I don't know much about > PETs yet but I'll answer what I can. I'm a relatively new owner of another PET in the 8000 series: an 8032 with the accompanying 8050 disk drive. I have put together a notebook with project material for what I'm going to do with my PET. (Some sort of animated character hack with hokey music, most likely!) I started with PDFs and JPGs of PET 2001 manuals that are online. The PET FAQ has lots of information on the entire product line of PETs, including the 8000 series. For firmware information, there is a memory map by Jim Butterfield that shows the locations used by BASIC and ROM "kernal" in the various PETs. You may also want to get a corresponding character map that shows the byte codes for various characters in the extended and graphics character sets of the character ROM of the PET. The PET Index by A. Fachat has some good info on the programming model of the PET. WinVICE is a good emulator and lets you emulate the specific ROM that you have in your PET so you can cross-develop code for the PET on your PC. For the 8032, I found a complete ROM analysis characterizing all the entry points and whether the location represented text, data or code. <http://www.portcommodore.com/commodore/pet/petwords.html> contains a description of the keywords in PET basic. I was also interested in assembly and chip coding the VIA, so I printed out information on the 6502 instruction set and the VIA chip. I also printed out some information on the IEEE-488 interface bus used by the PET. -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org> Message was sent through the cbm-hackers mailing list
