Vintage Computer Maintenance Update

• Booted up Amiga 500 that came with the two Amiga 590 hard drives.

Amiga 500

• Tried to boot up a Amiga 500 that I acquired via eBay (no power supply).
• Did not boot up — but the caps key light was powered up.  
• Next step: is to reset the chips.

Amiga 590 

• I have two Amiga 590 hard drives. Both the drives came with the wrong power supplies (the male/female was wrong).  I received another shipment that came with two Commodore power supplies that appear for the 1541 drives that seemed to work – but ran hot. 
• One hard drive was able to boot up. The other failed.
• Next Step: Get a A590 diskette and reformat the drive that works. 

Amiga 2500

• Displayed a missing disk imgae on the screen when booted up.
• Next Step: Get A2500 booted and then insert the Mac and PC emulation cards that I have.

• Did power up – not image on video.

Amiga 3000 Tower

• Did power up – not image on video.
• Missing key to unlock case.

NeXT Cube

UniSys/Burroughs ICON

• Two hard drives – both unconnected.

HP 712/60

• Recovered Root password by:  Source: http://www.nextcomputers.org/forums/viewtopic.php?t=2650
• Black hardware: 
  • Reboot the system. 
  • Immdeiately after the “Testing System” message is replaced with “Loading from disk”, hold down the right command key and press the tilde (~) on the numeric keypad. You are now at the ROM monitor. 
    Boot the machine into single user mode. Most people boot off the hard disk, and should type the following at the ROM monitor prompt: 
    • bsd -s
  • Once the system has started and dumps you at a root prompt, you need to make sure NetInfo and other services get started. Do this by typing: 
    • sh /etc/rc &
  • Set the root password using: 
    • passwd root
  • Now, reboot the system and you can use the new password. 
• Intel hardware: 
  • Reboot the system.

IBM 7690 Clinical Workstation

• Request from another collector to find the user manuals and any software I had with the system.  
• Located two manuals – Technical Reference and Guide to Operations.
• Located one diskette: IBM 7690 Clinical Workstation Customer – Level Diagnostic Diskette
• Will make an archive of the disk and scan in the manuals as a PDF.
