New *square* 1:1 26.5" LCD monitor 1920x1920

by swiftgriggs＠gmail.com

Does anyone have a EIZO FlexScan EV2730QFX-BK monitor? I currently own an NEC MultiSync 17" LCD that does sync-on-green and works with my SGIs and other older systems. However, I'd love something bigger. The problem is that when I use widescreen monitors on systems which cannot display widescreen resolutions, everything is pretty distorted. My guess is that, since this is a newer monitor, it's not going to support sync-on-green. I'd still be tempted to get one, simply because I've grown to dislike widescreen for productivity uses (they are great for entertainment). However, at over $1k, it'd definitely have to support my retro gear to make it worth it. Now that I look, it says it only supports displayport and dual-link DVI. That means I'd need a scan converter to use it with older gear. Ugh. Well, anyone go down this road already? -Swift Some links to this beastie: http://www.eizo.com/products/flexscan/ev2730q/ http://www.amazon.com/FlexScan-EV2730QFX-Monitor-1920x1920-EV2730QFX-BK/dp/… http://www.colorhq.com/Eizo-FlexScan-EV2730Q-26-5-LCD-Monitor-p/ev2730qfx-b…

Virtual Swap Meet was Re: [IC] Mulri-Vendor Marketplace

However in the above paragraph I think there is a great suggestion. Host a virtual swap meet. Interested people could have a table to fill. Set a time limit, like a week for the sale. I think a weekend is too short for virtual people. Let the vendors do the pricing and selling. Collect a fee for the table to cover the overhead. Social media could spread the URL of the sale. People could check in at their leisure. Like any other swap meet we would soon know who sells high, who sells bargains (and you have to get there earlier in the week), who is not reliable, etc.. Some sort of moderated feedback system would be a good idea. I think a time limit like a swap meet a good idea. It allows for transactions to be completed and not overwhelm the seller. Everyone will have to calculate their own shipping, just like we do now. Shipping weight with the description would be handy. And the vendor should set clear shipping rules for his table This method would keep the host out of the transaction and eliminate the need for a shopping cart. The Host could hold one every 3 months to cover expenses. We would soon know if it is a viable idea. And this route shouldn't cost as much. Vendors could sell one collectable to those of us that used to provide parts and would have multiple tables full. I think there should be a limit to how much fits on a table (or in a table space) just for control of bandwidth and give a way for the host to cover expenses. Just brainstorming here... I used to love selling at Ham and Computer swap meets. The internet allows for virtual communities. Why can't it allow for a virtual swap meet. Paxton -- Paxton Hoag Astoria, OR USA

PowerBook Duo 280c Disk Tools

by BHuntsman＠mail2.cu-portland.edu

Does anyone on here do much with old Apple gear? Anyone have a PowerBook Duo 280 or 280c? I'm looking for a Disk Tools disk image for System 7.1.1 for my 280c. Seems the Disk Tools disks were pretty heavily customized to squeeze everything required onto a single 1.44MB floppy. There are few images of Disk Tools disks for several different Mac families floating around the web, but I can't seem to find one for the Duo 280c. Any help is much appreciated!! Thanks in advance! -Ben

IBM 5150 with red case on ebay

by BHuntsman＠mail2.cu-portland.edu

I don't normally look at 5150's on eBay, but this one popped up in one of the ad tiles, and it caught my eye because I've never seen one that wasn't the standard beige. http://www.ebay.com/itm/Vintage-IBM-5150-Personal-Computer-WORKING-plus-acc… At first glance, it doesn't appear to be hand painted. Anyone on here know about such things? Were other colors available? Thanks! -Ben

DEC L2001 processor needed for stupid endeavor

by derschjo＠gmail.com

Hi all -- A year or so ago I picked up a VAXStation 3520 (a dual-processor machine), which I eventually upgraded to a 3540 (quad processor). Then I heard rumor it was possible to get it up to 6 processors, a configuration that was never produced or supported by DEC. I can confirm that 6 processors do work properly. As do 8 processors, for that matter... I believe that if I remove the graphics option, I can get it up to 10 processors, at which point I'm out of MBUS slots, thus hitting the maximum possible. I just kinda want to see it work. I'm still looking for something "useful" to do with 10 processors on VMS; it's a shame there was never a distributed.net client for VAX VMS :). I'm having trouble tracking down one more L2001 processor board. Anyone have one lying around they'd like to donate to a very stupid cause? Thanks, Josh (here's the output from the VAX 3580's startup with 8 processors: KA60 V1.2 F..E..D..C..B..A..9..8..7..6..5..4..3..2..1..0 5 01010004 L2003 4 ? V1.3 1 SSC 00000001 2 DZ 00031200 ? 3 NI 19210770 ? 4 SCSI 00000901 5 SYS 00000001 Tests completed. 00-E1,P1 03-E1,P1 08-E1,P1 0B-E1,P1 0C-E1,P1 0F-E1,P1 10-E1,P1 13-E1,P1 00 CPU00 >>>
