True, it's purely a boot loader and not a BIOS. I can't think of any other home computer without a BIOS. Maybe a very early home PC like the Altair 8080. I don't know if those things even had a boot loader or if they had to be bootstrapped manually through the front panel.
Unrelated question:
The ribbon cable connecting the computer to the keyboard was getting frayed so I removed it and replaced it with a new one. I foolishly thought the connection was 1:1, that pin 1 would go to pin 1, 2 to 2, and so on. I realize now that isn't the case. I tried rewiring it using the following diagram but it still doesn't work.

But that keyboard seems to have some active components on it whereas mine doesn't, just switches and a couple of LEDs. Is the pinout different for reed switch keyboards?
