ZXMC firmware version 2.0

Hello caro The first post of the topic contains a new version of the firmware and a file describing how to work with a real-time clock. Changes: 1) Reading ports 00EFh and 00DFh returns version number of the current firmware in decimal format, for example: PRINT IN 239 or PRINT IN 223 prints 20 for this version. Returns in all previous versions value = 255 (0FFh). 2) Cosmetic changes to TinyTerm. see source. 3) The work of RTC has been adjusted in terms of support for storing the current value year (see ZXMC_RTC.DOC).
