This may be the earliest model off the production line you'll find. NOT the 6003 A model, the original 6003. Check out the serial number - 001344 !!! If you're truly collecting vintage, this is the one.
Unfortunately no box, no instructions, no disk. Modem is in good shape - untested. A few minor dings, labels a little scuffed.
Follow my account or watch my listings for other vintage Commodore manuals- both product and reference/learning. I'll be listing over time manuals for programming, diagnostic service manuals, in addition to manuals for disk drives, printers, etc. I have a lot of Commodore gear I'm letting go of including software, accessories, chips, and specialty items. It will take some time to list it all, along with other things I buy/sell. Thanks!
