Booting a Macintosh Plus 1MB

[JonDane]

I have just brought out a Macintosh Plus 1MB from the attic which I last used in 1989. It has no floppy disks or hard disks with it. On power-on, it beeps many times and a bright spot appears in the middle of the screen. I have removed the corroded AA battery from the rear and have not replaced it.

If I bought a boot disk, e.g. " Macintosh 800K Boot Disk - System Software + Games (for Plus, SE, Classic)" from eBay, do you think that it would boot or do you think that the symptoms that I've described indicate something wrong?

I live in Henfield, West Sussex, near Brighton, England.

I would be very grateful for advice.

A greater concern is that bright spot in the middle of the screen. That’s definitely not normal and could indicate big internal issues.

Thank you.

There's a classic Mac section here at MacRumors where you might find more help.

There's also a website called:

Low End Mac: Make the most of your Apple gear

... where you might find answers.

Other thoughts...
Put a replacement battery in. You want that.

I had a Mac SE (not a Plus), but I recall that a common problem with the Plus was a failed power supply.

Could also be bad contacts (dirt, tarnishing) between RAM and RAM slots. It's been so long, can't remember if the 1mb had removable SIMMs or not...
