Looking for a Guru ROM upgrade for GVP HC8+

I would like the above to be able to use the entire 18GB of my drive, instead of the usual 3.77GB.

Any revision would do, as I can use my eprom programmer to update it if necessary.

Regards and thanks

the latest rom is further down

http://babel.de/download/gvpscsi4.tar.bz2 is the Binddriver driver of the GURU.ROM (you need to boot from another card, then add archive above saved in the EXPANSION drawer).

That or grab a real Guru.ROM. Notice they are (very) hard to show in sales threads.

I'm currently using an HC+8- controller with an GURU-ROM 6.11 on it, which will have to search for a new home as soon as my new accellerator card arrives -- my current accelerator (which I also want to sell here then) has no SCSI on it.
So, if you take the ROM together with the card, I'll have one for you in 1-2 weeks, depending on an appropriate offer per PM.

Hi PM on its way to you

Getting and programming the ROM(s) are easy. The CPLD adapter board is harder. I asked if I could re-make them a few years ago and Ralph said that he did not want to devalue existing stock. Perhaps it is time to ask again?

Not heard from Cameron after my PM to him earlier this week, so if anyone has a GURU ROM that they want to sell to me, please let me know.

thanks

In between, several thing happened.
In short (and to follow the rules?): PMs sent and received, payment sent, payment received, part shipped! :D

alexh: Do you have any idea what the adapter-PCB is good for? There's a GAL below the ROM itself, what does that do? I've read something about extending the address space, but I can't imagine that a GAL can connect more address-lines than available on the socket..?

But however, yes, it seems like it's time to ask again! :thumbsup:

could I ask what the difference between the guru and the latest official is, in term of support of drives and whatnot?

Of course you can, but since I've never used an GVP without an Guru-ROM, nor an A2091 with Guru-ROM, I've never had the opportunity to experience any differences myself. So for me, there's just the information left that it *should* be better in indirect transfers to 32bit FastMem on Zorro-II and *should* be able to handle larger disks. Now that I've sold the Guru-ROM, maybe sometimes I'll burn the normal GVP-ROM and try it out.

But back to the adapter: Can anyone imagine that it's more than an unusual kind of copy-protection?
