I suppose you could design a Homebrew SAM Coupe with only a handful of
Z80 CPU (possibly Z84C0010PEC 10MHz)
EPM9320 Glue Logic, Video logic, Memory decoding etc
MB8877+WD9216 FDCs ?? These may be compatible with original SAM Disk Drives
8255 PIO for IDE interface (Hard Drive or CF Card )
There wasn't a lot of ICs in the original anyhow !
