My first computer was a second hand, kit built Nascom1.
CPU was Z80 @ 2.34 MHz, 32 KB RAM, no discs. VDU was a 12" green screen CRT, capable of running from a 12V DC PSU. There was a huge 2KB video RAM on motherboard.
Main storage was a standard audio cassette unit operating at 100 bps.
Later upgrades added 8" floppies with CPM 2, a full 4 MHz Z80a @ 4 MHz and a full 64 KB RAM and a paged ROM board with 32 KB ROM chips.
This was followed by a Tatung TPC 2000, still in loft in working condition. Z80a @ 4 MHz and two 5.25" floppies of 710 KB each.
I eventually sprang to 16 bit stuff with a GCOM 386 @ 33 MHz and a massive 2 MB RAM, 5.25" and 3.5" floppies with 40 MB hard drive.
All this now seems like stone age relics but I did learn one hell of a lot about computers!
