After a little inspection it turned out to be an 1984 Sharp Personal Word Processor device. What does this mean? Well.. it's like an electronic typewriter with added functionality. It can either type from the keyboard directly on the paper with a ribbon tape printing system or it can be used as a word processor through it's 80x16 character display.
It looked to be in quite working conditions so after removing the old style power plug i gave it a try to see if it will power up and.. ta daa! It works! The display is graphical LCD with blue writing on white background. I was writing and printing a document in no time. The ribbon was as expected dried and very fainted but still visible. Letter "e" is missing from the letters wheel, but other than that all seems to be working fine. I can't test the floppy disk functionality as i don't have anymore those old type 3.5'' disks.
Next to the unit I also found the original manual in english. Surprisingly on the first page it stated "30 DAYS WARRANTY", i would have definitely expected more from something like this.
I love when i stumble ancient electronic stuff like this and I always end up to pretty much the same conclusion: things were done better in the past, before all this consumerism era.
