/* First schematic : Z80+RAM+ROM */
=== Minimal Amstrad Architecture : Build your own Z80 Amstrad Computer ===
I explain here my first great experiment, having Amstrad saying hello :)
==== First schematic : Z80+RAM+ROM ====Z80 can address from 0x0000 to 0xFFFF
*When Z80 do READ MEMORY, you read ROM *When Z80 do WRITE MEMORY, you write RAM*When Z80 do WRITE IO, you do nothing *When Z80 do READ IO, you response it DATA=0x00
When Z80 do WRITE IO, you do nothingrun this schematic on FPGA, RAM change !
==== Second schematic RAM+VGA ====
With JavaCPC, when you do a snapshoot, and hex edit result file, you see RAM content starting at a certain address.
