The first computer I owned was a Sinclair ZX Spectrum which used an 8-bit Z80A CPU (1c1t). It had 48 kilobytes (yes, you read that right, not Megabytes or Gigabytes!) of DRAM RAM thanks the the ROM that contained the BASIC interpreter amongst other things occupying the first 16k of the Z80A's 64k of address space. It did not have a HDD, floppy disks were an expensive dream (loading and saving was via audio cassette) and I had to connect it to my 14 portable TV via a UHF modulator.

I have 16GB of DDR4 RAM, 500GB of PCIe M.2 ssd (with a further 6TB in “spinning rust" HDDs). Display is a Samsung 28 4k Displayport monitor Also have an Nvidia GTX1060 6GB graphics card in my current PC where the Z80A had to handle graphics and processing on it's own.
