This small PCB replaces the two 6550 RAM chips which provide video RAM in the original PET 2001 series computers. The 6550s run hot, are unreliable and are becoming unobtainium so this replacement allows your precious 6550s to be preserved with no lost of functionality.
Whilst repairing my PET 2001-8, PETunia, I was looking for a solution that allowed me to run the computer at lower currents and less heat dissipation. In particular the 6550 RAM (and the 6450 ROM) runs toasty due to the 1979 MOS technology, by using a modern replacement the system runs cooler and consumes less power.
The PCB is designed with modern components and uses edge pins to minimise its footprint, in fact it fits entirely within the space previously occupied by the two 6550s. The nice green colour blends in with the original PCB to give an aesthetic pleasing solution to all your Video RAM needs. The Batten and Allen edge pins work nicely with the existing sockets.
