This signal sets a latch which asserts the outputs on pins 7 (/ROMEN) and 6 (/ROMCS) of IC1 which enable the interface 1 ROM (102) and disable the Spectrum ROM, respectively. With interface 1 connected, the Spectrum software brings up all zeros on the address line inputs to IC3, forcing input pin 3 (DECODE) on IC1 high. In normal operation, the Spectrum program transfers to address 8 when it finds an instruction it does not recognise, and an error message is displayed on the screen. The function of C3 is to enable IC1 to substitute the interface 1 ROM (IC2) for the Spectrum ROM whenever an error code is generated by the Spectrum BASIC. The link shown on the circuit diagram between IC1 pin 5 and capacitor C3 is included so that the circuit can accommodate, sometime in the future, a self-oscillating replacement for IC1. It provides a very high drive level to IC1 with a very high slew rate. IC4 is a fast CMOS integrated circuit which forms, with crystal X1, a clock oscillator for the gate array IC1.

These and their major functions are set out below:Ī) IC4 - oscillator for IC1 b) IC3 - address decoder to page ROM IC2 c) IC2 - ZX interface 1 ROM d) IC1 gate array controller of microdrive, RS232 serial link and network. The circuit comprises 4 integrated circuits. A block diagram of the unit is given in Figure 1.1. Microdrive, RS232 link and network functions. ZX interface 1 also provides an extension to the Basic Spectrum software which incorporates all the To form a network, and can communicate with other computers and peripheral devices via the RS232 Using it, the Spectrum can control up to 8 microdrives can connect up to 64 other Spectrums 39ġ.1 ZX INTERFACE 1 The ZX Interface 1 combines the three functions of Microdrive controller, local area network and RS232 37ĥ.1.5 ZX Microdrive Head Chassis Assembly. 37ĥ.1.4 ZX Microdrive Base Board Assembly. 36ĥ.1.3 ZX Microdrive Head Board Assembly.

These include sections on the way the memory is organised, how the computer manipulates numbers, and a series of example programs illustrating the power of the ZX Spectrum.Sinclair ZX Interface 1, Interface 2 and Microdrive Service Manual Spectrum For Everyone ġ System Description. The more of your own programs you write, the better you will understand the compute At the end of this programming manual are some appendices.
Whenever the manual tells you to type something in, always ask yourself, "what could I type instead?", and try out your replies.

of this Introduction shows you how to use the Calculator. The calculation and results are displayed on the screen. Calculator This option turns the keyboard or keypad into a simple calculator.

If you have the question "what does it do if I tell it such and such?" then the answer is easy: type it in and see. Spectrum BASIC is described in the ZX Spectrum+ User Guide, and pages 6 - 8 of this Introduction give full details of the extra features. Whatever else you do, keep using the computer. Look through them, and do any that interest you, or that seem to cover ground that you don't understand properly. Don't ignore these many of them illustrate points that are hinted at in the text. You will also find some exercises at the end of each chapter. This BASIC manual starts by repeating some things given in the introductory booklet, but in much more detail, telling you exactly what you can and cannot do. ZX Spectrum BASIC programming Sinclair BASIC programming booklet included with a new ZX Spectrum Condition: Good. You should also be aware of the commands: PRINT, LET, and INPUT (which can be used on all machines that use BASIC), and BORDER, PAPER and BEEP (which are used on the Spectrum). Chapter 2 Basic programming concepts Programs, line numbers, editing programs using, and EDIT, RUN, LIST, GO TO, CONTINUE, INPUT, NEW, REM, PRINT, STOP in INPUT data, BREAK This manual is mainly dedicated to the ZX Spectrum core, there is a section dedicated to other cores. Whether you read the Introductory book first, or came straight here, you should be aware that commands are obeyed straight away, and instructions begin with a line number and are stored away for later. A guide to the ZX Spectrum keyboard and a description of the display.
