Apple II test programs

Submitted by pyrex8 on November 12, 2020 - 11:06pm

I'm looking for some test utilies to compare the performance of Apple IIe and an emulator. I'm really interested in sound and graphics utilities.

1. A sound test, something that plays tones from a low frequency up to the highest that an apple can reasonable output.

2. Some split screen graphic tests. I found this demo which doesn't seem to work on the copy of LinApple on my machine. http://www.deater.net/weave/vmwprod/split_demo/

If anyone has ideas or recommendations I would appreciate it.

//c Power Brick Parts

Submitted by nick3092 on November 10, 2020 - 3:49pm

Has anyone ever cracked open one of these bricks to see what's in them if someone needed to repair one? I have a spare one in working condition. I'm thinking about opening it up and seeing what's in there. I imagine at the minimum there is a transformer, diode bridge, and a filter cap (that eventually would probably need to be replaced).

Suncom Party Quiz Controllers

Submitted by nick3092 on November 10, 2020 - 3:46pm

I just bought a set of the Suncom Party Quiz controllers/interface/software. I noticed on the box it says only 2 of the 4 controllers work on the //c. It plugs into the joystick port.

 

Is the limitation on the number of controllers due to the fact on the //c the port is shared with the mouse?  As opposed to the IIe that had a seperate 9pin port for the mouse? It looks like for the II/II+ it also has the dip style game connector, probably wired in parallel to the 9pin connector that run to the interface box.

Apple /// external drives problem

Submitted by Kingpin on November 7, 2020 - 10:23pm

I have 2 x external floppydrives. If I connect any of them all is fine and they come up as drive 2 and pass tests etc.

 

If I "chain"-connect either of them I get odd results. One drive comes up as drive 4 and the other one doesn't even come up as drive 2 or 3 in that scenario. Also, when accessing the floppydrive both motors and LEDs starts/lits up.

Anyone who's seen this or similar problems when using more than one external floppydrive?

 

Thanks!

Original Merlin

Submitted by decuser on November 6, 2020 - 8:36am

Hi, new forum member here. I'm looking to see if anyone can shed some light on which version of Merlin to use on Virtual ][. I'm preparing to buy an Apple //e for real and want to ramp up to programming on it via Virtual ][. I have found several version of the assembler and don't really know how to compare them - they all kind of look the same to me :). I watched this video:

So I have a monitor /// with a good CRT but I need a CRT Board /Analogue board to repair it. The one that came with it was physically broken and damaged (it was stabbed, dont ask.)
