The Plus 3 is a self contained disc interface and 3.5 single sized disc drive providing the user with over 300 Kbytes of storage and the new powerful advanced Disc Filing System (ADFS). ADFS provides easy to use facilities at the Basic level but also has features making it ideal for business use...\
|
||
...A second expansion socket on the Plus 3 allows the connection of a further disc drive, this can be either 3.5 inch or 5.25 inch.

|
||
subtitle: ''
|

text: |-
|
||
The Electron computer was conceived as a minimal and economical machine largely based on the BBC model B, a kind of cut down version in fact. Sadly, the lack of basic interfaces such as Centronics or Serial, effectively deterred a lot of potential buyers from buying the Electron, which dangerously slowed down the sales of the system.\
|
||
Acorn’s answer was the 'Plus 1' interface, which offered a Parallel Centronics printer interface, analogue joystick connector and two cartridge slots. The extension connected to the expansion port of the Electron and screwed into the case, to lock in place. With the "Plus 1", the Electron could then offer a decent range of interfaces matching the flexibility of its competitors, while still preserving an attractive price along with its own unique qualities (excellent BASIC and good graphic capabilities).\
|
||
Unfortunately, the "Plus 1" Interface was not enough to boost the sales in Europe.

**(1)** The AcornSoft company produced several programs on cartridges, mainly games\
|
||
**(2)** Cartridge slots can also receive hardware expansions made by Acorn or other independent companies\
|
||
**(3)** Expansion connector handling data transfers between the Electron and the expansion modules\
|
||
(4) Parallel Centronics interface, compatible with a large range of printers\
|
||
(5) This joystick connector is also a true analogue / digital port which can be connected to measuring instruments

|

|

text: |-
|
||
A disk drive unit suited to the performance of the Electron was lacking to make it a coherent and successful system, able to face the competition.\
|
||
The "Plus 3" interface cleverly fulfilled this need. L-shaped, it connected at the rear of the Electron, still allowing the addition of the "Plus 1" interface or any other expansion... The whole thing was firmly fixed to the case and could be moved without fear of damage.

|
||
**(1)** The interface has ROMs holding an additional set of BASIC instructions for the operating system for file management. The electronic part also contains logical circuits acting as a disk-drive controller\
|
||
**(2)** This connector allows connection of a second disk drive which can be of a different format to the first one. An adapter also permits use of this connector to control other peripherals\
|
||
**(3)** The disk drive is 3.5". The storage capacity is 320 KB, single-sided. Each side is divided into 80 tracks composed of 16 sectors, which can hold 256 bytes each\
|
||
**(4)** The interface clips firmly to the Electron, which allows the whole set to be carried safely\
|
||
**(5/6)** The connector of the Electron also allows the transfer of information to other peripherals, such as the "Plus 1" interface.

The disk operating system of the Electron was called ADFS for "Advanced Disk Filing System".\
|
||
It was a powerful and modern operating system, offering numerous capabilities usually only found on big systems : hierarchical directories, file access controls etc. It was delivered with a detailed user manual and a floppy disk containing numerous utilities and sample software.

text: I loved this machine. I bought one in 1985 when it got dumped on the market. It costed me fl 100,$ (appr. 45 euro). Bought some games too (Androids!). Later on I bought the Plus 1 and a double-density 5,25" drive! A new world opened up to me. With the RAM extension, you could load programs into the upper memory, like Pascal. And program the RAM with your on boot loaders. I have programmed a lot (VDU codes!). I frequently bought the Electron User magazine, and type the code from the magazine. When I moved to my current house in 2005 I gave the Electron away to a friend.

I loved the Acorn Electron. It was my first PC in approx. 1987. A BBC compatible so cheap BBC games from the poxy games shop in Southend,..most worked. I used to start loading the game and then have dinner while waiting!!.. It was pretty great at the time, before games consoles $ game boy.\
|
||
Even wrote some games out of the manual.\
|
||
It was about that time that Commodore64s came along which ROCKED! Thanks Barry Taylor for the C64!\
|
||
It was 20 pounds well spent!

