Greetings! Please forgive the operational questions (we still are manual-less) but if we can get the box to boot the quest for support materials for our IBM 5363 III will be clearer. We've solved the case-entry problem and a PC running 5250 emul. is now recognised as the console. Rewiring the keyswitch allowed selection of Maint. mode. At IPL the console displays a countdown banner from 4 to 1 accompanied by cursor shifts and beeps; the SSP load commences and stops with a frontpanel display of '0010' and cursor shifts and beeps on the console. The 'program' led is lit. Selecting func. 5, sys reset, and then func. 9 'start ssp' invokes a dump utility on the console. We've tried DD and HD diskettes formatted in a variety of ways for the dump but all are rejected. This sequence is repeated at each IPL. Can someone describe both the meaning of the '0010' error and what a normal IPL should look like? What support diskettes were provided (microcode, maintenance, etc.)? What is the low level and high level format of compatible diskettes (are some formats PC-floppy readable to create disk images)? What is the likelihood of obtaining (at least hardware and operation) manuals from IBM in paper or microform and would contacting Rochester (MN) be the most effective approach? Thanks to the list members for all help. Michael Grigoni Cybertheque Museum
