This listing is for a working full kit based on AMI Atlas PCI-III Rev D Series 757 Motherboard that will ***fit all*** oscilloscopes branded "HP Infinium"

This applies to 54835A, 54845A, and 54846A. If you have a unit branded "Agilent Infiniium", contact me for details.

This kit is also an upgrade for 54810-66512 (Rev C), and 54810-66510 (Atlas PCI-II 727 motherboard, no USB headers)

This kit is analogous (actually superior to) upgrade kit "E2633-68701 for Serial No. Prefixes lower than US3845".

The kit covers:
  • 54810-66524 (A4: AMI Atlas PCI-III Series 757 Motherboard Rev D, the latest and the greatest of the series)
  • 1818-7682 (A4A2-3: the original one has 32MB only. I upgraded it to the max 256MB possible.)
  • 1821-4976 (A4A1: AMD K6/2-300 CPU)
  • 54810-68726 (A9: Preinstalled DOM SSD with fully working Windows 98 loaded with HP Infinium scope software intended for this motherboard)
    This DOM upgrade reduces the clutter because the module sits on the IDE port directly so there are no cables flying around.
The price of this listing includes support to make sure the kit works for your Infinium. Here are 2 options (no extra cost):
  • Have the kit sent to you and I'll support you over email to install it.
  • Recommended: send/deliver your Infinium oscilloscope to me (you pay for shipping both ways) and have me install it for you. Here what you'll get:
    Free USB 2.0 interface. I'll also upgrade your Windows 98 to take most generic USB flash drives (or external USB drives) without drivers.
    I'll take your old motherboard, CPU, hard drive and RAM.
I encourage sending your unit to me for upgrade (or motherboard swap) because HP Infinium series' computer side is nasty to deal with in general. 
It's likely to be more work for me to walk you through the quirks over email than doing it myself (since I've figured out the rough edges).

I only have one unused board available, so first come first served.

Having the unit work for you is more important the price paid.
