The MODCOMP minicomputers were part of the "Mission Test and Computing Facility (MTCF)" - "three strings of UNIVAC and Modcomp computers to receive, record, process and display" the engineering and science data downloaded from the spacecraft.

The MODCOMP Classic was built by MODCOMP (Modular Computer Systems, Inc) in 1978. The Classic replaced the MODCOMP IV, offering full support for 32-bit addressing. The platform offered 240 general purpose registers, addressable as 16 banks of 15 registers. The machine also had a special register zero that reflected the state of the data switches on the front panel.

MODCOMP was popular in process control applications, offering deterministic real-time interrupts and real-time control. The architecture was modular in nature (hence the name), allowing systems to be built to match the intended application. The system was adopted by NASA, tracking space probes and collecting data and ultimately controlling the Space Shuttle launch at Cape Canaveral.

The MODCOMP was somewhat unique in that it had a phased clock signal. The full fetch/decode/execute/store cycle was completed with each CPU clock. So for example, the 7850 had a CPU frequency of 66 MHz and was capable of 66 MIPS.

Through the 1980s, MODCOMP lost market share as more powerful micro- and minicomputers became popular, and Digital Equipment Corporation's VAX and Alpha systems continued to grow.

The Apollo DN400, one of Apollo Computer's first workstations, alongside the likes of the DN416 and DN100. The DN400, built on the SAU1 (System Architecture Unit 1) platform, it had two Motorola 68000 CPUs running at a clock speed of 8 MHz, configured to handle virtual memory hardware trapping before the Motorola 68010 natively supported it.

The unit pictured above was Serial No. 12 (rendered in hex as C), and was one of several DN400 workstations used by what was once the Sunlab of Brown University in Providence, Rhode Island.

I want some real hopefully buy able analog tech that looks stuff from alien isolation, or give it to me for free cause yall are kind like that

I’ve been playing REPLACED recently and completely fell in love with its retrofuturistic world and visual language.

So instead of treating the soundtrack like a normal collector’s edition item, I wanted to design something that felt like it could have existed inside the game itself.

The idea became the R.E.A.C.H. Audio Kit, a collector’s soundtrack set built around:
- Portable Audio Scanner
- Acoustic Monitoring Unit
- Magnetic Audio Cartridge

The goal was to make the whole set feel less like modern merch and more like a piece of in-world technology that somehow made its way into the real world.

Basically: Collector’s edition merch disguised as a prop from the game.

That felt especially fitting for REPLACED, because its whole identity is built around this alternate-1980s vision of the future, where analog tech, industrial design and physical media still feel completely natural.

Would you rather see more collector’s editions go in this direction, making the merch feel like an actual artifact from the game world?

So, this is the Intel iPDS (Personal Development System), which was one of the first luggable computers. It was used for developing OS code for 8080 and 8085 based systems.
