I wake up this thread with respect to USB on the scope.

According the experience of ntcnico, it seems that removing the floppy create some problem, it is a pity because usb floppy slim emulator are available and they are cheap.  :wtf:

Other solution since I think there is one PCI slot free on the motherboard is installing a PCI USB adapter with support for Win98, they are available on ebay second hand for a few €.

I just checked the rise time from my Infiniium scope, 232ps, this confirm the 1.5GHz bandwidth.  :-+

Update on my scope:
USB: My motherboard support 2 USB connections on the motherboard.

I bought this unit: http://electromyne.de/Server-Parts-Supermicro-FPUSB813-Server-Front-Panel-2x-USB-Serial-COM-RS232-Silver-Silber.html
Fit perfectly in the place of the original floppy, com port as well on the front.
It is plug & play and no need to pray, cables, screws all fit perfectly, com2 is now connected to the front panel.  :-DD

Manage in the bios to disable the floppy and work without problem with the floppy removed.  :clap:

I added as well memory, very cheap from the same shop and was shipped in 2 days door to door from Germany.  :-+

Got the exact colour to repair the little scratches and blemish, now my scope is in a real mint condition.

Install a pdf printer emulator.  :popcorn:

Now hunting for probes.  |O

What was the real impact of adding the memory? Was it just faster operation due to less swap file access or did it make the actual scope memory depth better?

I think that you should paint the USB/COM port the same color as the front panel since you have the paint.

EDIT: PS, nice job though!  :-+

On the Infiniium software I don't see any improvement, when using Win98 explorer or other programs it is more reactiv.
