P.M.F. Barcode Reader

Post by kieranhj » Sun Jan 17, 2016 7:17 pm

Hey all,

When I bought my Master it came with a barcode reader by a company called P.M.F. that connects to the user port. I have no idea if this works or not but seems to be a bit of an oddity. It comes with a ROM for the software. Before I put this on eBay is anyone here interested for the cost of postage? I am blatently not going to use it so would rather it went to a fellow *. member.

Cheers,
Kieran

It's one of the few Beeb gadgets I've never played with so yes, I'll take it off you if that's ok.....?

These are good fun. Using the supplied software the master can read the barcode on a tin of baked beans! :lol:

I had one of these, and I found it absolutely awful!
I don't know if it was faulty or not, but you had to maintain a perfectly constant speed across the barcode. The barcode had to be on a perfectly flat surface, and if you were lucky it would register it once every 20 tries :roll:

I've just bought one of these barcode readers, mainly because I've always wanted to test it out with the code printed in the back of Bruce Smith's BBC Micro ROM Book.............
s-l1600.jpg
Bar Code Reader Project - Cassette version
However, as you can see, the particular version of this kit that I've been able to find has the software on cassette tape, and I don't have a cassette player these days. I decided to draw a line at using old tapes, having had more than my fill of hassle with them BITD.

I'm just wondering whether anyone out there has the disc version of this software? A ROM version is also mentioned in the original post on this thread. I've hunted around the net, but I've not been able to find any archived copies of this software online. I did find a circuit diagram for the barcode reader itself, however, which may be of interest to someone - https://acorn.huininga.nl/pub/docs/circ ... 20Project/

If anyone out there has an SSD or a ROM image of the bar code reader project software that they could share, then I'd be very grateful. Otherwise, I'll just have to cross my self-imposed line, and buy a cassette player, sigh :roll: It's funny how one purchase leads to another in this retro computer hobby......

I did have a play with this after Kieran sent it to me and although I can't rememeber how I drove it software-wise (I've slept since... :roll:), I think I must have the used the rom so I'll endeavour to dig it out and make an image. If I can find it reasonably quickly tonight then I'll post it later but if not, it may have to wait until next week.

^ If you like (or if diff from Martins 'driver') you could throw just the tape in a flat box, 2nd 60p stamp and post to me so can archive it :wink:

Then I can throw out back window when done :lol:

Try this. :wink:

Edit:
Disk image updated to run from the $ directory using Shift-Break. Thanks for pointing out the error, billcarr2005. :oops:

TITLE further modified to work with BBC Master computer rather than the BBC Micro only.

Thanks for the offer! I’ll send you the tape for archiving, if I may? I won’t be able to check if it differs from the SSD tho’, but perhaps it ought to be archived for posterity anyhow? :)

Yes it would be good to see if any differences from disc version, so PM on way soon. (So can scan more than tinned beans John :lol: )

As LP tapes had more remixes as could do 100mins, & CDs where only 70mins, now 80mins.

Here you go, courtesy of 10 seconds with UPURS..... :D

Note that I dumped it as a 16k rom (the physical device I have is a 27128) and that image is attached but on inspection, I can see that it is actually only an 8k rom and so the attached image could be split in two and programmed into a 2764 or similar 8k x 8 device.

Fantastic! Many thanks Martin - that’s very much appreciated :) I’ll compare and contrast the disc and ROM versions of the bar code software.....

I've now had a chance to try this barcode reader, and it's been a mixed experience!

For some reason, I've had a lot of trouble getting the files from the SSD onto my HxC Gotek (the SSD works fine in BeebEm, and looks fine in DFS Explorer, but the files are corrupted on the Gotek). In the end, I put the SSD on my (working) A5000, then used !BeebArc to extract the program files. I was then able to load the files from the A5000 onto my Beeb via Econet. I did try copying the files over to disc, but I ended up with errors when using TreeCopy, CopyFiles, and even just loading and saving individual files directly. Anyhow, the programs all run fine across the Econet. I suspect the programs on the supplied cassette will be identical to those on the SSD, but I've sent the cassette to Col for archiving, just in case.

So, I found that the Decode, Picture, and Music programs all work quite well. The BCBASIC program, however, was much as Lee described his experience above, and I've not found any tins of beans that scan successfully with the EAN program, alas! So, I don't think I'm going to get very far with the ROM Book code, but there's still some potential for fun with this device.

Lastly, I've been able to load MartinB's PMF Barcode Support ROM into SWRAM (after chopping the file in two, as per Martin's advice) - this looks quite interesting, but it's purpose is somewhat mysterious to me as this ROM isn't described in the Bar Code Project documentation that I have. The ROM *GRAPH command shows the barcode reader output on a nice chart, but the usage for the other commands isn't obvious - it's also hard to know whether one isn't using the ROM commands correctly, or the reader is just being flaky! I've attached an 8k version of the ROM, just on the off chance that this will be helpful to someone....

Thanks again to everyone for the help in getting up and running with the barcode scanner :D

Strange that. I found the EAN software to be very robust when run from floppy disk on my Master. It read all barcodes I threw at it.

It does only read the number, though. :wink:

Many thanks for this Col - nice work!
As an aside, I have now successfully scanned one barcode with the EAN program - a box of Sony DD 3.5” discs! Woo hoo! :D
