I managed to find one locally with 23mm. However I have two other boards where I simply bend the pins a little on the Jameco part. The pins themselves are fairly long. You can bend then 90 degrees, then 90 degrees again to get the 23mm spacing.

Hi John / Andrew
Please can you advise on the part number and source for the coin cell battery holder as I have searched several UK suppliers (Digikey/Farnell/Rapid) for CR2032 coin cell holders but datasheets all show the pin spacing at 20.0mm whereas the holes on the RAM&ROM board are 23.0mm apart.
There is one that looks similar on the Jameco website (in the US) but there is no datasheet to confirm specs
