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) Console pinouts: 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 you want. 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). 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 :-)
