[Coco] RS-232 Pak Back to Stock

[John E. Bielak]

I picked up a deluxe RS-232 pak thats somewhat modified that I'm trying 
to put back to stock.

The changes:
- The ROM has been cut out
- The trace for pin 4 cartridge edge connector has been cut and there is 
a wire going out to an external connecter
- There's a jumper between E1 and E2
- A jumper appears to have been removed from E3 and E4

Obviously,  I need to desolder the old ROM pins, put a socket in, drop 
in a 4K EPROM (2732?) with the cart image, and then reconnect trace to 
connector pin 4, but I don't know what to do with the E1 - E4 jumpers. 
I've Googled around and the only examples I've been able to find are 
other modded boards, nothing that appears stock.
