Donor note: "The microbee is a computer from Applied Technology (And later Microbee Systems) that was released in 1982 in "Your Computer" magazine for about US$ 350 as a do-it-yourself kit. Comes with 16K RAM, battery backed and BASIC (non-Microsoft) with some graphics capabilities based on a Z-80. It could be later upgraded to a Z-100 bus and later 512K with disk controller by the replacement of the memory board (the keyboard was on the main board, and the memory board sat on it, sort of like a large ZX-80 with real keys. Microbee systems went bankrupt in the 80's with a computer that would have run CP/M, UNIX and DOS on one computer. The newer microbees ran CP/M with a memory drive, and was the only CP/M in the world to run Wordstar 4.0! They even had a sort of WYSIWYG word processor . They also ran Turbo Pascal versions 1-3. They have a standard composite video output and can be plugged into any VCR or a CGA monitor on the newer color model. "
