Elliott 803 emulator on ICT/ICL 1900

ex-Elliott buffs may not be aware that ICT/ICL developed an 803 emulator for its 1900 series computers. I was involved in a project in the 1970s, using this software to replace an ageing 803 by a 1901A or 1902A. The customer, a large German building company, had a lot of technical programs running on the 803 (from paper tape), so we had to come up with a way of porting these to run from disc under Exec. --TraceyR 18:18, 27 June 2007 (UTC)[reply]

Rewrite

I have largely rewritten the entry to remove the dependence on copyright material (which is currently inaccessible anyway). Richard Pinch 21:09, 30 June 2007 (UTC)[reply]

The 803 did not use Baudot code, it used Elliott telecode, in which the letters were arranged in alphabetical order.

12*4$=78',+:-.%0()3?56/@9£
ABCDEFGHIJKLMNOPQRSTUVWXYZ

The last five codes are figure shift, space, carriage return, line feed and letter shift.

I've added a comment to the effect that the instructions 66 and 67 (short divide and square root) may have been enabled on more machines than just those destined for process control. I tested these instructions on the 803 at TNMOC yesterday, and they do work!

Past/Present tense

Since TNMOC's 803 is still operational I think this whole page needs rewriting in the present tense! 86.145.207.63 PeterO (talk) 22:57, 5 April 2010 (UTC)[reply]

Minsk series of computers reference

I removed the section that claims that Soviet Minsk computer series was copied from Elliott 803. This section did not have any references and is factually incorrect. The architecture of Minsk was completely different from the one of Elliott, even word size was different: 39 bits for Elliott and 37 bits for Minsk (31 for earlier models). Autocode Inzhener was not a copy Elliott Autocode either.

CRAM on Eliott 4100 series

I was working on this computer at the Paris University, I think about year 1968. There was an incredible peripheric called CRAM (card randon acess memory ?) This was an incredible device consisting in about a hundred of magnetic cheets stored in a special box. On access one of the sheets was driven on a reading rotating drum able to read 64 tracks with 64 different heads. This was the start of the random access All was driven by vacuum air circuits. A lot of sheets crashed on their way to be read or written or back to the store unit However it had a great success compated to magnetic tapes. Does anyone has user manual or picture of this incredible device? Thanks p.testemale@gmail.com — Preceding unsigned comment added by 176.140.103.62 (talk) 11:11, 23 April 2019 (UTC)[reply]
