Amstrad PC1512 were sold with monochrome or CGA colour monitor, while PC1640 could be sold with EGA colour monitor (PC MM, PC CM were the monochrome and colour monitors).
Keep in mind that some of these computers were upgraded later by their owners, so it's not strange to find a PC1512 with 3.5 floppy drives, or fitted with a MFM controller and hard disk (they have standard 8 bit ISA buses).
These computers were renamed in some markets, like the PC5120 and PC6400 (in USA). Also, the very rare Sinclair PC500 is a rebranded PC1512.
Some other computers to look for (8086 or equivalent CPUs)...
Amstrad PPC512/PPC640 8086 laptops made by Amstrad.
Sinclair PC200: A computer in a keyboard based on PPC512 hardware.
Schneider EuroPC: Another computer in a keyboard.
Commodore PC10 and PC20: A friend of mine had one of those. The PC20 adds a hard drive.
Olivetti prodest PC1: Yet another computer in a keyboard, not as compatible as other PC clones.
Amstrad 2086 / 3086 / 5086: Amstrad kept upgrading the cases, but not the CPUs inside the computers 😉 OK, that's not fair... these generations had models like 2386 (a 386).
Olivetti PCS86: Another modern incarnation of a 8086... really a Nec V30. This computer has a IDE-more-or-less compatible controller and VGA graphics.
Olivetti M24: I learned MS-DOS in one of those machines... really bulky.
IBM PS/1: A strange computer from IBM, it could boot from ROM (had MS-DOS 4.0 in ROM).
Canon Navigator: A strange mix of fax, phone and computer (compatible with MS-DOS 3.3). I've got one of those, and I'm willing to sell it.
There were many 8086 computer makers in the wild, so I suggest you to search the terms 8086, 8088, V20 and V30.
I have traveled across the universe and through the years to find Her.
Sometimes going all the way is just a start...
I'm selling some stuff!
