attention MITS fiends . . .

by edick＠idcomm.com

My problem stems from the fact that there are WAY too many things for me to handle at once, Sam. You wanted me to pack the stuff and have it shipped via an economical method but which required me to package and haul the stuff some 45 miles to the airport area. I just haven't the resources (personal) or the time to do all this under my present circumstances. What's more, I've had to move TONS more stuff from the basement to the covered storage outside, and it's pissing my neighbors off. Some of them understand, but many don't. Now, if you can think of a workable way which doesn't involve a major outlay on my part, in advance of the fact, and doesn't involve many hours of packing and hauling time, mine, I mean, since I have to pack and haul from inside the house to outside, I'm listening, so to speak. Those ALTOS boxes I bought on your behalf are still in the car, by the way, but I can't open the trunk because I was rear-ended by an illegal alien with no insurance . . . In the meantime, I'm going through the just-now-moved stuff to ensure I don't expose otherwise sensitive and potentially fragile hardware to unfavorable conditions. What this amounts to is looking through the stuff I've had help to haul from the basement in the last day or two, in the dark, and examine it in the daylight, to ensure it retains some of its remaining worth, if I can do anything to that end. Keep in mind that I'm stressed to the MAX right now, because I have a new 30-hour-a-day, 8-day-per-week job for anew client, in addition to all this other headache. What's more, I'd like to avoid the exchange of dollars for anything other than expenses because of the accounting headaches that creates. I had this stuff in two sections of the basement because some of was known to be of some value and therefore worth preserving. That's of less concern to me now than it once was, but it is of some importance to me to avoid discarding the stuff in a way that will result in no benefit to anyone. I'm willing to ship, via USPS because I visit my P.O. box several times a week, those items I can easily ship. I have physical limitations which render me unable to lift items with much weight or raise my arms much above the level of my shoulders. I don't have a lot of boxes in which to ship things, nor do I have the time or the desire to shop for boxes and packaging materials. I would, of course, consider bagging a board or documentation, and taking it to Mailboxes, etc, to have them package and ship it at the expense of the recipient. However, I don't have lots of cash to invest in speculation on COD shipments. I can do this a little, but I have a boy at Harvard and one (who didn't want to go to MIT because his brother was already in Boston) at Georgia Tech. You know that's not free! The reason I decided to get into the pile of miscellaneous hardware and move it out is because I'm in the "proof of concept" stage with my new client and while packaging doesn't matter at this point, I do have to have hardware on which to implement the concepts and I no longer go out and buy, randomly, hardware which suits the task, first because it often doesn't and secondly because it ultimately winds up in "the pile." I doubt that you intended to publish this communique' but I'm also publishing my reply so I won't have to explain to every individual why I don't have inventory listings of all the stuff in "the pile" or in "the heap." This stuff is the product of over twenty five years' accumulation of hardware I bought at market price and which has not found another home . . . yet. I remember what some of this stuff cost, so I'm reluctant simply to toss it where it will produce no further value. Those old Apple-]['s still do, faithfully, the job they could do back in the '70's, though no better, and the CP/M boxes will still turn out the payroll, though not in color and without the fancy noises. I try to pass this stuff on to people who will get some benefit since it's worthless lying around unused. Clearly, you're in the business of distributing such items as we discussed before. I have no problem with that. I just can't afford to expend my limited resources making the business of getting these items moved to your venue convenient for you. Things were different two to three weeks ago, when I didn't have the trunk of my car sealed by the damage, and when I didn't have the problem of making room for additional residents in my house. As I've said before, I don't mind giving stuff away to someone who will use it. If I "get" something for it, I prefer it not take the form of cash, because of the tax-related bookkeeping hassles. As I pick my way through "the pile" looking for resources I can use for my present task, I'll make a list of what I see. In some cases, I'll know I have other parts, or documents, or whatever, which might "go with" these and probably won't have time to find them. I will however offer a partial list as time allows and as I go back inside to "take a load off." Does this make any sense to anyone?

