only HEX input "keyboard".
Micro Professor ? [Z80/A 2KB RAM, hex Keypad, 7 seg display, beeper, string of led lamps, fitting inside a VHS cassette style case].

Apparently, Micro Professor (originally by what was to become Acer) is currently still manufactured(later version):- https://en.wikipedia.org/wiki/Micro-Professor_MPF-I
[Above looks different to how I remember it]

Hewlett Packard LabPack, was similar but much larger in a Samsonite brief case (with additional 8 bank toggle switches as well as hex keypad).
EDIT: "8 bank toggle switches", why use hex, real real men use binary.

IBM Personal Computer 5150, 8088, 16KB RAM (Max 640KB), PC-DOS 1.0:- http://oldcomputers.net/ibm5150.html

EDIT: HP LabPack, actually looks like this one "HP 5036A MicroProcessor Lab" [although the one I remember had big toggle switches, not small DIP switches, and a lot more chips]:- http://www.hpmuseum.org/cgi-sys/cgiw...cgi?read=93495
EDIT: Took about an hour to key in a program to light up LED's in sequence and play a whooshing sound, like a rocket, time well spent, maybe.

EDIT: To Asarian below:
