In searching through my pile of "stuff", I came across 38 of these unused chips still in the chip carrier. I am not at all familiar with these things (or most semicurrent chips for that matter), so are these (or could they be) useful for Classic Computer related projects?

IBM junk

by wdonzelli＠gmail.com

Lots of new IBM things today, but all basically PC related. Does anyone here have a 5182 Color Printer? This was one of the goodies today, from an ex-IBM salesman that was finally clearing out the closet. He said it was a very unsuccessful product from the XT/AT era, and may have never been for sale to the public. He said they were probably internal use only. The 5182 is a dot matrix printer with a four color ribbon. Kludge on a stick. Still, it is built like the mainframe people were in charge of the project. -- Will

Solder

by wdonzelli＠gmail.com

It seems, from a past thread, that leaded solder is starting to become a concern around here. I have a chance to buy some new 1 pound rolls, as well as some bar stock. In the pile is everything from Kester 44 to Ersin SN62 to noname company wire solder. Diameters are all over the place, from very small to quite thick. Prices have not been set, but it will probably fall in the 8-10 dollar per 1 pound roll area, maybe a hair more for the better stuff. What sort of _serious_ interest is there on this list? -- Will

Fuse for Apple /// power supply

by billdeg＠degnanco.com

Quick question - is the fuse for Apple /// power supply supposed to be a "125V 5mf 2 1/2 A" or a "125V 5mf 2 3/4 A" ? - I don't want to use the wrong one. The schematic appears to indicate 2 1/2 A, but the unit I have has a blown 2 3/4A fuse, possibly a replacement from the original owner. Don't know for sure. Why the fuse blew in the first place, that's a different question. Thanks. Bill

Toner as PCB resist (perilously close to OT)

by db3＠centurytel.net

Looks like I am a year late, but if you are still at this address I have some options for you. Have developed a system which works quite well and cheaper than most others. Jim

HP1000 'F' back on eBay (UK)

by javickers＠solutionengineers.com

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=160171142933 This is a completely complete system, one of a pair that I helped rescue >from Shell some years ago: I never got her to do anything past the self test (and, it would seem, nor did the buyer), so she's up for sale again... looking for a good home. Machine is in Preston, and requires a Luton-type van to transport (you could maybe manage with a high-top transit, but IIRC the cabs are 6ft high, which is taller than a high-top's cargo area). Cheers! Ade. No virus found in this outgoing message. Checked by AVG Free Edition. Version: 7.5.488 / Virus Database: 269.15.3 - Release Date: 19/10/2007 00:00

Did I get an RL01 pack instead of RL02?

by aek＠bitsavers.org

I bought an RL disk pack on Ebay, supposedly for an RL02 drive. It is a Memorex "Mark III T" the pack is defective (factory servo tracks are trashed) -- You bought a generic 5440 style pack. I saw that listing and the seller didn't know what he was selling. DEC packs have custom servo tracks. If it don't say 'DEC' on it it is highly unlikely to work in an RL0x

Things to do in SF before VCF

by evan＠snarc.net

Visit Sellam's warehouse nearby in Livermore. Seriously. And visit the Digibarn (although Bruce is always very busy preparing for VCF). Visiting Stanford is also fun, plus the HP garage down the street. Visit the Intel museum. Visit any number of differently theme Fry's stores. And of course, WeirdStuff Warehouse. None of that is in San Francisco, so just venture south a couple of days early. Speaking of which: I always rented Hertz cars for my past VCF excursions, because only they had the GPS option, but now Avis has it too. Got a really good deal when making my reservation yesterday -- four days with Avis, plus GPS, in a Pontiac G6 for aroun $150. Hertz wanted $200 for a subcompact.
