I dug up old projects from the drawer.
A new revised version of the FlexiBridge and IDE-CF module I sent into production.

Almost finished a module RAM-Flash-Clock.
I'm a little caught a cold and I do not give advice to prepare files for production in this year.
I need some rest.

Short description of RFC module:
- RTC consistent with the project M.Gy. Enterprise Clock & Calendar (DS12887),
- sockets for two FlashROM and five SRAM (512KB each),
- both FlashROM can be replace by SRAM (configuration jumpers)
- possible to program 8 modes memory mapping (3 jumper M0, M1, M2) if I manage to fit, so much logic in the PLD (GAL 22V10)
- each chip can be independently off, including the RTC (dip-switch).

The most important change is a reversal of IDC sides.
This will make possible the back conversion of FlexiBridge to the classic bridge.
The rest is basically cosmetic.

With new version of FlexiBridge already yes.

These are the prototypes for now.
PCBs are large, so they are not cheap (approx. $ 15 apiece), but it is easier to make adjustments and look for errors.
Ultimately, when all of the blocks will work, I want all enclose in one large PLD.

PS. With this revolution, it's not as loud, because I could be in trouble

I previously suggested: forgot my complicated IDE card, and design new one directly for CF card. It is will more simpler and smaller.

OK, but is there any ready-made software for EP that can handle such a simplified interface ?

My IDE sw easy can be modified. Only the very low level I/O routines needed to be modified (simplified). Can be done under few days.

Could use a summary of the ports used by existing devices for EP.

10h-13h & 18h: Floppy Disk Controller
7Eh-7Fh:       Clock & Calendar
E8h-EBh:       IDE 16-bit channel 0
ECh-EFh:       IDE 16-bit channel 1

What else (serial card, EPNET, ZX Emulator, internal) ?
I would not like to do conflicts by creating new devices.
The 8-bit IDE-CF is needed eight available addresses.
