I have a Casey computer that I bought in the early 90s. It comes with the instruction manual and shoes that were made for me. Size 8 UK.
I haven't used it for at least 20 years and haven't got a clue whether it works or not but I would think that a collector of gambling stuff or museum would be interested.
It worked beautifully when I used it, though I never wore it in a casino in anger.
I'll upload some pix if there's any interest.
PM me should you be interested in making an offer. It cost $2500. I'm based in the UK.
