The Cambridge ABug software hacking/archiving thread

In another thread.....

This is a great opportunity to archive some of these rare missing items [-o<

In the absence of a game-hack-guru, there are some utilities that do a good job. (DISC DOCTOR'S "*TAPEDISC") and a number of ready made tape copiers.

Also - for a lot of software, this may be enough

*TAPE
*OPT1,2
*LOAD""1900
you will see "FILENAME" LENGTH LOAD-ADDRESS EXECUTION-ADDRESS
*DISC
*SAVE "FILE1" 1900+LENGTH EXECUTION-ADDRESS LOAD-ADDRESS
TAPEDISC.jpg

This will often be sufficient as you aren't trying to get the game working - just get the files.....
JUST GET THE FILES... :lol:


Any help here would be greatly appreciated.


I'm willing to dedicate a bit of time to get this done if you guys can make sure I have the tools to do it!
There are 39 games in the list, 21 on cassette , 9 on disk, 3 on cassette/disk and 6 unknown.

What will be the optimal way of getting this done?

Cassette:
I can take a desktop pc with a line in socket - what else will I need (software) to get the files from cassette?

Disk:
What are the best tools to use to copy floppies? Would UPURS be enough? I'm sure the centre will have several 5.25 inch floppy drives I can use.and I've got a load of 3.5" floppies I can copy onto if needed.

Will anyone not attending the event be available for online assistance?

Don't know about tapes - UEF seems to be the route here.

For disks I use ADI and ADT. However, with discs, the protection may be such that one has to unravel the protection first to have a method of attack. In the educational arena Sherston titles are a case in point as they use a sector with a bad CRC.

There is also the problem of ADFS disks, though they tend to use similar protection methods to DFS disks.

Although I am not attending the Cambridge meet I should be happy to offer virtual advice. :D

If you want to capture the audio from the cassettes as WAVs on your laptop, I'm no expert, although I have done it in the past. I used Col's somewhat terse instructions here:

There, Col suggests connecting the tape recorder to Line In on the PC/laptop and using WaveLab to record the audio with settings of "Stereo, 44k, 16bit, peak about-2.5", if that makes any sense to you!

The audio will have to be converted to .UEF later, but the main thing initially is to capture the WAV. The problem is, I did have one experience where the audio seemed to be captured fine, but I couldn't successfully pass it through the rest of the toolchain that you use to convert the WAV audio to a digital tape-image -- I was converting to .CSW, but you can also convert to .UEF, etc. -- and you can't tell at the WAV stage whether the captured audio is good or bad. That's why I'd prefer Lee's method, which you quoted above, which is to use an actual Beeb to load the files off the tape and then save them to disc -- and perhaps then from disc to your laptop via UPURS. (Though you might run into problems with locked files or other tape protection methods.)

Any thoughts?

Is it worth calling ahead with the list of box numbers to get them retrieved? It could easily take half an hour to find and unpack a box, and there are at least twenty boxes mentioned. If you can get one person started on the copying and have a second person scaring up the boxes, unpacking and repacking, that would be better.

That all sounds good. I'll be using a master which has UPURS and an sdcard based hard disk.
I don't have a tape recorder (my dad might have one) but there will probably be one at the venue, I'll check with my dad and report back here. I definitely don't have any cassette cables. I might give Jason Fitzpatrick an email to ask him what equipment I can borrow whilst there.

edit: That's a good idea Ed, I'll mention it in my email.

If you prefer using the command line on a Unix-like system, the rec tool that is part of the SoX utilities can also be used. Something like this should output a stereo WAV file to a file called output.wav:

Code: Select all

rec -c 2 -r 44100 output.wav

You might need to play with audio sources and levels to get a decent recording, but it does give you an indication of the volume as it records.

Can you say something more about the toolchain you are using? (I've probably already asked this before.) :roll: :D

I'm setting off at 9am on Friday morning so should arrive early Friday afternoon so should get a good 8 hours to spend on this.
I think I'll produce wav's regardless as long as I have more than one tape deck I can set one away producing wav's while I try loading and copying each file individually on the master.
Does anyone have any info on dealing with locked files? I'm sure it was printed in one of the magazines bitd.

It was a while ago, so I don't quite remember, but I think I used GoldWave on a Windows 8 PC to record the audio off the tape to WAV, and then possibly fiddled with the audio in GoldWave to squash it down to mono,* and then used CSW Viewer (which happened to be on a different PC, for some reason -- perhaps because I thought I needed Win XP) to convert the WAV to a CSW tape-image file. This was all mostly based on Col's advice.

I think there's a special hacked/patched version of BeebEm (from BilCarr?) that can load .CSW files.

:idea:

* Actually, I might have recorded straight to mono 8-bit WAV (as per the CSW Viewer instructions):
http://stardot.org.uk/forums/viewtopic.php?t=8584&start=30#p112189.

But Col's technique is more sophisticated:

Here's the tape file unlocker program for a Model B:

  5*FX13 4

You might need a different assembly address on a Master (see lines 10 and 100) -- but I'm not totally sure.

OK, I will bring my cassette player and cable to connect it to the BBC Micro. I also notice that the museum sell floppies, so I am happy to buy a few if needed. I have a BBC Master, though I don't officially have space for it. I might put it in the car to see if I can squeeze it in, but if not I expect there will be others there!

Check this thread for floppy-to-floppy copying tools:


Ripoff IX is 8271 only, but easy to use. It can copy some but not all protected discs.

