What were your latency timings?

Re: Pci ata133 worth it?
Posted on 2017-02-10, 01:12
Running higher performance RAM can make sense as it allows you to use more aggressive timings even if you're not increasing the RAM clock. ATA 133 doesn't confer those same advantages. It doesn't make an ATA 100 storage device faster or more stable.

You can always expand the drive after using GParted.

I think reverse engineering the VSA-100 would be very expensive. Does the Quark include legacy chipset functions like ISA with DMA? It's not intended for compatibility the same way that Vortex86 is.

The card is a Freetek Pro32 PNP. It has an ALS100 sound chip which provides SB/SB Pro/SB 16 compatibility as well as a Crystal/Dream 9233 chip (and associated ROM chip) for sample based MIDI synthesis. The 9233 is a fairly common solution for onboard MIDI synthesis, but there's certainly nothing …
Re: Packard Bell Pack Mate CPU upgrade?

For the video memory upgrade, you'll need two 256k word x 16 bit / word modules on ZIP packages. Check the chips on the motherboard to see what latency the upgrade modules will require. On the 420M motherboard for example, the on board module is an MT4C16257DJ-7 from Micron which operates at 70ns …

Sure, people are free to speculate, but holding out for an outrageous price is seldom profitable.

You can always set your max price and use auto bidding. Manual bid sniping isn't really a thing anymore.
Re: Which ISA Disk Controller Card to Use?

You may want to test if any of the controllers provide a 16550A UART as it's a nice to have feature for high speed serial transfers.

With CF cards, you also have to be careful of the removable bit. Not an issue with DOS or Linux, but it can be an issue with Windows. Change old low HDD to a CF card? http://www.thinkwiki.org/wiki/CompactFlash_boot_drive

That's the linear regulator that drops the 5V down to whatever the CPU needs, like e.g. 3V. It's most likely an LT1084: http://cds.linear.com/docs/en/datasheet/108345fh.pdf It needs a big heatsink because it converts the voltage difference (VxI) into heat. Measure the resistance from pin 1 (the one …
Re: Crazy Idea - MT32 WaveBlaster Card

It's true, for 5v -> 3.3v a resistor network would be fine; but I need to go 3.3v -> 5v as well, so I think I will need at least one active chip to perform that task, and if I've got one chip to go one direction I might as well have an active chip to go the other direction. The buffer chips are …

Perhaps the requisite supply voltage could be leached from the signal lines prior to the ladder pack? The additional current required would have to be minuscule, but I think it's possible.

When I think of Windows XP, my inner voice is telling me to go dual core. Instead, I like socket A for a monster Win98 build. Along this route, Vortex 2 card sound can be an option. If you definitely want to use XP, Aureal cards should generally be avoided due to the termination of vendor driver …
