Re: Today I Received...

A little while ago, for my 74th birthday I received : 1/ I discovered recently that there was a japanese company that still made slide rules (especially circular ones), and I always dreamed of such a device : here it is, together with my original "computing device" that I was offered for X...

Re: sQLux v1.0 (The Xmas Turkey)

Here is a new version of my CONWAY_DPF file for superForth, sightly modified to add a word "bench" to compare runtimes with or without plotting : : .< 0 <# #S #> TYPE ; : >< ( n,a,b --- [a<=n<=b] ) >R OVER <= SWAP R> <= AND ; CR CR .( Conway's life in a ) 120 DUP .< .( x) DUP CONSTANT ww (...

Re: sQLux v1.0 (The Xmas Turkey)

I shared my Conway program here : https://qlforum.co.uk/viewtopic.php?f=3&t=215&p=1438&hilit=conway+superforth#p1438 Tomorrow I will try to add a "word" (in the FORTH sense) to benchmark it with and without plotting. To play with it, you will have to install first Digital Preci...

Re: sQLux v1.0 (The Xmas Turkey)

Here I show two screen shots of what I get on my Pis on a 1680x1050 display : First with sQLux, 'WIN_SIZE = 2x' in the .ini file sQLux.jpg Then with uQLx, with the command 'xzoom -mag 2 3 -source 512x256' uQLx.jpg Both emulator windows are exactly the same (and circles are circles !), but on the uQL...

Re: sQLux v1.0 (The Xmas Turkey)

Hi all ! As one of my two QLs is no longer booting and the other one is still confined in the Alps, I decided to fall back on emulators in Raspberry Pis. I have a Pi Zero W running an old raspian, that I use for QL emulation with uQLx (and also for a Ceres-Oberon 1984 workstation emulator which I li...

Re: New "feature" (aka "bug") in both ComputerOne and Supper FORTH :

Hi, Which is the best Forth to use? The question is : on what machine and for what ? Classic FORTH machines were 16bits on 64Kb (or less) memory, and could be (and were) metacompiled for almost all processors, following basically very similar models (norms : 79, fig, 83...). What this programming e...

Re: New "feature" (aka "bug") in both ComputerOne and Supper FORTH :

That I am not interested in assembler does not mean that I did not. My first "personnal" computer was a SCMP elektor kit that you could only program with machine code through a hex keyboard, my second was the elektor so called "game" computer with a Signetics 2650 CPU to program ...

Re: New "feature" (aka "bug") in both ComputerOne and Supper FORTH :

Typically, the FORTH machines adopting the norms up to FORTH83 were 16 bit machines in a memory space of 64Kb (or less). They may be metacompiled with the help of a FORTH macro-assembler for the FORTH engine and all the low level and hardware dependant primitives. Stephen Pelc at MPE did it this way...

Re: New "feature" (aka "bug") in both ComputerOne and Supper FORTH :

ComputerOne is a company that sold in the eighties software products for the Sinclair QL. Surprisingly, some of their product (like their assembler and a monitor) are today PD, but not their FORTH, because apparently nobody knows who owns the copyright. I was lucky to buy one in these times and I fi...

New "feature" (aka "bug") in both ComputerOne and Supper FORTH :

Before digging into the machine code of Supper FORTH, I wanted to test my new "Folly" program with ComputerOne FORTH. The issue being how to port its simple looping construct "...TIMES(...)" to SupperFORTH. To sum up : IN FORTH the "DO...LOOP" expects two parameters on ...
