Byte Blaster Clone for use in Quartus - del90003

Programming an FPGA or CPLD by Parallel Port is possible with appropriate Interface Circuit and cable. Here is an example for loading bytes into an Altera Chip.

Altera - FPGA CPLD Structured ASIC

A project in elektor electronics  -  got me  interested in this. You can try the Quartus Web Edition, and learn some basics of CPLD and FPGA, This page is intended for that..

"The ByteBlastera parallel port download cable is a hardware interface to a standard PC parallel port (also known as an LPT port). This cable channels configuration data to FLEX 10K, FLEX 8000, and FLEX 6000 devices, as well as programming data to MAX 9000, MAX 7000S, and MAX 7000A devices. Because design
changes are downloaded directly to the device, prototyping is easy and multiple design iterations can be accomplished in quick succession

The ByteBlaster cable has a 25-pin male header that connects to the PC parallel port, and a 10-pin female plug that connects to the circuit board. Data is downloaded from the PCs parallel port through the ByteBlaster
download cable to the circuit board via the connections."

The circuit below is the Byte Blaster Schematic. The clone circuit drawn by me is shown far below too.

FPGAs contain an array of programmable logic blocks, and a hierarchy of reconfigurable interconnects that allow the blocks to be "wired together", like many logic gates that can be inter-wired in different configurations.

Logic blocks can be configured to perform complex combinational functions, or merely simple logic gates like AND and XOR. In most FPGAs, logic blocks also include memory elements, which may be simple flip-flops or more complete blocks of memory.
