Super Serial Card not working, but not dead either

Submitted by maniac on September 4, 2017 - 7:27pm

I'm trying to resurrect an old enhanced IIe. So far, I've gotten everything working again, except for the Super Serial Card. I'm able to run a few diagnostic tools, all of which see it as an unknown card. APEX II sees it as: 44 80 168 184 56. The correct values for an SSC are 44 80 169 184 56, so it's only off by one. I'm wondering if it might be one bad chip on the board somewhere I could replace. I have a second old IIe motherboard, which I've already used to cannibalize parts and repair a bad RAM chip on the 80col card.

Picked up Apple II Plus, Apple IIe and two UniDisk drives; asking for valuation and identification

Submitted by alexlatham on September 4, 2017 - 12:04am

Hi everyone. I recently picked up an Apple II Plus with the raised power switch, Apple IIe, and a couple UniDisk drives as the previous owner was going to throw them away. I don't know much about earlier Apple computers. Either way, I took them home to see if they worked.

While I don't have any diskettes to test the UniDisk drives, they did do the normal floppy seek. Both models power on and display as normal.

Connecting the Apple IIc to a TV or LCD Monitor

Submitted by MaxTek on August 30, 2017 - 3:20pm

Is there anyway to connect the Apple IIc to a CRT TV, a Flat Screen TV or a Flat Panel Monitor. I have tried using an RCA cable many ways and can't get a single on any of the TVs or Monitors.

Thanks.

Strange problem with Apple IIc Please Help

Submitted by MaxTek on August 30, 2017 - 3:18pm

I have an Apple IIc and I can't get the floppy to spin up "unless" I unplug the floppy cable from the floppy drive slightly. When only 2-3 pins are making contact the floppy spins the disk very nicely and the red disk use light comes on. When I have the floppy cable plugged in all the way I can't get the IIc to make the drive do anything.

Any ideas? Thanks.

When I still keep enhancing my IIGS with TWGS, I wonder why there is not a system benchmark software for Apple II family, and do you wanna get one ？

Apple IEEE-488 Interface card

Submitted by tokabln on August 26, 2017 - 7:06am

Dear folks,

I'm looking to find some manual describing the function and set-up of an Apple IEEE-488 Interface card.
I searched the internet already but didn't find a PDF of such a manual.

Any help will be appreciated.

Many thanks and have a nice weekend

Another Apple II+ Boot Problem - UPDATED with Photos!

Submitted by 1978AppleII on August 26, 2017 - 1:06am

Yes yet another Apple II+ boot problem.

Before I get jumped on, I did search the forums and came up with 67 pages of possible links regarding "Apple II Boot" but none of them that I saw seemed to match this set of circumstances.

I am trying to help a friend get an old Apple II+ up and running. He received it totally dead and non functional.
