RC2014 Pro Kit

• Site: https://rc2014.co.uk/
• Official store (EU): https://z80kits.com/shop/rc2014-pro/

The RC2014 Pro CPM Kit is a modular computer with an 12 slot enhanced backplane. It has a Z80 CPU running at 7.3728MHz, 64k RAM, Microsoft BASIC and SCM on ROM, or CP/M 2.2 on Compact Flash and communicates over serial at 115,200bps via a Zilog SIO/2 UART. The backplane allows expansion modules such as official RC2014 Modules or a selection of 3rd party “Designed for RC2014″ modules. The design is simple, and the standard 0.1” pitch headers encourages building your own add-ons.

64k RAM

CP/M: The Page Pin from the ROM needs to be connected to the Page Pin on the RAM.  If you have the Backplane Pro and have installed the double header pins supplied with that then nothing further needs to be done.

Configuration

All four jumers to right hand setting.
Top 3 jumpers set start address to 0x0000.
Bottom jumper sets lower 32k to be paged in or out from Pageable ROM board.

Note that the B option for BASIC will not work with this hardware set up. If you want to use BASIC from ROM set the A15 Page Selection jumper to 0. A better solution though is to download a copy of mbasic or BBC Basic to CP/M, which then allows you to use the compact flash card for storage
