HP 9836 SIMMs & SMS Sprint was Re: New Finds Today

Today I had a bit of time to look at some of the smaller items that I picked up yesterday. One of them is a small box with a 28 pin ZIF socket on it and a ribbon cable coming out of it. It's marked "Sprint" and "SMS". I did some searching on the net and I believe that it's part of a programmer made by SMS Gmbh in Germany but I couldn't find any details on what kind of ICs that it programmed. They have since been bought out by Data I/O and their programmers have be discontinued. Does anyone know more about their stuff? One of the odd things about this unit is that it has a 5 position DIP switch on it marked "filter". Anyone know what that's for? Also found an interesting memory card in one of the HP 9836s. This one is made by Newport Digital and it holds four 30 pin memory SIMMs. I haven't had time to play with it yet and I don't know how much memory is on but it appears to be 1 Mb. Does anyone know anything about these? I went back today and picked up more stuff but that's a story for another day. Joe
