Emax

This is an Emax II 2201. 1MB of RAM.

Looks like it was left in storage for a long time.

Bad power switch- bypassed for testing, will replace.
Screwy display- reseated all ICs and we get the good display.

So far so good...
The Floppy drive is failing (CRC errors), so I can put in a slim floppy.
There is no HD- but I have a CF drive for it.

I hear some whistling noises as the floppy is chunking away in the  
headphone outputs.
It may need some work on the PS then or re-cap it.... I can do that too.

It did boot, and I loaded in an Emax 1 disk after several attempts and  
CRC errors on 3 disks.... I hear sounds in the headphones when I press  
keys.

Some of the keys I have to press hard to get a response.

So here are the questions:

1) For the key presses- perhaps some cleaning needs to be performed?
I've never had to do this on my Baldwin IKE / Emax 1, as it was well  
kept.
Any tips in relation to the cleaning process?
It has 3 broken keys, so I would assume during cleaning process that  
would be the best time to replace them, correct?

2) It doesn't appear to have the Stereo upgrade.
Any way I can get this updated to Stereo?

3) I know without the Expander board I certainly  cant get above 2MB.
If I get the ICs to make it 2MB on the main board will it see it, or  
are new PALs required?

Just trying to figure out my options.
Or should I just wait again for something better to come along and  
part this one out.

Any help is appreciated.

Regards,
Ted







Mono sampling.

I dunno. but I will find out.... :-)

So to be clear on what the options are:
1) If it is mono, is there an update to stereo?

2) If it has an expansion board, I can get an eeprom to update to 8M,  
correct?
(ie by using the workaround used to fix scrambled megs posted to the  
group shortly ago..burn a new EEPROM and socket it).

Ted

Congrats! Which model did you get? I see a lot of helpful posts coming  
out of this purchase regardless :)
