Hi,
I just tried to start my old Atari 1040STF again, after about 30 Years of "Downtime"
The Internal Power Supply starts, ant the voltages are 4.75 V on the 5 V Rail and 12.3 Volts on the 12 V rail, so nothing to write home about, but should work, at least it does not blow anything.
Connecting my SM124 (which also still works) and powering everything up, only a white Box is shown on the SM124....
So, open everything up and reseat all socketed ICs...
Now TOS is booting and shows a screen - wait, I forgot the diskdrive.... Power down, re-connect the drive - the white screen (Box) is all It does now again....
But anyway, I already got a gotek drive with flash-floppy installed - put that in and when it is jupered correctly, also the white box is shown and tos is not booting.... jumpering the gotek to S1 (or S2) and TOS boots again without issues, but no Disk Drive is shown at all.
It is sufficient to detach the data cable of the floppy - does not matter if it is the original Floppy drive or the gotek.... so I don't think power is the issue.
Even "warming up" the powersupply and give it a reset after a couple of minutes does not change anything..
Does anyone know this behaviour?
Don't know why initiliazing an (even dead old) floppy should freeze the system like that....
Cheers
Ford