Need data sheet for 1101 RAM, 8008

by dastar＠ncal.verio.com

Does anyone have the data sheets for the 1101 RAM and the Intel 8008? I need both. In the case of the 8008, an instruction set listing would also be cool. Anyone know where 1101 RAM chips are for sale (if at all?)

Avail: 50-pin cables/rack-panel/connectors for unknown system

by ss＠allegro.com

Hi, (hoping this version makes it past the classiccmp filter :) Free to any home: (pick up in Cupertino, or pay shipping) two 5 meter (?) cables, with female 50 pin AMP connectors on both ends (three rows of holes: 17, 16, 17). The cables have tags reading: 422-0018-018 REV C RMH one 19" panel (about 1.5" high) with two male 60 pin connectors (matching the ones on the cables). These two connectors are wired to two long ribbon cables (3 meters?) that both end in 50 pin card connectors of some kind. The male connectors on the panel are labelled J1A and J1B. These were bundled into a surplus purchase, and have absolutely no connection with the computer I got! thanks, Stan Sieler sieler(a)allegro.com

attention MITS fiends . . .(NOW PACKING AND SHIPPING)

by jlwest＠tseinc.com

>Packing and shipping though is a straight forward problem, which I would >love to see a discussion of. > >Heavy old junk. >The only thing I see practical here is the personal transport option, stick >it in the trunk, back of the pickup, etc. I am curious about the creation >of some sort of hardware hitch hiker pool, so people going from one place >to another anyway, might consider hauling some junk for others besides >there own junk. With regards to shipping, here's my "magic" solution (like there is one) ;) Find an associate (friend, spouse, customer, etc.) who works somewhere that does a lot of shipping. These companies get HUGE discounts off shipping costs from folks like roadway, ups, etc. Then see if you can have them do the shipping in to their warehouse, and you pick it up from there. You of course offer to pay their shipping cost outright (still a huge savings for you off normal pricing) or you can setup a barter arrangement with the company (like helping with their PC network). Case in point - I'm having a pallet with a HP21MX rack, including 15231 power supply (heavy), cpu (somewhat heavy), and 7900A disk drive (VERY heavy) sent to St. Louis from California. Normal roadway shipping cost is around $695.00. However, a customer of mine does a lot of shipping and their cost from roadway is $195.00. I'm doing side consulting work for them to pay off their cost, but in a barter arrangement you could easily offer them a bit more work/time in trade than their cost for their trouble. That all being said, I've driven hundreds of miles to pick up something for my collection. But in a pinch, the above method can be better at times. I myself would be MOST interested in forming some type of hardware pickup arrangements with folks in other areas. I'll pickup stuff in my area for you - you do the same for me in your area. Then once every so often several of us could meet halfway to exchange the stuff for others and/or ourselves. Perhaps each person gets partial gas reimbursement if it's only equipment for others... who knows - I'm just throwing out ideas for all to throw stones at. FYI - I'm in St. Louis, MO - a nice central location, so I'd be happy to hold onto those 5 altairs and 8 imsai8080's for ya <grin - just kidding - I don't even collect micro's> Finally - I'm going to be in Irvine, CA (flying into LAX though) march 3,4,5, and a bit on saturday the 6th. Two questions - 1) Can anyone direct me to any favorite surplus/salvage stores in the area I can scavenge in my spare time while I'm out there? and 2) If anyone on this list is in the Irvine area, I'd be happy to buy ya a cup of coffee and exchange stories about when computers were real computers :) See ya!

21mx system I bought...

by jlwest＠tseinc.com

Ok folks - since everyone and their brother is asking.... Yes, I *DID* get a 21mx system from Berman today. However, that is not the 21mx system I was referring to in my post. I got two 21mx systems today, both from california (one from berman), but >from different places there. BTW - does anyone have HP 21mx M series cpus(2105a, 2108a, 2112a)? I'd be willing to trade 21mx E series cpu's for them. The E series I have are faster than the M's, and completely compatible (except for timing dependent program loops due to the faster speed). The software I want to run will run better on the M's - so... Let me know! Jay West

