New ContributorCan you tell me the connection diagram of this chip and how I can connect it to a USB Blaster? Additionally, do you know how I can read the data inside the chip and which device I need? I saw a video on YouTube, where the data inside the Alter Max chip was read via Quartus by connecting the USB Blaster to a special circuit to which the Alter Max was connected.
Frequent ContributorYou can get the device pinout files here ...
To attach a USB Blaster you just need to connect JTAG TDI, TDO, TMS, TCK to the USB Blaster 10pin connector.
Along with the appropriate power and ground connections as well. The USB Blaster datasheet describes the standard
2x5pin 100mil connector pinout.
QuartusII 13.0sp1/13.1 are still online and will allow you to (re)program the device. Reading the device program back for the MAX series was deprecated in Quartus so is not possible to do with any currently available version of Quartus using a USB Blaster.
Xeltek has a programmer that says it supports your device (the IS01):

Whether it fully supports reading device contents or not I don't know. You will have to review the documentation or contact them.
