Est. 2011 · Cyberdecks & service
We built our first deck after seven years of repairing other people’s.
That is the whole company, and it is why our spec sheets are dull. A deck you cannot open on a bench is a deck somebody throws away, and we have never been willing to make one.

Plate 2 · The range
Five marks. Three of them you can still buy.
We do not retire a deck because it is old. The Mk III is seven years into production and outsells the Mk IV with anyone who works outdoors, because it is sealed to a standard the Mk IV is not.
The one that taught us to design for the bench.

Specifications for all five marks side by side, memory boards and accessories with part numbers, and what is actually on the shelf this week.
Plate 3 · The constraint
Memory is the scarce thing. It has been since the first deck anybody built.
Every honest specification sheet in this industry says the same thing in different words: you will run out of memory before you run out of anything else. Link rate is cheap. Latency is a matter of layout. Memory is graded, matched silicon and there is never enough of it.
So we print two numbers rather than one — what is fitted, and what the bus will take — and we tell you when the second number is a bad idea. The Mk III will physically accept a 24 MB board. We will still suggest a Mk IV, because the scheduler on a Mk III was designed around four resident programs and paying us for a board does not change that.

And a 32 MB deck is not 32 MB of warez
Firmware, the ICE reserve and scratch take twelve megabytes of a Mk IV before you load a single program. Twenty are left for warez. We would rather you read that here than discover it in the field with a Sentry waking up.

Plate 4 · Service
The service department is not a department. It is where the company started.
Fenn Street has been taking in other people’s decks since 2011 and it still does, including our competitors’. Three service levels, published turnaround, and a figure on the docket before anything is fitted.
| Level | Code | Acknowledge | Turnaround | Loan deck | Charge |
|---|---|---|---|---|---|
| BenchThe default. Post it or bring it in. | CS-SV-B | 1 working day | 10 working days | No | Diagnosis 40 cr, credited against the repair |
| PriorityFor a deck someone is waiting on. | CS-SV-P | 4 working hours | 3 working days | On request, same mark | 180 cr per docket, plus parts |
| Field exchangeFleets of six or more. Ask for terms. | CS-SV-X | 2 working hours | Next working day, replacement deck | Included — you keep the replacement | Contract, from 1,400 cr per deck per year |
Measured, not promised
Bench SLA is ten working days. Median last twelve months: 6.2 days, 94.1 % inside. The months we miss get published too.
Parts, for a decade
We hold service parts for ten years after a mark is withdrawn. The Mk I came off the line in 2021 and is serviced until 2031.
Other makes too
Including Nitrosoft, out of warranty. We will tell you before we open it whether we think it is worth the labour.

Why our specification sheets are boring
Because a specification sheet is a promise, and the interesting ones are usually promises about conditions nobody will ever reproduce. We publish figures measured at the works, on production hardware, with the numbers that got worse printed in the same size as the numbers that got better.
The Mk V is heavier than the Mk IV and runs half an hour shorter on a cell. Both of those are on its page, in the table, above the good news. Our competitors at Nitrosoft publish benchmarks; they are not lying, and their decks really are quick. We would just rather sell you something you can still get repaired in 2039.
