MBC2 Kit went on sale for the first time in 2019, until September 2021 we kept the same price until we ran out of stocks of the components in our warehouse.

In recent months, many components of the Kit have also increased in price by 200%, and for this reason we cannot maintain the same sale price as in 2019.
We decided to make a new configuration of the Kit, thanks to the suggestions and advice that some customers have written to us to improve the Kit.
We called it Limited Edition because it is a limited batch of only 100 pieces, 50 pieces in the Tin version and 50 pieces in the Gold version.
The Tin version is an economic version, while the Gold version uses some components of greater value and cost.
As the price of the Kit components varies from day to day, when this lot is sold out we will make a new lot with an updated sale price.

Update October 2023

The market has overcome this period of crazy prices and prices have almost returned to those of 2019.
We put the Kits back on sale in a series with cheap but good quality components and called it the Blue Edition.
So the Z80-MBC2 is now part of the Blue Edition series
The Z80-MBC2 Limited Edition Tin has been put back on sale in the Black Edition series

The Z80-MBC2 Black EditionV20-MBC Black Edition and 68K-MBC Black Edition Kits are now sold with Black micro SD card and RTC modules made by Mc John S.r.l.
