Submitted by PraetorX on July 2, 2020 - 10:53pm

I'm looking for a book I used to own called Exploring Apple GS/OS and ProDOS 8 by Gary Little, but can't seem to find a PDF.  Can anyone point me in the right direction?

"Mike's Magic Matrix" bitmap shape editor?

Submitted by PraetorX on July 2, 2020 - 3:31pm

In a couple issues of Apple Assembly Lines from 1982, I found references to a "Mike's Magic Matrix" tool that was under development by Mike Laumer, frequent contributor to the newsletter and author of the FLASH! Integer BASIC compiler.  It sounded like Mike's Magic Matrix was a bitmap shape/sprite editor tool.  Development soundedto be pretty far along, as the author indicated they he had only a little more adjusting to do and a manual to write, but aside from these references in Apple Assembly Lines, I haven't been able to find anything more on it.  Anyone have any information?

Feast of Apple IIe mainboardyjfy

 

Fortunately, I got a piece of Super II, collected some related materials, and dedicated to friends who are interested in Apple IIE.

 

In 1980,Apple IIE's first design project called "Diana". Diana was intended primarily to be an Apple II that had fewer internal components, and would be less expensive to build. The project was later known as "LCA", which stood for "Low Cost Apple". the final code name for the updated Apple II was "Super II", and lasted until its release.

Generic 5.25" disk drives

Submitted by css on June 29, 2020 - 10:01pm

Awhile back I picked up this pair of non-working generic 5.25" disk drives in a lot of Apple II equipment. I don't know much about them but was wondering if any of you have worked on similar units?

My other drives are Disk ][s.   I've cleaned the heads on these but they still won't read any disks. Not sure how much effort is worth diagnosing these and I assume there's 

nothing special about them?

Tapping into the motherboard to get better video in a PAL IIe

Submitted by CheshireNoir on June 25, 2020 - 2:51am

Hey Folks,

I've been doing some looking around to see if I can find an answer to this question: Is there somewhere upstream of the Composite socket you can tap into to get a "better" video signal, and by that I mean a signal in a less combined format.

(I suspect the answer is "no", but I'm just not that good at following schematics)

Apple Graphics Tablet STYLUS

Submitted by macnoyd on June 24, 2020 - 1:26pm

Does anyone in AppleFritter land have any info, schematic, photos, etc. of the old Apple Graphics Tablet Interface Card  STYLUS?

I'm looking specifically for information pertaining to the Stylus itself.  I have the Tablet and interface card but am missing the Stylus for it.

I know it has a coil (inside the pen) and possible other circuitry, but I don't have any details for it.

Cleaning Joystick Pots

Submitted by nick3092 on June 22, 2020 - 10:23pm

I picked up an Apple 2 joystick that was having issues.  One of the buttons didn't work, I was able to remedy that by putting in new switches.  However, the pots also need to be cleaned/inspected.  I prefer to do that by actually opening up the pots and cleaning the contacts and track, vs. blasting the entire thing with a can of contact cleaner.  As contact cleaner also clears out any grease in there, and makes the pots feel too "loose".
