3016 PET and BTX Decoder ROMs

I have an English 3016 here. Inside there are EPROMs labelled B, C, D, E
and F and a sixth one in the position two sockets down from B. There is no
label on this final EPROM and the socket in between these two is empty. Is
this normal for a 2016 PET? The DRAMs are ceramic but I guess that's quite
normal for a PET.

Other news is that I will upload BTX decoder ROMs from both the type I and
type II decoders. The type I is large and looks like a true Commodore
product. The type II is REU-shaped and has a label saying 'SIEMENS' in the
space on the underside. It is by far the more interesting device as it
contains 64K of DRAM (2 41464 chips) and a 6803 microcontroller with
built-in serial port, parallel port and hardware multiply instruction.
