yeah, something like that. you could fit quite a few stepper counters/controllers into this smol boi, if you use the block RAM creatively and use '595 shift regs as output expanders https://www.digikey.com/product-detail/en/lattice-semiconductor-corporation/ICE5LP1K-SG48ITR/220-2155-6-ND/
quadrature decoders, too, but STM32 chips tend to have a handful of those already

maybe it needs to be marked as bootable
Armbian comes with a first-run script to resize the linux partition to the full media size automatically, maybe look there for hints

you could have waited just a few minutes to post the new thread for a much better chip of the thread

there are also a few BCD-to-decimal decoders in the 74xx TTL family, usually in the 7440-7448 range, some of which have outputs that can withstand higher voltages (automotive power is dirty). you'll still want to check the datasheets to make sure the devices can handle the voltages you'll be dealing with, or you'll need to regulate it down to whatever they require
the important part is the 74, which almost always tells you you're dealing with a commercial-temperature TTL-ish discrete logic device. the A and B revision markers may have been kind of important in regard to 40xx logic, but I don't remember offhand what they meant, possibly Vdd range or something like that
