/* Third schematic Z80+ROM+RAM+VGA */
To solve this problem you can use a special RAM done for this problem, a RAM that you can WRITE at a certain speed, and READ at another speed, this magic component is called '''ramb16_s16_s16'''. Note that they have no problem to write simultaneously on two RAM components, so that you can dump video RAM content using starter kit RAM, and you can display VGA using FPGA internal '''ramb16_s16_s16''' RAM.
