What uC you plan to program ?

If you tryed that lpt programmers change in BIOS parameter for lpt port to SPP (Standard Parallel Port).
 

See this LPT programmer with 74LVC244 or 74HC244 (cant 74HCT244) :

Yes I use all programmers what I post it, and all working. This from post 5 I use to program firmware uC for 89 serie programmer 89C2051/S51/S52/S53 programmer (sunrom).
 

No my friend. This programmer working like a charm.



Check in BIOS LPT port is SPP (Standard Parallel Port), check all connections.
 

what is this error mean :
program verify error @address 003D
Data read = 80
Prog data =90

Check data line on the MPU "you should see pulse on the two data lines while you programing" (this operation very fast).
Check MPU on other programmer!
Check if you can erase MPU or not by your programmer,
Check the TTL IC if fully compatible with your design or not.
 

To this I still don't understand, need you to help me.
