RAM

128KB internal contentioned video ram

Hi density disk interface with DMA

Submitted by roger.j on Tue, 2018-02-20 14:33.

hi density disk interface for the zx spectrum includes a DMA which means you can have 8 pixel attributes just like mode 2 on sam
anyone know how to get extended density support please?
