Hi everyone, just saw the news! 😃 https://www.space.com/39251-on-this-day-in-space.html https://en.wikipedia.org/wiki/Orbiting_Solar_Observatory Fun fact: The early OSOs were featured in an old German documentary series called "Was sucht der Mensch im Weltraum" (What is mankind looking for in space) …

As for early Javascript, I discovered very few resources. They are few and far between. I don't know for sure, but maybe books can be helpful here. It maybe sounds strange, but in these days most resources about the internet could be found in libraries. Depending on where you live, a visit to a …

Nice, it's really charming! 🙂👍 It's funny how human feelings work.. Just a few years ago I would have felt that this design is basic. Looking backwards from 2021, it feels very tidy and professional. The human mindset is really strange. We don't know what we've got until it's gone.

Harris originally planned on offering chips up to 33mhz but had too low of yields Would have been quite interesting having a 286 that ran circles around many 386 machines +1 The 80286 was a "limited", but serious design. - Limited in so far, because the 80386 essentially was considered a real …

Not sure if this is helpful, but I prefer CF cards and DOMs. I tend to avoid SD cards and SATA HDDs, because they require active adapters in order to be usable on IDE/PATA. Which sadly are often of not so high quality. The ones that I had gotten in the past often had bad soldering, ran hot or were …

^Great analysis IMHO 😎 I second, it's likely a special purpose board. An RCA/Cinch/Phono plug could interface with about anything, not just composite. Might be a signal generator, a form of digital multimeter etc. It could be anything, I'm afraid. 😅 Maybe the data in the EPROM chip contains a …

Are you aware of any software tools or trickery so i can increase my conventional memory to be more than ~580, by using the expanded memory that's available ??? Thanks, Terrence Hi Terrence! I see, makes sense. You can try out "The Last Byte Memory Manager". It turns the EMS page frame into an UMB, …

Hi, yes. Some programs can use EMS, which makes them use less conventional memory. Some motherboard chipsets do feature EMS, but also can repurpose the EMS page frame (the EMS "window") as a 64KB UMB. UMBs are also available in a PC/XT system. However, it often requires installing a physical RAM …

To be fair, they were crap when they were relevant. If we're speaking of the 2000s onwards, then yes, I agree. Not in the 70s, 80s and 90s, though. In that time line, quality still mattered. Any manufacturer who tried to sell low quality floppies would have had been boycotted by users. Because, …

Hi everyone, I'm looking for a pinout for my Nixdorf M35 PC.: The serial port is DB25, but female, like a parallel port. Does anybody know the pinout or if a simple gender change works? I don't want to break the RS232, but I'd also like to use a serial mouse. Best regards, Jo22

Collect less, play more, do you must. Rather good advice. These days you have to maintain what hardware you have as it certainly won't improve over time. All the hoarders with piles of crap they have no time to restore ... won't work next time they look. I often collect parts, too. But not as a …

Re: Can 1.44MB 3.5" Floppy Drive read 360K, 720K, 400K, 800K disks?

An 1.44MB 3,5" HD floppy drive can read 360KB and 720KB formatted floppies for sure. Even some old USB floppy drives still support these formats (bulky models often). However, it may be unable to do so sometimes if the floppies were formatted in another 1,44MB floppy drive. 360KB/720KB disks that …

That's very interesting, IMHO! 😎 Your work reminds me a bit of the old DXF and HPGL graphic formats, by the way. (In the spiritual sense.)
