Chapter 4 E20 Circuit description FileStore Service Manual 38
Chapter 4 4. E20 Circuit description E20 Circuit description Read this chapter in conjunction with the circuit diagrams for FileStore E20, in Appendix C at the back of this manual. The only part of the E20 unit which is serviceable by Acorn dealers is the Host Adaptor pcb (see circuit diagram) and its connectors, cables, etc. This provides an interface between the asynchronous SCSI interface the disc controller board, and the synchronous 2MHz expansion bus interface on the E01 unit.
Chapter 4 E20 Circuit description MESSAGE (MSG, pin 42) Is asserted by the target when it issues a message byte to notify completion of a command. See Bus phases, below. DATA BUS (DB0 to DB7, pins 2,4,6,8,10,12,14 and 16) Is a parallel data bus consisting of 8 signals from DB0 (least significant) to DB7 (most significant). 1 byte of information is transferred across the bus with each REQ/ACK handshake.
Chapter 4 E20 Circuit description The prescribed sequence is from bus free to selection to one or more of the information transfer phases to bus free again. There are no restrictions on the order of information transfer phases, and a phase will often follow itself, e.g. two data phases one after the other.
Chapter 4 (1) (2) (3) (4) E20 Circuit description Target asserts REQ to request data transfer Initiator asserts ACK when data is valid on bus Target deasserts REQ when darn has been transferred Initiator deasserts ACK ready for next handshake Prior to and during information transfer, the I/O signal determines the direction of the transfer.
Chapter 4 E20 Circuit description NPGFC (not-page &FC, pin 10) is a signal decoded from the top 8 system address lines (A8 to A15). NPGFC is an active-low signal which is low when the address high byte is &FC, i.e. when the full address is &FC00 to &FCFF. Four locations in this range are used by the Winchester system: &FC40 to &FC43 inclusive, see section 11.6.1. A0 to A7 (address low, pins 27 to 34) are the bottom 8 system address lines. D0 to D7 (system data bus) are the bi-directional data lines.
Chapter 4 E20 Circuit description The low order address lines A0 to A7 are buffered through IC5. IC6, a 3 to 8 line decoder with three enable inputs, decodes the low order addresses &40 to &43, i.e output pin 15 goes low when the low order address is &40, &41, &42 or &43. IC7 is another 3 to 8 line decoder which takes the output from IC6 and CNPGFC and 2MhzE as enable inputs. The 2 least significant address bits A0 and Al are decoded along with R/NW into the required 5 separate signals shown above.
Chapter 4 E20 Circuit description 4.6.3 Termination The Host Adaptor pcb carries 4 resistor packs, RP1 to RP4 which are used for terminating the various buses and control lines. RP1 terminates the SCSI lines from the hard disk controller board. IMPORTANT RP2, RP3, and RP4 terminate the 2MHz bus lines and are fitted if the E20 unit is the only or last peripheral on the 2MHz bus. If another peripheral is attached to the 2MHz bus through the E20 unit, then these terminators should be removed and retained.

Chapter 5 5. E20 Fault finding E20 Fault finding The following chapter describes the suggested methods of fault finding on a FileStore E20 unit when the fault is not clearly in a specific area. When the FileStore E20 is powered up, the following sequence of operations, should take place, as indicated by various activity indicators on the FileStore: (1) On initial power up, the power indicator and mode/activity indicator should light up. (2) The hard disc will spin up to speed in about 10 seconds.
Chapter 5 E20 Fault finding The hard disc unit: +5V +12V around 1 to l.5A up in 4.5A, falling to around 2A when up to speed. Host Adaptor board: +5V +12V around 500mA zero (not used) The above figures are approximate and will enable checks to be made for open/short circuits and malfunctioning components. 5.2 Address decoding To test the address decoding, execute a program to access the relevant memory location.

