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

Submitted by jrubin on November 24, 2014 - 10:50pm

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?

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"

Submitted by mbaran on November 16, 2014 - 8:48pm

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

Submitted by torindkflt on November 15, 2014 - 4:52pm

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

Submitted by Byrdog on November 13, 2014 - 5:29pm

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?

A2PI/GSport/FUSE

Submitted by Mr.Fix on November 12, 2014 - 5:45am

Hello,

I have recently started playing around with the RPI connected to the A2Pi card, with the installed Rasapple II software (great hardware/Software combination).

Being a new user to Linux and its commands I have some questions:

1. From reading and seeing on youtube, i can mount my physical drives from the A2 (cffa3000 (slot2), Scsi HD (slot7), by installing FUSE and using A2MOUNT. Is this preinstalled on A2PI? If not, how do i install FUSE (steps would be appreciated)?

What do you make of this motherboard...

Submitted by jsa on November 11, 2014 - 1:44am

Based on the registry project (Link: here ), doesn't that indicate that this board is not a II+ but a II, and not that low a serial?
