Both ALGOL60 and ALGOL68 are also available on the CDC Cyber 865 and CDC Cyber 175 at the Nostalgic Computing Center (http://www.nostalgiccomputing.org), and both are also available in the NOS 2.8.7 distribution with DtCyber in the GitHub repo at https://github.com/kej715/DtCyber. Pascal is available at those locations too. It’s not the original version written fir CDC Maxine’s by Wirth, but probably a direct descendant of it. > On Jan 5, 2024, at 4:02 PM, Gary Grebus via cctalk > wrote: > > On 1/4/24 19:34, Paul Koning via cctalk wrote: >> I think the CDC 6000 Algol 68 is still around somewhere.

[cctalk] Re: RIP: Software design pioneer and Pascal creator Niklaus Wirth
In further honor of Niklaus Wirth and Pascal: In a Poly-88 system I acquired last year, it had a printing of the Tiny Pascal Compiler article in a 1978 BYTE publication. That has BASIC source code for the initial interpreter of a Pascal compiler. We ported that over to the Commodore BASIC V2, as used on the Commander X16 system. As-is it only supported the INTEGER type (and arrays thereof). It compiles to a "p-code" where then an interpreter executes those results.The thing about the X16 system is we have BASLOAD that adds a few features to BASIC: long variable names, and symbolic GOTO/GOSUB so that line numbers aren't needed (effectively a kind of QuickBASIC front end to the native BASIC of the host system). It works splendidly at making it far easier to write up more complex BASIC programs. With the original TinyPascal baseline all working, now Martin Schmalenbach is taking the initiative of expanding the type support (including pointer support) and has a working "Version 1" that handles some simple input and output. We realize use of BASIC and p-code was never the most efficient approach to building a robust compiler and development environment. But we still consider it fun to use modern tools and perspective and pulling further on the threads of that 1978 article and see where it goes. It may be a helpful tutorial on the process of using one language to create another, then using that result to develop the language you really wanted (e.g. using tinyPascal to later write an on-system C compiler). Or it may be an example of a "super sized" BASIC program doing an interesting application (and exercising the multiple banks of the X16 system).

[cctalk] IBM 5110 IMFs
Does anyone here has an actual IMF file (Internal Machine Fix) for the IBM 5110? Not the file called "IMF" on the Customer Support Functions disk/tape, but a real fix. File type should be 23. I am trying to figure out how the patch mechanism works. The IMF is supposed to be loaded with the LOADER utility. Christian

Sounds like ALGOL 60, which suffered from similar problems. (Also no standardized I/O.) That was one issue ALGOL 68 corrected. paul
[cctalk] Re: Computhink Eagle 32 - software, docs, info?
Hi Chris and all - No video board, whether text or graphics Since thereâs no video board in the system, and a couple of cables internally that arenât attached to anything, I expect it was removed by a previous caretaker. This is sad because without one itâs unlikely to come up, not that anyone has found any software for it. On the other hand, there are zero PALs, so both full reverse engineering and maintenance should be straightforward. I've scanned the press releases and adverts that come up on Google and I'm going to wager it was meant to be used with one or two terminals. Nowhere do they mention a display, and the adverts show a box sitting next to a terminal. Send me a copy of the ROM binary please? W
