Dear Mr. Allain hello. If nobody else is interested I would like to have it, if you don't mind sending it to Fairfax, Virginia. I'll pay of course for packing and postage. Thank you in advance, John Savvidis -----Original Message----- From: John Allain [mailto:allain@panix.com] Sent: Monday, April 19, 2004 6:58 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: save the Mac II (original) Would somebody please take my Mac II? I saved it from being scrapped at the office because of it's history, in that it was Apple's big redesign, the first machine of the new line -- one that completed with IBM's PS/2 line and argubly was a greater success. I'm not a big Apple expert but it just seemed if you were going to have a few Macs that this model would be in the top 5. This one comes with a HiRes graphics card, matching Ikegami monitor (17" but compact) cables, software, etc. They don't seem to be that common, when you strip away all the variants, I haven't really found a place to get this original model. Help save the classiccmp. John A.

HP E-series computer?

by vax3900＠yahoo.com

My friend told me that they are going to get rid off a HP E-series computer from their storage. It is a big box with two rows of switches on the bottom half of front panel. I am a vax guy and need some $$$ to invest into my 3900. Do you guys think it worths to epaying it? Thank you. __________________________________ Do you Yahoo!? Yahoo!

Does anyone have National Semiconductor's Appnote AN-359?

by dickset＠amanda.spole.gov

I have this INS8073-based board with four TIL-311s, an 8255, a 6116 and a socket for another, an 82S23 PROM, and an MM58174A. The MM58174A is a clock/calendar chip for which I can't seem to get the appnote for. Google reveals an old location at the Nat'l Semi webpage (it has been removed from their appnote dir), and a single reference at http://www.nalanda.nitc.ac.in/industry/appnotes/Natsemi/AN-359.pdf which refuses my connections (could be down, could be blocking U.S. access; not sure which). I don't care if the Digital Library of the Calcutta Technical Institute is up or not; all I'm after is the app note for the MM58174A. Does anyone on the list have the file 'AN-359.pdf'? Thanks, -ethan P.S. - I realize a picture speaks a thousand words, but does anyone recognize the device I've described? It was a gift from someone, years ago. I brought it with me both as a source of TIL-311s and because it's a complete INS8073 SBC. From what I can gather so far, it's pretty close to the Nat'l Semi reference design, down to using a 741-style RS-232 converter for the console interface. The only useful markings on the PCB are "MC-1N REV-A". The layout of the TIL-311s and the four pushbuttons on the corners of the front panel suggest to me some sort of digital timer. There's a 2x5 jumper block on the front that appears to be input power, serial in/out and a few of the CPU flag pins (F2, F3). There's a 1x9 jumper block on the back that seems to be just options, not I/O, but I haven't traced the whole board out yet. P.P.S. - in case you don't recognize the CPU part number, INS8073, it's a microcontroller with Tiny Basic onboard - you wire on a level shifter, an SRAM and an optional ROM, and _bang_, a microcontroller with a built- in development system. It's the same processor used in the RB5X robot. I have had this board for years, and last year, I picked up a few CPU chips on ePay for a few bucks each. They are one of the many classic toys I brought with me to play with through the long, winter night. -- Ethan Dicks, A-130-S Current South Pole Weather at 18-Apr-2004 13:50 Z South Pole Station PSC 468 Box 400 Temp -70.8 F (-57.1 C) Windchill -94.5 F (-70.3 C) APO AP 96598 Wind 6.2 kts Grid 074 Barometer 689 mb (10289. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html

TDC1007 / 1007 / TRW / Rare TRW Processor ?

by Innfogra＠aol.com

I have seen some of these before. I had some like this from TRW. Not sure of the numbers though. I remember the TRW was printed on a piece of aluminum which was glued on top of a plastic chip. IIRC one I peeled apart had an AMD 2901 underneath. Most did not have anything printed on the plastic underneath. Seems TRW was quite propriatary. I also had some that I thought were 68000s underneath but with absolutely no markings. We had to take the aluminum cap off before they could go into scrap. Never saw one glued to silicon or ceramic. 2901s were at the heart of some early computers but is not worth the $175.00 that the seller is asking. Paxton Astoria

simple apple questions

by dave04a＠dunfield.com

>You really need the original Apple ][ Reference Manual. Let me know if >you don't have a copy and we'll rectify that. I have the Apple][ reference manual and a whole pile of other Apple reference books and material scanned ... I'd like to make this available, but I have not done so due to the copyright question - posting a published book which was sold on it's own merit seems less legit than manuals which came with hardware. Anyone have any thoughts/experiences on this? Regards, -- dave04a (at) Dave Dunfield dunfield (dot) Firmware development services & tools: www.dunfield.com com Vintage computing equipment collector.

I'd like to make this available, but I have not >done so due to the copyright question - posting a published book which was sold >on it's own merit seems less legit than manuals which came with hardware. >Anyone have any thoughts/experiences on this? A quick follow-up to this before anyone "jumps" on me - I would not even think about posting something which is still available from standard sources - I have not checked to see if you can actually still buy an A2 reference manual from anyone - perhaps there's someone with a warehouse full of them? As noted above, this is not something that I am currently considering. This is more of a "distant future" question - at some point the original material will not be generally available (this may already be the case for some of it), and people wishing to learn about these historic machines will have to either borrow it or steal it (photocopy/scan etc.) - as books get older, rarer and more fragile, borrowing will become harder and harder, as will physical replication. Are there any procedures in place to allow this material to be preserved, or does it just "die off"? Many of the manufactures of obsolete computer hardware/software that I have been able to contact have been very helpful. For example, when I asked Dr. Grant, co-founder of NorthStar computers if I could post the NorthStar OS & software (under my simulator) and scans of NS documentation, he responded "North Star is defunct so there is no problem whatsoever. Have fun.". I've had similar responses from a number of other people who "own" dead computer companies. Books however are a different matter, with published books, you have both the Author and the Publisher with interests in the book. I think it would be a lot more complex to obtain similar permissions, but to be honest, I have not tried - anyone here ever gotten permission to distribute the content of a published book?

simple apple questions

by ron.hudson＠sbcglobal.net

Hey all you AppleII gurus... I am starting into assembly/machine code on my apple IIc+ If I am in the monitor - how do I get back to basic? If I am in basic Call -151 takes me to the monitor right? If I am in the monitor A ! takes me to the mini-asembler URL for reference for the monitor? for the mini-asembler? What do I call to get a character? to print a character? Where is the best place to put my Assembly/Machine code program? Other pointers, tips, opinions, suggestions? Thanks!

DEC VAX 785 and PDP11/70's in Kansas City

The proper way to make a real PDP-11 (or VAX or any other Classic computer) available to everyone who wants one is put them back in FULL PRODUCTION. Not just hobby, but real full production and commercial sales (for a reasonable commercial price). I'm working on a new VAX chip and will soon be putting VAXen in full production. I can't do the same for PDP-11 because it just isn't my area of expertise, but my close fried, comrade and associate Stacy Minkin is more on the PDP-11 side and wants to build a new PDP-11 using FPGA technology just as much as I want to do it for the VAX. If you want new PDP-11s, E-mail him at stacy(a)ivan.Harhan.ORG and tell him that you want to buy a PDP-11 and would be willing to pay a fair commercial price and possibly finance the NRE cost. Stacy is a real engineer with a vision just as grand as mine, so given enough people willing to buy this stuff (for real, commercially, just like in The Days when it was new), he and I can build The Real Thing: real microcoded CPU, honest-to-Daemon UNIBUS, etc., not a poor man's emulator.
