That is wrong Tarquin.
The QL internal ROM space has always been 48k. The original couldn't
fit in that, so they fitted the overflow in an external ROM (dongle)
plugged into the ROM slot. This was a very nice ROM board made by
Sinclair that in fact had space for two eproms.
I use one of these (with one chip) to test QLs.
Very soon they added the extra 16k internally with piggy backed chips,
but that disabled the ROM slot.
Interestingly the pcb has always catered for a mix of internal rom size
/rom slot. There are jumper slots on the issue 5 pcb - the std has
three resistor like components (one black bar === 0 ohms).
All these QLs had to be returned to Sinclair when the ROM fitted in 48k.
I returned my original QL, but Parcel Farce (then part of Royal Mail)
lost it.
