BBC B Econet Interface
Issue 4
A quick glance at the issue 4 board and we can see that Acorn have introduced widespread changes to the Econet circuitry. Firstly, the layout is different. The resistors are now mounted flat on the motherboard. ICs 90 and 92 have disappeared along with links S3, S5 and S6. The clock generator has gone, as has the terminator function.
