RS232 Serial Wifi Modem for Vintage Computers V4[Wayback/Archive] RS232 Serial Wifi Modem for Vintage Computers V4 from The Old Net on Tindie

Get your vintage computer connected to BBS’s and more! It can act as a Modem, PPP ISP or a SLIP Ethernet adapter!

Via [Wayback/Archive] Jilles Groenendijk on Twitter: “RS232 Serial Wifi Modem for Vintage Computers V4 from The Old Net on Tindie”

In the mean time, more videos on it have appeared, for instance from [Wayback/Archive] Action Retro – YouTube:

  1. [Wayback/Archive] Easy WiFi for Vintage Macs with TheOldNet Serial WiFi Modem – YouTube (Action Retro seems to have a zip-tie fetish; I’d prefer Velcro which is actually a 1940s Swiss invention, contrary to the 1960s NASA invention many still think it is)
  2. [Wayback/Archive] Best Option for Apple ][ Modern Networking? – YouTube

Of these last two videos, the first also linked to this picture of converter tables, including 9-pin D-sub RS-232 to mini-DIN-8 apple serial (which could be switched between RS-232 and RS-422 mode): [Wayback/Archive] upload_4705.png (880×1874). It is referenced only from a few places:

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

[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

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:

Some links on the Apple IIc Plus (Apple IIc + on the boot screen) likely the rarest from the Apple II series

Posted by jpluimers on 2025/05/16

A while ago I bumped into this video about likely the rarest model in the Apple II series: the Apple IIc Plus:

[Wayback/Archive] Apple IIc Plus – the rarest and fastest Apple II! – YouTube

Returning to one of my favorite subjects – the Apple II – I decide to finally repair a broken Apple IIc Plus gifted to me a little more than a year ago. This machine was the final true hardware revision to the Apple II line, coming in 1988, and the last standalone machine in the line released. It was also the fastest, with a 4Mhz CPU (vs. 1Mhz in most other Apple II’s, and 2.6Mhz in the IIGS). But it was a problematic machine for Apple, with a concept that had been watered down to the point of, well, pointlessness.

The market wanted it even less than it wanted the original IIc (which was my first computer – the one in the thumbnail is my original machine). Still, it is an interesting computer for its accelerated CPU, and its somewhat anachronistic nature at the time of its launch.

It has a cool demo of Flight Simulator II demo mode (which back in those days crashing the plane – demo modes luckily improved from there :) at both 1 Mhz and 4 Mhz. It indeed is not smooth, but a lot faster.

The problem back in those days with acceleration is it would not just improve render speed, but also increase clock time speed. It made most games almost impossible to play in accelerated mode.

If I ever get one, I need to replace the 110V power supply with a 240V/110V auto-switching one as per [Wayback/Archive] IIc + 240v Power:

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
