Apple Power Requirments

Submitted by apple2lives on March 12, 2013 - 8:34pm

An interesting topic arouse in a different post. This leads to the question what are the power requirements of an Apple II computer? I thought this might make an interesting forum topic.

I do not know the accuracy of these numbers but they were published by Applied Engineering. All values are in milliamps and only apply to the +5V rail.

Need some help identifying Joystick? “Apple stick”

Submitted by transwarp II guy on March 12, 2013 - 2:01pm

Hello, does anyone recognize this device? I’m guessing it’s some sort of I/O device but I don’t want to plug it into my II’s 16 pin I/O port in fear of possible damages.

I just purchased it off of ebay, the pictures are a copy from the listing, I can take better pictures if anyone wants me to. By the way thats a film container over the 16 pin plug.

Any help will be highly appreciated! Thank you.

Heres what it looks like:

AppleColor composite monitor problem

Submitted by dramsey on March 11, 2013 - 8:39pm

I just received an AppleColor composite monitor, model A2M6020, and it has a little problem: everything displays as purple.

Well, it can do blue and orange as well. But 80 column text? Purple. White lines? Purple.

The tint, color, and "white only" button on the front of the monitor have no visible effect on the display.

My guess is that the green electron gun is kaput and that there's no reasonable way to repair it, and I should probably send it back. Opinions?

Spontaneous reboots due to overheating?

Submitted by dramsey on March 11, 2013 - 4:34pm

After a couple of hours of Pascal work on my //e, it starts to spontaneously reboot. After the first reboot, you can sit there, doing nothing, and it will reboot at 5-10 minute intervals.

It seems to run fine with the lid removed, so I suppose it could be a heat related problem. My system has:

-- Applied Engineering RAMWorks III card with 1MB RAM
-- Applied Engineering Transwarp accelerator
-- Super Serial card
-- Mouse card
-- Disk II controller card

UCSD Pascal RAM disk for AE cards

Submitted by dramsey on March 10, 2013 - 4:15pm

It turns out it does exist after all, although not in the otherwise excellent Applied Engineering Repository. You can find it on ftp.asimov.net here:
