its for a BOOT rom. it lets you boot a OS over the network. I've ever only used something similar once.

Novell netware computing for instance, or some sort of network based system recovery.
Had this explained to me, back in the mid. 90's. Never used or seen it in action though.

So module will speed up os boot time?

No, only allow boot from network (you need to setup bootp server somewhere in your local network).
Usually this need only for diskless workstation.
ROM module ik ok, but you need to flash firmware to rom chip, before inserting rom to nic. And i don't know is 3com boot firmware available now.

Something like that, yes. I have burned one or two eproms, back in the 90's when I studied computer science.
Don't ask me why I quit. So many problems with the boss I had, when I was trying to study as an apprentice.

I just barely remember us, creating a network bridge for the department at school.
Using two 3-Com netcards and a 486 motherboard. We had to flash the roms with custom software and
mount them in sockets on the cards. I was more interrested in this spikey thing going into that thick yellow cable.
Did not understand the technology, did not care. (the boss was an "it-dyslexic" asshole)

Only had a blast setting stuff up. And 6 months later, I quit my appreticeship, because I failed tests because of
no training at all in all fields. We were told that training for tests at the school was not his problem.
And we had to learn all on our self in our sparetime. Well... Things sometimes turn out this way.

Your thrift store owns.

Indeed it was!

$90 for the whole setup, but the DVD drive supposedly had issues. I had to pass on it, because the AT&T had hit/exceeded my planned spending budget that day. :p

90$?!?!?!? Holy fuck that's INSANE. Who would pay prices like that?

Sad thing is, it's probably still cheaper than what those systems go for on places like eBay nowadays.

Also, I wish my local Goodwill got more computers in to sell. The only two I remember seeing was a Q6600-based Gateway system that I bought for $12.99 and found that it needed a new PSU, in addition to a collection of vintage parts including a 386 mobo with processor (technically not a full system but it still counts in my book), all sitting in a box. I had to pass on the 386 stuff since the mobo looked to be suffering from battery corrosion, and it appeared you couldn't buy any of the other parts separate from the box. By the way, I later gave the Gateway I bought to my dad to use as his main rig, since he had been looking for a system for some time to replace his horribly aging P4-based IBM ThinkCentre.

I've gotten really lucky at that specific Goodwill store, but otherwise a majority of the computers they have are typical P3 and newer systems, accessories and whatnot. They also have other electronics, such as stereo equipment (Friend of mine found a new-in-box but admittedly older Pioneer receiver for $30 a while back), the occasional LaserDisc player, and video game stuff. I mostly go there hoping to find vintage computer stuff though!

Thrift store 1e. One of the many versions of the ALS100. Interesting to hear what it sounds like.

Babies arrived
CT3670
CT3620
CT3990

They are in working order but both apart from 3670 are in poor condition and need maintenance. I have to remove rust, oxides and sulfides from electric contacts and for providing protection against corrosion. I must prevent from non-obstructed electricity flow especially in the case of oxidized or worn contacts, I will use Kontakt S, this can be used in audio products -high and low-frequency, electronic industry and in other places where clean contacts are required.
Need to dry it properly and start testing this Sound Blaster AWE audio components.

That's sound logic to me. The card I consider will be used only for independed home purposes. Boot rom will be not needed. Thanks anyway for right pointing

Full duplex and coax, can you write some more about it?
i think I will use this one:

RJ45 will be more useful nowadays.
Do you know for what operations will be useful to use aditional ROM?

When we talk about coax ethernet, we're usually talking about 10Base2, which is what the BNC connector on that card is for. It only and always runs @ 10Mbps in half-duplex. This means a NIC sends and receives on the same signal lines. Therefore, it can only send OR receive at any one time, otherwise a "collision" occurs and the data sender must retransmit.

The RJ45 port on the 3c509b is typically more convenient today because it can be used with common 10/100/1000 autosensing switches. On this particular card, that RJ45 is a 10BaseT port. This means it runs @ 10Mbps over common twisted pair cabling (standard ethernet cabling). The card can run either half-duplex (most common mode) or in full-duplex (rare). In full-duplex, the pins on the RJ-45 that are usually used for collision detection in half-duplex mode are instead used as dedicated transmission pins. Along with the original data lines, this allows for dedicated separate and simultaneous RX and TX lines (hence, full-duplex). However, to use full-duplex with this card, you'd need a switch capable of manually setting the switch port to 10/Full because the card will only ever auto-negotiate to 10/Half.

For all practical purposes with common equipment, this is a 10/Half card. If you have a fancy managed switch that allows you to force a port and "nail" it to 10/Full, then you could take advantage of 10/Full. I myself have only done this once, just to prove it was possible. Otherwise, it's a pain in the rear.

A lot of high-end motherboards today do have this functionality (network boot) built-in. It's called PXE. Servers almost always have it. Back in the day it was optional and different Network OS's had different boot rom's available for you to burn to an EPROM and install yourself.

A free CRT I've got - Philips Brilliance 107P4.
Nice colors,and it's got an amazing HD resolution - 1920x1440. (the monitor's native resolution)
I know it doesn't look in a pretty condition,but as long as it works it's fine for me.

At a decent refresh rate? The 201P I had barely managed 75Hz or so at that resolution.

Thanks QBiN for useful networking informations. I always use RJ-45 and didn't know much about PXE or boot ROM, never use of server operating system depends workstation or equivalent solutions. This card will be use in Win95 home machine for Quake LAN experience, I hope there will be no troubleshooting with other Win98 machines

Gigabyte GA-7N400 Pro2 v2.0 Motherboard. nForce2 Ultra-400 chipset, with the dual-port IDE RAID onboard, and SATA RAID onboard. Snagged it for $16.22 + free shipping, comes with (unknown) CPU and heatsink. Seller claims it works, was pulled from working machine so I'm hoping it does. Seller's pictures are used here. I think these are the latest and highest-end motherboards for Socket-A. I bought it personally because back when Socket-A came out, this was one of those setups that I saw on the display wall at my local Fry's years ago and dreamed of owning, but never did get to because they were like in the $250 region new and I never could afford one. And then as time went on, eventually they were discontinued, and then eventually we couldn't even find em used, at least not at decent prices. Traditionally they've been in the $150+ range for nice boards like this even used. So.. this was sort of an impulse buy.

It's a Luxman L-3, 42W per channel.

Apparently it was worth over US$300 in 1978 when it was new, which is over a grand in today's dollars.

And to think dad was just going to send it to the dump!

Edit: Apparently Luxman is still around, and still manufacture high-end gear. Neat.

I saw an IMac G3 with the colored case at the thrift store for $60 about a week or so ago.
I would have bought it from half that but not for 60 bucks. Apparently someone DID buy it
(despite the eBay BIN prices, I can't justify that price)
