Matrix patch boards (ETI 4600/Maplin 5600)

[Matthew S. Padden]

Hi..

	Somebody was askling about the matrix panels used in these two machines 
(and maybe others). The company that does them is called OXLEY DEVELOPMENTS, 
based in Cumbria, UK (I think). They do a very extensive range of panels 
from 10x10 upwards, with various numbers of layers and pin types (resistors, 
diodes etc in the patch pin itself).

They did the patch system used for the TV networks at the Montreal Olympics 
in '76. Absolutely massive patch system; it still works, apparently.

Be warned; these panels are EXPENSIVE. A simple 2 layer 10x10 panel costs 
nearly 100ukp. Bigger panels (such as the 30x30 used in the Maplin 5600) are 
around 300-400ukp, last time I checked, which was about a year ago.

They do look good though...;)

Hope this helps
