Hi everyone! =)
My 8280 came with a broken floppy drive and I think I'll replace it by ordering one from:
http://www.bas-ditta.info/verkoopenlinks/onderdelen%20negels...

Since I have to place an order, though, I was thinking about taking this chance and upgrade my machine as well.
What do you guys think is worth upgrading? MSX2+ or RAM or what?
And which parts would I need? I don't know what the memory-counter is for, for example; would I need it if adding some RAM?
And, last but not least, how hard-to-install are these parts?

Thanks in advance! =)

The memory upgrade requires a steady hand and offcourse the dram chips. You can find the exact instructions on the site of bas as well. The documentation is in Dutch I think but translation is no problem if you need it.

The memory counter displays the real amount of RAM in your computer instead of the hard coded 128kB of (V)RAM at the bootscreen...

Took a quick look and, while I obviously didn't understand a single word =), the pictures were more than enough to show me that it must be some kind of soldering and rewiring hell. =(
What I didn't notice at first, though, is that the guy apparently doesn't sell 'loose' RAM chips. =(

So that's not exactly essential, but cool anyway. =D

That's just what I assumed since there are no prices for the RAM modules under the 'loose' colu... wait, aren't you THAT guy? =D

Thank you very much, there seems to be a lot of interesting stuff on that page.
It's a pity that:
a) I can't read French, lol!
b) it really looks complicated, I should look for someone who's good at soldering and rewiring.

But, once again, thank you! =)

Now that I think of it... would it make sense to apply just the MSX2+ upgrade and buy a MegaFlashROM SCC+ SD with 512Kb instead of upgrading the onboard RAM?
