Note for NoV-64 users.



#6

Hi,

In the docs it's fairly clear that NoVRAM and NoV-32 can be configured in a Clonix-41 fashion. However, this seems not to be clear at all for the NoV-64. Of course they also can.

I should have properly pointed it out in the docs (my fault).

For those of you that may find this feature useful, just select "Clonix-D" in the configuration window and make sure you include the same ROM images in *both* "Flash ROM blocks" fields; plug your NoV-64 in the programmer and procced as usual.

Hope this helps.

Diego.

Dear Diego,



does this mean that you can use the NoV-64 module as a Clonix-D by simply overwriting the pages occupied by HEPAX?

Best regards

Frido

Well Frido, not "exactly". NoV-64 does not have the possibility of swapping its internal ROM banks as the Clonix-D does. So you can only have 6 pages (as in a standard Clonix). Thus the need to replicate the ROM images selection in *both* Flash ROM blocks.

Hope this helps.

Cheers.

I guess I'm not the only one that is somewhat confused about the differences between the Clonix, Novram, Nov-32, and Nov-64. It might be helpful to have a table comparing them.

Hi Eric,

You're more than probably right... as the "family" is growing up, its different members' features may lead to confusion.

Here you are an abstract:

Clonix-41:
It's basically a ROM-box which can hold up to 6 pages (4K each)
Intended to "clone" any ROM PAC module(s).

Clonix-D:
Same features that Clonix-41 but double ROM size. Its ROM is divided in two blocks of 6 pages each. These blocks can be swapped by plugging the module into an even or odd port.

NoVRAM:
A RAM-Box, mainly intended to clone "Adv HEPAX". It has 16K RAM and ROM to hold the four pages of the HEPAX module plus two extra ROM pages.

NoV-32:
Same as NoVRAM but double RAM size. Its 32K RAM are organized in two blocks of 4 pages each which can be swapped by writting h'000 or h'001 into a control word placed at address H'4100.

NoV-64:
Again HEPAX emulation with 4 blocks of 16K ram (thus the "64") and another two blocks of 16K ROM. Switching between the blocks can also be achieved by writing said control word.

Alternatively a new ROM (ICEBOX1H) written by Geir Isene, includes several commands in order to handle the ROM and RAM blocks of a NoV-64, allowing the user to switch between them from a FOCAL program.

NoV-32 is backward compatible with NoVRAM and Clonix-41, as NoVRAM is backwards compatible with Clonix-41.

NoV-64 is compatible with Clonix-D in terms of internal functionality, but it lacks the possibility of swapping its ROM blocks by changing the port. That's why it only shows 6 pages and they must be programmed in both banks.

Hope this clarifies a bit the differences.

Cheers.

Diego.
