Driver:InterPro

Intergraph InterPro

The Intergraph InterPro brand name refers to a range of computers featuring the CLIPPER processor, and running CLIX, a port of UNIX System V release 3.1.

Status

The MAME driver for the InterPro is a work in progress, and is currently capable of booting and running the CLIX operating system and some software for the InterPro 2020 configuration. Some other models are capable of booting the diagnostic monitor and disk-based diagnostic utilities, but not yet able to install or run CLIX.

Hardware

Models

The InterPro range consists of 5 distinct generations or families, named after gemstones. The system models within each family share a common architecture and features, usually differing only by CPU type and clock speed.

System Families

Year	Family	Models	CPU	I/O Processor
1986	Amethyst	32C/100/200 300	C100	80186 80386
1988	Topaz	3000/4000/5000	C300/C300Plus	80386
1990	Emerald	6000/6100/6200/6500 6600	C300/C300Plus C4
1990	Turquoise	2000	C300
1992	Sapphire	2400/6400 2500/2700/2800/6700/6800	C4T C4I

For Emerald, Turquoise and Sapphire systems, the four-digit model number encodes some aspects of the original system configuration, and breaks down as follows.

Model Numbering

Position	Purpose	Values
1	Case	2=desktop, 6=minicase
2	CPU	0=C300, 4=C4T, 6=C4, 5/7/8=C4I
3	Graphics	0=none, 3=MMG, 5=GTDB, 4=EDGE-1, 8=EDGE-2
4	Backplane	0=standard, 5/7/9=?

InterPro minicase

As examples using this encoding, an InterPro 2020 is a desktop C300 system fitted with MMG graphics, while an InterPro 6880 is a minicase C4I system with EDGE-2 graphics. Systems configured without graphics are typically fitted with a serial terminal, and branded InterServe rather than InterPro. This model numbering and branding applies to the system cases, but of course changing graphics options will cause a system's software-identified model number to change.

Cards

SMT094, an EDGE-2 Plus graphics card

A range of approximately 150 installable cards were produced for the InterPro family. The most common and important of these included the system mainboards and several different graphics options, however a range of less common cards supported functions such as video capture, SCSI expansion, networking and a VME bridge were available. Desktop InterPro systems support the installation of two cards in addition to the main board, using an interface referred to as CBUS. Larger systems supported either 5 or 12 slots with an interface referred to as SRX, which is physically incompatible with CBUS.

Regardless of type, card names are typically prefixed by the letter M, followed by PCB or SMT (the latter designation indicating a surface-mount board), followed by a 3-digit board type. Boards are also typically marked with a single alphabetic revision number and an ECO (engineering change order) level recording hardware-level fixes.

Examples include MPCB963, which is described as "2000 Graphics f/1 1Mp Monitor", and MSMT094, which is an "EDGE-2 Plus Processor f/1 2Mp-FB".

Installing CLIX

Prepare Hard Disk

Use the MAME chdman utility to prepare a new CHD for the operating system installation. Various different hard disk capacities should work but have not been extensively tested yet. The actual geometry should not matter at all, but the vendor and model strings are queried by the software and may affect the installation process, and there may be some impact if they do not match existing entries in the delivered CLIX /etc/disktab file.

The identifier string should consist of an 8 character vendor name, 16 character model number, and 4 character version number, all left justified and padded with spaces.
