working condition ? what does it mean ?
Why have you decided to replace the HSA ?

have you moved the ROM ?
What about terminal log with the new PCB ?
have you eliminated TTL cable problems ?

hello jol,
I again and again i tried the short-pin process and now i got the terminal.

At present i can access the F3 T>
but the file translator 28h is corrupted or the sector is bad. so that i cant take the bakup of that file 28h or the translator regen also not functioning.
I could able to backup 1B,35h,93h system files...
And for a while, just now i got the all the ID and capacity serial everything i got . but when i power off/ON it comes on previous stage again.
I feel that its totally related to translator.May be one of the head is weak.

anyone have any suggestion except the again head replacement

Please give some idea...

Did you try disabling everything in system file 93 and writing it back to the drive? That might go a long way toward stabilizing it so you can work with it. Also, what tools do you have available to work with, PC-3000?

hello, did you try to import the head adaptives from the donor disk? And this function will be a helper.
