Re: Sandy RAM card, PAL blew up.
Unfortunately, this is a bit out of warranty. :D The card is simply a thru-con RAM card with the DIN connectors not fitted. I didn't assemble/test that specific SQB board as mine only had pins fitted where signals were used. Sorry, I don't have the PAL equations. I wish I did - they would solve a lo...

Re: Ethernet for the QL
I think you finely demonstrated my point.
Anyhow, I look for ward to more alternatives to the really outdated CP2200 chip. Alternatives that reduce the burden on programmers and users but most of all on the system.

Re: Ethernet for the QL
And that’s why there are three solutions for the QL. Some people want the stack run for them and a driver. Some people want a TCP stack hidden behind a Hayes interface. Others want a manually operated, TCP stack in the QL, hardware to wiggle the bits and do everything manually. I think only one of t...

Re: New Q68 Case
The sockets were so cheap and tarnished Sinclair was probably paid to use them.
Almost as bad as the CPU socket.

Re: New Q68 Case
If you just use plain sockets and put the resistor in a jack, it works. Much cheaper than sourcing the switched jacks. This was in answer to Derek’s add-on, not the original design. Not that the termination was ever any good anyway.

Re: New Q68 Case
A 3.5mm jack with a termination resistor solves this quite neatly.

Re: using floppy drives with gold card
All future designs of floppy interfaces for the QL should have a bit flip jumper that just puts the drive select line through an inverter.

Problem solved.

Re: Any ideas what this unknown expansion card is?
I don't know who made this card, but we did have a couple in a parts bin at Sandy back in the day. Arnie used one for quickly looking at ROMs.

Re: Gold card weird action
And upgrade those AH ROMs! Not fit for use!
