NOTES

• Printed circuit boards are identified by the Assembly Number printed in the foil of the circuit board. The last two digits of the assembly number distinguish each board type, and correspond to the color coding of the board extraction handles.

• This schematic presents the 4KW RAM board-set so the assemblies are identified as 82,83,84. The connectors they plug into remain identified as N22,N23,N24, from the original design for 2KW RAM boards.

• IC locations are identified by a label of the form:U <assembly-type> – <enumeration>

orU <assembly-type> – <row-alpha> <column-number>

A few boards have the IC locations in the foil, these are used for the enumeration if present. For the CPU and tape drive boards the same enumeration as presented in the HP patent and service manual is used.For other boards, a row-column locator is used, with the row specified by a,b,c,.. and the column by 1,2,3,.. starting at the upper left corner.

• The symbol represents a connector pin. The solid black end is the male side, the white-filled end is the female side.Connector pins are identified by a label of the form:

N <assembly-type> . <pin>

• A small black rectangular marker on the upper half of a gate symbol indicates an open-collector output.

• Capacitance in microfarads unless otherwise noted.

• This schematic is based on a reverse engineering of the 9830 board assemblies listed in the accompanying table, along with some use of the 9830 patent (US #4,012,725) and the tape drive schematics available in the the 9830 service manual.

• 2013 Spring - 2014 Spring: Drawn by bhilpert.2014 Oct 02: typo correction nMW75-->nMW15, pg M8.2014 Oct 12: corrections to 9866 connector pin labels, pg F2.2014 Dec 26: correction, U42-c2.2 to V+5 rather than GND, pg D1.

Memory Bank Address Map

RCK

Basic Timing

Shown is a full 16-bit microcode cycle, as defined by RCK (ROM clock). The number of pulses of SCK (bit-shift clock) within an RCK cycle, and hence the high period of RCK, is variable from 1 to 16, as determined by the binary code presented by microcode bits CC0,1,2,3.

This is an idealised presentation of the timing relationships, the real-world edge relationships will differ somewhat.

Measured values:MCK high=60 ns, low=65nSRCK low=180nS, lagging MCK –edge by 40nS

RAM Refresh Timing

MCK

RUN REFRESH20.125µS

In each refresh cycle, 32 memory access cycles are performed, one for each row in the 1103s. The refresh memory access cycles each require 5 MCK cycles. An additional MCK cycle is needed to transition into the refresh period, thus:

refresh period = (1+ 32*5 ) * 125nS = 20.125µS.

The run period is determined by the refresh delay monostable, so varies with RC tolerances. The calculated design target for the monostable is 820µS. This will be rounded out to allow completion of an RCK cycle. Each refresh cycle only refreshes half the RAM memory banks however, with a given bank being refreshed on alternate cycles. The effective refresh rate is approximately:

refresh rate = 2 * (820 + 20) = 1680µS, or 595 Hz.
