With the permission of Adobe Systems Inc., the Computer History Museum is pleased to make available, for non-commercial use, the source code to the 1990 version 1.0.1 of Photoshop. All the code is here with the exception of the MacApp applications library that was licensed from Apple. There are 179 files in the zipped folder, comprising about 128,000 lines of mostly uncommented but well-structured code. By line count, about 75% of the code is in Pascal, about 15% is in 68000 assembler language, and the rest is data of various sorts.

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:

This post covers some topics around one of the retro machines I have. They helped me form some thoughts on additions I might want to add to mine.

Needs a Raspberry Pi, but looks very interesting.
256 shades of grey
Back in 2022, someone started doing an amazing thing: reverse engineering and rebuilding a 256-grey/color video card for the Macintosh SE/30 PDS (Processor Direct Slot).
A very interesting start of a long journey with the result that a few people could actually play around with it. Hopefully by now more have been produced, but be aware: this is a hobby of the designer, so unlike some other hardware: do not expect high numbers of these boards to become available.
Long thread in – for now – 14 pages of which I think below are the most important excerpts:

A while ago, This does not compute had a few nice videos on a Mac SE/30 and it’s repair, including the recap process of replacing the electrolytic capacitors (or condensators in some other languages), and cleaning the board (some wash it with hot water and soap, others with isopropyl-alcohol, often called rubbing alcohol).
Note the simasimac can have many causes: bad capacitors in main board are the most common, but it can also be bad memory.
White lithium grease can make the floppy work again (see also [WayBack] Lithium soap – Wikipedia and [WayBack] Grease (lubricant) – Wikipedia).
He also added some links to which I added some quotes and WayBack links:

The Mac ROM-inator II replaces the stock Macintosh ROM SIMM with a custom flash memory module. Add a bootable ROM disk, make your system 32-bit clean, gain HD20 hard disk support, and more. The Mac ROM-inator II supports the Macintosh SE/30, IIx, IIcx, IIci, IIfx, and IIsi.
The Mac ROM-inator II is fully assembled and ready to use. Just plug it in and go.

2 MB SIMM pre-programmed with ROM Disk with System 7.1, HDSC Setup, ResEdit, and SCSI Probe. Compatible with Mac SE/30, IIx, IIcx, IIci, IIfx, IIsi. More InfoThe Mac ROM-inator II is great for breathing new life into your old SE/30 or II-series Macintosh. The ROM disk provides fast and convenient boot-ups and a collection of disk utility programs, and customized startup sounds and icons add a touch of fun. The ROM SIMM comes pre-programmed with a BMOW-made custom ROM containing the following changes:
- ROM disk provides a diskless booting option
- HD20 hard disk support built-in
- 32-bit clean – allows use of System 7.6+ and more than 8MB RAM
- Memory test is disabled for faster booting on 16MB+ systems
- Customized startup chime – major 9th arpeggio
- Happy Mac icon is replaced by a color smiling “pirate” Mac
- New startup menu screen displays installed RAM, addressing mode, and ROM disk details
The ROM-inator II is based on Doug Brown’s earlier [WayBack] Mac ROM SIMM design, used with permission.

The SE/30 is probably the most popular candidate for recapping. Unfortunately, it’s also one of the more difficult to revive as the leaked electrolyte easily damages traces and vias on these boards. Be sure to wash these boards very well and inspect closely for broken or rotten traces.

Notes
Desolder can be tricky, especially for surface mount. This helps:
- Add some fresh 60/40 solder to the joints with a solder gun (as modern solder is lead free, whereas past solder contained lead)
- Carefully heat up the component and surrounding area with a heat-gun
Choosing capacitors:
Soldering: always add some fresh solder on the pads before soldering surface mount (SMD) capacitors.

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:

From a while back: [WayBack] Open Apple #66 (December 2016) : Glenda “The Atom” Adams | Open Apple
This month on Open Apple, we sit down with Glenda Adams, better known on the Apple II as The Atom. She was a cracker of some note back in the 1980s, and she shares great stories with us…
It reminded me of the days I started to learn programming. Good memories. @glenda_atom was way ahead of me (:
