If additional EPROMs are required or a older monitor is being upgraded than the

procedure below must be followed to program an EPROM.

a) Obtain a 27512, 200ns EPROM. Note that the EPROM may be any of the

27512, 27C512 family of EPROMs.

b) The binary file that is to be burnt into the EPROM should be obtained from

Signal Engineering Services. Must be version R3.7 or later. The file name will

be LXR37.bin where 37 is the release number for version R3.7.

c) Connect the JED PC EPROM programmer to the PC's parallel port and make

sure that power is connected to the prom programmer.

d) Invoke the prom programmer software by the DOS command "pp".

The default eprom type should be 27512 (on RHS). If it is set to anything else then you

will have to go to the option menu and select the eprom type 27512.

Select the option 'Program EPROM from diskfile' (this is the first menu item)

The program will come back with:

COMMAND

Enter filename:

type in 'lxr37.bin' and hit return

The program will come back with:

Enter offset <diskfile> [0] : (hit return)

Use standard Algorithm ? [Y/n] : (hit return)

Programming will begin by doing a blank check of the EPROM, the EPROM will be

programmed with the file named name.bin, then the EPROM will have it's contents

verified. The whole procedure takes just over 4 minutes on a 386SX computer. Do not

disturb the EPROM until the whole process is complete.

a) A label must be affixed to the window of the EPROM when it has been

programmed. This label must have written on it the date and the software

version number. The software version should be R3.7 or later. Suitable labels

can be obtained from most newsagents.

b) Replace the EPROM or fit the new EPROM as per the instructions in Section 4.
