Data General Eclipse

You are right about the cpu expansion to a 9300. The machine does not NEED 240vac to operate. Nearly all MV's were 120volt except for the very very largest ones. Your's has a set of jumper wires in the back of the power supply which 'tells' the ps which current to use. Internally the power pack will split the 240 into 120volt so be careful and ask before you power it up. I'd hate to see the supply smoke before you got a chance to play with the machine. The Eclipse is OCTAL which takes some getting used to.... You are very lucky to get the machine. The other two fellows in the group who have MV2000dc and MV5000dc machines have thier work cut out for them. Your machine is a 'standard' eclipse and so can share parts with most other MV's. You can also read/write the standard 9track tapes which is very fortunate! Just let me know and I will be glad to run off a set of install tapes for networking and AOS/VS II. The machine is OCTAL! This is really important because the device codes for boot are octal. usually the machine will boot from device code (octal) 22 or 24 which usually references the first 9track tape unit. It will boot from hard disk once you have the OS set up. You need microcode to get anywhere. I should have the code in my collection. Getting it on the machine is another story entirely. Verifying the machine is pretty easy. You boot a diagnostic operating system called Adex or Ades - they changed the name when AIDS became a medical issue.... I have several versions. The adex/ades tape contains microcode for your machine as well as lots of utilities and diagnostics. I can also run a copy of ADEX for you. If you can provide the tape media for the copies it would be a big help. I would need three 7" reels such as the Scotch 700 or blackwatch 700 from 3m, and one 'short' tape. (Two 700's for aos/vs II, one 700' for TCP/IP, and the shortie for Adex.) If you don't have media, I'd guess about $20.00 should be enough for tapes 'short' tapes but no 700's to spare. Because your's is a normal MV, I have several spare cards for it; a working 2mb ram card, a non-working but fixable 8mb ram card, and a working 16line serial terminal controller card (IAC16) - not that you need any more terminal lines ;-) I also have a spare, working tape controller for a 9track drive. Does your 9track have the reels side-by-side or over/under? There is a difference between the capacities of the two types though tapes can be interchanged to a degree.
