We also had a kaypro & LADDER but only ONE, so we made one (the game, I mean :-) from scratch. We made it in PASCAL using ONLY standard features (well, of course we DID have to use a few EXTERNs for video output), so that we got it to work also on the DEC-20 under TOPS-20 using PAX (the Pascal compiler people at TeKoLa had made) as the compiler. The main target then was an Ericsson Step/One PC (it was actually Panasonic somethingorother, an MSDOS machine anyway...) and it worked BEAUTIFULLY (this was 1983, I think)! I think I did quite a few bits of the work, but I ain't sure who did what. Anyway, when I moved down from DEC-20 to PCs (I went to work, instead of hacking at the computing center anymore :-(, I got a IBM compatible and changed a few bit & pieces to get it working on an IBM XT. The compiler was MS-PASCAL (a version BEFORE 3.20 or something like that) and the year was 1984. After that I have given the binaries to anybody who asks, but I've never had time to make any changes (there has also been no need for them...). I think I can still find the source if somebody is interested, but I think it should be converted to C (it ain't big... REALLY). The end result was an ALMOST EXACT copy of (look-and-feel, you know) of the LADDER on Kaypro. We even looked at the screens on Kaypro and used them as a startup screens, but we DID make some new ones as well.. The screens are kept in a TEXT file (like in WANDERER), so making new or changing existing is trivial... jpk - JP Koivisto --- EMail: jpk@davasun.data.nokia.fi PS. I added comp.sources.wanted to 'Newsgroups' as I DO HAVE SOURCE!
