Updates from v1.0
- The silkscreen says 4K7 for the resistors, but with the WINBOND they can all be changed to 10K (as in this picture).
- The DIP switches from left to right are, A13, A14, A15 - but should really be the other way around, to match the binary pattern and bank number in EEPROM.
- Support for 16kb ROM, needed to run SPonZY (ZX Spectrum ROM modified to run on ZX81 Hardware).
- Rotate the ICs 180 degree, just to make the text in the right direction (I know - it's not important, but...)
- Added JCLJCLJCLJCL to silkscreen, to specify "JCL order no"
- Making PADS 2mm longer, to prevent potential issues with some connectors (when used in the Expander board)
- Changed from pull-ups to pull-downs, to match actual behaviour of DIP-SWITCH (up = 1/ON/HIGH, down = 0/OFF/LOW)
