    IDE to Compact Flash adapter

    There is a lot of table showing this connection but they always assume there is ONE compact flash connected. For most of the pins it is obvious they are in parallel and for /CSEL it is obvious that they should be separated (one will be high and other one low). But they remain 4-5 pins not...

    IDE to Compact Flash adapter

    Hi All, I am in search of a schematic of such an adapter, if possible a schematic of IDE to dual (master +slave) Compact Flash adapter. Thanks. Philippe

    XMODEM question

    Using a logic analyzer I have look on what flow on the serial line. What you say is exactly what I see with the working device (same os and also using TMODEM). On the bad one I can see that Minicom + sx send the first packet but then never receive the ACK from the board. I have continue to try...

    XMODEM question

    Trying to find the problem with strace the difference I found is that after transfer init they come in the log ioctl(3, TIOCMGET, [TIOCM_DTR|TIOCM_RTS|TIOCM_CTS|TIOCM_CAR|TIOCM_DSR]) = 0 in the bad case and ioctl(3, TIOCMGET, [TIOCM_DTR|TIOCM_RTS]) = 0 in the working case. I am at the end...

    XMODEM question

    The main thing I have learn about uvprom (2716, 2732...) is that some cells could be in an intermediate state if the erasing time under uv is to short. The symptom is that, depending about the Vpp voltage (+5V or Gnd) during reading, some bits are one or zero. Of course the Vpp programming high...

    XMODEM question

    The problem is that I loose the console as soon as I ask to Minicom to start a xmodem transfer. So I have no way to run the receive command on 68008 board side.

    XMODEM question

    The first error message I got is Retry 0: Timeout on sector ACK

    XMODEM question

    Hi All, I am facing a strange xmodem problem. On one side I have a vintage 68008 board with a 16C750 which is working well for serial console to Linux Minicom. The 16C750 is interfaced with a MAX232 so I use a serial db9 to usb adapter. The board run SK*DOS 68K with the TMODEM program. I...

    Binary format conversion problem

    Hi Roger, I dont know any programmer that dont do terrific programs... for all others ! Finally I have give a look to the source code of the rom and found some bad documented functions. I can load a pure binary in memory at a specified address and then jump to a start address.This is ok for...

    Binary format conversion problem

    Hi Roger, Thanks for the reply. May be can I get a copy of the source code of your "loader" ?

    Binary format conversion problem

    Hi All, I use a Motorola 68K assembler on Linux that produce binaries in SREC (S2 + S8 records) or STX (Flex) format. On the other hand I have a 68008 board where the monitor can load and run ELF or CPM 68K binaries. So I try to convert SREC to ELF binaries. I have use various combinations...

    AM9511 / AM9512 FPU

    Hi All, Further to test I can now confirm that AM9511 and AM9512 works both asynchronously. They can be interchanged, only end/err to irq/firq connections and of course software need adaptations. Regards. Philippe
