Free PCBs

Submitted by Stargeezer on January 23, 2022 - 10:19pm

Hi all:

I have some PCBs for a PS2 to Apple II/II+ interface based on this sites design https://knzl.at/ps2-keyboard-for-apple-ii/

There is a minor issue.  As these were first effort boards, the PS2 componenet mounting is backwards.  They are also untested.

The PS2 port is facing the socket locations.  It should be facing outward.  That being said, it would be easy to jumper it from the socket to a panel mount or similar.

If you would like one, drop me a PM.   I only have 3 boards available.

Hi Everyone. I am looking for the LISA assembler for the Apple II, version 2.6. I've looked on Asimov and other sites and have only been able to find version 2.5.  Thanks!

FujiNet Apple2 bring-up instructions for DIY

Submitted by Thomas Cherryhomes on January 22, 2022 - 3:29pm

In case it's not evident:

You can build an #apple2 #FujiNet using the schematics for the Fujinet 1.0, or using a DevkitC on a breadboard and wiring it up to a DB19 connector according to the instructions in:

https://github.com/FujiNetWIFI/fujinet-platformio/blob/iwm/lib/bus/iwm/iwm.cpp

using the board bring-up instructions:

https://github.com/FujiNetWIFI/fujinet-platformio/wiki/Board-bring-up-for-FujiNet-Platform.IO-code

and using the code in the IWM branch: https://github.com/FujiNetWIFI/fujinet-platformio/tree/iwm

Unitron keyboard alternatives

Submitted by Stargeezer on January 21, 2022 - 9:12pm

Evening friends,

A while back I obtained a United U-2200.  Based on feedback from several members in earlier posts, the actual Uniteon keyboards are very rare.  I know Apple II+ keyboards can be modified to work, but it pains me to tear apart an Apple II+ to scavenge it's keyboard.  

 

That being said, I am looking for alternatives and would welcome any suggestions.

 

My thought is to take a 'claky' USB keyboard and convert it to work as the Uniteon's externally connected keyboard.    I am just beginning this quest and the following comes to mind.

from 48K to >48K

Submitted by warby on January 20, 2022 - 12:56pm

Hi all,

 

I'm looking for options to increase my original Apple ii plus RAM. I have a boot ROM so I'm not necessarily interested in the language card but after posting on the wanted-to-buy forum and searching ebay, I'm not seeing any 16K expansion cards.

So... what are my options here? I do see super expander cards for sale but I'm not confident they work with an Apple ii plus and they are $50 with no RAM chips.

Any other options available?

Thanks!

Warby

Anyone know the part number for the Edge Connectors (slots) for an Apple II?

Submitted by DistantStar001 on January 18, 2022 - 10:39pm

The title pretty much sums it up.  I have an Apple ][ plus board with a damaged connector at Slot 6 (pretty important slot), and I'm looking for a replacement cheaper than what I'm seeing on eBay.

ATX to Apple II: need PCB help

Submitted by Tom Owad on January 18, 2022 - 7:39pm

I'm working on a board to add a -5v signal to an ATX power supply, so it can be used to power an Apple II. The design is based on SpeedyG's, but I wanted something I could just plug an ATX power supply into, rather than cutting it up. I've always wirewrapped or breadboarded, but I wanted to do a proper PCB, now that they're so easy and cheap.
