Hello all,

Dave McMurtrie contributed a nice pile of PET option rom images to the 
funet/zimmers archive _at_ http://www.zimmers.net/.../computers/pet/other/index.html

I had no trouble identifying and classifying most of them. However, there were 
several that I could either not get working, properly disassembled,, or just 
couldn't identify.  This is fairly new to me, so I created a special place for 
them here:
http://www.zimmers.net/ano.../pub/cbm/firmware/misc/unknown/

If anyone out there enjoys digital archeology, I'd ask you to give a second or 
third opinion on some of those unknown roms. It's possible the eproms were just 
corrupt or unreadable, but I'd sure like someone else to concur before I throw 
any of the images out.
