Show HN: 8Bit Computers Book

[daitangio]

Hi everybody! Due to Covid 19 pandemic I was forced in my home, so I revamped my book

https://8bit.gioorgi.com

It is a huge collection of information about the 8bit comnputer era (1980-1985) up to the NES console. I collected information from various source including “The 8bit Guy” videos and specific site (like C64 wiki, nesdev etc).

I am using docusaurus to give a pleasnt look to the whole site.

Please give me you feedback (and happy new year btw)!

I really like this site, it’s a blast for me. Please keep at it as this stuff deserves to be remembered.

I realise the book is still in draft and so open to change but it might be worth noting that in its current form you’re only covering the American 8-bit market.

To my European eyes it looks weird to talk about the 8-bit scene and not mention Acorn BBC Micro, Sinclair and compatibles or Amstrad.

I can also see the abscess of MSX references.

That’s fine if that’s the goal but does leave out a lot of world changing developments.

E.g. the design of the BBC Micro led to the design of the first Arm processor.

Running BBC BASIC at the speed of 6502 assembler was one of its design goals.

To my American eyes, it’s missing one of the three “Trinity” machines: the TRS-80 and all its descendants. It’s also exclusively focused on the 6502, rather than the 6800, 6809, Z80, 8008…

Yes, the different CPUs added a richness to this time period readers are very likely to find enjoyable as well as enlightening.

Ahhh, the 6809! It's my favorite 8 bit CPU. If you've not given it a look, please reconsider. You are likely to benefit too. That chip is beautiful, and is a whole lot more powerful and elegant than one might expect an 8 bit CPU to be.

Let me seed the content a little: (and the 6800 too, because why not?)

Williams "DEFENDER" runs on a 6809 at 1Mhz, no blitter, no tiles, just a straight up bitmapped display. Here's a tutorial video with an expert player and a new gamer being introduced to the game. Lots of gems in their chatter and a good look at what an 8 bit CPU can really do:

Fun fact: DEFENDER plays one sound at a time, and the sound board is a 6800 (also a good CPU and missing from the list) connected right to a DAC to generate sound procedurally. Williams has a distinctive sound in all their classic games, and this board is why.

Amazingly, DEFENDER was ported to the Color Computer 3, the sound board replaced with samples. Doing that worked better than I thought it might, and overall the game play is on point. This port impresses me because of how different the frame buffer RAM layout is, and the 6809 being flexible enough in it's many addressing modes appears to manage in both scenarios. Very little is lost.

I hope to see one of the better players run the port, and or play it myself on a system one day soon.

Here's a system I've always wanted: http://www.oldcomputers.net/swtpc-s09.html

It's an 8bit workstation! 768K of RAM, nice storage, respectable terminal, expandable...

https://www.youtube.com/watch?v=jLdAvNj8HNI

They made respectable machines using both the 6800 and 6809 chips.

The 6800 ended up in wonderful Tektronix computers and terminals. The computer was industrial, and intended for prototyping, science and industrial control and not commonly known. https://www.primidi.com/motorola_6800/personal_computers

The terminals were well known, high resolution vector, and wait for it...

CRT STORAGE TUBE displays! These delivered "4k" vector graphics in the 70's! The catch? No refresh cycles on the displays. Instead of blasting through all the vectors X times per second, these CRT displays would continue to glow, until erased for a new screen display.

The 4051 came with tape, X,Y analog joystick or dials, keyboard, display, and serial ports, and a very powerful "BASIC" that had a strong emphasis on math and graphics. I used this system to program CNC machines back in the day, and what could be done in BASIC on one was impressive.

Check out the demo set. These displays are beautiful and functional.

It's a huge topic. It misses important American stuff too. For example, no mention of the third member of the 1977 Trinity--the TRS-80 (although the CoCo is mentioned in the Commodore section).

But very nice for what it does cover!

EDIT: sibling comment just beat me by a couple minutes to mentioning the Trinity. :-)

> abscess of MSX references

Doh! \blush Cheers Apple.

[flatiron → Lio]

Oy! What about me speccy!

[Lio → flatiron]

I thought I'd covered that with Sinclair and compatibles ;)

I'm actually more ashamed I missed off interesting stuff from Tulip, Dragon, Grundy, RM, Minitel and a whole host of others.

While that looks good as far as it goes,it is incomplete as it leaves out the 8080/Z80 and 680x worlds of the 1970s-80s, along with the main disk-based OSs of that period (mainly CP/M).

Well done.

[jjav → simonblack]

The 6809 rocked, particularly when paired with OS-9.

[donio]

I know you gotta start somewhere but just Apple and Commodore is a very narrow focus. There was so much more out there.

[timbit42 → donio]

Yes, now add: MSX, Sinclair ZX Spectrum, Atari 8-bit computers, Amstrad CPC, Acorn BBC Micro, Tandy Color Computer, Tandy TRS-80.

Electronic Dreams is a great book for a British perspective - https://www.goodreads.com/book/show/25663666-electronic-drea...

Contains a few pearls...

> Commodore licensed BASIC from Microsoft on a "pay once, no royalties" basis after Jack Tramiel turned down Bill Gates' offer of a $3 per unit fee, stating, "I'm already married"

In this section, "6510." (presumably) got converted into an empty numbered list item: https://8bit.gioorgi.com/docs/8bit/commodore64#65536-bytes-o...

This era in computing is hot right now. Lots of us remembering, sharing our stories and the more the merrier, in my view.

I like that you are including current information and efforts, such as "A Mind is Born" demo production. Cool.

[sedan_baklazhan]

Looks interesting, thanks! Any chance of providing a PDF file for download?

[jbverschoor]

MSX?

[sds333]

very cool thanks
