,/* The Plus series */
The Plus series were quite (but not 100%) compatible with the original CPC computers. The compatibility issues came mostly from:
* The emulated [[8255|PPI]] chip, making the keyboard unresponsive
* The emulated [[CRTC]], breaking CPC demos
* Unlike the original model, the 464 Plus lacks a tape counter for tracking cassette positions. It also omits the distinctive loading sounds that were once audible through the speaker during tape operations on the original CPC 464* Unlike the original model, the 464 Plus features the BASIC 1.1 ROM* The new AMSDOS ROM, breaking ROM access to the floppy drive ROM issues can be easily fixed by using a [[Plus System Cartridge|Downgrade System cartridge]].
The Plus series incorporated a list of [[ASIC|new features]], like a cartridge port for instant program loading, DMA for the [[AY]] soundchip, enhanced hardware scrolling, programmable interrupts, 16 hardware zoomable sprites (not vectorized) with an independent palette of 15 colours, and a choice of 4096 colours all in a new, sleek case which mimicked the keyboard-computer design that was ''en vogue'' in the 16-bit market (ST, Amiga etc).
