It really does not matter ultimately. Ceramic is usually the preferred choice for high performance applications because they are solid state, long life, and have a very low ESR and ESL. Tantalum and electrolytics are polarised because of their construction, it is a limitation more than it is a...

Go for it!

Ceramic capacitor have a lot of advantage since they are entirely solid, they tend to cost quite a bit more than tantalum and electrolytics, especially when you start to go above 10µF. One trick that I use often is to parallel them (10+10 = 20, close enough to 22µF), which helps you buying less...

Markings are genuine, they look good

On my HP DDS DAT the plastic of the spindles has split and they pop out since there's a spring under them.

A celebration of the 68040 with one of my favourite chip from my collection

Actually it's the opposite of oddball because it's a JEDEC standard. 5V DIMM were relatively short lived, not widespread in PCs, and quickly eclipsed by SDRAM, so today they are not common, especially the server variety with parity.

Here's a quick note with the module bus width. Provision for double parity exist in the JEDEC standard and is mostly used by IBM, they are rare but they do exist. Any modules that will have a different number than 2, 4, 8 16, 32 memory chips on them will have a good chance to have parity...

The 85C30 is a dual interface chip. The best way to do it is to grab some samples from different sources and see what you get before ordering a larger quantity (should you need more). I can't think of any use of the 85C80 outside of macs, but it should still be a standard part from the AMD catalog.

I have decaped the 85C80 and you can clearly see some small logic of the 53C80 and the two SCC 85C30 on the die :)

The ARM710 I ordered straight from the website and they were brand new in trays, but the ARM60 were "sorry we don't hold stock". This is when they ask the actual seller that listed them. I had good hope with the ARM710 as this is not something in high demand at all, so there's no incentive to...

M Yes, more than a storefront, as the parts are actually inspected and going through UTSource physically, but you got the idea.

I have purchased some ARM710 from UTSource, they came new and top notch. The important thing to know about them is that they don't have stock, they are a broker that list stock from various (mostly chinese) sellers, and your mileage may vary. Some parts they claim to have are not in stock, you...

I own these two cards... would this be the holly grail?
