Next up is a Tatung Einstein
Its been doing its duty for the last 12 months, booting Elite from disk for the amusement of the visitors but is now locking up during boot.
If no disk is present, it starts up in the MOS fine. Disk tested on my machine and works fine.
Diag ROM installed and no faults noted
So a disk fault ?
From MOS you can read a disk. Command R 100 200 0000 0 reads 100h bytes from track 0 sector 0 head 0 and then T 0100 0200 shows the memory. Did this and the contents of sector 0 track 0 read perfectly into memory so no fault with disk drive.
