i need to flash some w29ee512 chips with a latest firmware for some scsi to ide cards

im using the willem pcb50b programmer

i use the plcc32 socket i can read the chips but cant verify or erase or flash them

i check the software protect switch to unprotect them

but get errors when trying to do other functions

if i do the id the manufacturer does not come up

or its id

is there a programmer that can identify the chip and do the correct
hardware unprotect 3 byte instruction so that htey can be erased and flashed with the latest firmware

any help would be great

and whats the best programmer for me as i also have a load of 27c040 chips to burn
