EPROM dumps (etc)
Please note that these EPROM dumps are provided so that if something happens to your EPROMs (broken legs, blown from being inserted the wrong way around, etc) then you can create your own replacement.
Please note that these dumps may still be somebody's property, so please use them responsibly - to keep old hardware going.
The dumps have '.dat' extensions. They are binary data, so don't try to get your browser to display them, it will look really weird, like the picture on the right here...
On most RISC OS browsers, click on the link while holding down the Shift key to save the file.
On most PC browsers, right-click the link and choose the option Save target as... (or something similar).
Please do not email me to ask what you should do with these dumps. If you don't know, you don't need them!
To those small few that were audacious enough to ask if I had any later versions... don't you think if I did, they'd be here?

SERVERS
- Acorn FileStore E01S / Stacking FileStore / FileStore II
FileStore EPROM: v1.33, in two 32K halves. © 1988 Acorn Computers.
The FileStore uses a single 64K EPROM, so you should blow the images in in 32K chunks as
directed. The lower 32K is the server code and the upper 32K is the MOS code.

FileStore EPROM: v1.40.00, in two 32K halves. © 1989 Acorn Computers.
The FileStore uses a single 64K EPROM, so you should blow the images in in 32K chunks as
directed. The lower 32K is the server code and the upper 32K is the MOS code.
I tracked down these EPROM image files. They provide file server version 1.40.00,
dated 1989.
I do not know if they are E01S only, or if they will work in both.
Read more about upgrading to this firmware.

- Level 2 File Server
Not strictly an EPROM dump, but it seemed a logical place to offer this file...
This is the first mainstream file server released by Acorn, product code
14-AES21-0002164. It requires either a BBC B or a Master, with a 6502 2nd processor
(in both cases) and a 2×800K floppy drive.
Also included is a disc formatter, a password file editor, and JGH's Y2K patch.
This is the Level 2 server version 1.02. © Acorn (no date).
- Level 3 File Server
Not strictly an EPROM dump, but it seemed a logical place to offer this file...
This is an enhancement of the Level 2 server, primarily to cater for use with 'Winchester'
discs (either 10Mb or 30Mb?). In terms of serving, it is quite similar to the
FileStore from a user's point of view. It requires a BBC B or Master with
co-processor, a Winchester drive, and an 800K floppy drive (to boot from).
Also included is a disc formatter, a disc initialiser, verifier, backup tools, and JGH's
Y2K patch.
This is the Level 3 server version 0.92. © 1984 Acorn.
- Acorn FileStore E01 / FileStore I
FileStore EPROM: v1.31, in four 16K parts. © 1988 Acorn Computers.
Note, this is for the original FileStore, not the E01S 'stacking' version.
I do not know how many EPROMs the E01 actually has. I would imagine that the
ROM dumps are blown in the order given, with either the server and the MOS in
separate 32K images, or the server in the lower 32K and the MOS in the upper
32K of a 64K EPROM (like the E01S).
- SJ Research MDFS file server
MDFS boot EPROM: v1.05. © SJ Research (no date).
MDFS Master disc image, plus FS code: v2.00. © SJ Research (October 1992).
Note - this is an 800K disc image, I suspect MDFS format. As to how to install
it, you're on your own...
- SoftMDFS
Not strictly an EPROM dump, but it seemed a logical place to offer this
file...
J.G.Harston has taken Alan William's awServer and
extended it so it behaves like an MDFS. No longer do you need a
huge metal beast on your desk,
an old A3000 with built-in harddisc will suffice as a software MDFS.
This is !SoftMDFS version 0.01. © 2000 J.G.Harston.
BRIDGES
- SJ Research Bridge
SJ Bridge EPROM: v3.04. © 1992 SJ Research (1992/07/06).
- Acorn Bridge
This ROM is apparently for the Acorn Bridge. I cannot say which version (or
date) this is as there is no such information in the dump. Actually, there is
quite a lot of blank space in the ROM dump - in an 8K EPROM, only 2.54K is
used!
It is interesting that the command string to detect the presence of the bridge
is the text "Bridge", however this does not appear anywhere in the
firmware...

