Re: Recapping motherboards - no non-low-ESR caps existing (anymore?)

The range of viable cap esr value depends on the design of the regulator feedback loop and the response characteristics of the regulator itself. https://www.ti.com/lit/an/slva115a/slva115a.pdf https://www.vogons.org/viewtopic.php?p=1147493#p1147493 https://www.vogons.org/download/file.php?id=159502 …

Re: Any love for AM2?
Posted on 2023-02-27, 01:30
The worst thing about AMD chipsets for AM2, I think it was the south bridge, the SATA interface always seemed slower to me than Intel chipsets, making the whole system seem slower, at the time the only solution I found was to use RAID 0 until SSDs became common and "affordable". But it didn't …

Hi, I succeed to make a simple IOCS16# decoder using 2 log. gates IOs 7432 and 7403 (simple grounding of IOCS16# is no go as only data register requires 16-bit access and other regs. needs 8-bit). Now the SSD is identified properly and works fine on that ancient 386 with XTIDE BIOS. I plan to make …

Unpowering a chip never works, it will then start powering itself up through all the other connected pins and this will lead to excess distortion etc. You really do need to remove a chip or utilize some actual disable feature when present. Even worse, I bet the behaviour is quite difficult to …

This card has few issues : * no way to bypass the speaker amp so it will be too loud and also quite noisy because of it * no proper voltage regulator for analog side, only a zener based shunt so expect digital noises etc. in the output. There is a spot for a 7805 and this can fix at least this …

Yep, everything works fine with VLANs. I've had a "retro zone" as elvis explains for many years now, historically with a physical Windows Server 2003 R2 machine hosting everything, and now virtual on a TrueNAS SCALE host. I've been kicking the tires though on RetroNAS, and EtherDFS is definitely …

Oh, I just realized that it's an overdrive. Not sure about all the test registers in that case. Clueless1 has (or had) a P55 based POD. Full TR12 register support. I think we tried to say the same thing but you misinterpreted me. Definitely possible. In general, I've found PMMX CPUs to be capable …

Early games aren’t throttled but pentoum 200 is probably already too fast for those. There is a lot that a p3 500 can do. Not much that a 200 can do that it can’t (other than being cooler. ;) Disagree. Katmai has a massive performance gap when disabling caches. Games like Commanche and U7 really …

D'oh! I mean, asking for a friend : what does managing old computers inside modern networks involve? Future plans are to use RetroNAS as a firewall of sorts. The current idea is: RetroNAS will run dnsmasq (small DNS/DHCP tool) on the device itself, to configure all IP level stuff into a separate …
Re: Socket 7 build, which direction should I go?

I actually don't have any great data on that -- mostly on FSB manipulation. I should take my P55 time machine off the shelf and do some testing with multipliers.

A nice modification is two switches for FSB/multi reclocking. One toggle on JP5B to go from 50 to 66 mhz FSB (switches to 1-2 common from 3-2 common), another toggle on JP7A to switch 3-2 common to 1-2 common again. This gives you 100 mhz, 133 mhz, 175 mhz, and 233 mhz. On top of that, you get all …
