refarding that failures list, for me meeting high expectations is not same failure.
never released to market is likly the story of 100 to 1 products never released. Pippin, 64dd, sega cd, 32x.
oh we only sold 9 million, boo, we wanted a billion: Sega Saturn, Dreamcast, VirtualBoy, WiiU,
I saw enough in the world, but still marketcap expectations: ngage, ps vita.
yeah, the paragraph is enough to explain its dislike: ps classic.
for any others, if the companies broke even, well guess what, stop being greedy.

I put together a GitHub - Kris-Sekula/mgh80: Simple 5 IC Z80 singe-board computer[^] kit, just for the fun of it. I played with it for a while then I got another simple Z80 board, added a keypad, 6 - 7-segment display and created a monitor program for it in assembler. Had a lo9t of fun with it but haven't had a chance to go back and do any more with it.

Looks interesting! Must've been like programming a TRS-80!

Probably, never had one. Had a Commodore64, that was a lot of fun.

I think that's more computing power than Honey the Codewitch uses on a daily basis.

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

A full working ZX Spectrum 48k is in my desiderata. I miss it.

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?

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.

Um, the 6502 was a MOS Technology processor. Motorola did make a 6802 micro back in the day.

I kept my Commodore 64, my Commodore Pet 2001 with the chiclet keyboard, my Franklin Ace 2000 (Apple IIe clone), and an assortment of green screen and color Wyse terminals for many years. I think it was after my 2nd child was born, and we needed the space, that I finally sold them off. I wouldn't mind having my Pet back. I think that one was my favorite.

But they probably expected you to add more ram in the cartridge if you needed it.
