Re: Digiac 2000 MAC-III 6502 trainer

Just as a quick update, I was very kindly sent the various boards mentioned above including the EPROM and I have now got the monitor working. I need to write it up and take some pictures. Unfortunately I don't have the means to read out the EPROM image at the moment.

Re: Digiac 2000 MAC-III 6502 trainer

Hi All.

Thanks for the advice, I’ll PM the Rom image to those interested when I get a minute.

If you PM your address to me James I’ll post the EPROM on to you, I’ll include the Applications Module too as I’m sure I’ll never get round to using it.

Thanks again All & sorry for late reply.

Cheers ...

Re: Digiac 2000 MAC-III 6502 trainer

That's great news!

On the copyright front... I'm sure it is true that the company own the copyright although at the same time when I contacted them they seemed to have no real memory of the device at all, let alone any kind of continuing commercial interest (eg they did not offer to sell me a new ...

Re: Digiac 2000 MAC-III 6502 trainer

Hi All.

That all looks very interesting, I’ll have to sit & have a read of it when I get the time.

I too was surprised it was dated 2005, I suspected late 80’s to early 90’s?!

Got some news on the programmer front, my work has kindly given it too me as they no longer have use for it!

I think it ...

Re: Digiac 2000 MAC-III 6502 trainer

Hi

No problem at all, more than happy to help if I can & hopefully learn something new myself while I’m at it.


Here is a link to what I got hold of. Unfortunately is a bit sparse although the brochure is quite cool:

Re: Digiac 2000 MAC-III 6502 trainer

Hi guys

Thanks so much Pete / GrubZero for the post and the offer of help

If you can dump the EPROM I'd be dead keen to try it in the board I have. I have powered it up and got a red light but nothing else.

I have got some documentation from the original supplier including manuals, and so far as ...

Re: Digiac 2000 MAC-III 6502 trainer

Did you ask the company if they have an assembly listing for the monitor or even a binary or hex file?

You could always reverse engineer it to find out the memory map and how the peripherals are being access, then port over a simple monitor. A lot of folks around here have written their own and ...

Digiac 2000 MAC-III 6502 trainer

Hi all

I've just got hold of one of these from a flea market. It's quite a nice thing, part of a larger set of boards used for training. I've been able to get a bit of information about it (manuals etc) from the manufacturer who are still going. However the main problem is that the monitor EPROM ...
