Send me an email RobManuel@gmail.com and I'll put you in touch with publisher on how to stock it. (It's very good btw! I mean I would say that, but it's not a dashed off cash-in for the obviously fantastically lucrative ZX81 market, it's six months work and a work of love)

The only legit way to make games is in your parents' basement on a ZX Spectrum or Commodore 64. Apple II is a marginal case and you should consider upgrading by 2030.

making games so you can hopefully afford to make more games is literally a different industry from grinding up people so number goes up and it is harmful to pretend otherwise regardless of whether or not we share a platform or a binary format

Someone can grab a bargain today. Reduced the price for the last one further. 😆

Ever had a problem loading programs into a ZX81 or ZX Spectrum using a stereo 3.5mm jack? This may be why. Look at the photos, the jack sockets connect to the tip and the ring, not the sleeve. That's fine for a mono TS jack, but a stereo TRS jack connects to left and right, no connection to ground.

New blog post - Loading programs into the Timex Sinclair TS1500 - blog.tynemouthsoftware.co.uk/2026/10/load... Some unexpected issues with tape loading, and yes, you can indeed use the Minstrel ZXpand II to load from SD card.

The ZX Spectrum's attribute clash wasn't a bug. It was a feature that the hardware designers hadn't fully thought through, which Sinclair's marketing department promptly turned into a game design design challenge.

Found it! Check out the wobbly constructions pictured on the back of the box. Things were already dicey when the printer was also attached, so I can’t imagine those

Sinclair Research would like to inform you that the ZX Spectrum's rubber keys have been designed to last approximately three months of enthusiastic typing. Please contact us if yours have survived longer — we'd like to run them through our laboratory. Probably for science.

The fun of #ZXSpectrum magazine covertapes. I found a small selection in a charity shop this week. There were a few I'd have been interested in to fill some gaps but the tape in every cassette there showed signs of mould.

The gap between ordering a Sinclair computer by mail order and receiving it was typically six to eight weeks. Six to eight weeks of checking the post every morning. Six to eight weeks of reading computer magazines. By the time the computer showed up, you already knew BASIC. The delay was the

Sinclair Research would like to clarify that the ZX Spectrum is not a toy. It is a serious business computer that happens to be the same size as a paperback novel, costs less than a bicycle, and is used almost exclusively by children to play Horace Goes Skiing.

Andesite, our ZX Spectrum Next emulator, has been getting an accuracy pass. The latest work brings compatibility with more demanding Next software. Here's Atic Atac for the Next running on Andesite. #ZXSpectrumNext #Emulation

Well, there is the Commodore PET in 40 or 80 column, ZX80, ZX81, Jupiter Ace. Lots of choice there and some new challenges.

Heavy footsteps was enough to trigger the ZX81 wobble crash in our household. Such was its associated experience with the computer, the EightyOne and iOS/iPadOS/watchOS emulators have an option to relive the pain.

Who else learned what "volatile memory" meant not from a textbook, but from accidentally kicking the power cable out of the wall and losing three hours of work? Or a wobble? The ZX81 taught computer science through trauma. It was surprisingly effective.

Was unpacking some books this morning and somehow I missed this one when I bought a Timex Sinclair 1000 a couple years ago. It’s got a comic book adventure and when the big fight comes, you write a BASIC game included in the back. Neat!

The Sinclair ZX Spectrum was available in two colours: black with a rainbow stripe, or a rainbow stripe with black. Sir Clive believed in giving customers choice, provided all choices were identical. Well, ok, 16 or 48K

Remember that Nine Tiles struggled to squeeze everything in the 8 K ROM, including floating point.

You could always spot someone who learned basic on a Sinclair machine as they spelled GOTO as two words: "GO TO"
