My ROM ripper/reader arrives tomorrow

Post by Colday »

Hi all.

When I bought a job lot of beebs (there's a post on the 'hardware' section somewhere) it came with an absolute load of ROMS.

Some were original and some were EPROMS.

Apparently the elderly gent that had them (and left them in his loft for the beeb's to get wet and rust (yes, it was the metal surround for the VHF)) was a developer for the standalone 'Info' desks that were left scattered about in various locations nationally. Onviously these ran on Beeb's inside the case.

Alas I do not have the big box they were in, but it turns out I DO have one of the beebs that was inside one of them.

Sadly it is the 'rusty' on and there is currently a thread on getting it working again.

Anyway, I am now looking to download/rip (or whatever the phrase is) and upload/post (see previous brackets) the rom images somewhere.

I have 35-40 ROMS with various version of this 'Info desk' software on (I have NO idea if ANY of them work or whether they were FUBAR prototypes).

But, where would you like them uploaded/posted to?

I was going to send them out for someone to do, but I thought I would learn about this stuff myself and then do it myself.

And here we are.

The EPROM programmer/access dubre arrives tomorrow. Hopefully I will have lots of lovely rom files to share very soon.
BBC's... I now have 6 9 10!
Including 1x boxed with manuals, unmolested model A.
And also an unmolested model B. (but not boxed sadly)
14x floppy drives (only 1x currently works I think) with a couple to test.

Attaching them to a post (or posts) in the Archive Submissions section of the forum would probably be a good idea:

Ok, these are not as easy to use as I would have hoped.

Has anyone got a TL866ii plus EPROM reader/programmer?

It seems to work ok, and I have read some ROM's but I'm confused over the supported chip list and how we work around that with a new programmer/reader?

Can you explain in a little more detail what you mean here. The programmer needs to know which chip it is reading to get the right signals on the right pins and the timing right. If you were programming EPROMs that would also determine the programming voltage.

I'm using the minipro program on Linux and that says the TL866ii supports 13,143 different devices.

The EPROM you are trying to read should have the device type printed on the top.

The ROMS's I have do have the things printed on the top, however the list of supported chips within the software doesn't find them.

I've tried reading with 'similar' chips, and they seem to read ok, but as the correct chip name hasn't been used to read the chip I have no idea if they are complete images.

I just wondered what other people do when the chip you have isn't listed?

Interested to hear about the Linux version, am using Ubuntu on my laptop in the workshop as it is somewhat quicker than Win10 on the aging hardware.

The linux program I have is a command line one. I'm using Arch and it's in the Arch AUR which like a ports system but it has the home page as https://gitlab.com/DavidGriffith/minipro You could also see if Ubuntu has a minipro package in its repository.

I have just noticed there is what looks like a graphical one too: https://github.com/wd5gnr/qtl866 I have not tried that one, though.

I made my own adapter board for a Raspberry Pi and less than 50 lines of python was enough to read an EEPROM by bitbanging. I was surprised by how simple the whole process was.

With respect to just reading the normal ROMs and the normal EPROMs as used in a BBC B, selecting any manufacturers 2764 will read the 8k byte (64k bit) chips. Selecting any manufacturers 27128 will read the 16k byte (128k bit) chips. You only need to match the middle part of the chips part number.

If you are not sure, select any manufacturers 27128 to read the chip.

Unless the chip is mounted on a carrier board. In which case a larger capacity EPROM chip will have been used. Modified BBC B machines can also use the larger capacity EPROM chips such as 27256, 27C256 (both 32k byte, 256k bit), 27512 or 27C512 (both 64k byte, 512k bit).

The export model of the BBC B (U.S. / German), the BBC B+ and the Master 128 can also use 27256 / 27C256 chips.

Again, with the 27256, 27C256, 27512 or 27C512 it does not matter which manufacturers version you use for reading.

Did you get sorted with reading these ROMs?

I’m pretty sure I could archive most ROMs with the hardware I’ve got access to (a bit-basher I made about 20 years ago for reading Atari carts, a proper eprom programmer, and a cupboard full of legacy readers at work)

Happy to have a crack if you want.

Surprisingly I only came back to this part of the forum today as I had another ROM question (other thread).

Thanks for the offer Jason, but I came to the conclusion that Mark gave above, that I can read them with any manufacturers version.

I also note the Raspberry Pi solution. I have a spare of those at the moment so may try that little project out.

Speaking of which I really must finish off getting that BBCFDC and Pitube stuff sorted. I have a 100% working floppy drive guaranteed now and a clean new floppy disk direct from Retroclininc, so at least I can do my own testing to ensure it is all working as it should.
