Motor generator

Many thanks for all the info. I just wanted to make sure my recesses were right. I asked about MG because, in an audio forum, I see folks paying crazy money for AC cords and power line conditioners. I thought a good MG would solve many of the 'problems' they are trying to fix.

Motor generator

In the deep recesses of my mind I seem to remember something about S/360 machines using a motor generator. If I am right was this to create a stable power source at a certain frequency or voltage?

Re: BYTE Magazines

Computer Museum of America might be interested. They have a Byte wall. http://www.myimagecollection.com/webpics/cmoabyte.jpg Contact Lonnie Mimms lon...@mimms.com to see if he has any interest. Donald

Looking for new punched card type

Peter, I have several Port-A-Punch cards. Would you like 1 of each? Do a search at www.ibmjunkman.com and check Holders 162, 568 and 1856. Donald

Unusual Punched Cards

This card is shorter than 40 columns but I can't tell if it has been cut off or not. I only have 1 so I can't let it go. http://www.ibmjunkman.com/cards/?Holder=2551 =0 You can search on Style and select different ones.

Re: Old IBM magnetic media

I had an old IRA 7340 Hypertape cartridge. It is at the Computer Museum of America. I still have a cartridge but don't know from where. I just got some replacement strips for a 2321 Data Cell.

Old IBM magnetic media

Just received my latest eBay purchase. 5 3850 MSS cartridges. 3 of them had no tape inside. Just wondering why. Data destruction? Inquisitive previous owner? 1 of them has an opaque yellow shell instead of the smoked clear plastic. Possible CE cart? Has magic marker printing on it BAD MSS TAG I

IBM 026/029/129 ribbons

Just for reference the following site has ribbons for the subject card punches. https://www.aroundtheoffice.com/IBM-026-Keypunch-Ribbon/productinfo/RP-520-I BM/ I bought some a few years ago. As I understand it he makes a batch every year or so. I don't know but he might like the used reels

What is this?

Re: Old CE manuals

I sent a mail to Al at a...@bitsavers.org on 4/11 regarding a bunch of IBM manuals. http://www.myimagecollection.com/manuals/ Never heard back so they went into the trash. These manuals are decades older so I don't want to trash them. If Al jumps in here, fine. He can get them.

Old CE manuals

Still cleaning out for Nevada move. http://www.myimagecollection.com/cemanuals/ Last 2 are interesting. 2075 Processing Unit and some Russian machine EC4001. Number sounds familiar from my eBay sojourns. Available for cost of Media Mail shipping. These buggers are heavy. As last

Re: 3850 media

2nd seller indicates he is the first seller. Just selling on UK eBay. Don’t think you need different IDs to do that but what the hey. Whatever floats your boat.

IT books available

Listed these on eBay a few times. No takers. Being offered here for the price of USPS Media Mail cost. Total of 52 lbs of books in 2 boxes. I estimate shipping at $137. Price will be actual shipping cost payable by PayPal. See books at http://www.myimagecollection.com/ITBooks/

Don't think it is IBM. Apparently high temp ICs due to the heat sink housing. No idea what it is. http://www.myimagecollection/part

I assume you have a standard search set up on eBay? That is where I got mine.

Re: IBM junk

I don’t recall if I had any 3880 documents. I will ask how they would like to handle this type of request. There are many duplicates and they will need time to catalog the documents.

Re: IBM junk

I don’t think so.

Re: IBM junk

The whole collection went to Computer Museum of America in Roswell, GA https://computermuseumofamerica.org/

Re: IBM junk

Well, not really. CHM only wants my punched card collection (4000+ cards) which they are getting when I croak. Did not want the other stuff. Livingcomputers only interested in miniatures. I will swear I sent a note to Al Kossow about manuals. No reply.

IBM junk

Collected stuff for over 10 years. Moving from 2300 sq. ft. to 1400. It had to go. Praise the computer gods I found someone that wanted it all. 115 boxes of manuals and documents. 26 boxes of coffee mugs 73 703 boxes of stuff. 106 loose big items. Filled the floor space of a 26' truck. It can

Re: Amusing IBM test system model

Well, the ones listed now have been re-listed at least once. :-( I was just contacted by the Living Computers Museum. They emphasized they are a 501(c)(3) org. :-) I donate to the CHM. I will probably give them first shot.
