RAM BOX

Revision as of 11:37, 1 August 2014 by TotO (Talk | contribs) (→‎Technical specs.)

The box

A 512KB RAM expansion made for CPC 6128.

Technical specs.

Partially compatible with dk'tronics memory expansions, it don't handle C3 mode. Note that A8 and A9 address lines are connected but not decoded. Those lines are only needed for up to 4MB RAM expansions. So, it's not a problem.
