Yes, they are....

So, for the seller this will bring the money for the summer holidays... but no more for the higest bidder ;)

In over 6 years, I have never seen one on ebay. I know two people that have something to program these. One guy lives in Seattle and has some sort of home brew. Another guy lives in Spain, I believe. Not sure what kind he has.

It was a pretty good package.

Mike;
Your affinity for the 71 is well known; you tried to explain it to me once but since i can't find the enter key on the dam thing.... Your "spares" box is justly famous too. Are you planning to come out with a line of quasi clonix-71 modules?

I recently decided what I thought would be the ultimate HP-71 peripheral along those lines. That would be a RAM box that carried images of every known HP-71 ROM, and let you map them anywhere available in the 512K address space. It would also let you fill the balance with system RAM. You would thus need about 512K + (cumulative size of all ROM images, compressed) bytes of RAM in the thing. I don't know if it's possible without cutting traces, but it should sit in a front port, leaving the card reader slot for .. wait for it .. a card reader! USB connectivity would be cool, too.

However, if Mike were to simply offer to burn arbitrary images into his now bountiful stock of CMT 32K EPROM modules, I'm sure he'd find a ready market. I know I'd buy a couple. 8)

Not exactly correct as I think. About 18 month ago there are an equal systen, together with a HP-71B and about 10 EPROMS sold on ebay.. final price was about $1150.. (Or was this another HP-71B EPROM burner?)
