Apple IIc Disk Drive - External into internal? (Yes!)

Just a quick question...does the external Disk IIc drive have the same "guts" as the internal drive in the Apple IIc? I.E., would it be possible to remove the Disk IIc mechanism from its external case and then use it to replace the internal drive in a IIc system? I ask because my IIc has an ailing internal drive (I presume it's some sort of mechanical alignment issue, it only reads when the system is physically flipped upside-down and even then only sporadically), and it's appearing much easier to find external IIc drives on eBay than internal ones.

Thank you.

Bad memory in the extended memory of the 80 column RGB card

I used the sequence which tested the memory, and returned the following over several iterations

*RAM ZP 0 0 0 0 0 0 0 1
*RAM ZP 0 0 0 1 0 0 0 0
*RAM ZP 0 1 0 0 0 0 0 0

Does anyone have a source for replacement ram chips?

Resurecting early Apple II - Getting Started Guide / Recommendations requested

Now that I have retired I am planning to play around with my original release Apple II (Serial A2S1-0734).
It had some basic upgrades.. programmers aid, language card, dual disk drives, Silent Type printer, 80 column card, etc. - Original chips and jumpers are still around if needed.
Looking for some recommendations/insights/advice on the best way to proceed.

Apple //c video "interference"

In the linked you can see a rolling "interference" through the display.

This only occurs when the //c is on, but not while just the Monitor //c is on.

It does appear to be more shaky and will distort the text characters on floppy read/write.

Is there a filter/capacitor/component that is responsible for this type of effect that I could replace?

FIXED! - Apple II Plus Bad Memory/ROM? - The saga continues

A few years ago, I won an Apple II Plus off of eBay that turned out to have a fault of some sort. After as much troubleshooting as my limited technical knowledge would allow, the problem persisted. I sought assistance on these boards, and after much back-and-forth over things to try and check...no luck. Eventually, an ugly thing known as life forced me to shelve the project.

Albert Computer

Hello Fritter forum,

Long time stalker first time poster here.

I am posting in hopes of gathering some information regarding the Albert computer.
I know it was marketed as a “Smarter Then Apple” computer. I have also read the write up on resestvector.com as well a brochure or two on it.

What I’m trying to determine is how rare they are or how many were made? It appears that the company was only in business for 12-18 months and failed to gain much traction before apple shut them down?

Does anyone have any memories of using them or know anyone who did?
