!newlook probably contains a !Boot file. Shift-double-click the application to open it up and see what it contains.

Re: *now solved* help needed with Quill

If you have a disk with the tape versions of the files on, you can convert it with the SSD2UEF.py tool from this repository. It depends on a couple of other Python modules in that repository so it's not a standalone tool.

Re: *now solved* help needed with Quill

I'm sure you know what I was getting at, but I should clarify for others. ;) What I meant was that, in the cases where files are just loaded into memory, you typically have more memory available on tape-based systems because you don't lose memory to things like filing system workspace. It seems to m...

Re: *now solved* help needed with Quill

Sounds good. Usually things from disk will run fine from tape as long as they don't want to read and write from multiple files at once or do random access. Memory is easier with tape, too, so *LOADing and *SAVEing will usually get you close to where you need to be. :)

Re: help needed with Quill

Is the P.flyer file on the disk needed? I'm guessing that the ZAOR image isn't used at all. In which case, if the load order is

Code: Select all

$.LOADER
$.ZAORCV
$.INST
$.BIBM

then I can make a UEF for you right away. :)

Re: First word plus to PC

I wonder if places like the Centre for Computing History have considered setting aside a machine for members of the public to use for transferring files from old disks. Ideally, you would hope that this sort of service would be something that local libraries could offer.

It's probably better just to link to YouTube videos than embedding them as Flash objects. Some of us have disabled Flash in our browsers and it's a format that's going away, anyway.

I think the game was quite popular on both the c64 and amiga. A game with poor sales figures on either of those systems still probably outsells a 1988 BBC/electron best seller.
