Changes in Z-386 CPU board Artwork

Introduction
The current and the original Z-386 CPU artwork differ
significantly in component location designations. Changes
to JUMPER and PROGRAMMABLE IC (PALs, ROM) location
designations can create considerable confusion. The purpose
of this report is to cross-reference these changes.

The former 6 layer CPU boards are identified by the number
85-3334-0x (part number of the unfinished printed circuit
board) silkscreened on the component side above the 80287
co-processor socket (U256). The finished board part numbers
were 181-7043-10 through 181-7043-2X

The new 4 layer CPU boards are identified by unfinished
printed circuit board number 85-3408-0x silkscreened on the
lower left edge of the component side. The finished board
part numbers start at 181-7043-30.

The following is a cross-reference between the jumper
locations on the old and the new artwork:

Switches

Switch designations, locations, and functions have not been
changed.

Other Changes
The values of R204 and R206 and R209 have been changed from
75 ohms to 47 ohms.

Published Reference Material
Current published reference materials including the
Technical Reference manual, the Owner's Manual, and the
Service Manuals use the old artwork designations. We have
been advised that these materials will be updated. We do
not know when updated materials will be available nor are we
aware of plans ensuring that users who have received
inappropriate manuals will receive updates.

Other Considerations
Intermittent failures can occur when the new CPU board is
used with the Z386 Cache Card. These failures occur when
HOLDA is asserted early in a refresh or a DMA cycle. The
problem usually disappear after the unit has warmed for
several minutes.

The cache card's Memory Control PAL (444-572-00) at location
U728, has been revised to 444-572-01 to correct this
problem. Cache card with part number 181-7320-1F and later
SHOULD have the new PAL installed.

CPU SWITCH SETTINGS (PN 181-7043)

SWITCH 201 SWITCH 202

SWITCH ADDRESS RANGE SWITCH ADDRESS RANGE
0 512-640k 0 800000-8FFFFF
1 100000-1FFFFF 1 900000-9FFFFF
2 200000-2FFFFF 2 A00000-AFFFFF
3 300000-3FFFFF 3 B00000-BFFFFF
4 400000-4FFFFF 4 C00000-CFFFFF
5 500000-5FFFFF 5 D00000-DFFFFF
6 600000-6FFFFF 6 E00000-EFFFFF
7 700000-7FFFFF 7 F00000-FFFFFF

If the switch is off, then zenith 32 bit memory is in that
range. If the switch is on, then there is no memory ,or third
party memory in that range.

For example, if there was a 1 megabyte Z505 memory board to
be configured as only system memory, no ems, then the
switches on the cpu board would be set to reflect that the
address range 512-640k was being used.Switch 0 of 201 would
be off, all others of switch 201 and all of switch 202 would
be on.

Similarily, if a 4 megabyte Z515 memory board was being used
with no ems, only system and extended memory,then switches
0,1,2,3 of sw201 would be set to "off" , and the remaining
switches 4,5,6,7 of 201 and all of 202 would be set
to "on".

If ems is enabled on a Z505,and it is the first memory
board, then either 256k or 384k is available as ems,
depending on the base memory size being set to 640k or
512k,respectively.

If a 1 megabyte Z505 memory board has ems enabled, and it
is not the first memory board, then the entire board is
ems.

If 4 megabyte Z515 memory board has ems enabled, 2 megabytes
of expanded memory is available. The base memory card retains
a specific amount of system memory, as determined by the
setting of switch 3 on the memory card. Therefore, the CPU
switch settings should "off" for switches 0,1; "on" for
switches 3,4,5,6,7 of sw 201, and "on" for all of switch 202.

The CPU switches are set to indicate the total amount of
EXTENDED memory.

Memory board addresses should be contiguous. The base memory
addresses are altered if ems is being used.

The first memory card will always have a base address of 0.
If a Z505 has ems enabled, the next base address will still
be 1MG. However, if a Z515 memory card has ems enabled, the
next base address will be 2MG.
Board/s with ems should have the higher base addresses.

If a Z505 is not the first memory card, and has ems enabled,
then the base address setting does not apply.However, to
avoid confusion, it is a good idea to set it to the
corresponding valid base address.

4 MG Z515 memory boards with ems disabled should be
configured on four megabyte boundaries (0,4,8,12).

4 MG Z515 memory boards with ems enabled should be
configured on two magabyte boundaries (0,2,4,6,8,10,12,14).

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
