ZEOS Cobra motherboard
As you can see from the specs, a nice board, but it only works at the speed of the clock crystal soldered on to the PC board, in my case at 60 Mhz. Otherwise a real quality board, if dated (it uses the mercury chip set)!
| Length of add in slots are very important because some add in cards are so long that you can't fit them into your computer. All motherboard manufactures should include this information on their pages. Since they don't users like you and me will have to provide the values. These sizes are measured from the point that the back edge of the add in card fits into (AKA the metal slot cover), to the first obstruction on the board. BTW I define full length as a slot that is not obstructed by anything on the motherboard. Other obstructions in your case may limit the size of add in cards, severely if you don't have a tower. Some other facts: 16 bit ISA slots are 16.5 cm long. PCI slots are all 13 long. All cards of those lengths and shorter will fit in any motherboard that has an empty slot. Uncomfortable with centimeters? So am I, but I am working to change that. Just remember, there are 2.54 centimeters in an inch, if you need to convert these numbers. (You already knew that, right? :-) |
- There is no way to turn off the all OK beep heard every time the computer reboots, short of disconnecting the PC speaker.
- When floppy check (which takes forever) is disabled, you can not boot from a floppy, no matter what the boot order is set to.
- When rebooting, there is at least a 3 second delay between the [ctrl][alt][del] combo, and the clearing of the screen. My old 386 could do it instantly, why can't my Pentium? On the other hand I reboot much less than I did in those days.
- No turbo switch! Geez, would it hurt that much to include one? This is Intel's fault, the PCIsets do not support turbo.
REVIEW: USR Sportster 28.8/33.6
REVIEW: Sony GDM 17SE1
- The monitor has to warm up before the picture quality gets reasonable. The lower right hand corner of the screen gets a strong reddish glow when the tube is first turned on. After a few minutes the glow completely subsides.
- While the monitor has convergence controls, the convergence changes notably from when it is first turned on, to about 30 minutes after that time, lowering the picture quality even more for a short period of time. Of course if you never turn your computer off you will never see this problem. As it is, you can just set it to the best setting for warmed up mode, and endure the convergence problems when it first starts up.
- Video adjustment controls are hard to use and are poorly labeled.
REVIEW: Microsoft Mouse 2.0
Everybody has seen one of these, it's the large "ergonomic" mouse made by MicroSoft. It has two flaws:
- It has only two buttons,
- Its mouse driver takes up more memory than any other mouse driver I have seen. On the other hand, all the smaller mouse drivers will crash one or more DOS programs I have, so all that extra memory must be doing something.
