To archive my Windows 98SE installation, I need an archiver that can -deal with long file names -compress/expand to long paths (>127 chars) without failing -can archive/restore files that have hidden, system and/or r/o flag -be used from DOS (7.1) Does such a program exist?

I'd advise agains LS chip as delay lines. The H->L transition is much faster for TTL tech than L->H. HCT is much more uniform, better idea I think. As the signal gets double inverted each stage, wouldn't this even out? For the 74LS14 the delay seems not to be very specific? Its between 5 and 22 ns …

These delay line chip actually seem 74LS14 with some pins snipped off, "repackaged" and sold for much more money. 74LS14 are Schmitt triggers which have a delay of typically ~15ns, 6 cascaded of them make the ~100ns you want here. The small tolerances do not really matter for the creation of the …

I use Fujitsu 15k U320 drives. Fast and quiet. The 1542CF (when flashed with the latest BIOS) supports 8GB. If you use larger drives, it just truncates to 8GB. As 8GB drives are old and slow, my 486 has got two 73GB Fujitsu drives, using only 8GB of each. As these server-grade drives are priced …

This issue is almost always caused by improper/insufficient grounding. It is just impossible to give advice without knowing the electric earthing system in effect. I suppose you have a TN-C system, as I have. With bridges between N and PE in the wall outlets. You can set up a small TN-C-S subnet by …

Wow thanks so much for the info. I’ll purchase the card and give it a go. Do you think it would be ok to power the drive before I get the controller to see if it spins up. I heard these drives are very fragile Yup, and they sometimes like to stick the heads on the surface sometimes. If it does not …

U58#5 went to 4.74V? That's pretty much VCC level, shouldn't be possible for a TTL chip, there's something wrong with U58 and that particular signal. Almost looks like it's somehow shorted internally on this particular data line. ... diagram of the internal structure for the LS 245. page 9 here: …

Cheapo stuff was and is always good for surprises. Don't worry about that little bit of flexing, as there are no flexing-sensitive BGA.

This is common with bad or cheapo electric installations. With a good electric installation such normally does not happen. To make sure you are not in danger of fire or electrocution, I'd suggest you to ask some knowledgeable friend or an electric contractor to check your electric installation for …

There exist L&C power supplies that are not bad. If you are lucky this is one of them. Maybe take some pics and post them in the thread "A tale of two PSUs", to let others judge.

This JTS "CHAMP" hard drive gives me an even more uncanny feeling than the L&C power supply. The design was done by infamous Kalok. Never seen a working drive of this brand. Does the drive actually sound "Kaaaaaa-looooookkkk" as some people suggested back then?

What confuses me much is when people mix mAh and mA. The first one is battery capacity (milliamperes/hour, 1000mAh indicates it can deliver 50mA over 20 hours). The second one is just how much current a power supply can deliver. Without having seen the phone and the power supplies/chargers, I still …

Most people don't do this, but it is useful: use the lastdrive=z option together with the MSCDEX /L:n option, using another than the default drive letter This way you can use the DOS CD driver and the Windows driver concurrently, with Joliet long filename support.

I have a similar problem. On my retro 486 Win98SE first complained that it wants at least 16MB RAM to install. Then, after putting in 16MB, it complained it wants at least a 66MHz processor. That sucks... I think I have sometimes heard people talk about a "Wintel cartel" extorting people to buy …

What about cards such as video cards that have fans built on them? At these low voltages nearby fans' inductive "input" can have noticeable effects. On graphics cards there is usually a metallic cooler that shields the GPU. Anyway, I don't think that sandwiched fans are particularly effective. So …
