(FWIW, the following exist.
Normal High Density
DE9 DE15
DA15 DA26
DB25 DB44
DC37 DC62
DD50
I beleive other ones have existed for special applications (particularly high
density DC shells with a few more than 62 pins!)
Some typical uses :
DE9 : PC/AT serial port, Apple //e gamess port, PC MDA/CGA/EGA video
DA15 : AUI port, PC Joystick port, Mac video, Beeb analogue port
DB25 : Real RS232 port, PC Centronics port, Mac SCSI port
DC37 : PC ex4ernal floppy connector, Canon CX-VDO interface
DD50 : (old) Sun SCSI port
DE15 : PC VGA video
DA26 : never seen it used
DB44 : Ditto
DC62 : PC Expansion chassis connector
THey're used for plenty of other things, so please don't moan that I've
not mentioned your favourite machine there (I suspect if I said things
like 'DA15 : PERQ video sync/keboard/mouse signals, it would help
nobody). I am trying to mention machines that you're likely to have seen.
I';ve also seen DF19 (Atari ST DMA port?) and DG23 (Amiga video
connector) refered to as such, but I am not sure those are official.
Actually, it's a DA15 (the DB15 doesn't
exist AFAIK), and normally has the
standard slidelock latches.
When you say DA-15, do you mean a connector the same size as that of a
9-pin serial cable, or the next size up as on a typical Macintosh display?
If they are both referred to as DA, why? If not, what is the proper
designation (since DB is the typical 25-pin shell size)?
The letter gives the shell size.
