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.)

Posted by jpluimers on 2020/05/28

[WayBack] GitHub – dschmenk/apple2pi: Apple II client/server for Raspberry Pi: hybrid computer of a Raspberry Pi inside an Apple II (either ][, or ][+, or //e) so the Apple II can be a front-end to the Raspberry Pi which then can run an Apple IIGS emulator, talk to the Apple II storage hardware and much more.

It can run [WayBack] RASPPLE II: A2CLOUD, A2SERVER, Apple II Pi for Raspberry Pi

Two fans were podcasting at RetroMacCast before it was cool

Posted by jpluimers on 2018/08/07

Around this time, episode 500 of RetroMacCast should be out.

It’s an “about weekly” podcast centered around classic Apple computers, mainly of the Macintosh kind but occasionally also on the Apple I, ][, //e, //c and ///, IIgs and Lisa kinds.

After all these years since they started in 2006, It’s still fun to listen to.

Occasionally they do a vodcast on YouTube, for instance their 100th show below.

New episodes are announced here:
