I also want to upgrade the memory of my HB-F700P, preferably internal... So If you have any more info, please let me know as well.
Many thanks !

I got this schematic from Jipe. It should work for the HB-F700, but I haven't made it jet, so I can't tell for sure...
Sony HB-F700 schematic for 1Mo memory mapper

I'm going to make an external one that also was not tested for the Sony, but I'd rather experiment with an external memory mapper, than having to solder inside my HB-F700.
Eighter way, I hope you can use the schematic, and I'll let you know if my project was sucesfull or not.

When I bought my 700 from Repairbas, I asked him to put in some more RAM. Unfortunatly he said the required parts were no longer available... Forgot which parts they are... I doubt RAM chips Wink
As I am a soldering disaster waiting to happen, I think I settle with the standard 256KB...

I'm pretty good at soldering (used to repair laptop mainboards), so I'll give it a try anyway. If I succeed at building an external one, I'll let you know...

Wondering if someone ever tried to get colour composite signal out of the HB-F700 instead of black&white ?

Want to hook my HB-F700 on an USB Capture device on my pc.
But the price of a RGB to composite converter is far beyond my budget Eek!
RGB gives a very clear and sharp image on my 32 inch TV Cool but that one is not standing on my desk so i want use the Capture device as cheap "monitor" and also record some video/audio if desired.

Shaiwa,
I also wanted my HB-F700 on a flatscreen monitor on my desk, next to my PC monitor.
The cheapest way is to find a flatscreen monitor with scart input on marktplaats or ebay (i found 1 for 15 euro's, works perfect)
Older monitors with scart and vga input most of the time support the RGB scart.
RGB signal is the way to go, recording you can always do on an emulator.
