I'm at restaurating a CMI III that i managed to aquire but have a strange problem, that i hope the whole knowledge of this combined group can help me getting this wonderful instrument back to life..
What is at hand:
I have the following cards:
WFM-32 Slot 2
CMI31 Rev 2A3 x 8 Slots 8-15
CMI32 Rev 2 Slot 16
CMI41 Rev 1 Slot 17 (with new EPROM and jumper LK5 on 1&2)
CMI28 Rev 4 Slot 18
Q356 Rev 2A Slot 21
Q133 R6 Slot 23 (with new EPROMS)
Q209 R6 Slot 24
Q219 R3 Slot 25
QFC9 Rev 7 Slot 26
Q777 Rev 2 (empty EPROM Socket) Slot 27
After Startup the parity error led on the q356 goes off after 1 sec, so the main CPU's seems to boot from Q133
4 led on for a Second on CMI 41, 2 led steadily on cmi28 and the lowest led active steadily on cmi31 in Slot 9 & 11..
All Other LEDs are off..
And all i get is the text 'BOOT ROM V17'.. with the rotating cursor.. as per the attached image..
pressing SPACE (that should show the Diagnostics Page) brings the cursor to a one second stop.. but then again rotates.. and nothing more happens..
Does have anyone have any idea what is wrong? What i can test? How to debug that further?
Thank you very much for any suggestions!!
best regards
Daniel
