Apple Computer Collecting

I'd say any of the technical books from Addison-Wesley are worth keeping. Ive got the BASIC programming with ProDOS and it's pretty detailed. There were so many neat options back in the day. For example, I've got a ][+ with a special 80column card designed for it that could run a patched version of Appleworks. It also had a replacement encoder board to do lowercase and had macro capability. Of course, the apple SCSI card is worth looking for. I've got one and tried to connect a drive and no luck. Will have to try again. The //c+ is pretty neat. I eventually got one, but they are not easy to find. If you can find a working Apple /// or ///+ get it. I lucked out and got a complete functional one with hard drive and original disks. And of course, the LCD display for the //c.
