Folks, Today I discovered I had more RM Nimbus machines than I actually need, as well as a few Acorn Archimedes. Any interest? The RMs are mostly PC-1 which is a pretty well specced 80186-based machine but there's also an AX/2, VX/2 and a microchannel M-series. Not strictly home based machines so I guess I should pass them onto someone! Cheers, -- adrian/witchy Owner of Binary Dinosaurs, the UK's biggest home? computer collection? www.binarydinosaurs.co.uk

OT: wireless access solutions

by brianlanning＠gmail.com

It appears as though my wireless router hub thingy has died. I need a new one. But here's the thing. I wan't to setup a smoothwall machine using some old hardware I have around. And since I'll have this, I don't need (or want) the router feature that's seems to be supplied with all these consumer grade wireless access points. What I really want is a wireless access point that simply puts everyone on the wired network, if that's possible. Ideally, I'd like to handle DHCP through the smoothwall box, although I'm willing to do static IP on the wireless devices if i need to. Worst case, I guess I could just continue the way I always have, having the wireless access point handle DHCP for the wireless devices and turning off the firewall features so that everything passes through. Of course, maybe I want that extra layer of security since WEP is so bad. But I know there's new wireless security standards tor replace WEP. Can I get away with just a wireless network board in the smoothwall machine and use that as the access point? I suspect range would suffer. As you can tell, I'm not up on any of this. I know enough to assemble a network that works. But network design and security isn't my thing. brian

Wood thread trick

by wdonzelli＠gmail.com

It is amazing how many people MISSED THE DAMN POINT. The original posted "trick" involves a situation where there are *no* threads left in the wood. By backing the screw out with a little pressure, eventually the wood will give at the point where the original threads were, due to how the fibers of the wood remain (not crushed, but cut). All this happens at a scale pretty much too small for the unaided eye. MInd you, the new wood screw will hold, but not well, because there just is not much good fiber left. This trick does not really work with metal - no fibers, obviously. This is *not* the same "everyone knows it" trick about backing out a screw to find the thread. -- Will

Switch cleaning

by rwadamson＠hotmail.com

I'm restoring a couple of RK05s which I haven't used for a few years. The rocker switches have lost their springiness and the contacts are a bit hit and miss. I don't really fancy trying any disassembly as I think this is likely to be fatal. Any recommendations for the best approach and materials (available in UK)? Thanks Bob

There are consumer devices that only act as access points, such as the Netgear WG602. It accepts DHCP from another device and lets wireless devices connect to your existing network. I've heard of some who take router-and-AP devices, assign them to your desired subnet and on a static IP outside of the range assigned by your actual router, turn off DHCP serving, and don't connect anything to the WAN port, just patch it to the LAN side, (using a cross-over if it wasn't auto-sensing.) http://kb.netgear.com/app/answers/detail/a_id/1080 http://www.dslreports.com/faq/11233 So yes, you could use a $35 WGR614 from Walmaret instead. - John

disk platter advertising

by dgriffi＠cs.csubak.edu

I found a fun little "business card" in the form of a 5.25" disk platter with a business name silk-screened on it.

DIP packages & the 555

by tshoppa＠wmata.com

My favorite use for the 555 that I ever saw, was in a homebrew paper tape reader in Byte or PE in the mid-70's. The timing function wasn't used at all; only the Schmitt trigger function used. Default 555 Schmitt trigger action is at 1/3Vcc and 2/3Vcc; just brilliant! Tim.
