Or, is it correct to refer to anything between DA and DB as "DB"?? (such as "DB-23" on Amiga? Yes, I dremeled a DB25 to fit.) On Sat, 12 Aug 2023, Tony Duell via cctalk wrote: I've seen DF19 and DG23, which makes sense. Originally there were the DA to DD shell sizes. The DE9 came later and

While probably unrelated, the mentioning of 3 rows of pins did remind me about what I recently learned about the 1973 IBM SCAMP... On the back side of it, it has a 3-row of 14-13-14 female pins (next to what became a DB25 connector - did DEC come up with DB25??). Was curious if anything ideas on
