A few question on the MAX1000

Hi :)

1/  I recently bought a MKR2UNO to use with my MAX1000
    the mkr2uno has 2 pins named TX/RX  are they connected to the usb port in any way

2/  any example somewhere showing how to use ADC with the MAX10000 ?

3/  I saw links to the schematics but they are all dead 
    if there a link working somewhere
    [I would like to build a base board for the MAX 1000]

4/  if I don't want to use the ADC on MAX1000 is it possible to use these pins
    as standard I/O

5/  I saw some questions about sdram controller, I wrote a replica1 / apple 1  in vhdl
    it contains my SDRAM controller as well as a sram to sdram bridge
    usefull top connect al old 6502/6800/6809 core and probably a z80

1/ USB has no pins named RX/TX, those are referring on mkr2uno that those pins are default UART pins. For MAX1000 they are just regular FPGA IO pins, use anyway you want, not limited to UART

2/ sorry no. Arduino MKR has AIN pins so we connected them to MAX10 ADC capable pins but never used as ADC

3/ I just now checked from our online shop all schematic links work, just download the schematic there

4/ YES, they are regular IO

5/ We are using some open-source SDRAM controller in our test designs, it works well
