Bye Bye, Maplin

Well, that was quick. Four days ago we mentioned that the British electronics retail chain Maplin was being offered for sale, and today it has been announced that no buyer has been found and the company is going into administration.

We dealt with all the nostalgia for what was roughly a British equivalent to Radio Shack in our previous post. Perhaps now it’s time to look beyond the jumpers-for-goalposts reminiscences about spaceships on the catalogues for a moment, and consider what this means for us in 2018.

It’s fairly obvious that a retail model for selling either electronic tat or components is no longer viable in an age of online ordering and availability of almost anything at knock-down prices for anyone prepared to wait for a packet from China. This applies on both sides of the Atlantic, but for British retailers, the killer combination of very high rents and local business taxes makes it particularly difficult. Maplin were extremely convenient when you needed a part immediately, but the universal reaction from Hackaday readers was that they were overpriced. It’s the same story that has cleared away numerous chains in other sectors, and the toxic view that retail property is still the goldmine it might have been in decades past is largely responsible.

Despite all that, there must still be some demand for electronic components at a retail level even if the economics no longer support a showroom model. Perhaps a trade counter operation might have better luck, it will be interesting to see whether suppliers such as RS Components or CPC expand their networks to try to capture that business. Whatever happens, we’ll keep you posted.

Maplin For Sale

February 24, 2018 by Jenny List 78 Comments

If you are an American Electronics Enthusiast of a Certain Age, you will have misty-eyed reminiscences of the days when every shopping mall had a Radio Shack store. If you are a Brit, the name that will bring similar reminiscences to those Radio Shack ones from your American friends is Maplin. They may be less important to our community than they once would have been so this is a story from the financial pages; it has been announced that the Maplin chain is for sale.

Maplin started life as a small mail-order company supplying electronic parts, grew to become a large mail order company selling electronic parts, and them proceeded to a nationwide chain of stores occupying a similar niche to the one Radio Shack fitted into prior to their demise. They still sell electronic components, multimeters, and tools, but the bulk of their floor space is devoted to the more techy and hobbyist end of mass-market consumer electronics. As the competition from online retailers has intensified it is reported that the sale may be an attempt to avoid the company going into administration.

It’s fair to say that in our community they have something of a reputation of late for being not the cheapest source of parts, somewhere you go because you need something in a hurry rather than for a bargain. A friend of Hackaday remarked flippantly that the asking price for the company would be eleventy zillion pounds, which may provide some clues as to why custom hasn’t been so brisk. But for a period in the late 1970s through to the 1980s they were the only place for many of us to find parts, and their iconic catalogues with spaceships on their covers could be bought from the nationwide WH Smith newsagent chain alongside home computers such as the ZX Spectrum. It’s sad to say this, but if they did find themselves on the rocks we’d be sorry to see the name disappear, but we probably wouldn’t miss them in 2018.

One of the things Maplin were known for back in the day were their range of kits. We’ve shown you at least one in the past, this I/O port for a Sinclair ZX81.

Footnote: Does anyone still have any of the early Maplin catalogues with the spaceships on the cover? Ours perished decades ago, but we’d love to borrow one for a Retrotechtacular piece.

Sinclair I/O Board Completed Over 30 Years Later

November 21, 2016 by Jenny List 14 Comments

In the early 1980s when the 8-bit microcomputer boom was well under way, [Alan Faulds] was a student, and an owner of a Sinclair ZX81. He had ambitions to use it, in his words, “to control the world“, but since the Sinclair lacked an I/O port he was thwarted. He bought an expander board and a couple of I/O card PCBs from the British electronic supplier Maplin in the days when they were a mail order parts stockist rather than a chain of stores chasing Radio Shack’s vacated retail position.

Sadly for [Alan], he didn’t have the cash to buy all the parts to populate the boards, then the pressures of a final year at university intervened, and he never built those Maplin kits. They sat forgotten in their padded envelope for over three decades until a chance conversation with a friend reminded him of his unfinished student project. He sought it out, and set about recreating the board.

The ZX81 had a single port: a PCB edge connector at its rear that exposed all the Z80 processor’s lines. It was notorious for unreliability, as the tiniest vibration when a peripheral was connected would crash the machine. Maplin’s expansion system featured a backplane with a series of edge connector sockets, and cards with bare PCB edge connectors. Back in the 1980s it was easy to find edge connectors of the right size with the appropriate key installed, but not these days. [Alan] had to make one himself for his build.

The I/O card with its 8255 and brace of 74 series chips was a double-sided affair with vias made through the use of little snap-off hand-soldered pins. [Alan] put his ICs in sockets, a sensible choice given that when he powered it up he found he’d put a couple of the 74 chips in the wrong positions. With that error rectified the board worked exactly as it should, giving the little ZX three I/O ports, albeit with one of them a buffered output.

We haven’t featured the little Sinclair micro as often as we should have here at Hackaday, it seems to have been overshadowed by its ZX Spectrum successor. We did show you a VGA ZX81 emulated on an mbed though, and a rather neat color video hack for its Brazilian cousin.
