It read data from the "Lower RAM" (0x4000 to 0x7FFF) and converted it into signals for a television.

If you want to replicate the magic on an FPGA or CPLD today, here is the functional spec: It read data from the "Lower RAM" (0x4000

" by is a seminal work for retrocomputing enthusiasts, offering a comprehensive, transistor-level deconstruction of the Sinclair ZX Spectrum's custom heart. Published in 2010 by ZX Design and Media , it serves as both a historical record and a practical technical manual for designing 8-bit hardware. The Role of the ULA (Uncommitted Logic Array) offering a comprehensive
