IIRC, AV70-1 is a ICS chip. full part number is AV9170-01CS08. It's a clock delay or clock synchronization chip. ICS = Integrated Circuit Systems IIRC, the chip takes a clock input and outputs the same clock, except.... It also takes a second clock input and it aligns the phase of the...

I was browsing the items from Memory Master and they have a bunch of the PM6100/7100 ROM modules for about $13. https://www.ebay.com/itm/175602575946?epid=1228687524 Posting in case there are folks with a machine where the ROM was pulled. That's the 341-0741. I think it will also work in...

I've used SoftRAID with the VST UltraTek/66 (ATA-66) which used Firmtek firmware (same as Sonnet's cards) and I've also used it with the Acard AEC-6280M, (Acard firmware) which is an ATA-133 card. Another option is to get an Acard AEC-6880M which is a hardware RAID (0, 1) ATA-133 card. I...

It's (the PS) is probably a one layer board. I would trace out a schematic and from that it should become fairly obvious what role that component was playing. Power supplies are not all that complicated. I'm a little curious about calling D1 a *bridge* rectifier. A bridge rectifier...

My ancient (wetware) memory says that when the NuBus G3 upgrades came out, the SEIV was the only SCSI card compatible with them. NewerTech was the only seller for a long while. Later they got it working with the JackHammer as well. If my memory is accurate, then you shouldn't be having the...

The details are lost to memory, but there was a specific NEC USB chip and a specific TI (?) chip recommended for Firewire in PCI PowerMacs, way back in the day. I'm sure it's posted about somewhere in the annals of Mac discussion... I think NEC D720101GJ was the recommended USB chip back when...

I haven't looked in probably a couple of years, but the last time I visited, the local Goodwill Computer Store had several 1st Gen. AppleTVs for about $10 - $15.

I liked Pathways more. There's more of Marathon, but I just gave up on one level where one had to do some kind of grenade jump out of lava to progress in the game. I liked the puzzles in Pathways. But for multiplayer, of course, one needs Marathon. We used to have annual Marathon LAN...

Try washing the board thoroughly, probably with 91%+ isopropyl alcohol. The caps may have leaked enough goo to cause a short somewhere or may have eaten a trace. If the former, while the caps still need replacing, washing the board may get you to a workable state for testing. If the latter...

IIRC, the VHDL text book my class used way back when contained the VHDL code for a 6502 in the back as an appendix. Of course, that would be for FPGAs, but thought I'd mention it. Later Edit: 6805, not 6502. So completely irrelevant. Sorry.

It looks to me like a short occurred internally in the chip and melted the plastic from hte inside. One of those discolored leads goes to what is almost certainly a bypass capacitor, so that's probably a power pin and one of the other pins is on an extremely short lead and looks like it may be...

Am I correct in observing that it no longer is available from Amazon? Or the manufacturer either, I guess. I guess I should have acted two years ago, but I wouldn't have used it yet, so kind of a silly purchase, until it turns out that was the one opportunity in time to get some...

Well, when you partition the drive, you could create an extra one for OSX...

For even more fun, OSX on the D630... https://osxlatitude.com/forums/topic/8081-full-chameleonenoch-packs-for-d620d630-snow-leopard-lion-mountain-lion-mavericks-yosemite-el-capitan-sierra-high-sierra/

I love the optional modifications. Very thoughtful and sensible.

I don't remember what the machine uses and am too lazy to look it up, but... If it uses a 2.5" SATA drive you should certainly be able to replace it with a SATA SSD. If it uses a PATA drive, you can get a PATA => MSATA adapter for about $15 and install a somewhat more expensive MSATA SSD...

Thank you. Yes, on my E6410 they were also socketed. But on the D430 which is a family relation to the D630, the CPU is soldered. Probably because the D430 was very compact for its day. I feel like the D series was a high point for the Latitudes. Not the pinnacle, because Latitude has...

We're the CPUs socketed on those laptops?

Bottom port is for D series docking stations. The docking stations were great if you needed to move your laptop often between stations with local monitors and keyboards. It can also provide serial and parallel ports, which can be handy if you want to drive an old chip programmer, for...
