It was my first job, and this CBM 3016 were extended to 32Ko RAM like the CBM3032 model.\ I did many interface boards for this model and many programs in 6502 assembler too. author date text Yves McDonald (the North, Quebec, Canada) Monday 8th May 2006 Well, at least you know the video circuits are working. Looks like the CPU isn't resetting right and isn't executing its code in ROM and fails to clear its video RAM. I had same problem with old Apple 2. It's probably just some corrosion build up on chip leads or sockets. Cleaning up the contacts with a soft pencil eraser and/or reseating the chips will be enough to restart your vintage computer.\ Hope that helps. author date text A Hodson (England) Friday 6th February 2004 When I switch my PET on the screen is full of rubbish. It used to work fine sometimes but not now. Can it be fixed? /museum/commodore-cbm-500-600-series /museum/commodore-cbm-700-series /museum/commodore-cbm-80xx /museum/commodore-pet-200 /museum/commodore-pet-2001 /museum/commodore-pet-cbm-40xx /museum/commodore-superpet /software/space-invaders-669 102 url date https://web.archive.org/web/20230601095109/http://www.old-computers.com/museum/computer.asp?c=102 2023-06-01

The CBM 3xxx and 4xxx series were revisions of the original PET 2001.
The range was rebranded CBM (Commodore Business Machine), as PET was dropped.

The 3xxx series introduced the 3000 series ROM sets, BASIC v3, and a completely redesigned keyboard layout, which used a full typewriter keyboard instead of the "mickey mouse" keyboard of the PET, and dropped the on-board cassette unit.
