Question: Which computer, the Digi-Comp I or the Acorn Electron, was made as a budget friendly version of the BBC Micro educational/home computer?

full_context: Document 1: Mechanical counter: Mechanical counters are digital counters built using mechanical components. Long before electronics became common, mechanical devices were used to count events. They typically consist of a series of disks mounted on an axle, with the digits 0 through 9 marked on their edge. The right most disk moves one increment with each event. Each disk except the left-most has a protrusion that, after the completion of one revolution, moves the next disk to the left one increment. Such counters were used as odometers for bicycles and cars and in tape recorders and fuel dispensers and to control manufacturing processes. One of the largest manufacturers was the Veeder-Root company, and their name was often used for this type of counter.
Document 2: SWTPC: In the 1960s, many hobbyist electronics magazines such as "Popular Electronics" and "Radio-Electronics" published construction articles, for many of which the author would arrange for a company to provide a kit of parts to build the project. Daniel Meyer published several popular projects and successfully sold his kits. He soon started selling kits for other authors such as Don Lancaster and Louis Garner. Between 1967 and 1971 SWTPC sold kits for over 50 "Popular Electronics" articles. Most of these kits were intended for audio use, such as hi-fi, utility amplifiers, and test equipment such as a function generator based on the Intersil ICL8038.
Document 3: Acornsoft: Acornsoft was the software arm of Acorn Computers, and a major publisher of software for the BBC Micro and Acorn Electron. As well as games, it also produced a large number of educational titles, extra computer languages and business and utility packages – these included word processor "VIEW" and the spreadsheet "ViewSheet" supplied on ROM and cartridge for the BBC Micro/Acorn Electron and included as standard in the BBC Master and Acorn Business Computer.
Document 4: EDUC-8: The EDUC-8, pronounced "educate", was an early microcomputer kit published by Electronics Australia in a series of articles starting in August 1974 and continuing to August 1975. Electronics Australia initially believed that it was the first such kit, but later discovered that Radio-Electronics had just beaten it with their Mark-8 by one month. However, Electronics Australia staff believed that their TTL design was superior to the Mark-8, as it did not require the purchase of an expensive microprocessor chip.
Document 5: Acorn Atom: The Acorn Atom is a home computer made by Acorn Computers Ltd from 1980 to 1982, when it was replaced by the BBC Micro (originally "Proton").
Document 6: Disk Extended Color BASIC: Disk Extended Color Basic is an update to the Color BASIC interpreter for the Radio Shack/Tandy TRS-80 Color Computer series and is the default Basic interpreter, and therefore the de facto operating system, for the Color Computer 3. The Color Computer Basic implementations are somewhat different for the versions of Basic which come with the other family of TRS-80 machines, namely Basic Levels I, II, and III. Assemblers and Pascal and C compilers are available for the different machines in the series. Modified subsets of Color Basic may be found on many of the Radio Shack PC series of pocket computers (PC-1 to PC-4 by Sharp, PC-5, PC-6 to PC-8 by Casio) of the era.
Document 7: Poly-1: The Poly-1 was a desktop computer designed in New Zealand for educational use.
Document 8: Kenbak-1: The Kenbak-1 is considered by the Computer History Museum and the American Computer Museum to be the world's first "personal computer", invented by John V. Blankenbaker (1930-) of Kenbak Corporation in 1970, and first sold in early 1971. Only 50 machines were ever built. The system first sold for US$750. Today only 14 machines are believed to exist worldwide, in the hands of various collectors. Production of the Kenbak-1 stopped in 1973 as Kenbak failed, and was taken over by CTI Education Products, Inc. CTI rebranded the inventory and renamed it the H5050, though sales remained elusive.
Document 9: Digi-Comp I: The Digi-Comp I was a functioning, mechanical digital computer sold in kit form. It was originally manufactured from polystyrene parts by E.S.R., Inc. starting in 1963 and sold as an educational toy for US$4.99.
