Memotech 16K RAM pack - broken connector. ZXPand case? £10 plus p&p

Post by Lardo Boffin »

I have a Memotech 16K RAM pack up for sale. As you can see the connector is somewhat broken! £10 plus p&p (UK preferred due to the hassle of selling abroad now).

It may be that this works if you replace the connector but I have no idea.

I suspect it is best used as an original ZXPand case or a replacement case for an existing RAM pack?

I have refurbished the case end screws - overnight soak in WD40 to remove the small amounts of rust followed by a clean in IPA to remove the residue and then sprayed black again. As this is just paint it won’t stand up to repeated unscrewing before it starts to wear off.

Please post on here and PM if interested. Paypal friends and family please.

I believe you can configure these to be used as master / slave RAM packs:

I remember having to set the dips in a certain way to use with the Alphacom printer if it was used behind the memory module and when using the ZXAS software assembler, though what it was escapes me now.

Repairing the connector looks awkward but I'll buy it, can you PM me?

Thx.

The link is broken, BTW.

I found this one :)

Tho it's a 32K :?

It works for me.

Anyway, I've attached a copy.
