I have to sell a complete British BBQL system in a perfect state and rarely used.

Including original packaging, leads, PSU and english manual (as new).

The motherboard is a D14/Issue 6 layout, fitted with a JM ROM.
Keyboard membrane was renewed as well as all main ICs (68008, zx8301, zx8302, 8049).

Also fitted with a rare internal 640KB of RAM memory leaving free the main QL expansion port.

Price 300 €uros (+ shipping from PARIS region).
If interested or any question, please send a PM via the forum.
Alain

Hello Alain,
Out of interest, are you able to show pics of the internal RAM upgrade? Was it something purchased or a home made upgrade? It is in very nice condition.

HI Chris,
It is an internal memory upgrade kit called ql640 I purchassed in 1988 for 101 pounds from Sector software (don't know real maker) and used for a while on my first ql until I skipped to SGC...
The kit includes socket, ship and capacitor and needs some IC remove, pins bend, replace. Not too complicated but has to be done carefully. It worked very fine for me. Internal ram extension is automatically disabled if an external ram is here.
Here are pictures of the 3 pages manual I carefully kept but I am not going to open the ql if still out of interest ;)

Hmm, is it a fast or slow external memory?

See last page of the manual Alain has provided.

Internal RAM expansions are slower than external expansion, the Trump Card did speed the ram access slightly,.
