project OPEN DAY LINK:-News of the Planned 2005 OPEN DAY

After a visit from the Hon Secretary of the Computer Conservation Society ( Hamish Carmichael ) and Martin Wright as co-ordinator of 1301 information for the pilot stage of the Computer Conservation Society's "Our Computer Heritage" project. on Saturday the 6th December 2003.
Both the owner of flossie and myself are now known as 'the 1301 Working group'. We are most happy to be part of the
"Our Computer Heritage" project

* Brief Activity Summary *

As of the end of April 2003, the project had started, and started well, the machine does indeed fire up, and although there are many problems, sufficient of the machine is working to raise my spirits and allow me to hope the project can be completed. I am working with Roger, who owns the machine, and we manage to get together, for about a day, every two weeks or so. If you read the repair diaries you will discover we have closed the activities for 2004, and plan to restart in april 2005.

The latest diaries are :- Here

Statement of the problems and issue's

This elderly machine is called Flossie, now my father advised me to never ask a lady her age. But the truth is that Flossie was built about 1961, spent a working life at London University, where one on her many roles was to produce GCE exam results, in about 1972 she was retired into private hands. So the age of the machine combined with the number of years since it last ran reliably, means we face a combination of many faults. For example, it was noted that 3 out of 10 of the programmed indicators, do not work correctly. However to resolve these problems, means we need a reliable Cpu decode of the functions required to fault find further. That coupled with the simple fact that at each switch on or off we risk a new fault being added to the growing list and some of our problems may just be either cold or warm up related.

So all we can do is tackle each problem as it is identified or as it occurs, in the certain knowledge that it is one less problem to be resolved, when it is out of the way. The 'PLAN' is to work on the problems as follows:- 1st step is the basic control path based around Control registers one, two and three, the function decode, and the Register 'A' path, 2nd step is the IAS access, and load/store functions, and register interchange functions on registers 'B' and 'C' . 3rd step is the drum transfer functions, further successive steps are into the tape control unit and then we can start to tackle the peripherals.

More updates as and when we visit. Do check back for pictures, updates and news on this project.

** Appeal for Historic tools **

To complete this project we are in need of any old 1301 wire wrapping tools, which engineer's may still have tucked away in old tool boxes, so if you think you have one of these and wish to donate it to the project, then email us on:-

Thanks go to contributors so far:- "Roll of Honour"
