A lot of GitLab pages links and Git pushing a relatively large commit to GitLab: “error: RPC failed; HTTP 502 curl 22 The requested URL returned error: 502”

Posted by jpluimers on 2026/05/27

Got an error when pushing a relatively large commit to GitLab: error: RPC failed; HTTP 502 curl 22 The requested URL returned error: 502

There was no big difference in information between these commands¹:

  1. git push
  2. git push --verbose

Screenshot of Pitfall II: Lost Caverns (Apple II, 1984) – MobyGames

[Wayback/A] Screenshot of Pitfall II: Lost Caverns (Apple II, 1984) – MobyGames

Pitfall II: Lost Caverns (Apple II) screenshot:Title screen (this version has been cracked)

Memories of Apple II, ][e and //c.

There was quite a good crack-scene in The Netherlands with a well known name “The Redhead”.

Back then I didn’t know about the BBS systems involved:

  • NEABBBS: 020-717666 (which was ran by Max Keizer and part of FidoNet)
  • NABBS: 03200-28717 (which I could hardly find any other information about, the areacode was part of Lelystad)

dasm – macro assembler for 8-bit machines

Posted by jpluimers on 2026/03/04

Finding a reference to DASM while researching yesterday’s post @jpluimers on Twitter: “@b0rk @jilles_com Acids vs bases.”, it felt even more like a trip like memory lane as I had used it in the 1980s on Apple ][ and Apple //e after mainly using EDASM. Lisa and Merlin.

I am glad that it is still alive and kicking with home page at [Wayback/Archive] dasm – macro assembler for 8-bit machines and repository at [Wayback/Archive] dasm-assembler/dasm: Macro assembler with support for several 8-bit microprocessors.

Especially this history section on the home page rang a bell:

  • Matthew Dillon started dasm in 1987-1988.
  • Olaf “Rhialto” Seibert extended dasm in 1995.
  • Andrew “Dr.Boo” Davie maintained dasm in 2003-2008.
  • Peter Fröhlich maintained dasm in 2008-2015.
  • In 2019, the dasm source code and releases were moved to GitHub.

Apple II: Single Step in Monitor | Applefritter

Posted by jpluimers on 2026/02/10

I need to check out which ROM my Apple //e and //c have as per [Wayback/Archive] Single Step in Monitor | Applefritter comment by [Wayback/Archive] jeffmazur | Applefritter:

Depends upon which machine and ROM version you have.

The original Apple II monitor does have an S command to single step code in the Monitor. That was removed however to add other features and was not restored until ROM00 of the //c. There are however various 3rd-party ROM images that also have the Step and Trace commands, for example ROMeX and ROM4X, APPLEII.EDM, etc.

There are also hardware boards available to do this as well

Bit by Bit – Exploring Low-Level Programming on the Apple IIe | decuser’s blog

Posted by jpluimers on 2026/02/05

At the time of posting [Wayback/Archive] Bit by Bit – Exploring Low-Level Programming on the Apple IIe | decuser’s blog in 20251010, four episodes were up at [Wayback/Archive] Bit by Bit – Exploring low-level programming with an Apple IIe – YouTube which at the time of archiving at the end of October 2025 already got 10 episodes.

Hopefully by now – some 2 months later – the list has grown even further.

More Apple ][*, //* II* and classic Macintosh hardware upgrades

Posted by jpluimers on 2025/11/14

The mini micro classic Apple emulators related post last week became way too big, so here is the classic Apple 2/Macintosh hardware upgrade part follow-up I announced in Some notes on mini/micro Apple //e emulators.

Last week, I mentioned [Wayback/Archive] ARC Javmaster – YouTube. Let’s continue from there for an even bigger post (:

Javmaster actually has a shop at [Wayback/Archive] Welcome to the 8-bit stuff store – 8 bit stuff cool retro computer 3D gadgets and geekery with a lot of interesting (mainly Apple ][ era related) retro things like:

30+ years of Apple’s Human Interface Guidelines from 1985 (and earlier Lisa / Apple II equivalents)

Posted by jpluimers on 2025/09/25

I hope someone has also archived all these in the Internet Archive as this is a great collection of historic material: [WaybackSave/Archive] GitHub – gingerbeardman/apple-human-interface-guidelines: Apple Human Interface Guidelines, et al.

If you have more of them: add them via a pull-request.

Related: [Wayback/Archive] Making It Macintosh: The Macintosh Human Interface Guidelines Companion : Apple : Free Download, Borrow, and Streaming : Internet Archive

A client that went belly up in the early 1990s had all these and similar books. In retrospect, I though have found a way to obtain them but back then I didn’t value the uniqueness of them enough and didn’t have the storage space for it (I lived in a 30m² apartment).

Welcome to #AprilApples! Apple II Computer event celebrated in the month of April

Posted by jpluimers on 2025/04/01

AprilApples Apple II Computer Event LogoLast year, #Appril][ got rebranded into #AprilApples, so I wish you a happy retro-month filled with April Apples!

[Wayback/Archive] Welcome to #AprilApples! Apple II Computer event celebrated in the month of April

Consider using the [Wayback/Archive] #AprilApples Style Guide with logon on the right, plus Garamond and/or Motter Tektura typeface when possible to really give tribute to the Apple ][ era.

Last year, a big surprise was that Apple Computer put a PDF version of the famous Apple Pascal Poster on the Internet Archive.

So today is a great day to give that more traction and link to it:

A year before, during April][, a remake of that poster got done on AppleFritter: Home[Wayback/Archive] Apple pascal poster, remade | Applefritter

Some notes on mini/micro Apple //e emulators

Posted by jpluimers on 2025/01/30

Retro computing is wildly popular, and with the rise of low cost single-board computers (SBCs for short), both Apple //e and ][+ emulators plus extension cards have proliferated,  based on Raspberry Pi (or even their RP2040 microcontroller based Pico), ESP32 or predecessor ESP8266 microcontrollers and others.

Some links for my archive:
