CENTRONICS
PORT - (DMV 1986)
The Schneiderware
Centronics Port is an external 8bit Printer Port, published by german magazine
CPC Schneider International as part of their Schneiderware DIY series.
The plain PCB, or the fully assembled board were also available via mail-order.
The ECB Bus connector
of the board is intended to be plugged into the Schneiderware Basisplatine,
but it could be also wired directly to the CPCs Expansion Port.

V24
MODEM - (DMV 1986)
The Schneiderware
V/24 Interface is a RS232 Interface, published by german magazine CPC Schneider
International as part of their Schneiderware DIY series.
The plain PCB,
or the fully assembled board were also available via mail-order.
The ECB Bus connector
of the board is intended to be plugged into the Schneiderware Basisplatine,
but it could be also wired directly to the CPCs Expansion Port.
The V/24 board
additionally requires a Schneiderware Power Supply (or another external
power supply with +12V/-12V).

ALTERNATE VERSIONS
There seem to
have been one or two alternate versions:
The photo in
the original article showed a different PCB with Gl1 and Gl2 differently
arranged. And, the whole design is somehow mirrored or rotated (looks as
if the components are installed on the solder side).
That photo may
have been a prototype, or faked dummy for illustration purposes. Later
adverts are showing the "normal" Gl1/Gl2 arrangement.
The magazine
later released a correction on their Letters page which recommended to
replace the 5K6 and 10K resistors on the L200 voltage converter - it sounded
perfectly reasonable - except that,
The DIY project
doesn't contain any of that components. The correction (if it wasn't total
nonsense) implies that the magazine shipped different PCBs to some people
via their mail-order service.
And aside from
the "official" Schneiderware supply, one could of course use any other
suitable power supply. Nowadays, it would be easiest and cheapest to use
an outsorted PC power supply, which provides perfectly regulated +5V, +12V
and -12V with more than enough Amperes. |
|
POWER
SUPPLY - (DMV 1986)
The power supply
is needed only for Schneiderware projects that do require special voltages,
or for projects that do overload the CPC's own +5V supply (which may happen
when connection too many expansion boards, for example). The supply outputs
the following voltages:
+ 5V DC
- needed only when the CPC's built-in supply gets
overloaded
+12V DC - needed
for the Schneiderware V/24 Interface and
the Schneiderware Analog Converter
-12V DC - needed
for the Schneiderware V/24 Interface only
+24V DC - not
used (was intended for the EPROM Burner,
but when the EPROM burner was released, it
contained a 5V-to-25V converter, and thus didn't
need the +24V anymore)
Aside from the
components on the PCB, one does also need a transformator, which isn't
shown on the photos. Despite of being a very important component, the DIY
article contained only few side-notes on the transformator. The thing must
provide a number of AC voltages, and it might be difficult to find a matching
transformator (one could get one from the magazine via mail-order, but
it wasn't cheap).
Connection Cautions:
The supply uses
the same type of 2x32 pin connector as the other Schneiderware boards,
however, the supply is NOT intended to be plugged into the ECB Bus sockets,
instead, it should be wired to the 7 soldering points on the Schneiderware
Basisplatine.
Namely, it connects
to the three GND pins, and the 5V, and -/+12V pins. The seventh pin, "AC",
is left unused (it's been intended for rechargeable "ACCU" batteries, but
the later RTC and SRAM projects contained their own batteries, and didn't
use the "AC" supply).
The CPC's internal
+5V supply should be disconnected when connecting the external power-supply,
otherwise something terrible might happen (for example, when one supply
tries to output a few more volts than the other, or so).
The giant cooling
plate (and the LM323K voltage regulator) aren't meant to be mounted directly
on the PCB, but rather stacked a few centimenters above of the PCB (can
be seen on photos in some of the later adverts).

REAL
TIME CLOCK - (DMV 1986)
The Schneiderware
Real Time Clock is a battery-backed RTC, published by german magazine CPC
Schneider International as part of their Schneiderware DIY series. The
plain PCB, or the fully assembled board were also available via mail-order.
The ECB Bus connector
of the board is intended to be plugged into the Schneiderware Basisplatine,
but it could be also wired directly to the CPCs Expansion Port.
The Schneiderware
Real Time Clock is somewhat similar to the CPCI Real Time Clock released
in a special issue of the same magazine, but not identical (the RTC chip
has different pin-outs, and some of it's 4bit registers are working slightly
different, the leap-year bits, for example). The I/O ports are also slightly
different: The Schneiderware version has additional control bits in port
FBE2h, and, for whatever reason, it splits data to two separate addresses
(for FBE3h for writing, and FBE4h for reading), rather than mapping both
to FBE3h.

AD/DA
- (DMV 1987) - WANDLER / CONVERTOR
The Schneiderware
Analog Converter is a A/D and D/A Converter with 8 analog inputs, 2 analog
outputs, published by german magazine CPC Schneider International as part
of their Schneiderware DIY series.
The plain PCB,
or the fully assembled board were also available via mail-order.
The ECB Bus connector
of the board is intended to be plugged into the Schneiderware Basisplatine,
but it could be also wired directly to the CPCs Expansion Port.
The D/A converter
additionally requires a Schneiderware Power Supply (or another external
power supply with +12V) (eventually one could also use the CPC's disc drive
power supply; though not tested if the supplies in the CTM644/GT65 monitors
provide enough amps).

EPROMBURNER
- (DMV 1987)
The Schneiderware
Eprommer is a EPROM Burner, it supports 24pin and 28pin chips (max 32K
bytes), published by german magazine CPC Schneider International as part
of their Schneiderware DIY series. The plain PCB, or the fully assembled
board were also available via mail-order.
The ECB Bus connector
of the board is intended to be plugged into the Schneiderware Basisplatine,
but it could be also wired directly to the CPCs Expansion Port. The required
EPROM programming voltages are generated by a 5V to 25V converter (and,
where needed, lowered to 21V or 12.5V), so one doesn't need an external
power supply. The programmed EPROMs can be used (among others) with the
Schneiderware
ROM/EPROM board