PRINTER SERVERS
- Printer Server ROM v1.00
This is the original Printer Server ROM.
Strings in the file are PSERV, BANNER, PRE,
POST, ENDTEXT, NOBANNER and
IGNORE.
It is Printer Server version 1.00. © Acorn 1982.
- Printer Server ROM v1.11
This is a much improved Printer Server, with some help and claiming support for the
following printers: Default, Ollivetti ink jet, Epson MX80/FX80, Walters Microsystems
2000, Mannesmann Tally MT180, Mannesmann Tally MT140, Micro Peripherals MPI99G, Florida
Data BNY (by the way, it isn't my typo, it says 'Ollivetti' in the ROM).
Interestingly there is a message in the ROM which reads: The authors of ANFS are;
B Cockburn J Dunn B Robertson J Wills.
The code appears to be duplicated in the ROM, so I am not sure if this is intentional or
if it is really an 8K ROM.
It is Printer Server version 1.11. © Acorn 1982.
WORKSTATION UTILITIES
- ☕ NFS...
The Network Filing System (NFS) is a simple 8K EPROM which contains all
the code necessary for your Beeb's operation as a "discless workstation". It is
capable of booting from, and running software from, some sort of file server running
on the Econet.
NFS also forms a part of DNFS, where essentially the two parts are included
within the same EPROM.
NFS can also be used in conjuction with other disc filing systems (DFS, Watford's
DDFS, ADFS, etc...), though in this configuration you will be using two of
the available ROM slots.
- NFS 3.34
This is NFS (Network Filing System) for the BBC microcomputer, when
operating as a discless workstation, or alongside a DFS of some sort.
This is NFS version 3.34. © ROFF (no date).
☕ Early crappy NFS. In addition to all the 3.35K
"issues", you can add to the list that it doesn't support hidden entry so
you have to log in with the world able to look at your password. Not
recommended!
- NFS 3.35K
This is NFS (Network Filing System) for the BBC microcomputer, when
operating as a discless workstation, or alongside a DFS of some sort.
This is NFS version 3.35K. © ROFF (no date).
☕ This is a typical standalone NFS. While it permits
the use of ':' in the *I Am to allow
passwords to be hidden, it would appear that privileged stations (any with
station number 240 or higher) can override the built-in protection levels and mess
with the station, peek and poke memory and all the other immediate operations. The
printer code isn't capable of sending null bytes, so graphics printing is not
possible. If you want to make use of the tube interface code, there are numerous
bugs there too!
- NFS 3.60 (standalone)
This is NFS (Network Filing System) for the BBC microcomputer, when
operating as a discless workstation.
This is NFS version 3.60. © ROFF (no date).
☕ This is the most recent common version for the BBC
micro. It is usually included in other products (such as DNFS), and because
of this you will not easily find it available elsewhere.
This is an ancient EPROM dump from a school Beeb (I can't believe I kept it all
those years!). The only other source of NFS 3.60 standalone is MDFS.net and
at a casual look they seem the same. I have neither time nor inclination to diff
them. This might seem odd, but there is controversy over the origin of NFS 3.60 as
to if it is authentic or a rip from a DNFS ROM. Both may turn out to be true? Who
knows...
This version has been either set or modified so that both the fileserver and the
print server are station 0.254. This is consistent with my old school using a
FileStore server.
☕ NFS 3.60 offers all the expected Beeb networking
capabilities. If you need to pick a standalone NFS to run, this version is
recommended; though you may prefer the advanced functionality of ANFS
(see below).
- ☕ DNFS...
The Disc and Network Filing System (DNFS) is a combined 16K EPROM which
combines the functionality of the 8271 compatible DFS and NFS. While it is expected
that two filing systems may have some generic code in common, this does not appear
to have been exploited in the DNFS, as the EPROM contents are essentially DFS and
NFS side by side.
At any rate, this EPROM may be used to provide both 5¼" disc and Econet
network functionality in a single slot... if you are happy with the various
limitations of the 8271FDC, which arguably was an obsolete part even before the
BBC Micro saw the light of day! (if you think that's bad, you should eyeball the
part in the FileStore - congrats for making a working double density 3½
interface out of it, but... did Acorn secure a job lot of obsoleted stock, or
something? why not the 1770 like in the Master?)
- DNFS 1.20/3.60
This is DNFS (Disc and Network Filing System) for the BBC microcomputer.
It requires an 8271 disc controller (not a 1770).
Contained within this dump is NFS version 3.60 and DFS
version 1.20. © ROFF (no date).
☕ Defaults: FileServer = 0.254, PrintServer = 0.235
- DNFS 1.20/3.60 (modified)
Exactly as above, but modified to default to the file server and print
server both being station 0.254, useful for those with a FileStore that
provides both functions at the same 'station'.
☕ The modification was performed by comparing
the NFS 3.60 part of this EPROM image with the modified 3.60 EPROM image
above; and seeing were '254' (&FE) and '235' (&EB) showed up.
- ☕ DFS..?
The Disc Filing System (DFS) provides no network functionality
whatsoever.
What it does do is it provides support for the later 1770 disc controller. I am
not aware of any 1770'd version of DNFS; but since this is a 16K EPROM, there
probably is no such thing. So use this alongside an NFS, yes, two slots...
This dump is provided as a convenience to people with a 1770 controller. There
are numerous other options - DFSs from third parties, DDFS, etc...
- DFS 2.26 (1770 compatible)
This is 1770 DFS version 2.26. © 1985 Acorn.
This version of DFS includes SRAM utilities, for those who have expansion
boards, or who have modified their BBC micros to support SRAM and multiple
EPROM images within the existing ROM configuration (its actually quite
easy, here,
read this!
Also included are commands to format and verify discs - notoriously missing
from the earlier DFS (thus needing some sort of "utilities" disc).
- ☕ ANFS...
The Advanced Network Filing System (ANFS) acronym might have led you
to hope for a network version of ADFS. Sorry. Nope.
This is a reworked version of the network filesystem that includes local
file buffering and a number of common commands for which you previously would
have needed separate utility programs, such as *Lex,
*Prot, *Access,
*Pass, *Wipe
(etc).
Version 4.18 is for the BBC Micro, but it comes with a caveat that the
value of PAGE will rise by &500 (1280 bytes), which may be a lot on a
32K machine, especially if you have a disc filing system installed too.
Things are better on the BBC Master, there's memory to spare and the ANFS uses
"Hazel" (&C000-&DFFF, filesystem workspace).
- ANFS 4.18 (BBC B / B+)
This is ANFS (Advanced Network Filing System) for the BBC model B.
Contained within this dump is ANFS version 4.18. © 1985
Acorn.
☕ This is the last known version for the BBC micro.
- ANFS 4.25 (BBC Master)
This is ANFS (Advanced Network Filing System) for the BBC Master.
Contained within this dump is ANFS version 4.25. © 1986
Acorn.
☕ This is the usual and last known version for the Master.
- Network Expansion ROM
This is the Network Expansion ROM, which apparently provides a bunch of
new commands for network stations (BBC micro, maybe Master 128?).
This is Network Expansion version 1.20. © 1986 Mike
and released into the public domain.
☕ The commands with help provided are:
CONT <st.list>
FATAL <st.list>
HALT <st.list>
PEEK <stn>;<dst.ad>;<len>;<src.ad>
POKE <st.list>;<src.ad>;<len>;<dst.ad>
PROTECT <P> <J> <U> <O> <H>
ROFF
SEND <st.list>;<text>
SENDPROG <st.list>;(<page>)
SYS
VIEW <st.list>
VIEWF <st.list>
WHERE <stn>
The following may also be commands, no embedded help is provided for these:
CLIST
ERROR
MOTAN
STATION
- TCP/IP for the BBC micro
Yes, seriously! TCP/IP over Econet for the Beeb, and it includes a built-in
telnet client. Supplied as a ROM image plus complete sources, we should bow
before Philip Blundell while muttering "we're not worthy"...

