What next! now it doesn't boot up

[dresda]

I turn on the machine and it says:
Sram (B; free space = 1)
press F1 to display function menu.
Then I set up sram and say yes,yes,yes,
It check cylinder and head, the just sits there.
I press help or esc, button a few times and it loads up and runs.
It will do this every time I kill the power.
The Centurion 1 path says
Rom; a;\rom\
Ram; b\ram
Parts; b;\
Display; D;\
Floppy;C \

I also need to get into the parameters to change the homing sequence it now zero's at the next grid and not on the gogs.

It says 3.5 volts, has anybody used a 3.6 volt battery, seems like the only one I can find.

Sram freespace = -1 indicates a dead battery on the simdisk. While you have the simdisk board out of the control, locate the bank of dipswitches and note their original position. Try toggling the dipswitches back and forth a few times.

[dresda]

What will that do, toggling the switches back and forth?
Should I not just replace the battery.

Yes, replace the battery first. Then toogle the dipswitches. Sometimes by toggling the switches it causes the simdisk card to respond more effectively.
