Video-7 RGB *without* 64k?

Submitted by TimCross on June 11, 2023 - 12:52am

Does documentation exist for this card?  I believe it is RGB (it has a 15 connector)  but just not the RAM.  Anyone aware of this card?

Apple //c repair video

Submitted by tony359 on June 10, 2023 - 4:30pm

Hi all,

 

I've recently purchased an apple //c for myself and I was told it had an issue with the floppy. Well, it turned out it was a bit more than that. I made a repair video, any feedback always welcome!

Apple III Fortran

Submitted by old_hitech on June 9, 2023 - 2:00pm

Was Apple III Fortran a real product? I read references to it from Apple from a couple of brochures/magazine articles, but do not see it listed on any price list. I recently viewed a YouTube video on the Apple III and the author showed a program selector screen with Apple III Fortran as a option to select. Is Apple III Fortran available to download somewhere?

Fastchip conflict with mouse card.

Submitted by mm09 on June 9, 2023 - 7:30am

I have a Platinum IIe with mouse card and AE RAMWORKS 1MB. I run the Airheart demo with the Fastchip (RAMWORKS OFF). After several minutes, regardless of speed, the system freezes. Without mouse card and/or with internal 448KB RAMWORKS ON, the demo runs continuously.

Alternate solution to digital copies of manuals

Submitted by Stargeezer on June 2, 2023 - 12:14pm

Hi all:

Like my computers, I am old school and like to hold paper versions of manuals and documents.  But, as we all experience, the cost of adding to our vintage collections keeps rising and rising (like the cost of everything else).

I have started printing a lot of the digital versions of various manuals and books, but many are WAY more pages than is cost effective to print at home on an ink jet.  I also hate stapled documents if its a reference book or I'm adding it to a collection of books.

Flyback Transformers for CRTs

Submitted by Stargeezer on May 31, 2023 - 9:18pm

Hi all:

Does anyone know of a good source, outside the standard eBay, to find flyback transformers for old CRTs?  I need to replace one in an Amdek 300A.

Thanks,

Mark

Weird 80 Column Switching Behaviour

Submitted by Silicon-Surfer on May 28, 2023 - 7:43pm

I'm hoping someone can help me with the weird behaviour of the below clone 80 Column card on my Apple II+. This card has onboard switching, and a pass through for the composite output of the Apple II motherboard. But when I enter the command PR#3, the cursor disappears, but the output doesn't switch.

cc65 users: printtok.c updated!

Submitted by Harry Potter on May 27, 2023 - 6:20pm

Hi!  I just updated my printtok.c cc65 C module online.  It is now much smaller in object size and adds an option to use zeropage to store two of its variables.  I also bettered its extended memory support but still didn't test this support.  :(   The compression techniques didn't change, though.  You can find it at c65 additions - Manage /ui at SourceForge.net.  Try it out!

Apple II+ Vertical Lines

Submitted by GraveFurball on May 26, 2023 - 5:38pm

Hello all,

I recently inherited an Apple II+ (RFI rev), and it seems to boot fine, but it has some serious vertical lines on the video output. I've been troubleshooting to the best of my ability, and have had no luck whatsoever getting it to work.
