IBM or compatible PCs What can i say about the RM Nimbus... it was one first PC I remember. i used one at school and had one at home, too. It looked like a huge brick and its 25mhz could be boosted to a massive 50mhz. I used to play games such as Cartooners and LSLARRY. Oh, and I can't forget the first Wolfenstein on it. Wicked machine!
