This bunch of network cards... Nothing too interesting maybe beside the cabletron card - why does it have two AMD PCNet ISA+ chips and 4 LEDs? Also no BNC connector (but it has soldering fields for AUI connector which is not populated) and PLCC socket for bootrom... it has to be fairly recent card …

VIA VT6212L is Win98 compatible -- drivers are available for these cards (google "VIA USB 2.0 Host Controller Driver"). I have two of them removed from some PCs I bought and both were working under Win98 in these machines. Edit: http://download.viatech.com/DownloadDriverSvl?driver_id=2105

Hello. I already have a PCI Card installed in my system. It provides two USB2 Ports and two PS/2 Ports and runs well. I don't need the PS/2 ports. So I searched for a new card that has USB ports at the back and an internal header. I found one manufactured by Lindy. It arrived yesterday and seems to …

(...) CT1703-T is the noisy DAC appearing only the CT2230 (19413) and (29417) but not on the CT2290, also on the first revision AWE32 CT2760. CT1701 is the oldest and noisiest appearing on the first SB16 CT1740 cards. The early AWE32 CT2760 which came in 1994 use the noisy CT1703-T DAC. Later AWE32 …

Guys.... you are confusing Mbps with MB/s. 32-bit 33Mhz PCI is 133MB/s (1064Mbps). ISA is 133,28Mbps (16-bit * 8,33Mhz = 16-bit * 8,33M(times)ps = 133,28Mbps = 16,66MB/s) that's true (but now there is also a huge overhead because of how ISA bus is working - refer to vcfed thread mentioned above for …

Got this HP network adapter. I plan to upgrade my retro home network to 100VG-AnyLan standard which, for those who don't remember, was a failed 100MB LAN standard competing with what became the Fast Ethernet. As often, it was technically superior, but the market decided otherwise ... Am I the only …

Looks like a generic MDA / Hercules card with 512K of RAM on it. Looks like it's got a light pen and two joystick ports, too. The jumpers up top are probably for the joysticks, if I had to guess. Is that an bus mouse port at the bottom? But it's not. The switch on the bracket states 'Mono' in one …

Also this vendex card has some weird bodge on the backside and somebody tried to use it in 16-bit slot as you can see... I don't …

Why, AMD of course! Intel is so mainstream. K6-2+ is kind of niche. Also it's very overclock-able.

Unless you have a 8-bit XTA card which I'm not sure will even work on a 16-bit PC. XTA controllers do work in 16-bit ISA slot. I successfully ran such a thing in a 386. Any 8-bit ISA card will run in 16-bit slot, why wouldn't it? It HAS to. Because 16-bit slot is 8-bit slot with additional address, …

A friend of mine (who is also a fellow VOGONer BTW), has CT1600 which is in very nice visual condition (no scratches etc, other than two dented caps which shouldn't cause the described problem). A Unfortunatelly card is not detected by the system - like it's not there. We compared it against mine …

Thanks for this test. While we're at it, have you tested the CT1350B in a faster system than 16Mhz? Reason I'm asking is I have one in a 386DX40 - I get noticeable audio artifacts and wrong tones in some games when the system is running at full speed. If I de-turbo it or disable cache, the sound …

what was your hypothesis, I never owned a SB 2.0 but I read a lot opinions about them mostly negative, so I went ESS audiodrive for Sb 2.0 and never looked back. :happy: There was no hypothesis other than that later revision may be a bit less noisy (and now I know it's not true unfortunatelly).
