Self modification makes a lot of this a lot easier.
While a lot of these technologies are tricky without self modification, but if you can self modify you can do a lot of these better. Imagine a species that has an extremely strong self repair ability and regeneration. They are one with nature, as the phrase goes. They can then emulate a lot of technologies.
This would be likely to happen on a very metal poor planet, where their only native resources were biomass.
The steam engine can be emulated by grafting people onto animals
The main reason the steam engine is useful is because it allows you to move people very quickly a huge distance. But birds are even faster. They can graft their brains onto birds, much like the infamous Vladimir experiment where he grafted a head onto a dog, and move huge distances. New bodies can be grown on site with enough biomass. More advanced technology, victorian level, would let you freeze a newly grown body so you could just plop your head on it and walk around immediately.
Likewise, more advanced experiments would let you replace the brain of a large elephant like animal to move large objects.
Automated machines could be made with factory lines of sliced out brain parts.
A lot of the inventions are really useful because they allow you to train a machine to do a regular task. This could be replaced with a factory line.
Extensive experimentation in brain removal would discover that you could remove certain brain parts, and get a body that would do a regular task on command. People would repeatdly learn how to do a task, have that part of their brain sliced out, regenerate it, and repeat. This lets you make factories which can do whatever you want.
Computers can be replaced with sliced out brain parts.
Rather than turning sand into electronic minds, you could turn brains into automated machines. Extensive experimentation with slicing out brain parts would discover you could network them together to do particular tasks. People supplying computers could repeatedly learn the needed skills, have that part of the brain sliced out, and supply more.
Steel production can be replaced with biosteel.
It's extremely common in the animal kingdom to do biometals. Our bones and teeth are mineralized calcium, bacteria use mineralized iron and beavers use iron to strengthen their teeth. Biological materials are custom made with precise structures, and are often stronger than their native compounds. Spider silk say is stronger than steel.
They can find a native organism which processes bioiron, like the beaver, and extensively crossbreed and modify it to produce biosteel, so they can have widespread access.
Biomineralized silicon lets you make inorganic computers.
Some organisms use silicon to grow internal structures. This could be changed by extensive genetic engineering to grow computer chips.
Historical progress.
Prehistory
The race in question, which we shall call trolls, is extremely hardy. Harsh conditions on their homeworld have forced most organisms to get extremely strong regenerative abilities. They regenerate any lost body parts rapidly, and can quickly heal from horrific wounds. Early experiments in prehistory with captive enemy prisoners discovers that if you grow a part of a troll with a fetus of a native organism then you can then crosslink the two. Unknown to them, this depended on luck and genetic compatibility, but extensive experimentation soon domesticated a number of native organisms, allowing them to be controlled by the trolls.
Families which did this had a guaranteed income, and formed guilds around controlling particular animals.
Iron age
In the iron age a number of organisms were discovered that used iron from meteor hits to grow shells and teeth. While iron was still extremely rare, some prized weapons were grown from such organisms, and extensive breeding allowed the shape and size of such things to be customized.
Medieval age
The domestication of a fast herbivore and a fast large bird allowed the feudal era to expand. People could cut off body parts, grow new bodies from them, have them shipped afar, and then fly their heads to them to be re-attached. This allowed a lot of mobility and movement, and many large troll empires were formed with the increase connectivity, and many large wars happened.
Industrial era
Extensive experimentation with captured prisoners discovered that you could remove a part of the brain, and get a brain dead troll which would follow a certain set of rules. This, along with the discovery of several large meteor impacts in more primitive regions which had a lot more iron allowed the industrial era to begin. Large machines which relied on strung together troll brains allowed the mass production of useful goods and the expansion of the economies of advanced nations, along with more extensive use of iron and steel to make powerful war machines.
Modern era
With their biotechnology substantially ahead of our own, they quickly discovered the secrets of genetics, cells, and modification. Experimentation with the losers of wars yielded many secrets, and new techniques, like multiple eyes strung together, were used to pierce the secrets of tiny things.
With this came the discovery of microscopic organisms which had much wider arrays of biological mineral deposition. One useful one used silicon as a type of skeleton, and experimentation discovered this could make a crude brain. Over time, computers, often crosslinked with troll brains, would start to spread, and civilization would reach the same heights as our own.
