EclaireXL

Does the rest of it work, just not the menu?

Do you have a logic analyzer? I can outputs some signals on the gpio for debugging.

Do you have any technical documentation, schematics etc?

Perhaps we can test it by poking/peeking regs from basic...

no, i dont have a logic analyzer or the schematics...
let me see what info i can gather

Nir,
If you power on eclaireXL and go to Basic, after keep down the start key and simultaneously press and leave the F10, after the IDE2+ menu appears?

no it does not, i already tried it Panos

There is 5V on pin 47 and pin 48.

I see it drives EXSEL and MPD. I thought I'm handling that case properly, but I can check...

I checked MPD...

If MPD and EXTSEL are used in conjunction that seems to work fine.

If just MPD is used to expose the ram under the OS that does not work. I doubt it uses that, but I should still fix it.

Found an issue with RST_N. I had disconnected it in v10 (I forgot) because when I reset the freezer broke. Well I was just pulling it low for reset, then going high impedance for high. However there is no pull up on it! So I need to drive RST_N high...

I wonder if the IDE2+ needs rst_n.

SO in v10 RST_N was just floating...

IDEPlus info from Simius:
IDE+ detaches OS ROM between $D800 and $DFFF and plug his own memory there. I uses also $D1xx page and $A000...$BFFF area for SDX
IDE+ uses all PBI signals, except: RAS, CAS, RDY, REF, EXTENB and AUDIO
IDE+ latches the address bus (always) about 80ns before rising edge of PHI2 and the data bus (during write cycles) about 80ns before falling edge.

i found this document.. can it be missing voltage on the PBI port?

the interface seems to work on the Eclair, when i press one of its buttons the LEDS respond.. but the menu will not boot

DOES ANYONE HERE HAVE THE BLACK BOX OR THE MIO INTERFACE to test?

Nir

Nir, I do have a 256kB MIO. Two issues. First I don't know if it works, as I don't believe I've ever even turned it on since I bought it. Second, I have no SCSI interface drives to test it with. Most I could hope to do is see if the menu comes up. I am trying to locate a SCSI drive.

can you confirm that you get to the MIO Menu?

After dinner I will find a power supply for the MIO. First I have to confirm it works on real hardware, and then yes, I will let you guys know if it works with CORE11 (or 10).

More info from Simus:
$D800..$DDFF is a ROM, $DE00...$DFFF is a RAM.
MPD is kept low all the time when apropriated bit in PDVREG ($D1FF) is set. EXTSEL is pulled down 40-50ns after one of two conditions occured:

1. MPD is low and address bus is $D800...$DFFF.
2. SDX is on and address bus is $A000...$BFFF

...and released 40-50ns after these conditions are terminated.

Latch signals are generated by HCT123A monostable multivibrator. Pulse width is set at 180ns and is triggered by falling (address) and rising (data) edge of PHI2. With a propagation delays it does ca. 200ns.

Tested and working on Core 13, need other guys to test on MIO and BlackBox