MISCELLANEOUS DOCUMENTATION
- 6854 ADLC datasheet
If you download the 6854 datasheet that is doing the rounds of the various BBC micro
support sites, you'll probably have noticed (if you use a PC) that Acrobat Reader
will frequently fault with this message:
As Acrobat Reader (certainly v5.1.0) is a bit crap, it won't try to display what it has
been able to extract from the document file. Oh no, it'll toss it and leave you with a
blank page, which really isn't terribly useful!
I used Ghostscript to recreate the damaged PDF. It is around 55K larger, but it
works with Acrobat Reader...
☕ If you want another whinge... I cannot upgrade my copy of
Acrobat Reader to fix supposed security flaws. Why? Because I deleted the Acrobat Air
or whatever it was called, along with the Installer files. Why? I have a small 4Gb
XP partition and with all these service packs and stuff it is getting kinda full. So I
don't see the point in wasting disc space to a function I don't use and a set of files
that I could just as easily download if I needed them again. What the hell sort of
installer refuses to work if the previous installer files aren't there? It was, like,
20Mb, isn't that enough? There is a way, I found it online for the last update I
had to frig manually, but - sorry - I consider PDF to be a document format. All
this speak of JavaScript and other script and online this-and-that frightens me. Maybe
if it wasn't for all of that bloat, the PDF reader would be small and snappy and not
need "important" security patches?
Speak of which, just as I write this a message has popped up to tell me that Adobe Reader
9.2.0 is available and how important it is that I update promptly... Yeah.
- 14411 Bit Rate Generator datasheet
If anybody is using the original Acorn clock box, I have scanned my datasheet...
☕ Gee, couldn't you like totally fake this with a timing
crystal and two 4 bit counter logic gates? ☺ After all, 1MHz/8/4 is about 31kHz...
Can you help?
- Can you help?
I am looking for other network related stuff...
- Was anything produced for the Electron?
- SJ FDFS and HDFS BIOS ROMs.
- Later versions of stuff given above?
- Sources to any of this?
- Anything else Econet related!
