We offer this empty* AM29F040B FLASH ROM that can be used on a Harlequin 128 rev 2D board.
* We are not allowed to ship these chips with any Sinclair ROM on it, since that IP is owned by Comcast.
More info how to organise ROM images (up to 8) in this chip, is explained here:
You can program (flash) this chip on e.g. a MiniPro programmer.

A great top quality replacement for the 7805 5V 1A voltage regulator in ZX80, ZX81, ZX Spectrum 16K and 48K.
No heat, very power efficient.
As good as the Traco Power voltage regulators.
Pin compatible with the 7805.
Has a smaller footprint than the 7805, so fits at the location of the 7805 without any problem.
Offers the same power output as the standard 7805: 1A.
No heat, so no heatsink required.
Will increase the lifetime of your computer!
Photo shows the 7805 for reference as well:
Many ZX Spectrum enthusiasts would like to be able to experiment a bit with I/O connected to their computer.
This is your opportunity of doing just that!
All signals of the ZX Spectrum edge connector are available for you to wire to your own selection of parts to put on the breadboard (400 pins).
Included in this kit are:
On the board all signals that are available at the female pin headers, are printed in clear white text.
In the near future ByteDelight will offer some additional cool and fun easy project kits to interface to the ZX Spectrum, specially designed for this breadboard kit.
It’s very easy to damage the ZX Spectrum by making a mistake with the wiring.
Because this mouse will not fit in a letterbox, it has to be shipped as package, hence the increased shipments costs.
Combine shipment with other products from this webshop to save costs!
This offer is for a set of two replacement bridge rectifiers for an Opus Discovery floppy disk system.
We offer the high quality Vishay VS-2KBB20’s.
The Opus Discovery is an add-on made in 1985 for the ZX Spectrum – read more about the Opus Discovery here.
The original bridge rectifiers assembled from factory in a Opus Discovery system, are of poor quality.
With many users their Opus Discovery failed after adding a second Floppy disk drive, because the current drawn through these Bridge Rectifiers exceeded their maximum.
Many of the original bridge rectifiers bulge, and / or have visible melted plastic.
So it’s good as preventive maintenance of your Opus Discovery, to replace these bridge rectifiers.
If they fail, of course you will have to replace them anyway.
There aren’t many suitable replacement types available, hence we sourced them and offer them here.
The kit comes without assembly instructions, as they are straight forward enough:
Remove the old bridge rectifiers (using e.g. a tin sucker with your soldering iron) and install the new ones, minding the angled corner at one side of the bridge rectifiers for orientation.
Two of these will be in this replacement kit:
This offer is for a set of brand new replacement parts for the Opus Discovery floppy disk system:
– 2x replacement bridge rectifiers – Vishay VS-2KBB20
– 2x 4700uF (huge) radial capacitors 7.5mm pitch
– 2x 1uF 16V radial capacitors 2.54mm pitch
– 2x 10uF 16V radial capacitors 2.54mm pitch
– 1x 47uF 10V axial capacitor Vishay

Many of the original bridge rectifiers bulge, and / or have visible melted plastic.
So it’s good as preventive maintenance of your Opus Discovery, to replace these bridge rectifiers, and also the old original electrolytic capacitors.
The kit comes without assembly instructions, as they are straight forward enough:
Remove the old parts (using e.g. a tin sucker with your soldering iron) and install the new ones, minding orientation of the parts:
– the bridge rectifiers have one angled corner
– the capacitors have a ‘-‘ (negative polarity) side clearly shown on the casing

This offer is for an 8-pack stroopwafels including a nice Dutch tin can.
Some people seem to like these more than their ZX Spectrum goodies 😉
If you can’t get enough of these and you’re not satisfied with the mini’s I add to orders, get some of these!
