The 1240 is built around an [[Intel 8088]] as the control processor with 64K DRAM, and firmware in a bank of EPROMs. A separate I/O processor board is powered by a [[Zilog Z80]]A CPU. The display controller is built from individual TTL and ECL ICs. | The 1240 is built around an [[Intel 8088]] as the control processor with 64K DRAM, and firmware in a bank of EPROMs. A separate I/O processor board is powered by a [[Zilog Z80]]A CPU.
