Ah, MSX-Computers, i love that system
Congrats Zozo for the NMS8280. It's a really nice system with the possibility to upgrade it to the MSX2+ standard.
Because of games: You should try some japanese shooters like Space Manbow. This game supports MSX2 and MSX2+.
The problem with MSX1 machines was the missing hardware scrolling. So games like Nemesis, Parodius and other horizontal scrolling games are not really looking good on MSX systems.
If you want to go further with the system you can connect the HxC floppy emulator. Also there is a great flash cartridge that you can get from france, the URL is

http://www.msx.orgPersonally i have one MSX1-system (National FS-4000, a japanese computer with internal thermo printer), a Philips NMS8280 and a Panasonic A1-FX MSX2+. Also a MiST-FPGA computer with an MSX-core
The MSX is a fine system, but it's nearly impossible to collect all variations of MSX-computers or MSX Software
