Paalala lng ka symb, be sure na hindi kayo magkamali sa tapping ng pins ng 25fl128 mag ooverheat po yan at masisira wala pa nman tayong pagkukunan dito. Kung gusto nyo ma test ang flasher nyo bili rin kayo ng 25t80 na eeprom kasi mura lng yun, wag yung 25fl ang gawin nyong pang trial n error.
Kung effective na po yung flasher be sure na makapag dump kayo ng tama kasi may instances kasi na may loscon sa ginawa nyong flasher ang mangyayari ay nakakapag dump nga kayo pero may error yung data na nakuha nyo. Mag dump kayo ng marami para iwas error at tingnan nyo ang pagkakaiba, kahit minor checking sa mga hex data ok na yun...
At sa pag reprogram nman dapat wala kayong gawin iba sa desktop nyo kasi pwede itong maka delay sa pag write sa chip.
Again in Flashing no.1 rule ay dapat naka full power po kayo no interruption pwede kasi ito maka sira sa chip. Hindi kasi ito katulad ng USB type na programmer na mabilis mag write n read kaya less lng chance na magka error kasi mabilis siya.
REMEMBER THIS ERASE NYO MUNA ANG LAMAN NG CHIP PAG MAG REPROGRAM NA KAYO.

Bakit may nagsabi ba na EEPROM yung 74LS? :P
I said STAY AWAY FROM LS....74LS244 kasi sa modern MOBO di gumagana yung LS..
Get the HC type..

Maybe a HISPEED USB? sinu may gusto?
^^ This BEAST can program in 50-55 seconds...

thanks sa info sir RBT
patay paano yan nakabili na ako ng 74LS
Try nyo lang po muna...
If your port can deliver enough voltage swing then you're lucky..
If ayaw mag connect or erroneous yung operation..dapat talaga HC gamitin mo...
One more thing..wag mag aksaya ng panahon sa USB to LPT converter....promised I've been there...
EDIT:
Sa mga gusto magpagawa I have 6 pcs. left...unahan na lang po..PM me...
