I'd like to know if it's possible to upgrade / mod my Philips VG-8230 MSX2 to a 2+?

I have no electrical knowledge, but I can use a soldering iron and desolder station pretty well. I'd just need to know what the BOM is, and what needs to be down to the motherboard.

I've read in the past that it was possible to upgrade later versions of the Philips machine.

Don't you think that having a rare 8230 and modding it is a wrong idea? I'd not touch it Smile I'd buy a 8235 and mod it (and there are more info on exactly those machines, so it would be easier)

VG-8230, the very first MSX2 from Philips Smile I'm not sure it's very rare though, quite many were shipped for industrial purposes in the Netherlands. E.g. the NIPO had 1000 (I have such a 8230 box with a NIPO sticker on it).
It also seems quite some pharmacies had them.

Oh well i was sure it is more rare that it seems to be Smile
But for modding purposes there are people who modded 8235 while 8230 might have some investigation and extra efforts btw, so this is less convenient to mod 8230

If it is a matter close to your heart to upgrade an 8230, there is certainly a way that will keep you busy and give you new knowledge.
Otherwise, buy a 2+ or enjoy your MSX2 as it is.

Does your machine have the original 64kB of main RAM?

The problem to upgrade the VG-8230 to MSX2+, it is that there is no memory mapper. This complicates the upgrade a lot.

Not if you use the RAM expansion that can be installed into the Z80 socket.

I don't really care or not if it's rare. It'll be mine until I die, or it dies, whichever comes first. It's not like mine will be the last on the planet. Smile Also, buying yet another computer right now, really isn't really within my budget. MSX2+ go for quite a bit of money these days it seems. As for upgrading (if possible) would be way cheaper from what I've seen other machines upgraded for.

As for the ram, being the original, how would one know?

Run a RAM tester. If it reports 64kB RAM, it's the original.
