He wrote off to F.C. Williams for information, and received a reply probably on 8 July.
图灵为此写信给威廉姆斯,大概是在1948年7月8日,他收到了回复。
By this time, the fact was that they had already, on 21 June 1948, successfully run the first program on the first working stored program electronic digital computer in the world.
那边已经于6月21日,在世界上第一台存储程序式电子数字计算机上,成功地运行了第一个程序。
It used, for storage, the cathode ray tube that Williams had developed, and at this point the total store consisted of just 1024 binary digits stored on one tube.
这台计算机的记忆装置,采用了威廉姆斯开发的阴极射线管,全部的1024个二进制位,都存储在一个管上。
Alan drew attention to this figure in a table of 'memory capacities' in this report:
图灵注意到这份报告中关于"记忆容量"的一个列表:
Brunsviga 90
手摇计算器90
ENIAC without cards and with fixed programme 600
ENIAC(不算卡片和内置程序)600
ENIAC with cards ∞
ENIAC(包括卡片)无限注
ACE as proposed 60,000
计划中的ACE 60000
Manchester machine as actually working (8/7/48) 1,100
已实现的曼彻斯特机(1948年7月8日)1100
It was a pointed contrast between one machine still merely 'proposed', and another that actually worked.
由此可见,这台机器与那个"计划中"的机器存在着很悬殊的差距,
But the figures also pointed to the fact that F.C. Williams had pursued his project in a more modest way.
但这也说明威廉姆斯是以一种更务实的方式,来进行他的项目。
The Manchester computer was small, and might even be called small-minded.
曼彻斯特机器虽然很小,
But it was the first embodiment of a Universal Turing Machine, albeit with a very short 'tape'.
但却是现实世界中的第一台图灵机。
Alan wrote out a little routine to perform long division, and posted it north immediately.
图灵马上写了一段计算除法的小程序,并寄了过去。
