Figure 17 Pin 1 NOTE plugging in a TRAM the wrong way round will may not result in the destruction of the module or motherboard The IMS B012 has some components mounted on the top as opposed to underside of the board in the positions occupied by some slots 101 3 23 under slots 6 7 and 14 When plugging a TRAM into these positions it will probably be necessary to fit stand off connectors to the TRAM pins These are 8 way pin strips which plug into the IMS B012 and into which the plugs and raise the module above the motherboard thus clearing the tops of the components on the motherboard These stand off strips are supplied fitted to INMOS TRAMs It is possible to remove IC1 3 and gain extra space under slots 6 7 and 14 Some types of TRAM may then be mounted in any or all of the slots on the board without exceeding the inter motherboard height restriction Of course the ability to use any link connections which are made via the IMS C004s or IMS T212 is lost If these ICs are to be removed please proceed carefully and use the correct PGA removal tool When the IMS B012 with TRAMs fitted is likely to be subjected to vibra tion or thermal cycling then the TRAMs should be securely fastened to the IMS B012 There are holes drilled adjacent to each slot Nylon bolts may be fitted through these holes to bolt down the TRAMs securely If TRAM with Subsystem capability is to be installed in slot 0 the only sl

50. y The IMS B012 can be connected to another board with subsystem control and can also accommodate one TRAM with subsystem control Furthermore the IMS B012 can generate subsystem control signals for other boards System services for TRAMs are slightly different to system services for boards since the Reset and Analyse signals are active low for boards and active high for TRAMs The 5 and other circuitry the IMS B012 splits into two sections for system services System services for slot 0 come from the Up pins on edge connector P2 System services for slots 1 to 15 and IC1 the IMS T212 can either come from from Up as slot 0 or from the Subsystem pins of slot 0 depending upon the state of switch 6 IMS T212 Error pin is unconnected so an error condition on IC1 cannot propagate into the TRAM array Note that slot 0 is the only slot which has subsystem pins and that in order to use these pins it is necessary to have a module with subsystem capability installed in slot 0 See section 4 3 system service signals for slot 0 are buffered and output edge connec tor P2 as the Down pins This allows system services for multiple boards to be daisy chained the Down of one board being connected to the Up of the next Figure 9 shows the complete organisation of the system services reset anal yse and error on the board Reset and Analyse signals presented to the IMS 012 on connector P2 should have m
