Yeah, what you have there is a Motorola R-1801 prom programmer
for moto's older PROM based radio products.  I don't think that thing is
even supported anymore, but I do have a manual you can borrow. . . .

  At a thrift I got a very heavy black case with a
Motorola
 Reader/Programmer in the top half and a Digital Analyzer/Controller in 
the bottom
  half. Mounted on the top cover is a Motorola RTL-5820A
PROM socket and
 there is a spare one store in the cover RTL-5821, There are also 
several cables
  in this storage area. I got no manuals with it and
would like more
 information if someone has worked with one of these before?
