Hello!

I have been collecting (HP-) calculator stuff since decades and still watch the offers and prices because unfortunately no collection is ever complete. But don't take my words for the truth, I am missing a lot of good offers and especially the super expensive ones.

So I would say that if you want a quick sale with the minimum hassle, offer the whole lot here in the classifieds or on eBay for something like 300 $/Euro/GBP. The way the accessories are mounted inside the briefcase is quite smart and someone might find it useful the way it is. Some might even consider it a shame to rip it apart. Unless the foam rubber lining has turned sticky or brittle over the years as I have seen quite often. In that case it is probably best to take the lot apart.

If you aim for the most money, list the items individually and have patience. Many collectors probably already own most of these accessories (I for example would only care for the wand/barcode reader) and may be tempted to pay premium if it helps them to fill a gap in their collection.
My estimates would be: 50-100 for the printer, 100 for the tape drive (double or triple that if you can provide blank tapes with it - the drive is almost worthless without them), 200 for the wand, 50 each (maximum!) for the modules and their relative overlays and instruction sheets, 30 for the bag with cables. But I know little about these modules, there might be a hidden gem among them.

Max

NB: Many US sellers, here and on platforms like eBay as well, limit their offers to the "lower 48 states" or similar. Although the United States are certiainly the largest single market for these items, selling internationally will increase the number of potential buyers tenfold. It is really not difficult to sell internationally. One little form to fill in, all the associated extra cost will be charged to the buyer.
I agree with Max's wise words. In the end, the value is what the second highest bidder is willing to pay.

If (as you said) you know nothing about these items, you'd be better off having someone sell them that is an expert. Especially since there is no calculator included (and the most interesting items that would have been in this lot appear to be still inside the missing calculator- namely the PPC ROM).

Good luck!
Not much to add other than you have two modules which do not have anything written on them. So one or both _could_ be more valuable, though none looks like a HEPAX afaict.

Might be worth to take them out and see if they have anything written on them and/or put them in a working 41 and do a CAT 2.

Those two look like port covers to me (the 'handle' looks different, since it isn't separate) but I would love to be wrong about that...

Those are port covers. He says "6 ROMs" in the description, would be 8 if they were modules
OK, thanks for your feedback and assistance. I guess it’s not worth bothering with. I’ll just toss it out.

Good way to get people's attention!! Smile

Are you planning to sell it here in the Forum or elsewhere?

Do you know if the items work?

A likely reason for low response is after some initial replies, there was no feedback, so most folks likely assumed you moved on and sold it all elsewhere, which is common for new users who join simply to sell (or price) stuff.

Are you willing to ship to US buyers not in your area? To other countries? (As Max notes, it's actually fairly simple to do so).

With a bit more information, you'll likely get more response, but a lot of folks don't want to spend a lot of time supplying detailed replies so someone can go sell stuff elsewhere without an opportunity to actually participate (make offers to buy, etc.).

Hope this helps to clarify what is/isn't happening.

I hope you are doing well!! Well said, sir! I find it both interesting and sad how many people come for a pricing here, with no intent to sell in the classifieds forum.

Love it or hate it, ebay is a far better pricing system than asking our opinions in the forum. It isn't a perfectly efficient system, but that method does allow potential buyers to take into account all the things you have wisely asked: working, damaged, incomplete, rare /common, shipping costs, returns or not, tested or not, bundled or parted out, sold by an expert or a novice etc ...

I think the general answer most pricing folks are seeking is "Is this worth my time?", which is very close to the question being asked by the OP here: "Given that I didn't take any time to research these common items myself, is it still worth my time?". Both are unanswerable without much more discussion about how much a person's time is worth.

For the OP: If you are willing to toss $400 of your friends stuff because a group of strangers didn't reply to your vaguely worded non-advertisement, you're either rich and wasting your time here or you're a terrible friend, or both. No offense.
