A quick GOOGLE search shows several Tek hybrids which have 165- part numbers.

Can anyone identify them My goal is to unlock the secret of how the AM503B works and ultimately to find the schematic, theory of operation, maintenance manual, etc. so we can finally fix the plugins. I am looking into the unusual parts in them at the moment and these 3 parts are the most puzzling. 1) 160-9569-02. My wild guess is it is a PROM holding a program. For what processor it might be I have no clue. 2) 165-2456-00. This is a Hypcon package from MAXTEK. I would guess it is the ASIC running everything that isn't in discrete transistors or TTL glue logic. I cannot find any reference to these two entire categories of parts: I have no parts catalogs that show 160-xxxx-yy or 165-xxxx-yy parts. I don't even know what a 160 or 165 part could be. Not even a wild guess. I don't even know if there is a catalog of those kinds of parts. Does anyone know? 3) Finally I have what looks to be a specialized microprocessor (wild ass guess). This would be an IMP (International Microelectronic Products) I10412-01. It is a 28 pin SOIC. They are no longer in business as near as I can tell. That isn't a Tek part. It is not a company I ever heard of. There is virtually no reference to it anywhere on the internet except it might be called a "daculator" (that is not a misprint as far as I know) and it might be related to a Tek 156-6224-00. All Microprocessor, TTL, special function, etc, etc chips start with 156-xxxx-yy but my Tek IC parts catalog stops around 156-3000-yy so I have no information on it. |
