Cool: Apple mini-assembler found inside Woz’ monitor inside Apple II Integer Basic

Posted by jpluimers on 2021/01/18

From a while back: [WayBack] This week, a mini-demo of the mini-assembler found inside Woz’ monitor inside Apple II Integer Basic. CALL –151 F666G … – mos6502 – Google+

This week, a mini-demo of the mini-assembler found inside Woz’ monitor inside Apple II Integer Basic.
CALL –151
F666G
You can find reconstructed sources in Jeff Tranter’s repo here:
https://github.com/jefftranter/6502/tree/master/asm/Apple%5D%5BMonitor
where we see credits to Steve Wozniak and Allen Baum. But in this oral history it seems the assembler was Baum’s work:
“Baum: So it was brute force, very simple and fit into 256 bytes if you already had the 256-byte disassembler.”

Anyhow, one page of code – or two – is very impressive!

For more info, try searching for F666G! (We wonder at this memorable address – the Apple I price was $666.)

Computing History – The UK Computer Museum – Cambridge

Posted by jpluimers on 2020/06/19

On my places to visit:

The Centre for Computing History is a computer museum based in Cambridge, UK. With a collection of vintage computers and game consoles, many of the exhibits are hands on and interactive.

[WayBackComputing History – The UK Computer Museum – Cambridge.

When I bumped into it, this was their collection size, ranging from the 1960s until recent history:

Archive Statistics :

  • Computers = 993
  • Peripherals = 1446
  • Mobile Devices = 31
  • Game Consoles = 213
  • Video Games = 10259
  • Software Packages = 2605
  • Books = 2045
  • Manuals = 4106
  • Magazines = 9057

Looking at their archived brands (having [WayBack] MITS – Altair and [WayBack] Raspberry Pi in the collection) is such a joy.

Archiving the older parts is a tough job, as they stem from way before the web era, so information has been lost, parts are hard to source, a lot of hardware got thrown away or is hard to find at all, people have died. More on that at [WayBack] About – Computing History.

Without a physical visit, you can find what they have at [WayBack] Search Our Archive – Computing History.

The video below on their archive is impressive.

Apple@40: happy birthday!

Posted by jpluimers on 2016/04/01

Apple Inc. just turned 40 today. Happy birthday!

Based on Mac@30, here is my educated guess for Apple@40.

(Boy what were they thinking when establishing Apple Computer Inc. on April 1st 1976)
