Baby AT tower I accepted this computer as a trade-in a few years ago. At the time, it housed an PC Chips M571LMR socket 7 motherboard, with a Pentium 200MHz cpu. Everything was bought brand new and installed by the guy who traded it in (on a PIII I sold him). I still have that board,now equipped with an AMD K6-2 380MHz . There are even fanclubs for the M571, just type into your favorite search engine and go.Maybe I'll make a page for that system, in the future. Later, I found a Soyo M6KL Baby AT size (Pentium II) motherboard on eBay. If I could have found a socket 370 in a Baby AT size, I would have bid on it. Specs: Baby AT tower (13" high, 7" wide, 17" deep) with a Star 230 watt power supply, Soyo M6KL 'Baby AT' slot 1 motherboard, Celeron 466MHz in a Soltek 'slotket' slot 1 to ppga 370 converter, 3 - 64MB strips of PC 100 RAM = 192MB (IBM branded, Hyundai chips), Fujitsu 10GB (boot), Quantum Bigfoot 8GB (storage), Philips PCRW 804 CDRW, 1.44 floppy, Diamond Multimedia (nVidia) TNT Riva 16MB AGP2x video card, Sound Blaster 16 ISA sound card (now called Vibra 16), and a 3Com 3C509b 'Combo" ISA 10MB Network card. It still says 'pentium' since we don't have a celeron badge. The real nostalgia here is the lighted display with the CPU speed (466). Way back when, oh say 1998, when I messed up my first computer (IBM ps2 model 70) I had to download a file from IBM.com. I had never been online before then, so I had to go to an 'internet cafe' about 10 miles away. The 'cafe' was a computer repair shop that had broadband connection. Their computers had a lighted CPU speed displays(at the time they used 166 cpus), like this tower, so it is a very nostalgic experience to own one of these 'historic' towers. Note my first cd burner, the Philips PCRW 804. AT power supplies had a 'pass-through' plug in for powering your monitor(left), and the cord (right) could possibly be used as an 'extension cord' by the looks of it.(Never thought of that before!) This board comes equipped with both an AT (with orange wires) and an ATX style power connector(20 pin box, center), so you can see the different style of plugs used. AT usually had a two part plug, with a single row of pins while ATX are usually a double row of 10 pins solid one piece connector. The curious thing about AT power supplies is that they do not have the 'soft' power-off buttons that ATX have, so instead of powering down your computer, you instead received a screen like the one at right. Then you pushed the power button off. AT also have a different style of keyboard connector (upper left,at left) than the common PS2 or USB plugs we use today. You would also need a serial mouse, that is a mouse with a 9 pin serial port connector, instead of the PS2 or USB . The later AT boards would feature 'pin-outs' and ribbon cables to add USB, PS2 mouse, etc. It made the inside of your computer a rats nest of wires, with little airflow. At right is a picture of 'my' AT to PS2 converter plug (probably bought at Radio Shack). On an AT tower, you didn't remove just one side to access the internal parts - you removed the top. The 'top' was usually a 1-piece top and sides (pictured at left). At right you can see the 'mess' of wires common when using a 'Baby' tower. A full-sized tower would have more room. At top left you can see the 3 strips of PC100 RAM( with yellow stickers) next to two unused SIMM slots (white). At right is a better view of the internals, with the drive ribbons removed. At left you can see the Slotket convertor installed in the Slot 1 connector, and the cooling fan is actually from a socket 7 (pentium). We didn't have a socket 370 fan narrow enough to fit between the slotket and the AGP video card. It takes about 2 hours for the system to get too warm, and this is more a 'museum' piece than something we use . At right is a 'top' view of the Slotket, this one is a PPGA 66MHz bus speed only, so you cannot use a PIII . And to finish off we have a photo of the 'classic' Creative Sound Blaster 16 ISA and the 3Com 3C509b Combo NIC on the left, and at right a 'top' view of the Quantum Bigfoot hard disk. Note: The empty slot in the back was for a USB connector. We used it for another project. Return to the Top of the Page Close
