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

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

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

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".

RAM Test Duration?

I have an Apple IIc with a (not) 255 ROM version since peek(64447) yielded "64" so I ran the RAM test and, it started by giving me the appropriate psychadelic screen and the slow metronome ticking sound through the speaker at about 45 beats per minute.  I used an online metronome to time it out.  Here are my questions:

Cherry MX key preference

I'm looking into the possibility of building up some ASCII keyboards for those who prefer not to build their own. The options for keys are Futaba MD-series keys and the various Cherry MX options.For those of you who have tried out different Cherry MX keys, I'm interested to hear your key switch preference for an Apple I/II keyboard.I while ago I got a sampler keypad with the various Cherry MX types, and I thought that the Cherry MX Red was a good feel, and closest to what I expect for the era.

UtherNet / NIC Cards and Software

I'd like to hear some experiences, and suggestions, regarding Ethernet NIC cards, including the Uthernet; as well as what software can make use of them; e.g. for IRC or for Lynx. 

 

Further, if there are other GS/OS chat or Internet must-have utilities that would work with them; and what slots they tend to use.

Apple //c high memory app crashes?

I recently just got my very first Apple II, a //c ROM version 255 hooked up to a floppy emu. The computer turns on, seems to boot fine, AppleSoft works etc. I can run some programs fine like Oregon Trail but others either crash straight away like every version of Merlin, crash a bit later like Apple II desktop or a2osX or have strange symptoms. Sometimes it's just one or two characters being replaced by the delete character other times it's weird issues like all visible text in AppleWorks just vanishing.

Fried IIGS ADB Port

So... My IIGS was working just fine and I plugged a ADB cable I'd never used before into it and became distracted momentarily by something else. I soon, however, noticed a bad smell, and reached down to find that the ADB cable I'd plugged in was quite warm, almost hot to the touch. I shut the IIGS off and unplugged the new cable, and I tried one that I knew worked (and had just tested with my Performa 6200CD), but to my significant dismay, the ADB port no longer responded.
