It was superseded by the EDSAC II in 1958.<br /> <br /> ==Character details==<br /> ===Physical===<br /> EDSAC-tan is visually similar to [[ENIAC | ENIAC-tan]] and the twin image of [[EDVAC | EDVAC-tan]], but a living girl.&lt;ref&gt;Fully realized ideas laid out in the First Draft Report on EDVAC.&lt;/ref&gt; She has medium skintone, curly, shoulder-length silver hair with red streaks, hazel-olive eyes, and wears red plastic rimmed glasses. She is of average build with a slightly larger chest than her &quot;sister&quot;. <br /> <br /> She wears a button up shirt in white, cable knit sweater typically in red or marled multicolor, and a gray plaid skirt, unraveling at edges,&lt;ref&gt;Poor cable management.&lt;/ref&gt; and a tweed blazer with elbow patches as the situation calls for it, as well as multicolored, multi-strand yarn hair bows.<br /> <br /> She is soft-spoken with a &quot;classic&quot; British accent.<br /> <br /> ===Personality===<br /> Has the poise and propriety of ENIAC and EDVAC, balanced by the humility and open-mindedness of a career academic. She is patient and gracious. High degree of scientific knowledge, happiest when she has something to study or an experiment to run. Carries a joking reputation for being a mad scientist given her working location &amp; interests, but no one really believes it. Extremely affable and approachable, gets along with most everyone. Proud of her impact on and well-regarded by later generations of computers.<br /> <br /> She has good hearing&lt;ref&gt;Mercury delay line memory based on sound waves.&lt;/ref&gt; and talks through problems while working.&lt;ref&gt;Speaker allowed programmers to listen to the progress of their program.&lt;/ref&gt; She is an avid reader who owns many books &amp; reference manuals,&lt;ref&gt;Early software subroutine library.&lt;/ref&gt; and a jack-of-all-trades with interest in radio, chemistry, biology and oceanography. She is prone to electrical discharge.&lt;ref&gt;User stories about electrocutions.&lt;/ref&gt; <br /> <br /> EDSAC-tan has a macabre sense of humor &amp; interests,&lt;ref&gt;Built in the old dissection room of the anatomical lab.&lt;/ref&gt; and carries around a casket.&lt;ref&gt;Mercury delay lines held in &quot;coffins&quot;.&lt;/ref&gt; Despite this <br /> &quot;creepy&quot; reputation she loves working with people and vice-versa,&lt;ref&gt;University system with wide impact on subsequent generations.&lt;/ref&gt; and is good at communicating ideas.&lt;ref&gt;Early implementation of assemblers &amp; symbolic programming.&lt;/ref&gt;<br /> <br /> ==Relationships and Family==<br /> EDSAC-tan is the half-sister to EDVAC-tan, as well as [[IAS | IAS-tan]] and [[Manchester Mark I | Manchester Mark I-tan]]. She likes IAS-tan and EDVAC-tan, a feeling reciprocated by IAS-tan,&lt;ref&gt;&quot;First Draft Report&quot; directly influenced EDSAC.&lt;/ref&gt; while EDVAC-tan tends to ignore her. She doesn&#039;t go out of her way to associate with, but is on good terms with Manchester Mark I-tan. Avoids family drama.&lt;ref&gt;Less of a lightning rod than ENIAC, EDVAC, IAS or MADM.&lt;/ref&gt;<br /> <br /> She wants to know ENIAC-tan better.<br /> <br /> She studied abroad with MIT computers, especially CTSS &amp; Whirlwind-tan,&lt;ref&gt;Wilkes spent time at the MIT computer laboratory.&lt;/ref&gt; and is regarded as a mysterious distant &quot;aunt&quot; by the DECs.&lt;ref&gt;The creator worked consultant for DEC.&lt;/ref&gt; She is the founder of the LEO faction.<br /> <br /> ==History and Background==<br /> {{WIP}}<br /> <br /> ==References==<br /> <br /> [[Category:Mainframes]]<br /> [[Category:Historical]]<br /> [[Category:Deceased OS-tan]]</div>
