Hello everyone,
It's been a while, but in case anyone is interested, I'm letting go of one of my prize possession (Sony HB-F700P in very nice condition) since I mainly play cartridge games on MSX, for which I already use another machine. I put an ad on Marktplaats as well (local Dutch eBay equivalent site), but if anyone from here has serious interest send me an e-mail (should be on my profile) and I'll consider your offers as well.
NOTE: I'm also willing to trade for a complete copy of Metal Gear 2 Solid Snake. Depending on the condition I'm willing to pay extra from my side if needed. Only this game by the way! 
Info on the Sony HB-F700P:

Short recap in English:
- Little to no yellowing on plastic (mouse slightly more beige than the system)
- Has seen minimal use, little to no wear visible. Also no cracks or dents as far as I'm aware
- Both cartridge slots fully working
- Floppy drive works fine, booted with it and also copied/wrote some data without issues
- Keyboard works fine, might need some cleaning inside as a few keys (mainly around the enter key) require a bit more of a push to register
- Mouse also works
- Everything is in factory condition, so no upgrades
- Ad will remain online for a minimum of one week's time
Shipping internationally is available (I'm in Holland) but will only send this insured in case it's damaged or lost. If you're interested I can let you know what the costs would be.
Regards,
perfectnarcosis
P.S. Can share larger resolution pictures if there's interest. Marktplaats is known for compressing the original ones to a puddle of mud sometimes ;)
Took me a while to make the decision but it's not being used at all and that in the end saddens me more
