  • Up to 64k of RAM
  • Pageable Lower 32k RAM
  • Selectable start address
  • Standard Bus – Single row header pins
  • Enhanced Bus – Double row header pins
SKU: N/A Category: Tags: ,


This is the 64k RAM module which is supplied with the RC2014 Pro or RC2014 CP/M Upgrade Kit, although it can also be used as a replacement for the CPU module supplied with the RC2014 Classic II, or if you are building your own custom RC2014 variant. It can be used with Standard Bus backplanes (Backplane 5 or Backplane 8), or with Enhanced Bus backplanes (Backplane Pro). If the Standard Bus option is chosen, then a 10 pin straight header is also supplied.  This will give you access to the PAGE signals.

This listing is for a kit of parts to build the 64k RAM module only. For the rest of the modules, see my other products.

This module allows up to 64k of RAM to be used (The full addressable range of the Z80 CPU). To avoid overlapping with ROM, the start address (and therefore usable size) can be set via jumpers. So, for example, if you are using the MS BASIC ROM that ships with the RC2014, set the jumpers for the RAM to start at 0x2000 (8k) which will give you 56k of RAM.

In order to run CP/M, the lower 32k RAM can be enabled or disabled via a PAGE pin driven by the Pageable ROM Module.

This module can be supplied as a 32k kit. This will work exactly as the 32k RAM Module supplied with the RC2014 Classic II kit does.
