Re: Electron ULA Schematics

That looks like a good start! Hopefully it will provide answers to those of you who are deeper into the function of the ULA than I have been. :)

The saga is quite the piece of social history, isn't it? ;)

Re: ZOMBIES ATE OUR ROADIES!

I think the UEF probably works fine in emulators and on real systems. It's just that my tools tripped up on some of the data chunks. You need to dig around in the files themselves to see any issues. I think BeebEm is adding two extra bytes to each data chunk after the CRC for the block of data itsel...

Re: ZOMBIES ATE OUR ROADIES!

The UEF file is a bit odd. It seems to include junk data at the end of each file block, so either my understanding of UEF files is incomplete or BeebEm is doing something strange. I can make a cleaned up version of the UEF if required.

Re: Games on EEPROM

Also, I'm still not sure what advantage this has over a ROM that contains 'pure' program code, and can be instantly launched by *XXXX ? Does it have to do easy porting from cassettes? Or is it something else? As I understand it, yes, it's the easy porting from cassette tape, the ability to load BAS...

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. :)

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.
