So it doesn't appear that my new EII rev 0 has the rs422 daughter  
board installed. I wanted to confirm though because I don't really  
know what I'm looking for. Here are some pics I took of the back of  
the jack from a few different angles:

Second question, is there any chance something like this would work as  
a substitute?

I really don't think so. In order to "upgrade" to 422 there have LOTS of modifications to be made on the digital board itself. Lots of kludges - you can read about that in the EII's service manual (don't know which pages exactly). If you're a GOOD technician, you may try it. I wouldn't even dare in a million years, as I'm no tech at all, and the modifications are heavy...

SOrry bout that, but maybe I'm wrong..........

Is the service manual in the files section? I didn't see anything called "service manual". 

I have a friend who is an electrical engineer (used to work for JBL) and am hoping to enlist his help. Would like to gather as much info as possible for him though. If anyone else has done this, I would really love to hear how it went - if they ran into any snafus.

I have this 500 disk library now. Much of it is pro quality custom samples (Fleetwood Mac, blah blah blah) and I really want to get it backed up before it turns into a pumpkin. Would be totally willing to share the resulting files with anyone who can help.

Thanks,
Jeremy

There are three documents in the Files/Technical section that may help your tech:

EmulatorIIRS422Spec.pdf 
EII RS422 Schematic.pdf
EmulatorIISchematics.pdf
 
There may be pictures that help in the Photos/Emulator-II Technical section.

The official service manual is a 100mb pdf IIRC: too big to host in the files section. Youll have to source a copy elsewhere off-site.

Probably need to wait for Rob or someone else with specific RS422 knowledge to fill in further specifics.

As for shipping from CA to NY, yes put scrap disks in the drives and latch them. Best advice is to use a sturdy padded locking roadcase and make sure it cant "walk around" inside. Pack roadcase inside an outer carton, ship insured, and cross your fingers. ;)

Hope this helps somewhat.

Thanks! If anyone is able to upload the service manual somehow (yousendit?), I would be much obliged. Thanks for the packing advice.

Pics and a list would be great! Did you install the Mac board yourself or did it come to you that way?

Thanks a bunch for this. So as I thought, mine does not have the daughter board. It is definitely rev 0 though. List of parts would be great thanks.

BTW, I noticed someone is parting out an EII+HD on Ebay. It would probably be too much to hope that I could just replace the whole board with this:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190296238493

I'm sure there would be some incompatibility right?

Rev. 1 digital boards use different IC's for IC108 and IC132, which are actually 8-pin vs. 7-pin in the Rev.0 boards. The Mac Int board itself will not fit in a Rev.1 board due to this pin difference. There are also many more "blue" thin connecting wires on the PCB bottom of a Rev.0 digital boards. I'm not sure where to source the "AM26L" IC's or an equivalent, but will look into it. I will post a list of parts as well, hope this helps a bit!

Thanks! I'm not sure I follow you though. Specifically this part:

If it's a rev 1, it doesn't need any mods to use the Mac connection  
right? I guess my question is, would it be possibly to just swap out  
my entire board for the one on Ebay and have a working RS422  
connection? That sounds a bit too simple though... Would it require  
some mods to the rev 1 board for compatibility? Would that be more  
complicated than modding the rev 0 myself.

Jeremy

Ahh, I did not know it was also an issue with some rev 1s. Apologies.  
So if these mods were made already, I could just swap out the boards?  
Or would I just be able to use the connection jack? If they were not I  
would have to do steps 1-5 below? Is that correct?

Hi
Be very careful with this. Please don't make the mods until you are
absolutely sure RS422 does not work properly.
Most Emulator II's work with RS422 with no problem.
Simple way is to check the serial number. 950 to 1100 may require the mod.

Regards
Rob

Me too.  I've been thinking of seeking a good home for my mintish EII+, but the idea of shipping it is daunting.  What are your experiences with shipping EIIs?  Any advice?

Thanks,

Wow, that is exciting news! Obviously there are a few ifs, but this  
prospect seems MUCH easier than upgrading the rev 0 board. I've asked  
the seller about the serial. Hopefully I will hear back from him  
before the auction ends later today.

If I install it without the mods, am I risking anything other than the  
Mac connection not working?

Are there other risks to other components that I should be aware of  
(if something is wrong with the rev 1 board or something)? I want to  
make sure I'm taking every possibly precaution here.

Very sad indeed to see it trashed. Hopefully some current owners will  
be able resurrect and prolong the life of theirs as a result.

The guy replied. The serial number is 2232 so should be good there. He also said he couldn't see any cracks and sent me a higher res photo. I does look in good shape. 

He said that the empty Z80A socket is actually used for a connector to the scsi board on this model (it's a +HD). Strange. Makes me wonder again if that would pose compatibility issues.

Man, outbid! Sold for $160. I guess it's back to the DIY approach...

Thanks for the help and input.

Did anybody from the group buy it?

Man, those parts go for pretty much....

Use to work for a Emu dealer back in the day.
Emu Systems use to  ship EII with the two end C keys removed because 
they where likely to be damaged during shipping.
Use to have snap in those keys when we received then from the factory.
I know that when I sent mine back to the factory many years ago I was 
instructed to remove those two keys prior to shipping.
