I made a thing! For those 3-4 people in the Fediverse who tinker with #Nascom and #GeminiMicrocomputers, I present: The 80-Bus Stop - convernient and safe storage for your 8x8" expansion cards. Enjoy ;-)

@etchedpixels @bonkers I think I read somewhere that some of the #Nascom guys started Gemini Microcomputers?
-
@etchedpixels @bonkers I know about xbeaver and am in contact with the author. I've always has a fascination with profession hardware like this, you know, wrapped in a minimum of +1mm metal plating 😂 I never laid my hands on a #Nascom system, but as I understand it, they were sort of the precursor to the Gemini.

Any other #Nascom or #Gemini #vintagecomputing geeks out there? I inherited a rather large collection from my late dad, but so far I've only found a handful of people why are into the #Galaxy computers made by Gemini Microcomputers Ltd., and none in the Fediverse yet. The Geminis were made in #England and mostly featured the #Zilog #z80 although they very briefly ventured into Motorola 68K world before throwing in the towel.

Found my first computer this week.
Nascom 1 (1978 ish) built into a wind up gramaphone case, swappable roms (tiny basic and a monitor IIRC) space for a Phillips EL3302 cassette player (that i also have some where) also found my software on tape.
Really need to archive those :)
Z80 at 4Mhz , 2KB onboard 1KB video, 1K user. 4K expansion (8x 2114's)

So my dad and I went on a last #roadtrip together. We rarely spoke, and almost never about personal things. He had two other families after mine, and gave most of his attention to the people right in front of him. That unfortunately meant that both of his grandchildren missed out on their grandfather and vice versa, which is probably the thing I'm most sad about. Fortunately we managed to catch up a bit during the last three months before he died.
When we spoke, we spoke about electronics and computers. The car is full of ancient vintage computers I saved from his estate. For the curious, it's Z80 based, #Nascom compatible computers from #GeminiMicrocomputers. More about that later.
So here he is, and so are some of his things. Peculiar how I'm flooded with emotion, when I hold some of the tools that I remember from growing up in his computer workshop. It was one of the few things we shared and he taught me - #computers and #electronics.

Once upon a time, I had a Nascom 1. But this is my Nascom 2, before I added an amber monitor. It must have been late 1980s...

@saustrup Og ovenikøbet i Århus! Jeg bliver helt nostalgisk.
I remember. I was there for all of this and even stuff before it. And I had a #Nascom 2.
It was definitely not a straight path and I question strongly whether we are at the best place we could have been, but certainly: we have been fortunate to be witness a unique period in human history with exponential technology growth sustained for decades. I think this is mostly over, eg. https://www.semianalysis.com/p/the-memory-wall

It's 1984 and my dad just finished his advertisement for the big Christmas computer fair. He had invested heavily in the Gemini series from #Gemini Microcomputers Ltd in England. I believe it was a #NASCOM compatible system, but the company unfortunately went bankrupt a couple of years later.
The 80s were full of opportunities and disappointments in the field of micro or even home computers. So many interesting ideas, so much competition and so few made it through. Everyone remembers the Commodore 64. Few remember the #Lynx, the #Enterprise, the #NewBrain or the #Gemini. Remember #CPM? No? #DOS won that race. Competition lead to better solutions which eventually gave us the computers we have today. Shoulders of giants and all that.

A single board computer with an 8035 CPU. I made it in 1979. As a slave to a NASCOM 1 {https://en.wikipedia.org/wiki/Nascom_(computer_kit) with a Z80 CPU} it was a little development system for 8048 microcontrollers. I implemented the ports externally, which the 8048 had, but which the 8035 occupied for access to an external memory. (As for the port timing, the performance of the system of course was not as good as with a real 8048.) No functional programming then. I used hex code.😓

Interesting! I didn't know #TurboPascal was originally a 12k ROM for the #NASCOM #z80 computer.

For 20+ years I have been chasing the version 1.3 of BLS #Pascal (have version 1.2); a few years ago I discovered a tape in a museum http://datamuseum.dk/wiki/Genstand:11000761 and today I finally got a binary version. The good news is that the version appears error-free. However, the starting address is unknown (no body has the documentation), so now I've hacking up a #Nascom specific #Z80 disassembler in Rust, trying to make sense if it. Not there yet.
