Uh....is that all there is to it ? Thought the 2532 also needs a negatieve power ?
If so, this will work with any programmer....

Pfffff, checked the datasheets of both 2532 and 2732 and yes, both only require the +25V programming supply....no negative supplies. Building an adapter like that is a no-brainer, so that leaves only the obscure 08 unsupported but there are plenty of ways to use 2716s instead.

So funny as for all the negativity on the UKvac forum I had almost dropped the idea of getting one and was now fiddling with the ancient laptop that Etienne gave me again....(which works nicely by the way, the only real trouble is that you will have to transfer the files through floppy to a PC that supports Internet.....
I was already thinking about a way to hook up that laptop to the Internet somehow using an Ms- DOS browser....(yes they exist).....

OK, Im back to square one. I want the Batronix, anyone interested in the Needham EMP-10 ?
(with supporting laptop if Etienne doesn't object to it ;);) )

P.S. THANK YOU ROBIN !!

Thanks Robin, i will try the adapter when burning my DK Roms

Andre, I have some questions:

Is a 2708 eprom the same as a 27080 eprom?

What do you think about this one: http://www.mcumall.com/comersus/store/comersus_viewItem.asp?idProduct=4225

I have doubts buying one where I need to make an adapter for 100+ EU, but I don't really know enough about it to make a good decision.

All I know is that the Batronix is fine for my MK2 revision roms, but it's not for i.e. DK

The one you link to is a "Willem" programmer and I hear very different reports about them. Some say they work fine, some say they suck.....

That adapter is not going to cost 100 Euro for sure !

Oh and no a 2708 is a really ancient EPROM from the time of B/W games like SI

27080 is MUCH later and bigger....

I mean the device cost me 100+ and I need to make some adapter myself risking to blow it up

The first thing I want to do with it is OK, I have the needed EPROMS to programm 4 different MK2 revisions.

On the other hand, I don't want to buy some Chinese crap.

I think about it and get back to you.

ISD there any change we will get 5 people to buy one?

One more question about the adapter: how does the software/ device know you'll be programming a 2532 or 2732 eprom if not supporting them?

You just cheat and tell it that it's a 2732 :)

Although its always best to enter exactly the right brand and type, the parameters will differ only slightly per device. There is always (at least in my Needham software) a way to select "Generic" types and so far this has worked fine for me.

I could build two adapters of course, that is, if I decide to get one.....

Because of a good discussion about this subject on the UKvac forum I was triggered to have another look at my current situation.....

I kinda left the Needham project after having experimented a LOT to get it running under some version of Windows, so that I could have USB support for a. USB memory stick or even Internet access. this was on a laptop I still had around and fixed with a screen from Etienne. However, I never got it to work reliably with that set-up. So, yet again Etienne came to to the rescue and have me a ancient Toshiba 1910 laptop (is that the year of release ? ;);) ) to give that a try. It basically ran Windows.....95 or 98 maybe, but the basis was DOS.

I actually reformatted the HD and installed just DOS. And apparantly that's where I left the project.....
So....I downloaded the latest Needham EMP-10 software and copied it to a floppy. I first thought I would have to use my current (work) laptop to hookup the USB floppy drive, but to my surprise, OS X still supports floppies via a USB drive, so that was one big hurdle less for me.

ALso I was a bit worried that the Toshiba's internal floppy drive would be DD and not HD, but it worked just fine. Connected the Needham and started the software. It recognizes the Needham without problem, but this also worked with the Windows machine I had tried before.....

So, now I still have to test the set up, will do so tonight. If this set-up is working reliably than this is surely workable for me. The only hassle is exchanging ROM files using floppies and of course the extra laptop itself, but it's surprisingly small and boots up lighting quickly with DOS ;)

Its indeed small, but why not keep that for "mobile" services, and just hookup a pc under the workbench ?

so much easier with a big screen for internet while working
just make it dual boot, or perhaps dosbox supports passthrough parallel ?
I know VMware does, so you can always run vmware and dos inside, that saves rebooting for burning  ;)

It's always better to talk things trough before just buying stuff, I'm already happy we discussed all this :)

I hope for you this will work out just fine with your current setup.

Yeah I guess my old PC will end up there BUT, the problem is that this is probably too fast and/or the parallel port maybe not a "true enough" parallel port for the Needham, even if I'd run totally under DOS.

it's not like I read/program EPROMS everyday so I think if the Toshiba works Im happy.
My old PC still has a floppy drive too and of course I can hook that one up to Internet without much trouble....

...and that Tosh is kinda neat, very retro....
