A custom sized version designed to be suitable for any PC computer;
from standard ISA slot to PC-104 ISA formats.

As well, its reduced sized is intended to be compatible with very low profile PC computers
such Sinclair PC 200, Amstrad PC20 and other low profile based cases.

Board height is a bit less than 5 cm. , in order to be used in very low
profile PC cases.

The reduced size and weight is also oriented
to be suitable for most demanding courier systems, where
larger or more weighted packages could be problematic,


This custom version is focused in Sound Card emulation,
there are no space for MIDI output; with this unit you have:

• Gravis Ultrasound (GUS) - the primary focus of PicoGUS, hence the name
• AdLib (OPL2)
• Tandy 3-voice
• CMS/Game Blaster

Rapsberry Pi Pico is presented in a socketed way, in order to remove it
or replace it anytime you need,

Excellent concept! Makes me wonder if add-on boards of this low profile type was part of Amstrad's future plans for the Sinclair PC200/Amstrad PC20 if the machine sold well. After all, a non-standard expansion bay and non-standard cards means more people buying from Amstrad (at first). They would have to have made low cost add-ons for the line to be successful, though.

Some clarifications about this board and some use cases by already contacted users:
The design of this board is intended to be customized
for user and motherboard needs, the components can be
relocated at each side of the board, depending if the motherboard
or space restrictions demand it:





Regarding board design: Obviously some needs and some motherboards require a component placement that doesn´t look beatiful, such the example of my PC/104 motherboard; there are no space at the other side of the board, there are only 85 mm width space... a standard sized PC/104 board doesn´t fit (that is very usual in small form factors).



Such an user example, a French mate, he sent these photogaphs, published with him consent:






His PC/104 motherboard has no space for a standard sized PC/104 add-on board, the PCI connector at other end interferes, but this tiny sized sound card fit well, and cost around 5 times less than any hard to find PC/104 sound card board, that probably will not fit in his motherboard.


He needs the same solution as my case, but using a taller female PC/104 connector instead a male one.


Another use cases are two users that contacted:

=>One with a 386 SX that only supports up to 56 mm tall cards, and his ISA slot lacks the space between socket and bracket, and there is no brackets for addon card outputs/inputs ? Rare world, unique solutions


=>Other user presented a 486 motherboard, a big one that only presents PC/104 ISA expansion. The lenght between PC/104 ISA and a motherboard dissipator is 60 mm

A taller design will be better to avoid the 4 copper wires, impossible to route with 50 mm restriction, but this would left out these presented users,

This would be never happen,

These mates were awaiting around 30 years to be correctly attended,
now they are happy, their machines will produce high quality sound for the first time
