Apple IIGS - RESET line stack on 0V

Submitted by jabuka2 on January 12, 2024 - 9:07am

Hello,

Weird problem here:I bought an Apple IIGS (in non-working condition), ROM01. The motherboard is in bad shape, the battery has leaked everywhere and damaged the traces.

The previous owner fixed the wiring and replaced some ICs.

As far as I can tell the repaired tracks are OK, I've checked them all.

A2VGA Boards

Submitted by Stargeezer on January 8, 2024 - 9:26pm

Evening all:

I am considering building an A2VGA board outlined in skate323k137's the blog entry.

Five boards from PCBWay look like they will run me about $33.  Is anyone interested in splitting the cost?

I won't need 5 boards and thought this might be an option to save me and up to 4 friends a few bucks in fabrication costs.

PS/2 keyboard adapter for Platinum //e

Submitted by softwarejanitor on January 6, 2024 - 5:33pm

Does anyone know if the Option 8 RetroConnector Keyboard Interface //e like this:

 

https://www.tindie.com/products/option8/retroconnector-keyboard-interface-for-apple-iie/#specs

 

works with a Platibum //e?  I have a Platinum //e with a keyboard that is basically unsalvageable.  I have the motherboard, case, power supply...

 

Not sure if I would need to swap out the keyboard encoder ROM to an original style //e one to make this work.

videx softswitch not working

Submitted by dragos on January 5, 2024 - 4:46pm

I have a II+ with a Videx and softswitch, but I cannot get the 40 column output on the videx output.  I have triple checked the installation and it all looks correct according to the manual.  When I activate the Videx, I get the 80 column output no problem?  Any ideas?

 

Thanks!

A2USB: Apple II Mouse Interface Card & USB Support

Submitted by MacFly on January 1, 2024 - 10:50am

I wrote a blog article on a new firmware project: A2USB. Adds USB support to the well-known A2VGA boards and emulates an Apple II Mouse Interface Card - connecting a standard USB mouse.

Currently requires a bit of tinkering - as described in the blog. Already works really well, but still needs testing on more and other machines.

Creating this forum topic for possible discussions - in case someone wanted to give this a try...

Questions abou my new apple II

Submitted by StefanUlm on December 31, 2023 - 12:10pm

Hi everybody,

 

in my youth the Apple II was the unreachable dream. I had to settle with a ZX 81. Now i bought all the machines of my youth again (ZX81, Dragon 32, Amiga 500) and finally also got myself an Apple II europlus. It has a lot of expansion cards. For some of them I have questions that I could find no answers online.

Lower case on the Apple II+ WITHOUT the shift mod?

Submitted by Screwtape on December 30, 2023 - 2:24am

I went back home for Christmas, and my father had retrieved my boyhood Apple II+ from storage. We originally got it second-hand, and it came with some expansion cards and some mods installed, but I was a child, so whatever the computer did was what I assumed it was supposed to do. Now I'm older and a little nostalgic, I've spent some time reading up about the Apple II+ hardware, watched some videos about how things were supposed to work, and grown curious about how my Apple II+ had been configured.

Skipping ahead to the observations:
