I went to an estate sale yesterday and picked up a cheap but dirty model 4 26-1067, 64k with two floppy drives. It had been stored in the original owner's garage with the official plastic dust covers on it (and the printer and cassette). I didn't need it, but they were basically giving it away. I already have a mint Model 4 and a Model4P. From the photo i was hoping it was a model 3 (was covered in dust cover). but i got it.
It popped and smoked a little when i fired it up from the back right. two safety caps were cracked/blown, so i clipped them. From there i seemed to be getting stable voltages with no other work...yet.
It powers up fine, display (grey) looks fine. holding break gets me to the cass? and memory? prompts and it boots to whatever basic that is. It came with a box of disks including a Model 4 TRS-DOS disk, but when i boot with it in the bottom drive it would not get past a diskette? prompt.
I pulled it apart, cleaned and lubricated both drives fairly well. Also cleaned all the drive connectors. Still only get the diskette? message.
I also have a set of Ira's TRS-80 disks including 3 or 4 flavors of model 4 dos disks. same issue, diskette? display.
Any advice on what to try or check next?
Thanks
