On the left side of the Pegasus motherboard you can see a small blob of putty. This putty is hiding a series of diodes that act as a simplistic 8-bit ID. This 8-bit ID will only allow EPROMs encoded with a corresponding ID to work in any individual machine. For example, an EPROM from a machine numbered 2569 will not work in another Pegasus with a different ID.
It feels like an 8-bit ID shouldn't allow a machine numbered 2569. Can anyone expand on the ID? — 184.108.40.206 (talk) 14:26, 11 January 2012 (UTC)
