Now you can program the ZX Spectrum

OK, if you just want to be nostalgic and do some BASIC programming on the ZX Spectrum, click on the image below which will run a faithful emulation of the Sinclair ZX Spectrum complete with BASIC. For more information on Sinclair BASIC you can read the manual.

but here is a very simple program to get you started, follow the instructions:

1. type "10 LET a=10" - (note that the spectrum had short-cuts on the keys so immediately you press L it will display "LET" - you might find this weird at first but after you get used to it it's a very fast way to write a program). Then press RETURN (ENTER) - the code will appear at the top of the screen, that is the first line of the program

2. type "20 PRINT a" - (again, pressing 'P' will result in PRINT being displayed). Then press RETURN (ENTER). Your second program line will be displayed at the top of the screen.

to run the program type: 'R' and 'RUN' will be displayed. Press RETURN (ENTER) and the program will run and print "10" - voila!

Here's another program from the manual that demonstrates taking input from the user and the used of FOR loops:

10 LET total=0
20 FOR c=1 TO5
30 INPUT a
40 REM c=number of times that a has been input so far
50 LET total=total+a
60 NEXT c
80 PRINT total




and here is a screenshot of a program with a background of the original Spectrum keyboard:
