I find your reply fascinating, even if it doesn't make any sense to me.

I bought one of these off eBay for nostalgia's sake: Vectrex - Wikipedia[^] It's really cool and it uses a relative of the Motorola 6502. But the weirdest thing about it is that it has only 1K of RAM! Imagine being tasked to write a video game that doesn't use more than 1K of RAM! The sound effects are in league with the Apple ][. A single voice driving a single small speaker. Does anyone else like to collect vintage computing devices?

Of course it is, I'm not disagreeing. I just think everybody likes to remember the "good ol' days".

You mean like that '80-es ZX81 sitting next to a '90-es Sailor radiotelephone and a '60-es EICO oscilloscope? :laugh: Yes, I like old stuff.

At least I find it fun to read about. Yet I doubt that I would be spending many hours playin games on that machine :-) A small side remark: I looked around a few Wikipedia pages - some are of a strange kind, such as List of commercial failures in video games [^], which lists the Vectrex among 32 other gaming hardware failures, and also lists 27 gaming software failures. I mean: How did we survive in the old days, without Wikipedia to provide such absolutely essential information? :-) Another remark: Referring to 6809 as 'a relative of 6502' ... well ... Sure, they were both marketed as 8-bitters. Just like 8086 and MC68K were 'relatives', as they both were 16-bitters, at least externally. (68K had several 32-bit features, and 6809 had a number of 16-bit features.) But who cares about such details, 40 years later? (For those who remember the CPU wars of the 1980s, essentially between x86 and 68K: That is one of my prime examples to illustrate that sometimes, the best one does not win. But that is another discussion.)
I had the Radio Shack Color Computer (Coco), and it used a 6809 processor, was actually pretty impressive. Beyond the standard DOS OS that a lot of microcomputers of the time, RS also sold a version of OS-9, a small multi-threaded operating system (well, probably more of a task switcher, but still cool on such a small platform).

Ah, and it came with the very characteristic MC6847 graphics chip. Remember that awful text mode? You only have two choices of colors. Text can only be dark green on a light green background or brown on a bright orange background. Bleeding eyes are guaranteed and the fixed color palettes of the graphics modes are not better. The 6847 used to be quite common back then and even today is still relatively easy to find for building your own 8 bit computers. I have two of them in my parts box. but when the day ever comes that I will actually build a graphics card for the Zwölf, I will probably take a TMS9918 instead. Or, if I actually have to use it, I will probably 'forget' to correctly mix in the color signals and leave the video signal grayscale only.

I think that's more computing power than Honey the Codewitch uses on a daily basis. :laugh:
That could be true: Not long ago, I was working on an IoT-project (similar to Honey) using an ARM M0 that could be clocked as low as 32 KiHz. Total power consumption is very dependent of clock frequency, and IoT is very dependent on not draining the batteries too fast. This M0 at 32 KiHz had extremely low power requirements. (A common in-house joke was that it could run on the leakage current from the battery :-)) I would not be the least surprised if an 1.5 MHz 6509 could do a lot more that that ARM IoT chip. At the same time, I suspect that the factor in power requirement was a lot higher that the factor in processing power.

You mean bronze age of computers. Today is the golden age. You can go down to the store and pick up a perfectly useable one for less than $500 that will handle some pretty impressive games that would have been utterly impossible back then, even if you shoveled out over $10,000. Or a million dollars, for that matter. I remember doing FEA in college, and the computation took hours to days. Now it is pretty much instantaneous. God, I don't miss those old 386's. Bootups in minutes...

Lead. The correct metal to name the age after would have to be lead, as in soldering together your own hardware. These also still were the days when my old cat used to toast her rear parts on my 4k RAM expansion.

No. It's quantum mechanics that you may need these days to explain why your junk does not work. On top of the traditional ones like capacities, inductivities, noise in general, thermal problems or timing problems, of course. Even those in all possible combinations could be quite arcane to track down.

I find it fun to take trips down memory lane, but have neither the space nor the budget for anything other than modern equipment.

I have several ZX Spectrums 48K and two Sinclair QLs. I also collect vintage Slovenian (Yugoslav) computers. I write software for them. I know about Vectrex, because I was evaluating the possibility to emulate it on an old Slovenian CP/M machine called Iskra Delta Partner. This machine has a vintage graphical chip that can draw vectors fairly fast so I was hoping to utilize it. However, besides 1K of Vectrex RAM you also need to emulate the 8KB of ROM and the 32 KB of cartridge ROM. And that together is 41Kb. Add the emulator and memory for remembering emulated vectors and ... I'm still thinking about it. But I realistically only have 112KB of RAM available, if I ditch CP/M and take control of the whole banked system. Anyone here writing software for retro 8-bit machines?

Was that the chip used inside the TI-99/4A home computer?

Did the Iskra Delta Partner have a vector display?

Sort of. It does not have a vector display, but it is driven by (the Thomson EF9367) chip that can only do Bresenham lines and 5x8 chars and there's no access to the raster. So for graphics you are limited to line drawing (or the 5x8 font which is also drawn by lines and can't be clipped). The Iskra Delta Partner GDP (graphical model) is quite special because it also has the SCN2674 chip for text only mode and it "glues" the video outputs by both chips into one image and text area is larger then graphics area. Quite exotic. :)
