Emax

Hi again,

One more question - is it possible that the symptoms I mentioned in my previous message are caused by a faulty power supply? Frankly I'd rather it were disk failure. . . .

Thanks,

In that case I am frankly not particularly bothered about hot-swappability.

It looks like the CF drive is probably my best option.

    No, the Emax II can handle 540MB. The Emax (I) can only handle 20MB of
  banks.

I would be almost sure that is your problem. I've got the same issue into my EMAX II HD. Check the HD power supply sockets. They are prone to open the female contacts and therefore they loose contact sometimes. 
So, the disk tends to stop and go again with no apparently reason.

Thanks. I really hope that's all it is :)

I'll open it up and have a look as soon as possible. 

Silly question time: how does it open up? I don't want to remove the wrong screws and find that I've removed the motherboard or something . . .

I've never had one of these open before, so is there anything I should know before I do? I assume from the sheer size of the thing that it's not exactly cramped in there?

Thanks,

Daniel

It is really easy to gain access to the HD. Put the emax upside down (a soft cloth under it is recommended. Then remove all the screens on the rear cover (except the ones for the black "legs").

Then you will gain access to the Power Supply, Analog Board, Digital Board, HD and Floppy drive. (except the buttons panel, all the boards are easily reachable).

Check the HD power supply wires. Please take special care if you pull up the Emax Power supply output socket (three groups of four wires). A big manufacturing fault is that it has not polarity on the socket, so you could put it back reversed by mistake ... ( and it is talking one who did it once, luckily the emax didn't blow up, it stood for over a minute with reversed wires and neither the digital board nor the power supply suffered any damage, I still can't believe it :)

Grounding yourself is highly recommended every time you open a keyboard. You could graze some chip, and if static is in your hand, the chip can get fried.

Hello,

Thanks for the instructions and advice.

It appears you were right. I tightened the power connector to the hard disk and now it seems to be working OK. Inside, it has to be one of the neatest layouts that I have ever seen. Obviously being huge helps but it looks like a very high-quality piece of equipment.

Somebody has fastened the hard disk to the base plate with a pair of cable ties. The PO said something about this being done because in the original arrangement the HD was upside down and this caused problems. Is there anything in this? Personally I wouldn't be surprised if this is at least part of the problem I was having - maybe it got joggled when it was in the boot of my car on Friday.

Thanks again,

Daniel

that inspire me to a question i got the emax 1 rev 2 and i think my disc drive is about to die..can i replace it with a regular scsi zip drive?

I know this must have been discussed in the past, but have a look at this prophet VS and scroll for the Emu SP-12, can someone more technically inclined point out the model that might work with the Emax Rack?

That would be so great.

 

Thanks

CFAH1602C-TMI-JT
crysal fonts this has the blue screen its the same spec as the powertip one

but it is 13.6 mm deep where as the old 1 is 8 mm deep

if its the rack you have to modify to get the correct voltage for pin 3 

you have to remove the inverter chip and both caps then you have to link the 5v of the inverter chip input to the in leg of the trim pot then you have to replace the cap on the out going leg  but it has to be reverse polarity as it was doing -5 vdc before where it shows a + sign on the pcb you have to put the - leg of the cap and the positive leg where the - leg was this

is for the 5v operation now use the trim pot to vary the contrast of the lcd display

also you have to extend all the buttons on the emax and the 2 sliders due to the lcd being 6-7 mm bigger

than the last 1
