Title: Emulator III screen BOXES dead Post by: tron23 on May 26, 2013, 01:26:36 PM Hello everybody,
I was in the restricting situation of a blank / 2 lines of boxes screen on the EIII. I almost took all the cards apart and did some cleaning on the various connections, also reseated the SCSI chip, checked the voltages etc. as I have previously been reading on the great forum. With some luck and praying the machine now is in a better state, scanning floppy, scsi chain, mounting drives and comes up with the message cant load system. I tried an old OS floppy I have made with no luck, comes up with the message FD DATA CRC ERROR is this just a matter of corrupted floppy and HDD?? At the same time? I have no other way of loading making a system disk so I am stuck any suggestions???

It was a faulty RAM module, in the process of cleaning them I had swapped positions in these placing the faulty chip in the very first socket, where the system is loaded!!? what an idiot!! ???

Those old RAM chips!!!
