What are the top 10 rarest vintage computer bits you own?

[Ksarul]

My rarest bits are all TI related.

1. TI Dimension 4 prototype (three known to survive, and one of those is just a board set without the case). These later morphed into the TI-99/4.
2. Marinchip S-9900 computer (a TMS9900-based S-100 computer)
3. TI-99/4 p-Code sidecar (only four known to survive)
4. TI-99/2 computer.
5. Both major variants of the TI-99/8.
6. Cassette interface for Tomy Pyuuta Jr.
7. TI CC-40 Video Interface (HexBus peripheral)
8. Centronics Printer Interface for Tomy Pyuuta Mk II.

After that, there are a lot of really HTF items for all of the systems I collect. . .in addition to the common stuff.

Better make that at least five, unless you and I have communicated about this before . Sitting here looking one I picked up on eBay about 10 years ago. It wasn't all that expensive at the time (< $100) and I had no idea they were rare.

Note that I'm speaking of the sidecar version--not the card for the PEB. And if you do have that sidecar type (joy, joy), I am glad another survives. Most of these ended up in schools and were scrapped when the TI computers were end-of-lifed, so their survival rate is significantly lower than that of the Video Controllers (sidecar or PEB versions) which ended up in schools and businesses.

Ack - sorry. My bad. The unit I have is the expansion box cartridge! Didn't realize there was an actual side-car. I do have a speech side-car, but I suspect those are more common.

I’ve got everything you are mentioning. Over 1000 new CPUs/ICs. Vintage and military spec. Even a few prototypes. I inherited everything and I want to find homes.

Who is 'you' in the "..you are mentioning"?

Are you speaking of chips, systems, or both?

He made 4 posts so far and they all start with "I've got". Not sure what to think about this.

"I've got" a spam problem.

Just found this forum so your community is a bit new for me.

Not sure how rare you’d consider, but I have prototypes of Mac IIcx, IIsi, and LC. I have a lot of boxed software, some new sealed, which includes Apple System 5.0, AppleShare Server 1.0, 2.0. I also have the Apple Rhapsody developer release (original) for both x86 and PPC. I have install media for Apple A/UX 2.0 and 2.0.1. Desperately looking for other versions and documentation / full set.
