@ NODE problem "Our initial problem"
@ (B) The original problem UB @ ()
A friend gave me a Masoboshi Smart Card. This is a
pretty good 16-bit memory expansion card for the Amiga 2000. However,
unbestückt part, say there were no RAMs it. The real problem:
The card is required ZIP, which at that time outrageously expensive in comparison
to SIMMs. I had the time to have two 1MB SIMMs in the drawer,
So it was suggested that somehow into the card installed, which will ultimately
then succeeded.
@ ENDNODE
@ NODE consideration "reflection"
@ (B) The idea UB @ ()
A review of the SIMMs and ZIP showed that in principle the same
Signals are used, only the pin and the organisation is something
different. The pin SIMMs which I took from the offline hardware Book of
@ ( "Joakim Ögren" LINK) Thanks to the ZIP mainly from the schematic Commodore
A2630. However, there are a 256Kx4 types (here 1Mx4) and
another is the label some pins absolutely illegible. I had also
improvise a bit and hope that the occupancy of the "larger" just a ZIP
Enlargement, and that was obviously the case. In order to have control
I am also in the suppression of the Smart Card. What happened
The confusion could address some lines, but in general
no problems. There are only other memory cells
raised, but no matter what should be, because this is the same.
@ ENDNODE
@ NODE reconstruction "Rebuilding"
@ (B) (@ The conversion UB)
This modification should only be made by persons with sufficient
Experience in dealing with electronic components. These are
including the ESD (ETUC)-protection regulations (and the RAMS
other chips on the map and elsewhere in the computer are very sensitive to
electrostatic discharge). Nor should use an appropriate tool
find either a temperature (about 330 ° C) or
Not for a simple with a capacity of no more than 20W.
I have strictly no alteration made, but an extension. On
the map are now available to Bank 1 SIMMs or ZIP bestückbar. The whole
is that the solder joints for the versions with the ZIP
Wire-wrap wire SIMM two additional versions have been.
@ ( "Required materials" LINK material)
First of all stripes board cut so large that the SIMM versions well
to adapt and even a small edge to the mounting. Then in
Using a strip board is not required connections auftrennen
(e.g. with a drill or a wallpaper knife). Most versions SIMM
need holes in the PCB, in the Dorne made of plastic or metal
intervene now versions in accordance with the drill. The SIMM versions in
the matrix board and the board einlöten to attach the Smart Card.
This orientation to ensure the wiring is otherwise quite later
unfortunate. For mounting e.g. Hot glue or two components.
For me, the matrix board but only by the mass and
+5 V connections kept, which I slightly more Blank wire running
. This is not superstabil ranges within a computer but
usually by far. Now, the two boards under the
@ (Table) LINK wired connections. I voted for wire-wrap wire used because of this
the ends do not have to be stripped, but because of the slightly
wegschmelzenden isolation can be simply tin. But even a normal
Schaltdraht thin (up to 0.5 mm in diameter), thin or even Schaltlitze
Enamelled copper wire are suitable. The lines should be short
be executed, to avoid unnecessary and inductors to Schaltkapazitäten
avoid. In addition to long lines act as antennae, which in a
Computers in large quantities existing electromagnetic interference field.
Finally, the two 0.1 uF capacitors as close as possible to the
SIMM versions between mass and +5 V angelötet. In order to have optical control
I have two scans of the @ ( "component side" link "SmartCard_Best.JPG / main") and @ ( "solder" link "SmartCard_Loet.JPG / main") my prototype
settled, although this was quickly zusammengeschustert and not just
very good. Übrigend: The Elko down in the middle served only as a restraint
during scanning. ;-)
This would be the conversion of the card is finished, the outcome should be but everything
again wiring error, tin and other Murks conclusions,
because a mistake so the card, or even the Amiga the cost lives.

actually still work to continue should the access time of both

-- 2 versions SIMM 30-pin or a double version (I personally have the
SIMM versions by desoldering from a defective 486-Board "won", which
much cheaper than buying was:))
-- A small piece matrix board with pads or strip (even so
large that the SIMM versions to fit the need is even without, then
must be the SIMM versions are sent directly to the smart card sticking)
-- 2 0.1 uF capacitors (best ceramics, but also different types of slides are likely to
the value must also not exactly right, e.g. 0.22 uF can of course also
used, the cost can even omit them for the
Operational safety but recommended)
-- A little thin Schaltdraht or Schaltlitze best Wire-wrap wire, Not
also enamelled copper wire
-- A little glue (such as hot-or two-component glue) or some bridges
a little thicker Blank wire to attach the matrix board
The material should be consistently in an electronics shop, but
of course, by Ausschlachten for any old equipment can be gained.

The following table provides the necessary links between the
Smart Card (the ZIP versions and their joints) and the SIMM versions
. The individual columns have the following meanings:
Column 1 (SIMM Fkt.): function of the pins at the SIMM
Column 2 (no SIMM / Pin): Number of SIMMs (0 or 1) and number of pins at the SIMM
(see fig 3)
Column 3 (ZIP Code / Pin): Number of ZIP (0 to 15, see Figure 1) and
Number of the pins at the ZIP or the ZIP version (see

Column 4 (ZIP Fkt.): function of the pins at the ZIP
Extras:

This combination does not. You can select their conversion, the
Smart Card itself, the SIMMs or even blame the Amiga. It is well known
that some memory extensions in certain revisions not Amigas
work. The worst in this respect with Rev.4.x Amigas, but
also in other, the resources (such as myself besitzte with a 6.2,
the memory expansion of a nexus will not work, part of the SCSI
works against). Whether the card in a A3000 or A4000 works is
I do not know, but the slow 16-bit RAM makes little there anyway
Sense. If the smart card with ZIP (for a test if available),
then the fault is probably the rebuilding or the SIMMs.

The connection of SIMMs in the other three memory banks of the Smart Card should

correct address and strobe pipes. It could, however,
happen that the then quite long lines problems.
Not converted to normal with banks ZIP bestückbar, ie on a
Smart Card can now ZIP SIMMs mixed and served (even if
within a bank if ensuring that the ZIP Bit0-7 and the
Bit8 SIMM-15 or vice versa, but that is just my mind,
I have not verified whether this is in the existing wiring work).
Those who do not participate in the Smart Card will herumlöten can obtain ZIP versions,
the wiring to anlöten versions and thus plug for the

Contact problems at this point are excluded.
A similar transformation should also apply to other devices possible, the
ZIP normally. It also needs other forms of housing should
possible. The most dynamic RAMs have identical signals but
different organisation (for example, a 1Mbit chip in 1Mx1 or 256Kx4
organised) and Pin Assignments. How could it e.g. quite possible
DIL or SIMM RAMs in a A3000 to use the ZIP's actually needed.
Depending on the shape and size of the chips but the effort can be enormous
and we must take into account that not as many chips without additional
