Richard Cornwell's emulator is implemented within the OpenSimH framework, and forms the basis of PiDP-10: https://github.com/rcornwell/sims/tree/master?tab=readme-ov-... From the G…

The reason some of us MTBers switched: a single outing with rim-brakes in wet/muddy/dusty conditions would grind a set of pads to nothing (adding $25+ per outing for replacements),…

MPW had an interesting About box animation too. I recorded this back in 2011 using vMac emulator. https://www.youtube.com/watch?v=aJn3qxK9Br0

I think it is worth mentioning that this was Robert Dewar's second or third Ada implementation (depending on how you want to count them). Robert was involved with the original Ada/…

"PCI-e is descendant from Infiniband which in turn is decendant from ServerNet ..." When you say PCIe descended from IB, at the signalling layer or a higher layer? Can you suggest …

I asked Wilm in Sep-2020 and three were produced as a one-off build, Wilm did not indicate any intention to produce more.

In computing history claims like "first" and "commercial success" need to be qualified and defined, and therein things become difficult since timing and thresholds matter to meet a…

This map from Feb-1978 shows Illiac IV connected to ARPANET (top-left of diagram): https://i.imgur.com/7hSaVVf.png By this time Illiac IV had been connected to ARPAnet since Nov-19…

I have been attempting to locate software for the Illiac IV. I corresponded with as many of the people involved with it I could easily find online and with NASA Ames (which has a h…

Unisys has helped but not unexpectedly the machines we are targeting were end-of-life in the late 1970s and so they did not keep software for them beyond that time.

We received some files from Release II.1 (early 1972) but it is missing significant components. After that time we have bits and pieces but nothing complete. We remain hopeful that…

As a reminder, we are still looking for complete distributions of the Burroughs B6700 MCP releases that include ESPOL/NEWP so we can complete an emulator and preserve this system i…

Exactly. We have to stop writing more C/C++ one day; can we at least autopilot down our freeways, and eventually colonise Mars on the back of a safe and secure language like Rust. …
