RiscLua802

RiscLua801 was compiled for use with newer ARM CPUs, that support VFP. At the request of Richard Wheeler I have also put out on my website a RiscLua802 for those who have older machines or Virtual Acorn, that do not support VFP. Its binaries, lua54 and luac54 are rather large because they are AIF files already statically linked with UnixLib. The reason for their naming is that Lua 5.4rc2 has just been announced, with hardly any changes from rc1. If no serious problems emerge, it is likely to be the official Lua 5.4 within a week or so. RiscLua801 and RiscLua802 are functionally the same.

Not having an Iyonix any longer I am not really in a position to test RiscLua802 properly. I would be grateful for any feedback from those who do.

Thanks for supporting obsolete CPUs. I can’t justify using anything better than an RPi Zero with RO. otherwise it’s mostly wasted hardware features. Mostly. Mid 90s I got used to having an FPU.

Richard was having problems with RiscLua802 so I put up a revision which is no longer statically linked with its C library. And he says it works.

I can’t justify using anything better than … mostly wasted hardware features.

I am intrigued by this position. Waste has been the driving force of our society, at least until a month or so ago. But it turns upon the rather dodgy belief that we know the proper uses of a thing. What is waste? What is economy?

By the way. The latest zips of RiscLua on my website contain a new Weave library. Weave version 4 has ceased to be a separate application but has reverted to being just a Lua library. It is far more compact and simple than previous versions. I recall that Archive magazine carried a two part article by Harriet Bazley, Weaving Your Website, in May/June of 2002.

Waste has always been something which at best irritates me. TBQH a lot of what I own is secondhand, recovered, reused, or “upcycled”.
In the case of the Pi 3. It’s sitting here currently being used as my RO machine because I had to dismantle my Pi Zero based one so I could measure and model the boards so I can design a case that holds the Pi Zero, the PCM5122 DAC module and the 3 USB / ethernet hub board.
The Pi 3 is using more power even sitting there idle. It can’t utilise it’s WiFi, BT or the DAC board it has IN RO.
My current “Daily driver” PC is an nVidia Jetson Nano. Unfortunately I’ve had to power up my PC recently to use Fusion 360.

Back to Lua. I’ll grab a current update shortly. Thanks for the heads up on the additions.
