Hello. I bought a motherboard from Panasonic FS-A1F. I do not have a Keyboard. Gave it 5 volts and ground. The home screen appears.

But then nothing happens.

Is there a problem? Scheme this model not found in networks.

It's trying to boot a floppy that doesn't exist. If you find a way to attach a drive you'll probably boot successfully.

I can see a cable at the right, remember that the floppy used (if you're already using one) must provide the RDY signal and of course, it must be configured as A (DS0)

Should it still boot into BASIC even if no floppy (drive) is present?

It depends on the controller/Disk-ROM.

Connected the drive with RDY mod. But nothing has changed. The problem remained. Maybe it's something else. What other options are there?

Maybe you need a keyboard? Does anyone have the diagram of the keyboard ribbon cable?

It can be. Maybe someone with a FS-A1 can check if it boots with no keyboard...
Does the drive shows signs of life?, or is silent and no leds lightning?

And last but not least, do you know the PCB status?, is it in working order or is unknown?

Boot without floppy: Yes, but it takes a minute or two
Boot without keyboard: no problem, keyboard makes no difference.
