Need Mfr & Part# for Power Supply male socket that mates to Apple II MB female socket

Submitted by cfkerchner on February 28, 2021 - 4:23pm

Hi all,

Looks like my power supply is dying again. I'm looking for the name of the manufacturer and part number for the male socket that is on the colored wire bundle that goes from the Apple II+ PSU to the motherboard. 

I did see just now, that there is a connector assembly for sale on eBay from a salvaged PSU unit with the colored pigtails still on it, but they want $32 plus shipping. That is an extreme over price if you ask me, for just a pre-assembled (or should I say cut off a blown PSU) connector assembly. But that's the law of supply and demand I guess.

I'm in the process of reverse engineering a "mystery" serial card. This is a card from the early/mid 80s driving an original ImageWriter needle printer:

I'm planning to build these:

https://www.tindie.com/products/option8/retroconnector-joystick-interface-for-apple-ii/

 

I'd just buy them.  But I don't think he's going to be making more any time soon.  So I plan to make them.  The gerber files are on github.  But there's no bill of materials.  And he's not responding to me.

DIY Ethernet for Apple II+ and IIe

Submitted by Stargeezer on February 26, 2021 - 9:44pm

Evening All:

I want to play around with getting my Apple II+ and IIe on my home network and eventually Internet.  I know there are cards out on eBay and Uthernet cards, but I was curious how others have experimented with this.  In addition, I have some empty prototype boards and could, possibly, build one.

I have to admit I haven't done much research yet, but thought I would ask the community what experiences you have had and any do/don't suggestions.

Cheers,

mark

ProDOS Will Not Work on My 64k Apple II+ with Unitron Language Card

Submitted by cfkerchner on February 26, 2021 - 9:00pm

Hello All:

This is a new thread to try and figure out why ProDOS 8 Version 2.4.2, nor Version 1.0.1 (copies on disk provided to me by Thellmer of this forum), will not boot beyond the "flash screen" which shows the program name and the copyright lines at the bottom of the screen. Nor will any copy of ProDOS that I had previosly download to disk from the ASCiiExpress website using my iPAD and the cassette IN port on my Apple II+. So I know the software is not corrupted. There is something wrong with my machine.

Newbie Question about Composite on a IIgs

Submitted by big_anemone on February 26, 2021 - 12:46pm

I've been using emulators for a number of months for gaming (Wizardry, Nox Archaist) and programming (Applesoft & Assembly, just starting out).  I've gotten interested in upgrading/sidegrading to use actual hardware.  I'm a little torn between getting a IIe and a IIgs.  I'm trying to keep my expenses somewhat under control.  A IIgs by itself seems somewhat affordable, but monitor/keyboard/drives can get pricy depending on the details.

Best way to get software to IIgs in 2021?

Submitted by confusedyeti on February 24, 2021 - 9:53pm

I've just gotten my first Apple IIgs(and first Apple II in a long time, and I didn't having thing beyond floppies then), so I'm trying to map out the storage scene to get software from a modern computer(Windows/Mac/Linux) and see if there's anything missing in my research(a lot of info seems to be older, but maybe no out of date). The bare minimum of what I want to do is be able to create new disks from images, but something that emulates a hard drive.

Apple II+ Keyboard Information and Guidance

Submitted by Stargeezer on February 21, 2021 - 8:18pm

I am beginning restoration of 3 Apple II+ machines.  Surprisingly, all 3 had Videx Enhanced II keyboard add-ons installed.  You can see in the first photo the board removed (top right of photo) There is a series of pins that connect into the Apple's KB andthe ribbon cable connects into the keyboard socket on the MB.  There is a 9 pin D-sub style connector that connects to the Enhanced II's membrane key strip.
