The old baby has gone through 6 years of changes to the point where the only original components left are the case, floppy drive, and tape backup. Note that this is the same full tower case (except the one pictured is the AT version) used for the server in SACMDA's CNS Lab 2. 

This one started out back in 1996 with a Pentium 200Mhz CPU and 64Mb of 72-pin EDO SIMMs. It had two 3.1Gb WD hard drives, a 24x CD-ROM, Diamond Stealth 3400 4Mb video card, SoundBlaster sound card, US Robotics 33.6K data/FAX/voice modem, Adaptec SCSI card, and a Seagate 3.2Gb Travan tape backup along with the other standard accoutrements.  The system was rounded out with an HP ScanJet 4p, HP LaserJet 5L, and HP DeskJet 870Cse. It triple booted to Windows '95 and Windows 3.11/MS-DOS.

In 1997, it went to a Pentium 233MHz MMX CPU and 128Mb of 72-pin EDO SIMMs. A 6.2Gb WD hard drive was also added. A Diamond SupraExpress 56iSP 56K FLEX/V.90 data/FAX/modem card replaced the old one. A Diamond Supra video camera with internal video capture card and 2 Gravis Pro gamepads entered the picture.

Along the way from 1998 through 1999, it got keyboard, mouse, and monitor upgrades to the present Logitech iTouch keyboard, Logitech WheelMouse, and Philips 107s 17" monitor. A Voodoo3 2000 16Mb video card was dropped in and the two 3.1Gb hard drives were replaced with a WD 7200 27.3Gb hard drive. The CD-ROM went to an AOpen 48x drive, and an HP CD-RW 8250i 4x4x24x drive was added.  It also got a new beefed-up 300W power supply to run it all. Windows '98 and then '98 SE became the standard OS. A Casio QV-300 Digital Camera was added to the peripheral repertoire.

Changes/Upgrades in 2000:

• Replaced old PCChips motherboard with a Tyan S1590S Trinity 100 baby AT -- 66/100MHz FSB, Socket 7, VIA Apollo  MVP3 chipset, 1MB L2 cache, 4 PCI, 4 ISA, 1 AGP 2x, 3 168-pin DIMM up to PC-100 SDRAM, 2 72-pin SIMM, UDMA ATA/33 EIDE (see info below)
• Replaced Pentium 233 MMX CPU with an AMD K6-2 450MHz (see info below)
• Replaced old 66MHz EDO SIMMs with a 128 MB Kingston PC-100 CL2 SDRAM DIMM (see info below) -- now 512Mb of Kingston PC-100 SDRAM
• Replaced the video card with an ATI XPert 2000 32Mb card
• Ditched the 5.25" floppy drive (antique)
• Added a Macronix 10/100 Fast Ethernet NIC
• WD 27.3Gb drive moved to new dual PIII PC and replaced with Western Digital Caviar 15.3Gb hard drive
• HP CD-RW drive moved to new dual PIII PC
• Printers, scanner, and Casio camera moved to new system
• OS ended up with Windows Me
• Major applications reverted to MS Office '97 Pro, Corel WordPerfect Office 8, and CorelDRAW 8 Graphics Suite

That's "Monk" perched atop the monitor...  :)

The Tyan Trinity 100AT (S1590S) is a good solid workhorse board that supports a lot of newer as well as older technologies. It's a very nice AT/ATX transitional board with some features of both form factors. Match it with an AMD K6-2 450 CPU and a good quality 128MB PC-100 SDRAM DIMM and you have an outstanding, inexpensive computer base to build from for around $180 (board, CPU, and memory at today's prices) if you shop around for best prices. It is also compatible with Windows '98 SE, Windows Me, Windows NT 4.0 SP6, and Windows 2000 (I've loaded and run all four on it with no problems). I'd rate this board * * * * for price versus flexibility and capability -- good for upgrading old AT systems. This little baby really cooks running a 100MHz memory bus with 128MB of SDRAM and the full 450MHz CPU speed! It's the same clock speed with 4 times the memory of the workstations in the CNS Network Lab 2 and costs considerably less. Since the board also has a 5x clock multiplier, you could probably run a K6-2 500 in it as well, although Tyan doesn't list it as an option. Add an extra cooling fan or two in the case!