The ADI ROM is more sophisticated and can work with the 1770 disc controller as well as the 8271, I think. (But note that some protected discs can apparently be copied with an 8271 only.)

Don't use laptop 'line in' as it ain't, it's MIC only, unless you have a old 486lappy, but they hum like mad, & useless
Don't use USB audio boxes to laptops either, very bad quality, would not even record a old 78rpm 10" vinyl without hum

most will need fast forwarded, then rewound to slack them off first, especially 'black tape'/ carbon monoxide tapes as these are a utter pain, 'brown' should be ok..... until it squeaks & winds up /stops!

sometimes need to tape to tape first with Hi-Fi decks, NOT alba cheap rubbish decks, bin those

once setup, don't record with Audashity or Gold wave free progs utter bloody useless, check pics elsewhere of rubbish output.I will NOT except these, utter waste of my time.

Hmm. Worrying. I have had some success with Goldwave and a cassette recorder, but it was connected to a PC. Maybe it would be good if there was a PC with a decent soundcard on hand then?!

Or maybe Peter's had good results from his USB cassette recorder in the past..?

On the question of USB interfaces that's a bit of a sweeping generalisation, surely? My understanding is that the silicon for a decent audio A/D is pretty much a comodity so much depends on the quality of the analogue circuit design. I am sure there is indeed plenty of crap out there but something aimed at a home recording enthusiast rather than just for use with Skype might be perfectly usable.

CMcDougall wrote:most will need fast forwarded, then rewound to slack them off first, especially 'black tape'/ carbon monoxide tapes as these are a utter pain, 'brown' should be ok..... until it squeaks & winds up /stops!


On the other hand chromium dioxide tape, which is one variation of "black" tape looking a slighly bluish black retains the signal much longer than the brown (ferric) tape, somthing that was really noticable when I went back over my tape collection from the 80s. The other kind of "black" tape, cobalt-doped ferric, which is actually a very dark brown, seems somewhere between the chromium dioxide and the ferric in terms of data retention.

CMcDougall wrote:sometimes need to tape to tape first with Hi-Fi decks, NOT alba cheap rubbish decks, bin those


This is intriguing. I saw an article recently that suggested that a phase shift could throw things off. I wonder if reversing the phase of the connections or even just inverting the wave/apply a phase shift in software would suffice.

It's a pity I didn't sign up in time. It might be a sledgehammer to crack a nut but I have an RME multiface on my home PC. Another tool that might be used is one of those portable flash recorders. Not a dictating machine, something aimed at location recording. The one I have is a Zoom H4N but there are plenty of others out there - does anyone going have something like that? You can record from the line out of the tape deck to a WAV on an SD card and then process it with whatever you want.

Don't think anyone has suggested it (there were a lot of posts and I might have skimmed it!) - for the tape titles - worth posting the first WAV/UEF somewhere (might be too big for *.) that non-attendees can have a quick check.

I have visions of some poor soul doing 8 hours of recording and then finding all useless ... so maybe do the first one and then get it checked to make sure all settings, cables, etc. are right and the recording is usable?

If too big for *. then maybe a good idea to find a place that can be used before the first tape is uploaded.

Good luck anyway. :D

FLAC compression is lossless. On music it typically almost halves the file size. Never tried it on a BBC tape image but, as I say, it is lossless so perfectly safe it is just a question of what compression level it would give.

I am not suggesting as an archive format, more a way of transferring WAV files so somewhere else. There are other lossless formats but FLAC is open source and cross platform.

What testing would one do? For a WAV (or FLAC equivalent) presumably it would be sufficient to play it into the cassette interface of the target machine and check it loads. Presumably that could be done on-site too but if the files are made available "live" that does allow others, not there, to help.

if someone could do tape to tape with good hifi decks, this would be ace , but don't use high speed dubbing or poor blank tapes, I always use TDK D90s, these stand the test of time, hence all my illegal rave tapes from 1988 to 1994 still exist & uploaded on all oldskool rave sites (ultra rare, again only person still with them :mrgreen: )

hope most just work tape to disc using good players like a Sony hifi Walkman, think mine is actually now dying with everything thrown through it :lol:

Forgot to mention, some old tapes will need recorded first (ie Atom) & also untighted the screws to stop squeak or auto stop kicking in :evil:
some may need put into another tape shell, this is the only way to go most times with those.... 8)

hope you find them in the boxes, as last time Dave/Kees/Wim , the Atom MIA tapes have walked :(

I have a cassette player, a laptop and a bbc master. There is a lot of advice on how not to make WAV recordings, but I am wondering if there is anything i can buy relatively cheaply that might help get the sound from the tape to the computer...

I'm not sure that there is. It all seems to revolve around having high-quality cassette decks and Line In sockets.

If you're trying to record audio from tape and you're not a seasoned capper like Col, then I'd echo what Richard said above and suggest trying to capture just a single file first, and see if that works -- either play the captured audio back into a Beeb, or convert it to 8-bit mono WAV and then to CSW with CSW Viewer (which needs to run in Win XP (perhaps in a VM), I think). (CSW Viewer is the only tape-image creator I've had any success with. The .CSW files it generates can be loaded straight into BeebEm ("Load Tape").)

I wonder if using your Master+hard disk might be the best approach: hopefully you'll be able to borrow a cassette recorder, and then use Lee's method of *LOADing from tape, and then *SAVE to your hard disk. That way, you can run the saved programs off hard disk and you'll immediately be able to verify that the copied programs work (or at least that they're intact copies of the originals that can be got working on disc later ("JUST GET THE FILES"!)).
