Iron - Connection Controller IDE (c) Nemo at the Pentagon.

             Connecting the Controller IDE (c) Nemo.

                                        (C) 2004 Terentyev D.



  The story is, I bought his CD-ROM x8 almost for free (200
rub.) old such filthy fly, and I wanted to muse
chku polushat with good quality (48 kHz, 16 bit, stereo, one
word rulez). Unearthed a scheme controller Nemo, bought detalek,
a couple of times rushed into battle is a fee to breed, then 
the circuit board collect, but the abundance of the conductors 
and the lack of wires MGTF ostanav Lebanese me. The battle 
lasted six months until they bought a collection of pin Roller 
at (c) nedoPC Team (like properly configured) for 300 rus skih 
dollars. Order arrived within two weeks or less above 
(molodtsy!). As it turned out it was necessary to pay in 
advance (I then thought COD), but I made an exception (which is 
a I am exceptional;)) and sent COD.


  The play is the same, act two: it remains to connect the 
controller. For This parcel has been invested in the 
instruction, to me, however, and so would Law is clear. I made 
myself a slot vodvel signals, all but one Nogo - IORGE. Saving 
for this for five minutes lost half an hour while thought: "Oh, 
what would it ..... .... ... ....... ..... why do not pa bot? 
". All have decided zabatsat IORGE ... on the resistor and then 
started, then Claudia does not plow the controller, then all 
the plowing, but somehow not stable. Tired of select resistor 
and tormenting himself and processor, a signal made by the 
normal, and once everything was fine. 


  Here is the scheme:

  Hooking up, everything works. Now copy the files from 
sdromov, UNE Example Disk Virtual TR-DOS, or with other 
software on the Spectrum. Imagine rulez, no need to go 
somewhere, to copy any fi face, unpacked and play, or read a 
newspaper. Slowly the truth, but For example, I was already 
used - it's better than running around with a bunch of msdosov 
skih floppy disks, especially since many ponastavili fucking 
vyndouz XP is a disk so shitty work, sometimes 1.44 Thesis

Key does not read, what 720. Just listen to the music with 
CD-AUDIO, with Conventional audioikov, though prog was not 
under the control of these de Scrap, I wrote his, which 
responds to all of the disk. For example, listening, listening 
... took took a drive, shoved the other, all played on, and so 
on and so forth read separately for this prog Rummy. In the 
application and put all the needed utilities, more comfortable 
working with sdromom. 

  Just trouble-free and hard drive, only now in use
dos scutes. If the HDD to SLAVE, then she did not see and hang. 
A I have the drive and sdrom get along just like this:



                          HDD - slave;

                          CD-ROM-master.


  Or just the hard drive and nothing else. Tortured (well, like
to me that would be visible in isdos sdrom, I'm under it the 
same cd-player written) for a long time, and took corrected the 
ide +3. blk a slave, who have the older version of the driver 
please send us, I did Adjust the same.



  The design of slot: I have set myself a slot without
buffering. In the future we plan to breed a fee of three slots
buffered than anything else. Sam took the connector from DENDY, 
but the beam above to take them to the motherboard PC, ISA8 or 
ISA16 (rather nitride tsatikontaktnuyu part, which is ISA8), so 
their ipolnenie better and safer than DENDY.



  That is, in principle, and the whole saga for connecting the 
controller. Who interesting programming of this device, read 
more articles on this topic in the next issue of the newspaper.
