Comments on: 16bit Fortran … https://virtuallyfun.com/2010/02/07/16bit-fortran/ Fun with Virtualization Sun, 15 Jul 2018 07:15:39 +0000 hourly 1 https://wordpress.org/?v=7.0 By: neozeed https://virtuallyfun.com/2010/02/07/16bit-fortran/comment-page-1/#comment-1177 Sun, 11 Sep 2011 13:57:28 +0000 https://virtuallyfun.com/?p=195#comment-1177 In reply to Peter Dassow.

Overlays are key for small machines… Take the PDP-11 running RT-11 for example… It consumes 213 disk blocks.. which I figure is 109kb at least… It’ll run with 64kb of RAM, anything smaller well is too small.

I’d have to say the older Fortran version would have a better chance, I figure a hard disk will be a must for compiling, as you’ll certainly exhaust floppies for the source code alone..

But again if it has the ability to do overlays, I figure you can do it… What is funny is that I recall Microsoft Fortran for DOS needing quite a bit of ram for this thing… Funny how RT-11 can run it in 64kb!!

I know, there were binary versions of ZORK I-III for CP/M… but fun starts with rebuilding it for an older platform (you know this for sure already) 😉

True, but where is the fun in a readily easy to use solution?!? 😀
