Sideways ROM type software.
AND EPROM PROGRAMMER
(Erasable Programmable Read Only Memory) is the type of ICs that you install
into your Sideways ROM sockets. Its appearance is quite easy to recognise: it
has a glass window. The EPROMs are normally blank when you buy them from an
electronic computer distributor (such as Watford Electronics, Technomatic or
Semicomponents, to cite a few). The BBC computer can only read the EPROMs if
they are inserted into the Sideways ROM sockets but cannot write into them as
into Sideways RAM. To do so you will need a special hardware device capable of
the correct programming voltage (21-22V);
2) the correct programming pulse (50ms per byte);

are the steps to program (or ‘blow’) an EPROM:
connect the Eprom Programmer to the user port;
place a blank Eprom in the programming socket;
enter *BLOW <filename> <RETURN>

off the computer and turn it over to expose the row of sockets under the
the 20-pin IDC cable to the user port, situated between the printer port and the
1MHz port. Make sure that the ‘bump’ on the IDC it mating correctly

are two LEDs (Electra-Luminescent Diodes), coloured red, on the EPROM
PROGRAMMER. The one nearest to the ribbon cable is labelled ‘5’ (for
5 volts)—the ‘Vcc’ indicator; the other one is labelled
‘21’ (for 21 volts)—the ‘Vpp’ indicator. Vcc is
also the ~v. supply to the Eprom Programmer, borrowed from the user port. Vpp is
the programming voltage supply generated by a switched mode power supply built
into the programmer.
NO INSERTION OR REMOVAL IS ALLOWED WHEN EITHER LED IS ON! Permanent damage (pure
loss) will result from careless handling of Eprom devices.

you are sure to understand how they work:
the switch is on, the LED will be lit; if the switch is off, the LED will go
off. Try them as many times as necessary.

frequency going through the coil. The Vcc switch does not produce any

Eprom Programmer users, so please pay attention to this device—simple but
capable of costing you money unnecessarily.

1 (top left-hand corner) of the EPROM is facing the ‘1’ sticker on
the Eprom programmer. If in doubt ring us for advice. The top of the EPROM has a
small notch. It should match the same notch on the programming socket. The
bottom of the Eprom is facing the ribbon cable.

the Eprom programmer cannot distinguish between a 2764 and a 27128 EPROM,
although it can program both devices, it cannot take a decision; it asks you to
take it. Basically the answer is very simple: if the file length is &2ooo or
less you can put it on to either a 2764-35 or 27128-35 EPROM. If it is greater
than &2000 but smaller or equal to &4000, a 27128-35 will be

whereas their true length is only 2000 Hex or less. Please correct this by
