Yes I understand that as I have been following this thread for about a year now, I'm just providing information that I think people might find useful.

I purchased the parts to upgrade the computer in my scope about 10 months ago:  AIMB-581 MB and NEC NL10276BC20-04 LCD.  I finally made an LVDS cable for the MB and did the upgrade to Win7 right after my last post here.  I used DXL's modified drivers for Win7 and had no trouble installing X-Stream 5.8.1.1 32-bit.  I don't think it really gains us much over 8.1.0.1 / 8.1.2.0, though.  I think the main additions are for features that our scopes lack the hardware to support like triggering on protocol decode.

What are you trying to reach ??? DDA was an 'option' on top of the WP... you could eventually try to wipe that one in service mode, but I'm not too sure this is sufficient ??
For the Zi series, DDA option is 01-04000000, but it might be different for the WP7K... but anyway, in service mode, you should see which key enables 'DDA'...  but again, not too sure what you expect from this...???

I only interesting. Now i have WP7300. But i see some pictures from WP7300a. So i think exists option for identity device as WP7300a and also use -XXL memory. Because -XXL only available on WP7300a.

I believe the A series also comes with a different main processor (maybe the motherboard as well, though both of these changed over the sales lifetime of the scope), and it probably comes with a different 10GHz generation and distribution board - the jitter spec is notably lower than the regular series.

I guess there's a chance it's just a better internal timebase or lower phase noise VCO, though, in which case the board could still be the same.

I want solder memory for -XXL option and need know option mask for 'A'. Other not need ))

If any have 7x00a, please let know, which options installed and if possibly memory type.

'A' is not an option mask on the WP7KA family and the memory, the MAM, is proprietary technology as far as I am aware.  This is getting off-topic for a thread about upgrading the MB...

It was bugging me for a while that this EDID block is incomplete.  The full contents up to the end and including the checksum are:

In case anyone wonders, these are the contents of the original EDID EEPROM on the AGP card in the WP7KA.
