You still need a special cable to connect it to VGA, it's a stupid connector competitor to DVI that didn't catch on. This one specifically works for Voodoo 3 3500: https://www.ebay.ch/itm/282632475628

Its not a standard 3500 but rather a OEM DELL model, has totally different ports to the original 3500, mine has a normal VGA port on it rather than the port you describe. I would have loved a DVI port but alas you cant have everything and a 3500 without the obnoxious breakout dongle is already a nice thing.

Well what I see for that part number is...

Quick question for the Pentium 4 aficionados out there, looking at grabbing a Presshot 3.4 SL7PP to throw into the 875p board I got recently and was wondering if it would be better to stick with the 3.4 SL793 Northwood I already have?.

Reading around has them both pretty much on par till you overclock them at which point the Presscott overtakes the Northwood, also have others saying the Northwood I have is pretty much the best P4 ever made and everything after it was a mistake till Cedar Mill.

Cooling isn't an issue here but I do know the Presshots run hot along with the VRM getting a kick too.

Board if anyone is curious is https://theretroweb.com/motherboards/s/aopen-ax4c-max-ii so VRM wont be an issue.

Any thoughts ?

I suddenly remembered my Charlemagne Pentium 4 collecting knowledge

3.4Ghz 478 Northwood - will be a D1/M0 stepping = best Northwood 478 silicon (check for full rows of caps under the cpu)
3.4Ghz 478 Prescott - is just a normal Prescott with a higher multiplier although some boards might allow it to run at a lower multiplier

(3.4Ghz 478 EE - will be a M0 stepping = best Northwood 478 silicon with big cache)

Northwoods need premium silicon and a decent board to reach >3.4 Ghz (it was fun when overclocking 2.4Ghz t0 >3.2Ghz)
Run of the mill Prescotts can reach higher clocks in both 478 and 775 form

Northwoods 20 stage pipeline and smaller lower latency cache
Prescotts 31 stage pipeline and larger higher latency cache

Most retro games suitable for a Pentium 4 clock for clock will favour the Northwood.

Consider - FSB, Memory, PAT

*Edited*

Two ways to maximize P4 performance -

Small FSB overlock, high multipier, PAT still enabled, low latency DDR 400 2-2-2-5
High FSB overclock, low multiplier, PAT likely disabled, DDR500 3-3-2-8 or better

The former suits the high multiplier locked cpus like the 3.4Ghz Northwood
The later suits the low multiplier or unlocked cpus and will have greater memory bandwidth

One 875 selling point is PAT giving up to 10% performance increase
However it's important to realise if you overclock the FSB say over 215Mhz there are invisible straps where PAT becomes disabled depending on the bios

That AOpen is a nice premium board but not so focused for overclocking prowess as an Abit, Asus, DFI etc especially the memory voltage
So I would keep the 3.4Ghz Northwood with a small OC and tight timings, maybe one day look for an EE

If you had say an Asus/Abit 865/875 478 with lots of community vdroop and bios mods available then drop a 3.0 or lower Prescott (for lower multiplier) in for some fun and heat. Or just do it on a 775 board.

This (amongst 5 other S3 Trio64) appeared at my local second hand shop. I didn't buy it yet, but for 3€ I might buy this mighty AGP card 😉 It’s the first time I actually see one…strange that they branded is a Trio instead of Virge.

Ah I didn’t know there were custom 3500 cards, I guess the Dell one is even more desirable than the standard model then 😀

Yes a M1-DA or "EVC" connector. I have a cable (came with a Dell branded Radeon 7000 AGP) which should work if it does not have a DB 15 vga.
I ordered the card, they said they would email me back which connector type it has..has a 30 DOA return also.

At a glance I thought that sticker said AQUA rather than AQA and now I have Party Girl stuck in my head.

Bought this Packerd Bell Club 30 from EBay with a lot of ports even 2 USB exts and a new CD Driver of HP!!

The cool thing about it is that they are AT "compatible", the build quality is very good, and only requires a small modification to the 3pin connector (PS_ON#).

Another cool thing is that those PSUs have an ATX-like soft-off/standby, i.e. the power switch is not connected to mains making them very safe. Very well built units, and Astec normally uses all-Japanese caps.

hello is still avaible?

I got one like this, it starts and works

Ah, a nice Matrox Millenium

What motherboard is this ? Do you have a mix of EDO and SD-RAM? EIDT: Ha no I presume this is the L2 cache module ?

I think you are seeing the COAST module.

You are right, thank you. https://dosdays.co.uk/topics/coast.php

For the PC XT I found an interesting solution, for the video card, I have an 8-bit ISA, which should be a Hercules (or a monochrome one), the connector for the monitor is with 9 pins, unlike VGA monitors that have 15 pins, so to solve I had to find an 8-bit ISA VGA, or a monitor with 9 pin input, or a 9 to 15 pin adapter.

After various searches, I found a fairly inexpensive solution, a connection cable to the monitor, with VGA port on one side and 9-pin port on the other.

Just replace it with that of the monitor, which has two VGA input outputs, and connect the 9-pin to the Hercules ISA 8-bit, while the other goes to the VGA monitor.

How’s the image quality since it’s going from digital MDA/CGA to analog ?

I ordered the cable, it has yet to arrive, and then I have to see which monitor to use, because I don't think they're all right, maybe I'll have to look for more info on it.
I hope it arrives soon
