I've not heard them called "mini" before, but I think the regular Tower 400
was a 68000 machine with ST412 disk interface (the 'MSC' board) and a HPSIO-8
board for serial.
I've got a 700 model - '030 CPU, ECC memory, dual HPSIO-16 boards, Ethernet,
HPMSC SCSI controller, system standby/suspend etc. They're not blindingly
fast (Ethernet response is *really* sluggish), but they're nice enough
machines in a "real computer" kind of way.

The DB15 is the console. The DB9 is for a remote diagnostic modem link (I'm
not sure whether you can get a fully-functional console up on it, and I think
it's stuck at 2400 baud)

1 TxD out
2 RTS out
3 DSR in
4 DTR out
9 RxD in
10 CTS in
11 sig gnd
12 DCD in
Hazy memory says that it might expect 9600 baud, 7E1 by default. I might have
the jumper settings for the serial board that you have - I can take a look if
I think the regular terminal lines might use the same pinouts on your machine
(my 700 has 37-way connectors with four ports over each connector).
> So does anyone have a boot tape
Afraid not... I'd like to hear from anyone who has them too. I've got raw
drive image backups of my machine, but it'd be nice to know that the install
media was out there. I think there are two flavours of boot tape
(unfortunately for me) - one that'll work with 400-6x0 machines, and one
that's specific to the 700 (I've not sure about the 750 and 800).
Note the if you have a BNC connector toward the bottom of the machine at the
back, it's something to do with the power fail detection circuitry. It's not a
Ethernet network connector and plugging it into one would result in
interesting things happening :-)
