Surplus places in/near Vegas...

by kyrrin＠bluefeathertech.com

Fellow scroungers, I'm going to be in Las Vegas around the latter part of July. I would appreciate knowing about any surplus electronics places that would be worth a look. Thanks much. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

FS: ThinkPad 700C (SF Bay Area, free to good home)

by patrick＠vintagecomputermarketplace.com

I have an IBM ThinkPad 700C that boots Windows 95 (it actually runs nicely, I dare say better than Win2K3 on my current 1Ghz desktop). The display hinge is broken, so its aesthetics are lacking a bit, but if you've got another 700C that isn't working, this is a good machine for parts. Comes with power adapter, original docs, and battery (unknown condition). I'll ship to you for cost (US only, sorry), or if you're local you can pick up. If there are no takers, I'll be tossing it. Hopefully it finds a good home. It's a nice little machine, just outside my collecting scope. http://www.vintagecomputermarketplace.com/view.cfm?ad=1610 Thanks! Patrick

Build your %$@! computer here.

by cmurray＠eagle.ca

I quite agree. Here in Canada Radio Shack has moved into the mass consumer market leaving the electronic hobbyist to fend for himself. Here in the Toronto area we have access to specialty electronic stores that cater to our needs.

FREE: Toaster video tapes (copies). WANTED: Commodore PET ROM.

by dave04a＠dunfield.com

>Also, I need ROM 016 for my "chicklet" PET 2001. IIRC the 016 ROM is F000-F7FF. You can get the images of all the PET ROMs from funet. Depending on the board you have and the available replacement devices, you may have to build a little daughter card to adapt the selects - I did this many years ago when a ROM died in one of my 2001's - copied the ROM from the other, and made a board to adapt a standard 2716 - still going strong!

FREE: Toaster video tapes (copies). WANTED: Commodore PET ROM.

by tosteve＠yahoo.com

Hi, Something for the Toaster users among us - video tapes: - Studio 16 - LW Essentials - LW #1 2.0 - LW #2 2.0 - Modeler training, Toaster 2.0 - Displacement mapping, bones, morphing - Toaster Surfaces 2.0 They are all copies, but I viewed them, they are good. You can have them for the price of shipping (8 pounds). Also, I need ROM 016 for my "chicklet" PET 2001. Any givers? Steve. __________________________________ Celebrate Yahoo!'s 10th Birthday! Yahoo!

minor list changes

Well, it IS a serious matter for ME. If Jay is going to make this list hostile to people who actually run their entire business operations on Classic computers in the Classic manner (and exercise their right to use their own servers and not someone else's for sovereignty reasons), it looks like those of us *TRULY* into Classic computing need to start our own list (hosted on a Classic list server of course). der Mouse, can I count you in? I'm sure I can count on Tony... He is certainly *THE* most intelligent and most worthy person on this list. MS

Free: HP mini cartridges

by rigdonj＠cfl.rr.com

More finds from today's trip. One HP mini-cartridge factory marked "DGL Demo Mini #2 Mini Cart, PE, FMGR 24998-13309 Rev 2040". I don't know what the software if but someone here should know. The other tape appears to be a backup. It was orginaly marked "DB1000 CRTG#5" but that has been marked out and "!BCK03 R2540" has been marked in pen. Joe

Free: Tektronix Plot 10 mag tape

by rigdonj＠cfl.rr.com

I went scrounging today and found this. I can't use it but it's too good to waste so I thought I'd see if anyone here could use it. It's on a small tape spool and is marked "4010A01 Plot 10(R) Terminal Control System Level 5.01 (C)Copyright Tektronix Inc 1988 Format IBM ASCII 1600 BPI Label: None Serial No. B074512 Record: 80 Block: 800 Option: 08".

Catweasel opinions, sources of info etc.

by curt＠atarimuseum.com

Jim, I understand where you're coming from, however the way the product was presented, it stated it could read various formats, what wasn't mentioned on the site for the product or during the purchase process is that the "product is capable of reading such formats - if someone actually writes the code" My Atari 800 could run linux - if someone ports it, could run CP/M too if someone wants to write the needed code, could read IBM disks on its disk drives - if someone writes it... All of our equipment can do a lot more then it is normally capable of --- if someone takes the time to write it. So what I'm saying is I bought the product because it stated it could do certain things which I was expecting out of the box when I bought it, just there was no fineprint saying that there were no actual s/w or drives to actually make the card work that way yet.
