Oggetto: [Ql-Users] Dead QL
Hi QL gang,
I fired up my QL this evening and it would stay on the F1/F2 screen, no
matter how hard I press the F1 and F2 keys...
My setup is:
Aurora board
SuperGoldCard
QUBIDE
Minerva MK1
As I said, it would not boot past the welcome screen. Not even the Minerva
timeout to the default F2 works. It would not boot to harddrive, or to
floppy.
This only thing that produce any change on the screen is the CTR,
ALT,SHIFT,TAB combination that makes the screen kind of redraw itself.
I suspect that the SGC battery is dead. Does a dead SGC battery makes the
system un-bootable ? What else can it be ?
Thanks in advance.

I do not have much experience with Auroras as they rarely seem to fail.
I too don't think the failed battery would stop the QL booting. There
is nothing in the SGC startup options that could do that. *All* my SGCs
and GCs have dead batteries (8-)#
MKII Minerva can stop a system booting (a quick double reset bypasses
that) but this is a MKI (no battery).
As Davide suggests, try Qubide and SGC in a working standard QL using
the backplane. Don't forget to enable the expansion on-board 7805
regulators - so easy to forget. Qubide survives, but you only have
seconds before SGC gets fried. One of mine lasted three seconds, but
like sticking ones fingers in a live socket, I wouldn't like to try it
again (another thread (8-)# ).
I forget which QL chips are used in Aurora, but try inserting those from
a good QL.
It is unlikely to be the 8049. Minerva auto boot would bypass that.
The only dodgy 8049 (or replacements) I have seen stop F1/F2.
Good luck,
Tony
