# Spectrum Machine Code on the 2068

Reprint from SYNTAX Magazine (Dec. 1983) explaining how to run ZX Spectrum machine code programs on the TS2068: replacing IN keyboard scan routines with INKEY$/STICK commands, and the importance of RAMTOP placement. Notes that programs written for 48K Spectrum are more likely to be compatible.