question about viruses

by allisonp＠world.std.com

<The first article I ever read on computer viruses was in the Los Angeles <Times in 1986. In fact, I clipped and saved this article (and many <others) and still have it in a file folder laying on a shelf in my bedroom <closet. They are far older. <The author then accurately predicted the explosion of computer virus <attacks. In 1986 I was just playing around with computer timebombs on the <Apple ][ (one of my dumb friends actually used my program on an <unsuspecting fellow computer class student and got reamed out pretty good <by the teacher) but viruses were pretty scarce. A few years later and <they started to become a major nuisance. The first one I know of ram on TOPS-10 V3.x and was a monitor virus (using modern terms). It was a hack to open the security door. That done we created cancer that was a program that did nothing except copy itself. that was back around '71. There were telco virus as well in teh 70s with the advent of ESS. back in late '69 on a PDP-8I we ran a Trogen Hourse to get passwords and spoof people (written in pal-III!). Allison

NEC APCIII - Any insights?

by roblwill＠usaor.net

Hi! My school has an old NEC APCIII. All I know about it is that it's an AMD 8086-2, and had a hard drive and floppy drive. What I want to know is if there is a way to make it boot from the floppy. I turn it on, it beeps, sits for about 2 minutes, says : DOS 2.11 command interpreter, then locks. it only beeps when a key is pressed. Any ideas on how to get into setup? -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1>

Amiga 1000 boot ROM & Kickstart 27.5(!)

by mark_k＠iname.com

Hi, Are there any people who have Amiga 1000s on this list? If so, please contact me, even if you can't help directly with the things mentioned below. Boot ROM -------- Inside the A1000 there is a boot ROM whose purpose is to load Kickstart from disk. In normal use -- after Kickstart is loaded -- this ROM is not visible. I want to try and get the data from the boot ROM dumped to disk; it will be interesting to disassemble this and see how it works. To do this requires using a little trick (involving the RESET instruction), which only works when Fast RAM is present. I can write a program to hopefully allow the boot ROM data to be dumped. This would need to be run on an A1000 which has Fast RAM. Please let me know if you're interested in helping with this. Kickstart 27.5 and early Amiga demos ------------------------------------ Many years ago, I received a catalogue disk from an American company called Chiron Conceptions Public Domain, who used to advertise in Amiga World magazine. Listed there were some very early Amiga demos, used for the Amiga launch in 1985. They require a pre-1.0 Kickstart, version 27.5, to work. I would really like to get hold of any of these demos and Kickstart 27.5. Below is the listing from the PD catalogue. VERSION 27.5 DEMO DISKS ======================= CC-001 --VERSION 27.5 KICKSTART Prerelease version of Amiga Kickstart. Needed for some disks. (NOTE: Will not work on the Amiga 500 or 2000). CC-002 --AMIGA SHOW STOPPER PAK Includes two of the demos shown at the Amiga debut at Lincoln Center: Eagle Demo Watch the eagle as it swoops over the digitized mountain range. Listen to it's screams as it glides across your screen! An endless loop demo. Ballet Stills A series of superb digitized graphic stills of a ballerina. (NOTE:Requires Version 27.5 Kickstart (CC-001) and thus will not run on the Amiga 500 or 2000). CC-003 --ISLAND GRAPHICS DEMO SET A two disk set of graphics pictures and animations demonstrating the Amiga. Very nicely done. (Requires external disk drive & Version 27.5 Kickstart-(CC-001) and thus will not run on the Amiga 500 or 2000). CC-004 --ELECTRONIC ARTS GRAPHICS DEMO A two disk set demonstrating Amiga's music, graphic, and voice abilities. Includes digitized voice, scenes from EA's Amiga software, music, and digitized photos.(NOTE: Requires 2 drives, 512K, and Version 27.5 KickStart (CC-001) and thus will not run on the Amiga 500 or 2000). Regards, -- Mark

Xerox 820 family almost complete

by allisonp＠world.std.com

<Two questions: < <Is there still a source for 5.25 inch CP/M for the Xerox 820? That machine had a lot of mods and people working on it so I'd say likely. If you can fid the sources it's not that bad to edit and reassemble. <Was there ever a 5.25 inch floppy/ hard drive combo offered? Unknown on that but I'd bet yes. Allison
