ti99iuc Posted September 9, 2011 Share Posted September 9, 2011 (edited) Hi ! i have a strange problem, and i do not know how to solve, can you help me to understand ? i have my PEB that some program read ok and some other let me know the message Error I/O 50 i have read on Disk Memory System Manual that this error is for OLD command (5) and (0) is for "Disk Drive Specified could not be found". the strange thing is that if i load another file on the same disk this one will load ok... Not all disks have this problem but i am sure that is not a diskette problem becouse i have backup of some disk and i have the same problems on backup too... i downloaded the same disk from ebay and writed with another TI99 and i have the same problem when i reading with this one PEB. so i changed the drive, the Disk controller, the 32Kb, Flex Cable interface, the flat cable for drive and no change, i have always this problem so i changed the PEB also and i have always this problem... i can catalog the disk good but i have this problem in loading... what you think can be happended ? Thankyou. Edited September 9, 2011 by ti99userclub Quote Link to comment Share on other sites More sharing options...
matthew180 Posted September 9, 2011 Share Posted September 9, 2011 It looks like you have changed everything except the console. What happens if you use a different console with the same PEB and floppy disk? 1 Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted September 9, 2011 Share Posted September 9, 2011 IIRC, IO50 in this instance usually occurs in XB and means means you are trying to load a program image file that is not for XB. It is possible the program must be loaded with Editor Assembler option #5 Quote Link to comment Share on other sites More sharing options...

It is possible the program must be loaded with Editor Assembler option #5 perfect---- in fact if i load another program will be load ok... well i tried to load in EA5 or EA3, it try to load but stopped with Error 7 however probably the program is in EA... but why not load ?

Some programs are written with a special loader even though they are EA5, they only work with that loader. My own WindyXB lower 8K product saved in EA5 format, but would only load what is saved and nothing else. You may have something like that here, use a sector editor on it like Diskassembler to see.
