This game has struck me as being an oddity.

I remember it being it in Hi-Res.
Which it is isn't?

Upon close inspection I noticed that it has
purple borders.(Assuming you have a colour
monitor or TV. Sorry for those that do not)
This is not Hi-Res, but Lo-Res.

How do you get Hi-Res and Lo-Res on the
screen at once?

C056 - select Lo-Res
C057 - select Hi-Res
C054 - Hi-Res Page 1
C055 - Hi-Res Page 2
C053 - Mixed Mode - Hi-Res/Text Mode ONN

Recommendation for a cool colour Apple II demo

Submitted by Corey986 on March 19, 2017 - 3:25pm

I need something self running.

I am planning on showing at VCF east the differences between a rev-0 Apple II and a rev-4 as part of my exhibit.

I am about finished completely rebuilding two identical Sony KV9200 trinitron TVs from the mid 1970's

Now all that is left is to decide on what to display.

Any suggestions????

Thanks,
Cheers,
Corey

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?

Submitted by wishtoknow on March 13, 2017 - 1:00am

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
