Extra colors for hires graphics wanted ?

Submitted by UncleBernie on January 14, 2024 - 8:10pm

As we all know, the Apple II can produce four colors in the HIRES mode, plus black and white (which are not "colors", but "shades". But what can I complain. Some computer folks are so uneducated that they pervert the meaning of words all the time. Such as "clone". Back in the day, they called knockoffs of the IBM PC "clones". Big mistake ! According to "Webster's Encylopedic Unabridged Dictionary of the English Language" of 1989, a "clone" is "a group of organisms derived from a single individual by various types of asexual reproduction".

SDisk convert .dsk to .nic

Submitted by softwarejanitor on January 14, 2024 - 7:12pm

I've built a few SDisk type floppy emulators and I am ready to test them...  But I am having issues converting .dsk images to .nic images.  I can run the Java converter on Linux but I can't figure out how to open a .dsk file with it.  I've tried dragging a file into it but nothing happens.  I also tried downloading the Mac version but it is a .sit archive and the version of Stuffit Expander 16 on the Apple App Store won't open it.  And I don't have Windows and even if I did, it says the binary is intended for XP...  so not sure it will even work.  I guess I can try running it on Wine.  If t

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.

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

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.
