This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

File contents
The Acorn application note on interfacing to the 1MHz bus recommends that
all output and data lines should be pulled up to +5V and down to ground on
the LAST DEVICE connected to the 1MHz bus. If the Winchester disk unit is
the last device (or the only device) then fit the eight 2K2 resistors and
RP1 to RP4.
If the Winchester is not the last device in the chain then a 1MHz bus in
and 1MHz bus out socket should be provided to allow daisy chaining - this
is most easily done by putting a 34 way IDC socket (one with pins) onto
the cable at the back of the Winchester unit. Note that the Teletext
Adaptor has the special status of last device in the 1MHz bus chain (it
has the terminating resistors fitted).
Fig. 2 to Fig. 4 are the art work for the double sided PCB to build the
host adaptor, as follows:
Fig. 2 - Component placing diagram.
Fig. 3 - Bottom side - track layout
Fig. 4 - Component side - track layout
On Fig. 2 the crosses "+" indicate the 0.8mm holes used for the IDC
connectors and through pins. Our PCBs are not through plated boards,
instead through pins are used to connect the top layer to the bottom, a
pin is used in every position that is not an IDC connector.
You may have difficulty making PCBs from this artwork as photocopiers have
a tendency to slightly change the size of the artwork and add distortion,
as an alternative you could wire wrap a board, or even build the circuit
on Veroboard...

Controller configuration
For the DTC510A/B controllers there is an ten byte parameter block stored
in the controller software EPROM on the controller card. ADFS expects the
power up default drive parameters to be correct or the controller to get
the parameters from the drive (eg. Adaptec/Xebec).
The following table indicates the bytes that have to be altered and their
addresses within the EPROM. NOTE: the addresses are for firmware version
WD24 (DTC-510A controller) and WD30 (DTC-510B) if you have a different
firmware version number the parameter block may be at a different address.

05A3 0949 Do not change 0A 0A 0A 0A
05A4 094A Do not change 00 00 00 00
Ampex drives are identical to the Rodime drives (they are made under
licence). Rodime E series appear to have less heads but more cylinders.
NOTE:
1. Max head address is number of heads - 1
2. Max cylinder address is number of tracks -1 (16 bit number)
3. Rodime drives are operated in fast seek mode, buffered with ramped
stepper speed controlled by the on board processor on the drive
(see Rodime manual).
The format of the ten bytes is the same as detailed in the DTC manual for
the "load drive parameters" opcode except that the 16 bit numbers are
stored low byte first. For other drives you will have to calculate the
parameters and blow an EPROM with the appropriate bytes. If you don't
have the facility to edit/blow EPROMs then I can probably do it for you.
Controller links (DTC-510A)
Link W1 on the controller should be open to select 256 byte sectors then
the default parameter (closed is 512 byte sectors), and link W2 should be
across BC. Link W (by the crystal) should be on.
Controller links (DTC-510B)
Sect Select links W6 and W7 should both be open to select 256 byte sector
operation. W1, W2, W3 & W5 should be open, parity select W8 should be
open, and W4 should be connected between 1 & 2. Link ID0 should be
connected (nearest to W7).
Getting going
Once a host adaptor has been built or purchased, and the controller card
has been configured for the Winchester the system can be put together,
formatted and tested.
Power up the Winchester drive, controller, host adaptor and BBC micro at
the same time, ADFS should be installed as the highest filing system ROM
(preferably the highest priority ROM, socket 14 is okay is you have BASIC
in 15) a high priority socket is needed as ADFS has to service interrupts
from the host adaptor, and is reasonably timing dependant, a few ROMs can
cause problems if they are in a higher priority socket (eg. IEEE filing
system).
If you have a Master you should do a *CONFIGURE FILE 8 to make ADFS the
default filing system. *CONFIGURE HARD to select Winchester by default
The system should be hanging after the "BBC Computer 32K", "Acorn ADFS"
messages waiting for the Winchester to spin up to speed (takes up to 30
seconds) and become "ready". After this time ADFS will try to "mount" the
drive, that is, read in the free space map and root directory. The DTC
controllers have 8 status leds, they should be displaying 01000000, which
is the idle condition, if they are 11111111 (all on) then you probably
connected one of the cables the wrong way round or forgot the power on the
host adaptor.
If you get "Disk error 5 at :0/000000" then hit BREAK, the system should
now hang and wait for the drive, this seems to happen with some RODIME
drives on the DTC controller.
Depending what is already on the disk (garbage as far as we are concerned
on the first occasion), you will get a "Disk error", "Bad FS Map",
"Compaction required" or "Broken directory" message and the system will
then probably hang or drop into BASIC.
Press Control F and BREAK, ADFS will be entered without looking for the
free space map/root directory. Load the Winchester formatter program from
floppy disk (remember that under ADFS your floppy drives are now :4 and
:5), example LOAD ":4.SYSROOT.WINCHESTER.DTCFORM"
Run the format program, it should take about 1 or 2 minutes to format the
drive, depending on capacity. After the format is complete the drive
should be exercised by the diagnostic routine, when finished successfully
you can initialise the drive.
