I'm sure many of the old hands around here will know these already, but for those who don't yet or may have forgotten, this may come in useful.
ZX81 with ZiLOG Z84 CMOS Z80, 32KB battery-backed Toshiba 55257 SRAM with charge status LED, Wilf's "Why Wait?" mod and switch-mode 5V regulator. 50/60Hz mode switch, composite video output with Zigg's back porch mod and 1080p60 HDMI output.

Best saving is coding in machinecode and stop coding in BASIC.

As an additional comment, if you don't need floating point or flicker free running screen, ZX80 basic is both more efficient on memory and much much faster!