I was 14 years old when the Electron appeared and i begged my dad for one i belive they cost 299 even in 1983 that was a lot of money.\
|
||
I used to buy the magazines and type in programs, i bought many games for it one of my memories is of a game called Citadel , one thing i do remember is borowwing games off BBC owning freinds and finding\
|
||
the Electron couldnt run some, think it was a graphics issue\
|
||
I have very fond memorys of that machine i held on to it until 2007 when i moved to canada, i gave it to a freind and it was still working.\
|
||
I also remember the powersupply issues i was on my second when i gave it away.

text: I got hold of an electron a while back (restored it, seen on my website). I have a real soft spot for the electron. It was underpowered but still a very caperble machine. A good programmer could do magic with this machine and its a shame that the ULA took so long to develop.

i loved my lil electron, i still have it up in loft at mums and used it about a year ago, since then im using an emulator to relive old days of the classic games.
|
||
|
||
i find it amazing that even now - acorn technology is still in use - i only just found out that most mobiles use what is essentially an acorn chip -
|
||
|
||
brilliant computer - right gear - just a little bit too late
|
||
|
||
i did get a spectrum eventually and i hated it - if i could get hold of a BEEB id use that too

text: Many older PC video cards like my Hauppage Brand card can be set to NTSC, PAL and SECAM analog standards as well as being switchable to the appropriate Channel / Frequency table. Having a monitor with a refresh rate of at least 50 Hz will also be a BIG help. If it hooked into a common TV set (UK or USA), you SHOULD be able to hook it to a decent, if not older, video card.

text: I loved my little Electron. I learned to program on it, played loads of games Elite!!, Repton, too many to mention. It was a great little computer with a really nice keyboard, much easier to use than the Spectrum rubber keys. I sometimes think about buying another one now but maybe the memories are best left alone. (Power sockets and bricks were a problem though.)

text: Two common problems with the power supply on these machines; the PSU itself tended to run hot and die, and the PCB mounted power supply socket used to disconnect from the solder connections and/or print on the PCB, as there was no strain relief.

Hi.
|
||
|
||
I have 2 Acorn electrons but neither of them are working. In my opinion the little gems are too good to go to scrap so I was wondering if anyone would be able to help with the repairing of these.
|
||
|
||
Basically they both seem to have the same problem apart from a slight difference. When I turn them on, one has a totally white screen, and the other a totally yellow screen. There is no BEEP like you normally get.
|
||
|
||
Any ideas??? please email me with any feedback. Thanks
|
||
|
||
Tom

The Acorn Electron is basically a cut-down version of the [Acorn BBC-B](/museum/acorn-computer-bbc-model-a-b-b/) with which it is partly compatible. After the success of the [BBC](/museum/acorn-computer-bbc-model-a-b-b/), Acorn and founder Chris Cury wanted a product to compete with "under £200" computers and especially with the [Sinclair Spectrum](/museum/sinclair-zx-spectrum/), its main threat. But sadly, Acorn failed to meet the demand for the new system, mainly because of production problems related to the large custom ULA at the heart of the Electron.
|
||
|
||
The next year (1984), Acorn decided to anticipate all these problems and focused on producing the Electron in vast numbers. But unfortunately, public demand and enthusiasm were on the wane, and despite an extensive £4-million advertising campaign, a third of the Electrons that were built never made it to the shelves, leaving behind large stockpiles of components that had been paid for but were never used.
|
||
|
||
Compared to the BBC and its flexible connectivity, the Electron was quite basic with only one expansion port to play around with. Fortunately, Acorn quickly released the Plus 1 expansion offering two ROM cartridge slots, a parallel / centronics interface and a joystick connector.
|
||
|
||
The built-in Acorn Electron BASIC, largely derived from the famous BBC BASIC, was impressive with innovative features such as the ability to define real procedures with DEF PROC and ENDPROC, or the handling of error events (in 1983 !). There was even an OLD statement which would recover a program erased by NEW. A complete assembler language was also stored in the 32K ROM.
|
||
|
||
The graphics capabilities were also quite impressive for a computer of this category. Text mode of up to 80 columns and a high resolution of up to 640 x 256 pixels with 2 colors. The custom ULA developed especially for the Electron handled the video display, sound and I/O communications! This was the real heart of the Electron.
|
||
|
||
The mechanical keyboard was very good. BASIC statements were printed on most of the keys, allowing users to type them in one go. A small amber LED placed on the left part of the keyboard indicated if you were in lowercase or uppercase mode.
|
||
|
||
Despite being more powerful than the ZX Spectrum, the Electron didn't sell well and suffered from a lack of certain software.
