TL;DR
A curated TOPS-10 distribution assembled by Jimmy Maher provides a near one-click PDP-10 environment for hobbyists and researchers. The package includes the TOPS-10 OS plus FORTRAN and BASIC compilers and both versions of Adventure in source and executable form; users still need to supply the SIMH emulator.
What happened
Jimmy Maher published a packaged TOPS-10 installation on his Digital Antiquarian blog aimed at making historical PDP-10 software easier to run on modern PCs. The archive bundles a functioning TOPS-10 system configured to resemble a typical setup from about 1976–1983 and ships with FORTRAN and BASIC compilers. Of particular note to interactive-fiction enthusiasts, the package contains Will Crowther’s original Adventure and Don Woods’s expanded 1977 version in both source and executable formats, allowing users to run the games as they originally operated. Maher notes that recreation of PDP-10 environments is now feasible thanks to projects such as SIMH and archival resources like bitsavers.org, but that assembling everything can be difficult for those unfamiliar with historical system administration. The distribution includes a readme; users must obtain the SIMH emulator separately. The compressed download is about 60 MB and expands to roughly 300 MB on disk.
Why it matters
- Preserves and makes accessible historically important software and computing environments for researchers and hobbyists.
- Lets users experience interactive-fiction classics in their original system context rather than modern ports or interpreters.
- Lowers the technical barrier to running PDP-10 software by providing a preconfigured starter system.
- Demonstrates how modern emulation and archival projects can enable practical software archaeology on ordinary hardware.
Key facts
- The distribution was posted by Jimmy Maher on the Digital Antiquarian blog (May 20, 2011).
- It provides a working TOPS-10 operating-system installation representative of circa 1976–1983.
- Included toolchain components: FORTRAN and BASIC compilers.
- Includes Crowther’s original Adventure and Woods’s completed 1977 Adventure in both source and executable form.
- Users must acquire the SIMH emulator separately to run the package.
- The downloadable archive is about 60 MB compressed and expands to about 300 MB on disk.
- A readme file is included with the download to guide setup and usage.
- Author suggests the package is aimed at dedicated hobbyists or 'hardcore time travelers' due to size and complexity.
What to watch next
- Whether the author will assemble a similar prebuilt package for TOPS-20 and DECsystem-20 — not confirmed in the source.
- Community contributions that add more games or utilities on top of the starter TOPS-10 image — not confirmed in the source.
- Availability of networking stacks or TCP/IP for TOPS-10 in prebuilt images — not confirmed in the source.

Reader FAQ
What does the package include?
A configured TOPS-10 system, FORTRAN and BASIC compilers, and both Crowther’s and Woods’s Adventure in source and executable forms.
Do I need any other software to run it?
Yes — you must obtain the SIMH emulator separately; the distribution itself does not include SIMH.
How large is the download and how much disk space is required?
The compressed download is about 60 MB and expands to roughly 300 MB on disk.
Will a TOPS-20 or Zork-ready package be released next?
Not confirmed in the source.
