ZX Spectrum Next truly brings Speccy to the next millenium. Faster processor, expanded memory, sprites, advanced graphics modes etc. This book developed from my notes as I was learning these new technologies. As such, it can be used as a learning tool for beginner, but also as reference for advanced programmer.

The book is divided into three parts. First it looks into Zilog Z80, history, registers, flags, timing and interrupts and less know features like undocumented effects and instructions.

Second part is devoted to ZX Spectrum Next. It explains new technologies from perspective of assembler developer. Many are accompanied with example code or even fully working companion projects. Topics covered:

Ports
Memory Mapping
ULA
Layer 2
Tilemap
Sprites
Interrupts
Keyboard

The last part of the book lists all Z80 and Next extended instructions. It attempts to cover them from multiple perspectives: quick list with basic information, detailed list with descriptions, effects, timing tables and sorted lists of all variants with their hex opcodes.

Great natural exfoliation and keeps soap longer
Color: 2 Pack, Color: 2 Pack
I really like these Dewlavelle soap bags made from natural Egyptian loofah. They’re a simple idea, but they work really well in the shower. Just place your bar soap inside, wet it, and it creates a rich lather while gently exfoliating your skin. Pros: Natural loofah material gives great exfoliation without being too harsh Creates a nice, rich foam with bar soap Helps use up small leftover pieces of soap instead of wasting them Dries quickly between uses Long hanging loop makes it easy to hang in the shower Comes in a convenient 2-pack Cons: Texture may feel a little rough for very sensitive skin Needs to be rinsed and hung to dry to keep it fresh Overall, these are a great addition to a shower routine. They help your soap last longer and give your skin a nice exfoliating cleanse at the same time. Great value for a natural product.

Genius!! Clean and exfoliate!
Color: 2 Pack
I will tell you that this was a just looking find and I'm so happy I did. It's better than the rest of the fluffy stuff. It get to the real reason for bathing clean and exfoliate. Im able to insert my tallow all over body soap, suds right up, it doesnt tallow the soap to resolve and I can hang to my motorhome shower wall. I ordered one set and ordered a second soon after for my home shower. I recommend 💯!
