Just wondering. The 1442 had a primary and a secondary stacker. What happens once primary stacker is full? Could that be sensed and then further cards would be directed to the alternate stacker? Or did both stackers operate the same switch?

By the way, I do have a question about this memory card. The one I recall seeing back in 1971 was larger and had little cores with wires strung thru them. Was there more than one type of memory card?Hello all,In 2004 I purchased on eBay a "Core storage plane from IBM 1130, 1800, 360". It has spent most of the intervening years in a storage locker. I have since moved to France; a friend is helping me dispose of my State-side "treasures". If someone would like this, please reply to this email, and my friend will mail it to you. Anybody rebuilding or servicing an 1130 gets first dibs. Otherwise, first come, first served.
And now for a bit of history: I'm a co-inventor on a patent for a software system I programmed, using Fortran II on the IBM 1130. If interested, you can look it up here: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/netahtml/PTO/search-bool.html&r=22&f=G&l=50&co1=AND&d=PTXT&s1=eiben.INNM.&OS=IN/eiben&RS=IN/eiben
The patent was applied for in 1971 and granted in 1983, long after I had left the firm where I wrote the software. Like most patents, nothing came of it.
I was told the 1130 with the 1403, 082, internal hard disk (2311?), plotter and key punches rented for $6 000 per month. The beast had 32kb memory, and I used SOCALs and LOCALs quite a bit to get programs to load and run.
Bonne année !

HarveyMichel,I sent the email about the availability of the 1130 memory card to the email exchange that is interested in the IBM 1130. Below are the responses. Is it possible for you to take a photo of the card and to send it to me? If so, bear in mind there is no rush.

That’s the real deal, There is one in the Technology Area at Bridgewater College, Bridgewater VA. I was the first Manager of the C.E. Shull Computing Center and when that machine was finally removed from service, I removed the memory and it was placed in a showcase in the Science Building.
