All, I recently acquired a memopak16 and memopak32 in original packaging for the Sinclair zx81. The 32k may have been used, the 16k was definitely used as you can see the insertion scratches on the edge connector pins. Both are in excellent shape, I have no way of testing these as I do not own a Sinclair. If anyone going to the workshop this coming weekend has any interest I will bring them with me. Otherwise contact me off list if you're interested. Not looking for much, they go for $15-$50 on eBay depending on the day of the week and the barometric pressure ;-) I'm happy with $15 plus shipping for the 16k and $20 plus ship for the 32k. Gets my $$ back for the stuff I picked up they were with which is all I am looking for. Tony Sent from my iPhone
