This – hopefully – is a 16K RAM pack, as it arrived at me without any RAM. I will fit a 16K RAM someday and test it…
It also contains a socket for some kind of beeper which was hoped to bee purchased by the customer later.
Most interesting was the "X-ROMCARD" upgrade offered for approx. £16.00. I believe this was just the Eprom for which there was a spare socket, which was occupied in my RAM pack. :-) It contained machine code routines for games, some kind of machine monitor and an Eprommer. The Eprom socket was a simple cheap socket and obviously one had to supply the 25V programming voltage on one's own. The Eprom contents is archived in a .rom file below. I hope this was really the "X-ROMCARD".
