Hi
A quick Q.

Are there any new QL memory expansion and /or disc interface cards for the BBQL currently available to purchase ?

Or is now just second user stuff that people can buy ?

As far as I know the only combined disk/RAM was the Trump card clone from Siberia, but he can no longer send those, for obvious reasons, so 2nd hand is the only way.

As far as I know, not even single memory expansions or disk interfaces are available new anymore.
Not very long ago there still was an internal memory expansion, but it seems sold out.

I occasionally make up and sell 512k internal RAM upgrades (that fit on top of the CPU and can be disabled by a tiny switch at the side).

I have a couple available at the moment, but don't have them on eBay right now.

Hi,

Maybe an existing disk interfaces could be reverse engineered, what would be the interface required, bearing in mid the Super/Gold Card suffer from custom chips that maybe unavailable.

There are circuit diagrams of a few of the older interfaces on my site (SuperQBoard and Medic IIRC). Maye something could be developed from these, although it might be better to develop something new with available chipsets if that were possible. Seems to be a continuing demand for these interfaces. Tetroid was well placed to take advantage of the demand before the sad situation in eastern Europe.

Shipping - no problem ( except Poland and Finland in Europe, South America, Australia, New Zealand ).
Payment - problem, only via non russian PayPal accounts ( my friends ) or exchange for other parts.

I have had this year an EXCELLENT experience ordering from tetroid. I got my TDI2 interface (ram, floppy, and ql-sd) and Super Gold Card delivered to Spain in a few days after payment.

I strongly recommend buying from him.
