64kb of cache in a 386 was high. The A series of IBM model 80's got this treatment. From ZERO to 64kb. From IBM. Cache ram was EXPENSIVE AS FUDGE back 'in the day'. Don't expect cache on a 386 until 33 & 40 mhz. Even then, don't expect a lot of it.

Found a few boxes of disks at a thrift store. 2 new packs, one used. Had to break out the eraser and save an old couple from identity theft. There was also 2 disks of images from a Sony Mavica of said old couple... Well, let's just say, I wish that tape eraser worked on brain cells. http://i.imgur. …

I REALLY like the IBM PS/2 line of computers. It's a damn shame MCA wasn't more popular and subsequently cheaper to acquire cards for.

Well, I just spent $100 on this: I didn't have that monitor, I needed the floppy drive and everything else was just icing on the cake! Yay! Now I don't have grocery money for next month!

oh don't be silly. If the board is having cap issues, instead of replacing ONE OR TWO just do them all. Why is this such a foreign concept? the LCR meter I bought is going to be mostly used for fixing old power supplies. Checking power trannies/mosfets & diodes. Caps generally are too cheap to frack …

WTF is wrong with you people? "Sampling" caps to judge if there might be bad ones is probably about the dumbest thing I have read in awhile. This is not QC for a cap manufacturer, this is about repair and maintenance. If you already desolder caps anyway, just recap the whole thing and be done with …

Not the sort of maintenance strategy that will fly with anything having expensive downtime or repair cost. Sure, your car tires will tend to wear fairly evenly (unless your front alignment is bad or the weight distribution is uneven). That won't always be the case, and you should never assume so. …

get a roll of the old lead type solder. Flow a bit onto each joint. remove cap, then remove solder via pump or braid.

All the electrolytics, yes. All told, 20 caps? You will get faster, the more you do it. I did my first recap so many years ago. It looked horrible. I'll post the pic later. Just get a decent iron and a bit of desoldering braid and with practice, it goes quick. I even ENJOY doing it. I like to work …
