Anyone with an Emax HD/Plus look here please :-).

[12bit]

Hey fellow Emaxers.

My Emax Plus has always been acting a little weird - and I am curious to know if it is supposed to or not.

When I power it up it is stuck with the display showing 'Emax Diagnostics' for about 15 - 30 seconds while the Analog Processing LED is on - then continues to load fine from floppy.

Is this normal behaviour ? If not does anyone know what to look for ?

See this video showing the issus:

Could well be another PSU issue.. the fact that it sits for a while does suggest it may be Caps coming up to charge.

First and easiest thing to test it is try disconnecting the HD and boot from floppy. this will lower the startup load on the PSU and if it boots normally then most likely points at a re-cap of the PSU as the fix.

Hope this helps

Seems like normal behaviour to me...
Or mine is having problems too 

My Emax SE did not do this until I upgraded it to SCSI (=Plus) with Ted Summer's upgrade kit; it's doing this even without any HD or ZIP/CF device connected to the PSU.
This change in behaviour of the Emax was part of the SCSI upgrade explanation on some website, so I was (and still am) not concerned.

I should double-check if my factory Emax Plus is also doing this, but I don't think so.

Is yours an upgraded one or a factory one ? (333 cpu board inside ?)

Well - The funny thing is that it has the 333 CPU board inside (with Rambird saying 'No more floppies' and everything) with connectors to both internal and external SCSI on-board and the original blue Emu Systems 25 pin SCSI port on the back.
The panel does NOT suggest that it is a HD model though as you can see - just a 'normal' SE model.

I guess I will leave it at this then.
If you have the same 'issue' I will not give it more thought anymore.

I saw the explanation you're referring too on Emulatorarchive as well - but I was not sure if it would do this after the initial boot up - but it does.

Thanks for the information - most helpful.

Thanks to you as well. I actually tried this but it did not change anything. The video was shot with no internal or external SCSI connected.
When I put in my other CPU board (different revision - not HD) the problem is gone. I would prefer using the HD board though :-)

Thanks !
