The Amstrad CPC range of computers can have the distributor name changed by connecting links on the motherboard. The links are LK1,LK2,LK3. These links are connected to PPI Port B, Bit1-3. The links select the distributor name which is displayed when the CPC starts up..
These LKs exist on all CPC mainboards. By default, LK1-LK3 are not installed (Amstrad). Other combinations are LK2 installed in german Schneider models, and LK1+LK2 in australian Awa models.
Well the other 2 are very strange I never lisen those names.
