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.

Eprom Emulator Instructions =========================== If you don't have access to a ROM board with sideways RAM socket(s) but,like me,have access to an Eprom programmer then you could bu ild this little device. It need not only be restricted to storing sideways ROM images,but may be used with other Eprom based devices that need to be continu ally redeveloped - for example it can also be used with Maplin's UM5100 speech programmer replay only board,which accepts Eproms onl y. PARTS... The circuit diagram shows electrically how to assemble the unit,requiring the following parts: 1x 62256 SRAM (28 pin) 1x 28 pin DIL socket 1x SPDT switch 1x Battery box to hold 3xAA batteries 2x IN4001 diodes In addition,it may be useful to have a ZIF socket mounted on the outside of your case,to reduce the stress on,levering the device in and out. BENEFITS... *Switches automatically between battery backup and system powersupply *Can emulate chips 27128/27256 *Low power CMOS static RAM lasts for weeks on a set of batteries *Cheaper than EEPROM (around 22) *Hardware selection of write enable/write protect - gets around protected ROM images BUILD... 1.As the pin outs on a 62256 and 27128 (or 27256) are virtually identical all but print 1,27,28 can be direct one to one connections . 2.Pin 1,27,28 can be bent out of shape carefully with a pair of pliers - being carefully not to stress the metal. 3.Solder a small wire to pin 1 and run this under the chip and plug it into pin 27 of the socket.This becomes address 14. 4.Not CS and Not OE are handled by the Eprom programmer or microprocessor so can be left aline. 5.Having bent pin 27 out of the way of the small wire you just soldered on attach this to the centre pole of the switch.The other tw o terminals of the switch go to pin 14 (GND) and 28 (VCC). 6.Pin 28 also must be split.The two diodes prevent the microprocessor's power supply from trying to recharge the batteries,and vice versa. 7.The battery clip and switch should be wire ended and insulated to prevent shorts in confined spaces and to allow the device to fit under the keyboard on a BBC B. HINTS... *Below around 2.5v the contents of SRAM may become corrupted or lost *I found this very useful to test out the suitability of ROM images before committing them to EPROM *I also fitted a ZIF socket to the ashtray (the punch out section on the left of the B's keyboard where the speech sockets would go) to save having to keep levering the pack in and out *If you do make a ZIF socket,there may be timing problems with piggy back ROMs such as Mega 3.Try connecting a 100nF capacitor from pin 28 to pin 14. *The auto power switching only works if there is a difference of around 0.6v between the main power supply and the battery pack - he nce the use of 4.5v of cells in the battery FROM...
