"Those pesky db15 ports" that I
remembered a couple of terminals that I hauled home recently.
The terminals have a DB15 for both the monitor and keyboard.
Anyway, I hauled home a couple of IBM 3101 terminals. They
consist of a base unit, a monitor, and a keyboard. From the ID
tags they appear to be around 1980 vintage.
Unusually for IBM stuff at this date, they are both (a) designed to plug
into a mainframe and (b) ASCII. AFAIK, they were used as the system
console on some of the big 370 derivatives at that date (4300 series and
3080 series)
If I had space, I'd be tempted to offer one a home. But I haven't :-(

PS Are you sure the connectors aren't DA15?

You mean I'm not the olnly classiccmp member to have a space problem...
Seriously, other than moving (or collecting pocket calculators), is there
a cure to having more computers than floorspace for them?

PS Are you sure the connectors aren't DA15?
Almost certainly they are. There is no connector called a DB15 in _any_
catalogue I've looked in. The letter after the 'D' specifies the shell
size - from memory, the standard ones are :
DE9 (PC serial port, Atari joystick, etc)
DA15 (Ethernet AUI, PC games port, etc) -- The one we're talking about
DB25 (Standard RS232, PC printer port, etc)
DC37 (PC external disk port, Canon CX engine interface, etc)
DD50 (Sun SCSI port, etc)
The high-density ones are :
DE15 (PC VGA monitor)
DA?? (Never seen it)
DB44 (Never seen it used, but it's in the catalogues)
DC62 (PC expansion cabinet, etc)

Sorry to differ from my more knowledgeable co-respondents,
but I had an XT clone which had a DB15 RS2 serial port. I searched in vain to find an adaptor for an
external modem
and finally installed an internal one. 2 rows in a D shell.
Adaptor == DA15 connector, DB25 connector, piece of wire, solder...
