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".

RAM Test Duration?

Submitted by MagicMarc-er on June 22, 2020 - 6:41pm

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

Submitted by dfnr2 on June 20, 2020 - 10:07am

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

Submitted by Timelord on June 18, 2020 - 12:35pm

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.
