Further Notes on Open Genera on Linux

The previous notes don't seem to work in all circumstances.

In particular, trying to enable a CHAOS networking port in .VLM configuration causes NFS to fail in the writing of the Site file. I have been unable to diagnose this as it appears the VLM stops trying to use NFS to access the file after starting a write, and then times out, not even showing any activity on tcpdump when a restart is attempted. It's possible the presence of a CHAOS interface causes it to expect NFILE or perhaps it decides to prefer FTP over TCP. In principle, it should be possible to invoke the debugger on the VLM to understand what is going on, but all the networking is very flexible and elaborate and I have no idea how to debug Genera at this point. On the Linux side, I can find nothing at all that shows an error or misconfiguration or anything at all once the problem starts.

After defining the site and saving an incremental world, adding a CHAOS interface seems OK, but I have been stumped trying to get it to talk to a MacIvory over CHAOS or even TCP; probably this is because I don't understand how to bridge the VLM traffic onto my LAN and to the MacIvory and the reverse.

On another machine, even after disabling the CHAOS interface and successfully defining the site, Show Directory on HOST seems to not prefer NFS.

Before defining the site, accessing HOST: throws an error that refers to MAC-FS; perhaps the distribution world image is somehow configured for MacIvory behavior?

Open Genera VLM on Linux

There are some existing guides to setting up the (unauthorized) Open Genera VLM on x86-64 Linux, but I wanted to tweak them a bit, and came up with a couple of items that diverge from the existing advice. Note that a bunch of URLs on that link should point to https://archives.loomcom.com/  not the static.loomcom.com address. My general goals were to avoid having to run the genera binary as root, and run as a distinct user to have some sense of security (even if the sense is misplaced). I also wanted to change the network addresses, and don't want to use the standard pathnames for the Unix system files and the user directories, and the changes to do so were only in screenshots. My setup Ubuntu 18.04.4 LTS, amd64 My Linux machine is named ubuntu I want all this simulated Genera stuff to happen on  subnet 10.0.10.x  with my Linux host under the name  genera-ubuntu  at 10.0.10.1  and the virtual Lisp machine genera  at 10.0.10.2  (TODO: figure out Chaos network address s

Restoring the Heathkit Jr 35

Image
Heathkit Jr Electronic Workshop "35", Model JK-18 The Heathkit Jr 35 evidently had been stored with batteries in the battery holder, which corroded badly. I replaced it with a plastic RadioShack 4 D-cell battery holder (270-389), wired into the negative power rail and the hot side of the power switch (which is part of the variable resistor). Corroded battery holder Replacement battery holder mounted I mounted the replacement battery holder with a dozen "heavy duty" 1 inch foam double-stick mounting squares (rated to hold 900g), stacked in four groups each three high to overcome the various screws protruding through the main board. The remote speaker station The rubber foot used to protect the relay from being crushed when you turn the kit over was stuck to the remote speaker station. I put it in its rightful place. Relay with the brown rubber foot Earlier, I had built a couple simple circuits, which showed the meter and new battery pack w

FPGA selection for beginners

I'm not particularly expert on FPGAs, but I feel like sharing some of the thought process and research I did in getting into tinkering with FPGAs to help other people contemplating such things. Why FPGAs? FPGAs are the go-to solution for "digital things that can't be done with Raspberry Pi, Arduino, or other microcontroller plus software." If you want more than a handful of discrete digital devices in your project, an FPGA (or its smaller cousin, a CPLD) can be whatever collection of gates you need. From a more industrial perspective, they are a stepping-stone to the kind of large-scale digital design that goes into developing ASICs and high-powered DSP solutions. I'll probably discuss later some of the things that are probably not suited for FPGAs and assume for now you at least understand what they are, what they can do, and you just really, really want to use one. You want to buy an FPGA for good reasons and can't decide which: how to choose? Choo
