Sounds like the original poster might be an ideal candidate to become a new Amiga user for life. I hope he does not get too disappointed with the A2088 bridgeboard, they were crap. A 386sx bridgeboard would be much better to run old DOS apps and games on his A2000.
Anyway, welcome to Amiga.org Alfred and enjoy your A2000. If you can't find an Amiga keyboard and mouse for a good price closer to you, contact me via PMail here on Amiga.org and we can make a deal on extras of those that I have in my collection. I am in Calif., so the shipping shouldn't be too much via USPS parcel post.