Document 10: Acorn Computers: Acorn Computers Ltd. was a British computer company established in Cambridge, England, in 1978. The company produced a number of computers which were especially popular in the UK, including the Acorn Electron and the Acorn Archimedes. Acorn's BBC Micro computer dominated the UK educational computer market during the 1980s. It is more known for its BBC Micro model B computer than for its other products.
Document 11: The Micro User: The Micro User (titled BBC Micro User in the first three issues) was a British specialist magazine catering to users of the BBC Microcomputer series, Acorn Electron, Acorn Archimedes and, to a limited extent, the Cambridge Z88. It had a comprehensive mix of reviews of games, application software, and the latest Acorn computers; type-in programs (duplicated on a "cover disk" which was available separately), a correspondence page offering help with computer problems, and approachable technical articles on programming and the BBC Micro's internals.
Document 12: Interact Home Computer: The Interact Home Computer is a rare, very early (1978) American home computer made by "Interact Electronics Inc" of Ann Arbor, Michigan. It sold under the name "interact Model One home computer". The original Ineract Model One computer was designed by Rick Barnich and Tim Anderson at 204 E. Washington in Ann Arbor, then moving to an office in Georgetown Mall on Packard St in Ann Arbor. Interact Electronics Inc was a privately held company that was funded by Hongiman, Miller, Swartz and Cohn...a lawyer firm out of Detroit. The President/Founder of Interact Electronics Inc was Ken Lochner, who was one of the original developers of the BASIC language based out of Dartmouth college. Ken had started Interact Electronics Inc after a successful startup known as ADP Cyphernetics, the original computer time share company in Ann Arbor, now known as ADP Network Services. Only a few thousand Interacts were sold before the company went bankrupt. Most were sold by the liquidator "Protecto Enterprizes" of Barrington, Illinois through mail order sales. The Interact Model One Home Computer debuted at the Consumer Electronics Show in Chicago in June 1978 at a price of $499. The majority of sales were thru Mail Order houses and you could buy it off the shelf at Highland Appliance in the Detroit, MI area and Newman Computer Exchange in Ann Arbor. Probably the most successful application available for the Interace was a program called "Message Center". With it, a store could type in whatever message they wanted to appear scrolling on a TV screen...like Advertisements, or welcoming messages to guests in an office. Although it was mostly a Game machine at the time with games such as Showdown, BlackJack and Chess, there was also BASIC programming where users could create their own programs in the BASIC computer language. Customers began hooking up Interact to control everything from lights in their house, to a Chevrolet Corvette!
Document 13: BBC Micro: The BBC Microcomputer System, or BBC Micro, is a series of microcomputers and associated peripherals designed and built by the Acorn Computer company for the "BBC Computer Literacy Project", operated by the British Broadcasting Corporation. Designed with an emphasis on education, it was notable for its ruggedness, expandability, and the quality of its operating system. An accompanying 1982 television series ""The Computer Programme"" featuring Chris Serle learning to use the machine was also broadcast on BBC 2.
Document 14: Extended Color BASIC: Extended Color Basic is an update to the Color BASIC interpreter for the Radio Shack/Tandy TRS-80 Color Computer series and is the default Basic interpreter, for the Color Computer 2. The Color Computer Basic implementations are somewhat different for the versions of Basic which come with the other family of TRS-80 machines, namely Basic Levels I, II, and III. Assemblers and Pascal and C compilers are available for the different machines in the series. Modified subsets of Color Basic may be found on many of the Radio Shack PC series of pocket computers (PC-1 to PC-4 by Sharp, PC-5, PC-6 to PC-8 by Casio) of the era.
Document 15: Acorn Electron: The Acorn Electron is a budget version of the BBC Micro educational/home computer made by Acorn Computers Ltd. It has 32 kilobytes of RAM, and its ROM includes BBC BASIC v2 along with its operating system.
