Introduced alongside the 9000/360 in 1988,
this is one of the later series 300 machines. It features a 33MHz
Motorola 68030 CPU with 8MB of RAM on the CPU card, upgradable to 48MB
of RAM with a daughterboard that attaches to the CPU card.
The CPU card itself (including any memory daughterboard) occupies only two of the four DIO-II slots available in the chassis and has no I/O itself.
A minimal set of I/O is normally provided by a System Interface or Human Interface Card which occupies the third DIO-II slot. My machine has a 98562-56533 which has:
If the machine doesn't have a graphics card (or it does, but you don't want to use it), you can instead use a serial console. In order to do this, you need to set the REM switch on the HPIB/RS232 switch block on the System Interface/Human Interface card to ON.
For connecting your PC running a terminal emulator to the RS-232 port on this card, just use a normal straight-through serial cable. A null-modem cable is not required and will not work.
I have only one of these, which is configured with an expander box
containing four DIO-I slots populated with 98642A ASYNC MUX cards. The
main chassis also has a second NIC, a 98643A, in its single DIO-I slot.
The machine was originally owned by Waikato University and was named Athens. The Computer Information card I received with it gives the model as 370/98579B COMPUTER and lists its factory installed boards as:
And there is a second Computer Information Card for the expander, giving its model as 98568A#132 EXPANDER with no factory installed boards.
The machine appears to be configured with 8MB of RAM currently, which suggests that the 8MB RAM card may not be working.
I originally got this machine as part of a large lot of HP9000 bits, but due to a lack of HP-IB drives (there is no SCSI interface) I've never been able to do much with it. In March 2025 I gave it a good cleaning and replaced some bad capacitors in the PSU getting it back running again as can be seen in the screenshot of K95 above. My plans for it from here are to either network boot NetBSD on it, or perhaps try booting HP-UX from an emulated HP-IB drive.
