Apple //c Plus Hardware Test

[UNA_Lion]

Okay, conducted a hardware test IAW the following instructions:

1. Simultaneously press the CONTROL and RESET keys during boot.
2. Enter CALL -151 and press RETURN.

The machine language monitor prompt (*) will appear.

3. Enter C40AG(the numbers here are four and zero, not the letter O) and press RETURN.

... and got the following:

CARD SIZE = 1 MEG

PASSES = 0000

CARD FAILED

ADDRESS ERROR

SEE DEALER FOR SERVICE

0101- M=00 A=04 X=C1 Y=A0 P=F0 S=DE

Opened my machine a few days ago to check on some tiny piece rattling around in there, and don't recall seeing a memory expansion card plugged in, so any idea what the above message might mean?

ps - Somehow, think seeing a dealer for service isn't a viable option

The Memory Expansion Card test on an Apple IIc will give. results whether or not a card is actually installed.

. When you run the diagnostics and there is no card you

. should see=

. MEMORY CARD TEST ESC TO EXIT TEST WILL TAKE 180 SECONDS

. CARD SIZE = 1 MEG

. PASSES = 0000

. CARD FAILED ADDRESS ERROR SEE DEALER FOR SERVICE

. 8002- M=00 A=04 X=C1 Y=A0 P=B0 S=CE

. (M is the memory bank where failure occurred)

. If this is the message you are getting then you may not

. have a RAM card (or it may not have RAM in it).

Thanks for the answer and the link.

Still trying to find a scanned Apple //c Plus owners manual online, so I can answer these questions myself.

The helpful folks at Applefritter posted this, but I can't get it to open.

It will work better if you right click the link and download the file, but it will take about 4 hours or so to download. Not sure why it's running so slow from there, I've downloaded things before at better speeds. You can download it just be patient.

It did finally download: Went to church, and by the time I got back it was downloaded.
