CD-ROMs and only 128k of RAM? Sorry, that doesn't pass the smell test. Once CD-ROMs were available, 2-digit megabytes of RAM were standard (and affordable) for home PCs.

An Apple IIc with an Apple II SCSI interface card will happily utilise the 1989 AppleCD SC. Apple IIgs maxed out at 8mb RAM or so; with only 128kb out of the box for the IIc for example.

CD-ROMs were outselling all other audio formats in the United States by 1991 for context.

I started programming in 1977/78 in CBM/PET Basic on a Commodore PET 2001 with cassette tape drive and 32k upgrade. I loved those days. My parents didn't understand what the deal was with the costly computer I saved up for at age 13, and why I thought it was so important. It also required many late hours on my part on school nights. I moved on to assembler and C and many other languages over the years. I had a renaissance for the low-level and small thanks to you. Oscar, I worked through your, "Programming Boot Sector Games" with much joy. Your books and writing have brought back some of that nostalgia and fun for me, so thank you for that, and keep it going! It's also resharpened some dead areas and gaps I have sustained from the multiple abstraction layers of today's modern software world.

Earlier quoted context omitted.

Pretty sure the ZX Spectrum (also 128k) had some kind of CDROM adaptor, it worked via the joystick port IIRC. A quick google didn’t tell me anything so maybe I imagined it.

I think you did imagine it, yes. The Spectrum did not have 128kB until near the end of its life. It started out with a choice of 16kB or 48kB and that was all you got until 1986. It also didn't have a joystick port. Nor did it have floppy disks (although 3rd party interfaces existed). Amstrad added joystick ports when it bought the product line and brand from Sinclair Research, soon after Sinclair launched the Spectr…

Yeah, it was definitely in the Amstrad era, not the rubber keyboard. Spectrum +2 / +3 had 128k, and joystick ports. The +3 had a disk drive.

I may still have imagined it.

Okay, I did not imagine it - https://spectrumforeveryone.com/features/inside-codemasters-...

But it's not really a CDROM.

Bold. In a different timeline they could have been the nvidia.

Absolutely: https://www.transputer.net/tn/46/tn46.html Too bad the UK gov were so shortsighted, or that Atari, instead of making the ATW ( https://en.wikipedia.org/wiki/Atari_Transputer_Workstation ) should have simply used a T212 in the ST blitter socket as a coprocessor. That way people could have slowly gotten familiar with the arch :| People are building new hardware to run transputers though: https://forums.atar…

Later model STs had an expansion connector on the PCB, it wouldn't have needed to be instead of the blitter.

CD-ROMs were pretty widespread in 1990-91 before RAM prices fell, I had a CD-ROM drive in a 386SX with 1MB RAM.

I realized just this month I miss the days of being able to crash my computer completely with a typo. Such a weird feeling. I was debugging some pcie passthrough issues this week and the feeling that the computer could go dark whenever I started the VM was fantastic. It took sooooo much time, and I loved it. Of course, I hated it at the same time. But I got the same feeling as when I was writing ring0 code at 14. Thi…

One of my favorite pastimes on my TRS-80 and TRS-80 color computer was to type in a simple basic program that would poke random values into random memory addresses and see how long it would take to crash or do something else.

Sometimes the value would wind up in the basic program itself and it would stop. Mostly it just locked up and I had to hit the power button and try again.

When something doesn't match your expectations you (and others reading along) can often learn a lot more if you start with the assumption you had missing information rather than the assumption it's just incorrect. Even in cases where the story really does have an error by asking about it instead of asserting it you are more likely to hear something additional you didn't know before.

The modern descendant of this stuff (intersecting group of people and ideas) is at https://www.xmos.com/

The target is the embedded space now, though.

This is so wonderful. I hope I can get your Transputer emulator running to try it. I wish I'd spent my teen years doing something so awesome. One minor grammar thing: "didn't worked" should be "didn't work", because "do" in English as an auxiliary verb always takes the root form of the verb, just as "will", "may", and "can" do. Similarly "don't exists" should be "doesn't exist".

Thanks for the suggestions! I've updated the article.

I'm delighted to have been of some service.
