RAM  480 MB  (Max. 480 MB)
SYSTEM BUS WIDTH 32 bit
SCSI BUS 1 x SCSI-2 (5 MB/s)
OPTION BUS 3 x TurboChannel slots running @25MHz
GRAPHICS PMAG-F 96-plane 1280x1024 @66Hz
HARD DISK DRIVE 9.1 GB 7200 RPM (in external BA42 box)
CD-ROM DRIVE DEC RDD42 SCSI-1 2x (in external BA42 box)

COMMENTS ULTRIX on this machine is very fast. The OS boots up in less than a minute. Useable with X11. The graphics board is very cool, it takes up 3 TC slots.
ESTIMATED PRICE '93 (excl. modern SCSI disk)
$70,000 (or even more, because high-end DECstations came with about 32MB RAM, and this system has maximum amount of RAM)

History and other comments

This /260 had been used as a file server and boot server for 4 diskless clients (3 x VXT2000 and 1 x DECstation 2100). It was given to me for free, the summer of '99. Originally it came with a PMAGB-BA graphics card and 2 x BA42 Storage Expansion boxes (2 x RZ56, 1 x RZ55 and 1 x RZ26 disks). After getting to know this machine, I got interested in DEC hardware.

Later, the year 2001, I acquired a PMAG-F graphics board for the machine. If you haven't seen a *real* high-end 3D graphics board from the beginning of the 90's, then I suggest you take a good look:
It has six huge video SIMMs, one RAMDAC chip + one VLSI ASIC chip per color channel (?) and even an Intel 80860 CPU, for 3D acceleration. The price for this cool graphics board used to be around $12,000 (back in '92).

The amount of installed memory has changed since I captured that boot log. In the end of 2003 around Christmas time I bought some more RAM for this system, so I could fill it up to maximum. Hereby the "circle is closed". It's the best equipped, top-of-the-line DECstation system I could possibly have (without taking such special tricks like TurboChannel Extension option into consideration). This box has more than 10 times more RAM than most High-End workstation systems had at that time (1993) and it also has a very advanced 3D accelerator taking the time frame into consideration. In other words; Cool!
