Hi !
Could anyone give me the REAL pin assignment of the
terminator used on the IBM 5110 / 5120 systems ?
Has anyone build such a terminator ?
I tried to build one and I'm fed up with getting always the
same error : I can obtain the file list (using basic command
UTIL DIR,D80 or UTIL DIR,D40) but 5 seconds after giving me
the file list, the systems blocks, the promt disappeared and
I must restard all... No led is lightning on the
pannel...Sometimes I get the 24 or 26 error code (''diskette
error...''is only said in my reference manual : what a help !).
Very strange diagnostic...
Thanks for your help ;-)
Fred.
I have scanned the two pages from the 5120 MIM that address the pinouts.
Hope this helps. Let me know if you have any trouble reading this - the
pages did not scan that well.