Chapter 5 4. E01S Fault finding E01S Circuit description Read this chapter in conjunction with the circuit diagrams for Stacking FileStore E01S in Appendix D at the back of this manual. 4.1 The Central Processor The processing power of the machine is provided by the 65C102 (IC16), an enhanced CMOS version of the 6500 series microprocessor with its own system clocks φ2 and φ4. This processor uses 8-bit architecture and runs at 2MHz.
Chapter 5 E01S Fault finding After the system is powered-up, whenever the device is accessed the ,CE is taken low when the address strobe (AS) is valid (high) /CE is initialised by the write-only latch at &FC08 IC14 pin 15. The address strobe is decoded as &FC00 from 12 and IC17. The memory address is latched in on the falling edge of the AS. When reading from the CMOS RAM within the 6818 (IC1) the RTC R/W line is held high and the data is read on the rising edge of DS.
Chapter 5 E01S Fault finding 4.4 Sequential Circuits There are four sequential circuits in FileStore: RAM refresh ROM/RAM latch Inton/Intoff Econet Clock These are described below. 4.4.1 RAM Refresh During every op-code fetch the processor activates (high) the Sync line IC16 pin 7. This has the effect of turning IC21 output pin 11 into the inverse of IC11 pin 8. IC11, the LS57, is wired as a divide by 60 frequency counter.
Chapter 5 E01S Fault finding During refresh control (i.e. when an op-code fetch occurs from RAM) the processor is reading hence pin 10 IC21 is always high. For further control of pin 10 IC21 see Memory read/write below. The RAS signal is generated from φ4. The purpose of the resistor capacitor network R17, C9 and R18, C8 is to alter the rise and fall times (i.e. stretch ) of φ4, hence producing RAS.
Chapter 5 E01S Fault finding read from the EPROM when the /OE and /CE are both low. 4.4.4 INTON/INTOFF Non-maskable interrupts (NMIs) are generated from two sources - the disc drive interface or the Econet network interface. Interrupts from the floppy disc controller function in the following manner: Upon start-up IC 19 pin 9 is cleared by the reset, causing pin 11 IC23 to be high, hence the NMI is high (inactive).
Chapter 5 E01S Fault finding 4.4.5 Econet Clock Generation IC15, IC27 and IC22 generate the Econet clock signal with selectable speed and mark space ratio. Links 6 and 7 select –l µs or 2 µs clock rates, derived from 0.5µs ф2. IC27 is a preloadable counter, links 5, 4 and 3 selecting loaded count 1, 2 and 4. The optimum setting is 200kHz. 1µs loaded count = 4. IC26 is the clock transmitter, enabled by CB2 on IC31. 4.
Chapter 5 E01S Fault finding In this application it is programmed to support 250kbps data transfer and MFM decoding. Cl1 and Cl2 are used to adjust the on-chip voltage controlled oscillator. The frequency produced (on TP2) should 250KHz +/- 12.5% when the FDC is in test mode (see the manufacturers data sheet). 4.8 The printer /VIA circuitry IC31 and IC32 control the printer interface.
Chapter 5 E01S Fault finding Y7(pin 7) low - enable IRQ When Y7 is selected, the least significant bit of the data bus (D0) is clocked into a D-type flip-flop (half of IC34). If this value is a one then the latch (2 NANDs of IC40) is enabled and an IRQ will be generated at the next falling edge of REQ. To disable Interrupts Y7 is selected with a 0 on D0.

Chapter 5 5. E40S/E60S Fault Finding E40S/E60S Fault finding The following chapter describes the suggested methods of fault finding on a FileStore E40S/E60S when the fault is not clearly in a specific area. When the FileStore E40S/E60S is powered up, the following sequence of operations, should take place, as indicated by various activity indicators on the FileStore: (1) (2) (3) (4) (5) On initial power up, the power indicator and mode/activity indicator should light up.
Chapter 5 E40S/E60S Fault Finding See Fig 9 for a diagram of the typical waveform produced: Figure 9: E40S/ E60S start-up waveform The above figures are approximate and will enable checks to be made for open/short Circuits and malfunctioning components. 5.2 Address decoding To test the address decoding, execute a program to access the relevant memory location. This is done by the SCSI interface tests in the FServTest program of the FileStore test software.
Chapter 5 E40S/E60S Fault Finding The correct voltages are as follows: 2 MHz expansion bus D0 to D7 and A0 to A7 should all be 2.5V. If for example, D0 to D7 are all at 0V or a mixture of 0V and 2.5V, then one of the buffers is probably enabled. 5.5 Final checks If the procedure outlined above fail to uncover the fault, then as a final check, you should refer to Appendix A - Test Equipment, which contains more thorough tests of the FileStore.
