I am looking for RDOS Disk Test Error code listing.
The other thread about the FDC for the Cromemco got me thinking it was time to try my System One again, I had not been able to get it to output to a terminal, but I had not tried since 2008, according to my notes.
Long story short, now I can boot my Cromemco System One to RDOS 2.52, using a 16FDC.
Taking it further....A thought-to-be working system diskette does not boot in this system on either drive. I suspect two bad disk drives, but I can't prove it yet. But at least I have a RDOS prompt finally.
Sometimes the message "stand by" comes up and the system hangs
Sometimes it makes it to this error:
Unable to boot
0001-0
Err-B 34
RDOS 2.52 has a test program that is activated with the command "T"
1) The memory test returns an "X" on the C page.
0 1 2 3 4 5 6 7 8 9 A B C D E F
^ ^ ^ ^ ^ ^ ^ ^ ^ ^ x ^ ^ ^
The manual says an "X" is bad, but isn't this where RDOS is located? I can see the code is there, so I am not sure how to interpret the X vs. the ^. I have two 64K Cromemco memory cards, same results.
2) The test program continues and when I run a disk test on either A or B drive I get an error as follows, so I am looking for the error code list so I can troubleshoot the meaning of the error:
Seek tests:
01:error 30
Fortunately these systems came with Tandon drives so I can try another drive, after testing in an IBM PC to be sure it works OK first. I guess this system has two bad drives?
If I replace the drives and the system works, then I will let you know.
