🇺🇸 Osborne 1: Part 1 (Quick Look) [TCE #0501]
35Let's have a quick look at this Osborne OCC1 computer from 1981, a luggable Z80-based machine with 64KBytes of RAM, dual 5¼" floppy drives and a built-in 5" monochrome screen.
It only runs on mains power - as this one has come from the US I need to use a stepdown transformer to power it. It has an interesting array of ports on the front - full featured really: an external battery (DE9 socket), video output (edge connector), IEEE488 port, RS232 serial (DB25) and a modem port ... with modem.
This particular machine apparently couldn't boot from the disks, but at the moment it doesn't seem to be showing any output on the screen either. It has travelled from the US so maybe something has come loose within the machine ... not that I needed much excuse to open her up.
{Update: watching some other videos it seems that I either need to install a shunt on the "EXT VIDEO" port to connect the top-side signals to the bottom-side of the board ... or I should've installed the external video out dongle that it came with!}
