HI~XD 

 help me... please...   I don't know how I use Altera Flex10K50ETC-144-3 on Quartus2.   My board is very old version, It made 7years ago. but, I have to upgrade it.   So, I installed Quartus2 4.0. and I knew that it don't assist the device. There are a lot of Flex10K device, but Flex10K50ETC-144-3 is not exist.   erm... I saw Flex10K50STC-144-1 in selecting device combo box.   If I select Flex10K50STC-144-1, Can I use Flex10K50ETC-144-3 ??? :D

You might be better off downloading an old version of MaxPlus2. 

 Something from around 1999 seems OK v9.23 perhaps  Have a look at the versions here  https://www.altera.com/support/software/download/service_packs/maxplus2/upd-maxplus2_index.jsp

The Flex 10KE family is supported in Quartus, even though you can't see the selection in the pull-down menus. 

 Just use a text editor to manually edit your QSF file. Set your family to "FLEX10KE" and your device to "EPF10K50ETC144-3":  set_global_assignment -name FAMILY "FLEX10KE" set_global_assignment -name DEVICE "EPF10K50ETC144-3"  Don't edit the QSF while your project is open.
