A2S1 Keyboard nightmare

Submitted by falter on March 1, 2014 - 8:52pm

Guess I had it coming.

I realized I had the materials to make my own keyboard ribbon cable to replace the broken one that came with this A2S1 keyboard. No problem - followed the wiring schematics I had.. etc. But, alas, didn't work. So I switched back to the cable from my II+ and to my horror, none of the keys were working except Ctrl-Reset.

stuck key

Submitted by jeffreybritton on February 26, 2014 - 9:25pm

After finding which key was sticking on my Apple II e sprayed it with electrical contact spray to loosen it up. No luck. Not sure now if it is not so much stuck as broken. When I hit the key it makes a spring sound and the stem vibrates on release as seems very wobbly. What can be done to get my computer operational again?

Really early Apple II+ ?

Submitted by falter on February 23, 2014 - 2:53pm

I'm guessing this one must have had its board replaced. Very, very low serial number. Silver power supply like a regular II, but the board, I think I can make out the silkscreening on the left somewhat. So must be 820-0044-xx or something? Probably should be a Rev 03 or 04? Wonder what it'll hit.

Revisions of revisions?

Submitted by falter on February 22, 2014 - 10:42pm

Just a general interest question. Recently I learned that even within revisions of Apple II motherboard, there were sometimes mini revisions.. like the black slots on my Rev 04. I'm wondering if there are also notable changes with the other revisions that are of ajy significance? Thinking I might keep this Rev 04 board and start trying to collect all the variations I can.

Rev 04 vertical hold

Submitted by falter on February 22, 2014 - 12:44pm

I'm having a minor but irritating problem with my Rev 04 board. In diagnosing my Applesoft ROM problem on my RFI board, I had been swapping chips with the Rev 04 and had a situation crop up where there is no vertical hold.. the screen contents keep rolling upward. You can stop it with very precise adjustment of the vertical hold on the monitor, but of course this doesn't hold for long.

Repair or replacement parts for Apple II+ keyboard

Submitted by falter on February 21, 2014 - 11:33pm

I have one of the all in one keyboards for my Apple II+. I repaired a broken key stalk but have inadvertently wandered into a problem. A couple of the metal tabs broke off and Inam wondering if there is some way to repair them or if there is a way to get replacement parts. My 1 and 2 key do not work, and the key I repaired (right arrow) doesnt work either.

I did google amd search around on this but hadnt found anyone who was dealing with broken metal. Any help is greatly appreciated!

Apple II+ not posting

Submitted by falter on February 19, 2014 - 8:19pm

I decided to go after the keyboard issue in my II+ again. However now when I power it on, I get a screen full of this:

??@@??@@??@@??@@ etc.. with the @@s in reverse video. If I cycle the power, sometimes I get flashing > or other symbols at random spots. I thought maybe CPU, so changed that to known good, but no dice there. I know the ROMs are good and am confident the RAMs are ok... where do I begin on this one? Smile

Really stupid Apple IIgs keyboard compatibility question

Submitted by Eudimorphodon on February 19, 2014 - 12:20pm

A while back (better part of a year ago?) I posted about having a IIgs with what appears to be a blown keyboard controller. (And is still blown.) This weekend I was given another IIgs (also a "Woz Edition", I assume it's ROM01, and again just the system unit) which I have yet to power up. Here's the situation:

Apple IIe Enhanced logic board work with a PAL Apple IIE power supply?

Submitted by robbo007 on February 19, 2014 - 7:18am

Hi all,
Can anyone confirm that a US Apple IIE enhanced Logic board will work with a PAL European Power supply?

I know the Apple IIGS works without any problems but not sure about the Apple IIe.

Thanks,
Rob
