I got Apple IIc with monitor, but am having problem with using it. Computer starts ok and boot from disc drive. I have discs that say Prodos. But if I boot with those it goes to something that look little bit like machinae language monitor.. Readed manual about commands like car and catalog, but couldnt even list directory.. What should I try next..

Are you trying to get into basic? I think the apple auto-boots on startup, but if you press apple(ctrl?) + break, or something like that it'll just go to a prompt.

from what i remember you had to reset the Apple after start to get the command line or something.

or that could have been for earlier models..?

IIRC... but that's a big "if"...

Unless there is a disk in the drive at startup, the computer automatically goes to Applesoft BASIC. When you see the "]" it means that you are there.

The disk operating systems (DOS and ProDOS) were disk based and were usually loaded by having a disk with the disk OS in the drive at startup. When the disk OS was loaded, you still got a "]" prompt for BASIC and disk commands.

It has been a long, long time so I'm not sure I'm completely correct...

Late post to a long dead thread...

On any Apple IIe/IIc machine you can run the built in memory diagnostics by pressing ctrl-open apple-closed apple-reset

It will show you what memory chips are bad. If it has an * beside it then it's one of the upper 64K bank that's bad (on the 80 column card on the IIe)

Bad news: It stops as soon as it finds an error so you have to replace that bad chip then keep running the diagnostics until it comes back with no errors.

TIP: If you unplug the keyboard and turn the system on it will loop the diagnostics repeatedly until it finds an error or until you turn it off. It's a good way to do a burn in test.
