It is equipped with a Z80 CPU, 1 KiB of RAM and 2 or 4 KiB of ROM containing a simple debug monitor.
Two 8-bit I/O ports connect to a 20-key keypad as default input and a 2-digit 7-segment display as default output.
You can also attach other peripherals to both I/O ports.
The board also includes power supply sockets and on/off and reset switches.
The reZet80 SCOUT is the little sister / brother of the reZet80 PIONEER. If you need more RAM or ROM or better expansion capabilities use the reZet80 PIONEER.
A minimal amount of NMOS and LSTTL chips that were available in the mid to late 70s are used in this project:
- Zilog Z80 (CPU, NMOS, 1976)
- Intel 2114 or compatible (1K x 4 bit static RAM, NMOS, 1976)
- Intel 2125 or compatible (1K x 1 bit static RAM, NMOS, 1976, alternative to 2114)
- Intel 2716 or compatible (2 KiB UV erasable EPROM, NMOS, 1977)
- Intel 2732 or compatible (4 KiB UV erasable EPROM, NMOS, 1978, alternative to 2716)
- 74LS139 (memory and I/O decoding, LSTTL, 1975)
- 74LS244 (input and output ports, LSTTL, 1976)
