The Convergent Technologies WORKSLATE! Used the Motorola 6800 processor, a printer that actually drew the characters with a ball point pen!, 64K of memory (mine upgraded to 128K), a micro-tape cassette for storing data, a build-on dialup modem (300 baud), and only ran one program: Visicalc spreadsheet. LCD display only. First offered by mail to American Express customers for an even $1000 in 1983.
One of the first AllInONes, it also had a telephone answering machine built in, plus a voice recorder with a built in microphone. I still have it, along with the original box and all the peripherals. Waiting for it to appreciate [g].
