A couple of firsts for me (Commodore)

Well, a friend whose moving was digging through his attic and found the families old Commodore 128. This is the first time a friend has ever given me an old computer, I think. It's also the first Commodore in my collection. I had sort of been avoiding Commodores since my only experience with them was with my old Vic 20. I had fun with it, but I wished it had been an Apple //e..... that's what I really wanted. I eventually got an Apple //e and used them in school, too. I got the C128, and a 1581 floppy drive. No monitor and no software, unfortunetly. The other day, I saw a Commodore monitor at Goodwill, along with another model floppy drive. I think I may go pick those up tomorrow. Does this have an OS in Rom, or does it need a "boot" disk like an Apple //? I like the slim design, although and internal power supply would have been nice. I think I like the was the Apple //'s are built, better. The C128 was kind of difficult to disassemble. I actually had to use a soldering iron..... something I've never done while disassembling a computer. Chad Fernandez Michigan, USA
