Apple II

Hi, I bought a vintage floppy disk of Frogger for the Apple //e. It was still shrink wrapped with the original Our Price Records price tag which was pretty cool.

I had nostalgic fun opening it (couldn't resist) but the disk just boot loops.

It displays a one line copyright notice at the top of the screen for a millisecond:

"SPIRADISC (TM) SYSTEM (C) 1982 BITWORKS"

Then says "REBOOTING" and cycles like that.

The label on the front says "II/II+" and of course I'm running it on a "IIe" so I suspect that's the issue. I only just got the machine, and the one and only other disk I have (An Introduction to the //e) loads fine.

The weird thing is though, I used to own exactly that same game in the 80s and it worked fine on my //e!

Another programming question, maybe beyond the scope of this forum....

So I'm taking on a huge project... to develop an ONERR routine (in assembly) for Integer BASIC. Yeah. Who hasn't done this before? My plans so far are:

1. Understand what's going on with Applesoft's ONERR GOTO/GOSUB, which somehow also handles DOS 3.3 and ProDOS errors.

I have 3 Apple II joysticks. Two of them are the standard joysticks made by Apple with the thing stick and two buttons. The other one is a CH joystick with a button on top of the stick and two more buttons at the base. The CH stick also has a 2 connectors one it, one to plug into an Apple II and the other plugs into a PC.

Anyway, each one of these sticks has a problem, mainly, mainly with the buttons. The buttons don't work every time you push them or you either have to push them real hard.

I haven't taken them apart yet to check them out and I thought I would seek out some advice first. So here goes my questions. Will taking them apart and cleaning them up do any good? Is there anything I can do on my own to get them going again? Or do I need to get some replacement parts? If I do need parts, what would I most likely need?

Thanks,
Jeffrey
