Hi all MSX'ers!
I recently got a Philips NMS-8255. My first MSX2 machine! =)
It works well, but, I've noticed that the picture brightness level, and PSG sound level varies annoyingly at times (strangely SCC sound level stays same all the time, though I only tested a few times). It's a bit difficult to describe, but the general brightness of the picture gradually (and slowly) gets higher, as does the sound level, then (maybe after 1-4 minutes) there is a sudden drop in the level (and sometimes a mild *pop* from the speakers). While I was playing boulder dash, when this drop occured, the MSX hanged =(. Luckily after a while it was alive again.
At first, I thought that it is a faulty SCART lead, but the hang made me think otherwise... also I checked the lead and it does not seem to be the case... anyone had a similar problem?
I also opened the MSX to see what it looks like inside =). Also to see if there are some clearly broken elcos or something, causing the above problem. I noticed there is a jumper (soldered wire) for 220V and 230V... I believe it was at 220V setting, could this be the cause of the problem above? I didn't look so carefully because I remembered we have 220V here in Finland, seems I was wrong ;-)
Also, I'm thinking about modding the MSX cradually... at first I'm thinking about adding RAM, then VDP9958 and later MSX2+ BIOSes... But I can't find 41464 (or 4464) type memory chips anywhere (these were used in the expansion instructions I could find, and are also the type already on the motherboard). Does anyone know where to order some? I might be able to find some 1MB 30-pin simms, though, perhaps I should use those ;-)
Also, if someone can point me to a place were to get the VDP9958 and MSX2+ BIOSes at a reasonable price, that would be appreciated :-)
Cheers!
- Ville
