I wish I had seen that on eBay, I was looking to buy one of those, as long as they have the resistance and Ac options installed, that meter is exactly what I would have wanted to buy.
That last IC was in some very cheap IC Socket strip type things . I used to use them a very long time ago here in the UK when I was short of money but they were so poor quality I spent more money and got better ones . It looks like they tried them out -- had trouble so soldered the IC to the sockets --strange . An option was to also buy polythene holders for the strips of contacts . The contacts came as a strip ( like Dupont contacts etc do ) and you cut them into a strip of 4 ,7 ,8 etc and put them into the polythene holder ( or not ) then soldered them in place and then ( & only then ) broke off the strip that joined them all and kept them 0.1 inch spaced .
Max if you get any more 1071/1081 which have the resistance and Ac options please let me know, especially if they are electrically broken, those are my favourite.
