You can normally find the datasheets for most capacitors, and work out the correct ESR/ripple current from that. Then cross-reference it to a different series to find a suitable replacement capacitor. Normally, exact ESR isn't terribly important, because electrolytic capacitors have pretty large …

Just force the connector on, normally with a little force you can punch right through the blocked off pin on the cable. It is what I normally do. Please don't do this. If you are in the situation ultra code mentioned, use a small drill bit to make the hole. its not a disaster if you frack up a …

Still need to wait on some "new" 34-pin floppy cables to hook up a Gotek floppy emulator to update the BIOS, because I am out of floppy cables that accept all 34 pins, and therefore are compatible with the Gotek emulator (I mean, I'm sure I could "mod" it and snip off a pin off the emulator to fit …

I would guess you will have a harder time finding a working AGP gamer video card then you will finding a working IDE or SATA hard disk drive in the future. Todays spinning disks will also probably outlast current SSD drives. I disagree. SSDs could easily last 50 years. I have had only a single SSD …

SATA will still be around for another 10 years. There is no replacement on the horizon for standard spinning hard drives, which enterprise just uses heaps of.

Different size caps can affect the ESR, ripple current handling, reliability and cost of a capacitor. Making a capacitor smaller for a given voltage/capacity tends to negatively affect at least one of the 4 above factors.

in Milliways

Pure software emulation can be repeatedly nested until you run out of performance. You can nest bochs within itself. Virtualbox in some configurations can probably work fine this way too. Emulation that relies on virtualization features of the CPU will not work this way. For example, it would not be …

How about ISDN adapters ? ;-) Wouldn't hurt to keep 1, maybe 2. But unfortunately, this kind of network hardware that relies on 3rd party networking systems is kind a useless. Keeping a set of token ring cards with suitable switch and cables can be fun because you can use and demonstrate them. …

There is little point in keeping any POTS Modems in my opinion. In my area at least, POTS doesn't exist so they are kind of impossible to use. Maybe keep a couple, but beyond that, toss the rest IMO.

The i740 was the card I got after the s3 virge. It was still heaps better than the S3 virge. i740 is around the same performance as the riva 128. Good for a nostalgic lark, but plenty of better cards for cheaper for building a retro rig. I did get one for my retro rig, but I decided in the end that …
