Dear All,
Gus,having given you a head start with a disk drive power supply set
the ball rolling for this letter.
A few issues back I asked Gus how the Elk makes use of a 3.5" drive ,was it
with an 8271 controller as the BBC B uses,or the later 1770 like a Master.
He interested me sufficiently for me to go out and buy one,and so as
regards the old problem of adding a more modern drive I shall attempt to pass
on my experiences so far:
Fortunately,the hardware designers of disk drives though in advance when
designing the new 3.5" drives - they made them pin for pin compatible. All
that you need to do is build a lead:
1.This can be done by cutting the card edge connector off a 5," drive and
crimping on a new 34 way IDC plug.Alternatively,if you wish to use the 5,"
drive again then you can start from scratch,requiring 2x 34 way IDC connectors
and a length of ribbon cable.It should not be longer than 1 metre to prevent
data corruption due to electrical noise.
2.If you wish to use both 5.25" and 3.5" drives at the same time you need
only crimp on a second connector daisy chain fashion somewhere along the
length of existing cable.Then,move the option links on one of the drives so
that both drives don't try and read the disk at the same time.See the chart
enclosed on how to do this - noting that the resistor pack will need to be
unplugged on the drive described as only one pack is allowed per run of cable.
3.If you wish to use both 5.25" and 3.5" drives at the same time but don't
want to risk opening up the drive case then you'll need to carefully cut the
ribbon cable on the two drive select lines (pins 10 and 12) and cross them
over as shown - see diagram enclosed.This will mean that both drives can be
selected (as far as the drive is concerned) as a drive zero and two,but to
software will appear as 0 and 2 then 1 and 3.The cables that run around inside
the case of a PC use this idea of twisting the wires and so a cable from a PC
will do fine (these are available ready assembled from PC suppliers).
4.The next problem is timing.The older 8271 disk controller that most use has
problems accessing some 3.5" drives and will report a drive fault when loading
large files.Try *FX255,207,0 then press BREAK
or *FX255,223,0 then press BREAK
or *FX255,239,0 then press BREAK
These alter the drive step speads etc... and MAY fix the problem.
5.Failing that you'll need to get a 1770 upgrade card (the 1770 is the disk
controller supplied in the Master) which will definately cure the
problem.These cards appear in BBC disk magazine 'for sale' columns
occasionally so you may get lucky.
I hope that has answered and queries you may have had,now if you're after a
cheap brand new SONY 3.5" drive I got mine from CL Computers for `15.95 + VAT
+ P&P you can telephone them on 01274 664110 and they take plastic over the
phone.
Note that mine got bumped in the post and the spring that opens the metal
cover on the disk got knocked out.Fortunately this just clips back in
place.The option link at the back of the SONY drive is for DRIVE0 and DRIVE1
selection,and the minicom plug has the same pin outs as a disk drive power
plug,namely 5v,0v,0v,12v.
