Problems with LC III
Hi, Can anyone help me with problem with my classic Macintosh LC III please ?
It worked fine when i bought it about a year ago but the started giving the dreaded booting problem due to a failed battery. At some point I decided to re-seat the ROMS (there are two - Hi & Lo) by removing them and re-inserting them into the sockets.
The sockets have two extra connectors making them longer then the ROM chips. I stupidly inserted the ROMS badly, instead of closest to the expansion bay i inserted them closest to the other side.
The ROMS got really hot to touch and i switched the LC III off and put them in properly.
Since then I have TWO problems:
A: With the FPU in place, when I switch the Mac on i get No display and no sounds... Nothing.
B: Without the FPU I still get No display and No chime sound but i DO get the sound from the speaker which it used to make just before the chime.
I have since replaced the battery with a brand new one, but I am still having these problems. I am suspecting that the FPU is probably damaged and so are the ROMS.
I have tried resetting the PRAM by holding down the appropriate keys but have had no luck.
Is there anything else I can try ?
If there is nothing else I can try would anyone know where I can get a set of ROMS or maybe somebody who can reprogramm a new set of ROMS for me ? Since i own the original ROMS and Apple no longer supports the machine would it be legal to have a new set reprogrammed ?
Any help will be greatly appreciated.
Thanks
