About the New enet PCB
New enet is an open source PCB design by jayacotton, published on GitHub under the MIT license. It is a 2-layer board measuring 254 × 134.6 mm, with 36 components from 25 distinct parts.
Other key parts include the 74LS10, 74LS688, 74LS163, 74HC02 and L7805. By type, the board carries 15 ICs, 7 diodes, 6 resistors, 4 connectors, 1 module and 1 switch.
It belongs with the retro computing designs in this gallery.
From the project
Inet tools for z80-rc2014 tcp/ip stack code.
In this section we have the BOM for the MT011 board as built for my needs.
For the best and current information about the MT011 board see https://github.com/markt4311/MT011.git
Find here the mt011-bom.ods a spread sheet for the BOM of the board. And the schematic (copied from above) MT011SPIWIZNET.pdf
I will include a picture of the board as built.
This board is now working on 18mhz cpu rc2014 systems.
