Museum of IBM 360 and 370 computer systems collected over the past 30 years.
Welcome to www.punch-card.co.uk the online computer museum hosted By Webseen Ltd. The collection is based around IBM systems of the 1960's, 70's and 80's, all collected over the past 25 years. The collection started with the front control panels of various 360 and 370 systems that we had been maintaining. In addition to the Mainframe artefacts we also have a number of GSD systems such as 5332, 5334, 5336,5381 and 9406 as well as various specialist tools and test equipment. I am always pleased to here from other collectors and museums and would appreciate your comments via our feedback page or E.mail email@example.com I will be continuing to upgrade the site throughout 2000 and do appreciate any input that you can give.
I have put this on-line collection together over the past 25 years. It has been on the internet for the past three and this is my first major update. The collection started with the front control panel of an IBM 360-2040 that we were maintaining in 1979. At the time I was working with Fee Maintenance Services a new small UK third party maintenance company. I had worked throughout the 1970's for various Plug Compatible Manufacturers and TPM companies. By coming into IBM systems and peripherals from the PCM background I developed a keen interest on how IBM had come to dominate the computer industry.
As I watched machines being scrapped for the gold and other metals (still containing parts I so badly needed) I started collecting not only what I required but also what were obvious magnificent pieces of electronic and mechanical equipment.
Much of what you will read here is my own interpretation of machines and events. If I am not accurate or you have input that will add to the detail then please use our feedback form and I will update the site when I can.
The collection started with 360 Mainframe equipment and for most of the early years I only concentrated in that area, moving on to 370 equipment and recently collecting anything that is left that has not been scrapped. Sadly most documentation was thrown away and now trying to find original information is becoming more difficult.
AS engineers we have also managed to collect a large selection of tools and Test equipment for IBM systems and associated peripherals. This includes CE disk packs and I/O test and diagnostic devices.
We are continually updating the Mainframe collection and recently I have been rescuing parts from various plug compatible suppliers. I am always looking for new (old) equipment, we do have substantial storage available. If you are a collector please contact us. We are always interested in other collections and information and any additional detail on our own exhibits is always welcome.
The IBM 360 range of computers were first introduced in 1964. The range was designed to be "General Purpose" and used for both Data Processing and Scientific use. All machines shared the standard 360 Instruction Set. Upward compatibility was designed to give the users a growth path that enabled them to keep their investment in both data and programs. This compatibility extends to some extent right up to today's new CMOS processors. Another major part of the design was that the systems could emulate the earlier 1401 range, again this offered the users the opportunity to continue to use their older programs. The systems were built using IBM's latest Solid Logic Technology (SLT). SLT used micro-miniaturisation of transistors and diodes, these circuits were then packaged in half inch square modules. Within the tools and test section of the Museum you will find descriptions of both SLT circuits and their power supplies.
