The programmer VP-980 didn’t support K8Q2815UQB, the new series programmer can support this chip, like VP-990.
About the chip MX29GL128, please swap the high-low byte with 16byte mode in the buffer Editor.

cannot progam 48 pin TSOP in DIP42 Reply  
I use a 27c800 42 DIP socket type. I want to use a AM29F800B 48 pin TSOP on a 42 pin adapter instead. I created a 42 pin DIP adapter with the 29F800B TSOP and tried to program it in the Wellon 380 programmer. it can do a blankcheck fine and a read fine but not a write.


Last post : Re:cannot progam 48 pin TSOP in DIP42 Reply: kipper2k
Thanks for the reply. Due to the chip being soldered onto the 42pin adapter board your adapter would be of no use so i will make an adapter board for it. I am assuming that the adapter board you mentioned is a pin for pin adapter ( 1 to 1, 2 to 2 etc) ?

Reading Test vectors in JED file ? Reply  
Running the software in demo mode, I can select PLDs but the JED
load does not show the vectors ?
Q: Can the VP290/VP390/VP590 be able to read vectors within the JED file, like other programmers.
This is a summary of correct Vector support :
1) Vectors should read within JED read
2) Edited vectors should save with JED information.
3) Vector Test should be in Auto-List
4) Vector test should have user Vcc define
*V0001 01111X111N0HHHHHHHHN
*V0002 C1111X111N0HLLLLLHHN
Last post : Re:Reading Test vectors in JED file ? Reply: jg
Confirming new update 4.5.1 fixes these issues

* Can now load CUPL Vector information
* Vector limit has increased to 3000, from 100.
  (loading is slow, but for < 3000, it works)
* "K" inverted clock support has been added.
