there are a lot of skilled individual genius trying to create the definitive "All in One" card
From my point of view: I did not set out to create an all-in-one card, I set out to create a network card made using "hobby friendly" electronics appropriate to the 30 year old Enterprise, so no little tiny surface mount chips, no magic programmable devices, just big old-fasioned chips. But when word got out about EPNET the constant feedback I heard was "more RAM", and then I heard Compact FLASH had an 8-bit mode... So it wasn't a case of "shall I do Compact FLASH or SD": CF was almost free and easy, SD wasn't. So it became a multi-function card.

And there has been more group work than you have seen on the public forum: lots of expertise (and even source code) from zozo on EXOS/EXDOS/Enterprise and lots of expertise on the internet/TCP/IP from lgb, for which I am thankful :ds_icon_cheesygrin:. Group work would be a lot easier if we lived in the same country! :roll:

Soon I will need help with something else: the User manual is ~50 pages, all in English...

Of course, I offer myself for whatever you want, it could even be translated to several languages just as was done with the EnterMice Wiki.

This topic has made me wonder...would there be any demand for EPNET without a network module? :lol::lol: :lol:

So: 64k/128k FLASH for putting ROM images into, up to 512k RAM*, Compact FLASH mass storage.

The network module costs around 25 GBP/8800 HUF so it would be that much cheaper.

B.

* 512k total "ROM"+RAM  so: 512k RAM no ROM; 448k RAM 64k ROM; or 384k RAM 128k ROM. You need EXDOS in the ROM to use the Compact FLASH and that takes 32k

Ram/Rom and Mass Storage are the higher priorities for an user, I think, so  a cheaper upgradeable card can be also a big success.

SD is the ideal, but there are CF to SD adapters that can suit us.
Also exist a direct SD to IDE adapters.

Directly an IDE disk is nowadays difficult to find
I have least 100 :-D

and less useful than a CF.
Yes, mostly because it is need a external power supply. For a memory cards possible use 5V from the interface card.

On the other side, the SD is constantly evolving, there are a lot of formats, SDSC, SDHC and SDXC only compatible backwards.
These are only software differences, the Enterprise SD interface compatible with all, also including MMC.
