WTB: Apple II power supply cases from broken supplies

Submitted by jwg1962 on March 15, 2017 - 7:55am

Hey Fritters,

I am looking to buy a few Apple II power supply cases (II, IIplus, IIe, IIGs) for a project I am working on. I don't want working ones, only broken ones please, but the cases need to be in good shape.

PM me if you have some and let me know what you want for them.

Thanks,
Jay

AppleColor Rgb Monitor (For IIgs) Adjustment?

Submitted by Johnnya101 on March 14, 2017 - 3:52pm

Hi all,

I've looked many placed for a service manual for these, but never have been able to find one.

I just rendered the flyback, and replaced all the caps on mine. Since it's all apart, I'd like to adjust this to factory specs, as I'm sure it's out of adjustment.

I k of there is a built in screen for adjustments for example how do I go there?

Need a card identified

Submitted by CWJ_Wilko on March 14, 2017 - 12:48am

Managed to sweep up a trio of cards on eBay, including the Z80 card I was holding out for. Got a good price on it, would have paid that much just for the Z80 card alone.

So it's a Z80 card, a Disk II card and.. a mystery card! The D27160 is an EPROM but beyond that I have no idea. There is a two pin connector on the card that resembles the Apple II speaker connector - is it a sound card?

Is this real?

In the GS/OS Reference Manual, Chapter 10
is about Handling Interrupt Signals.

If none of the interrupt handlers accepts a given
handler it becomes an unclaimed interrupt.

Seems pretty strightforward right?

But there are possible causes for unclaimed interrupts
and I kid you not. This one caught my attention:

random transient phenomena such as cosmic-ray or

How to open a IIe/IIc joystick?

Submitted by Drignor on March 10, 2017 - 7:36pm

Anyone know how to open one of these things? It looks like these little plastic screws are the thing I need to get out, but they don't seem to move up at all when I loosen them. I don't want to break anything so I figured I'd ask before wrenching the thing open.

Has anyone seen these before? Just popped up on eBay for me, I've been looking at the cheapest possible solutions to getting CP/M on the Apple II:

Apple //c volume pot (did a bad one)

Submitted by CWJ_Wilko on March 6, 2017 - 4:57am

I've snapped my Apple //c volume pot when trying to 'repair' it. I have a nasty habit of making things worse before they get better. Does anyone know if there are any drop-in replacements? The plastic knob itself is fine, so I might be able to find something local or online that is close enough.

Does anyone know what resistance range that particular pot had?

I'll put in a request on the WTB forum just in case anyone has a genuine spare.
