What are your "Holy Grails?"

This actually got me thinking. Not so rare, har har.
I think were I to get everything I want - but don't yet have - would include the following:

1) TRS-80 Model 4 with both floppies.
2) A PC-compatible (non-Tandy) 80186 motherboard. (Saw one back when they were new, but never since.) Probably 10 or 12MHz.
3) Commodore B-128 with drives and peripherals. But I ain't paying $600 for one. lol

That's about all, really. As I tinker with other different ones, that "unattainable" list may expand, but that's all I'm truly after at the moment.

The only other 80186 Systems besides the Tandy 2000 that I know of were the TI Professional (there is one on eBay now) and th Mindset. Are there generic motherboards with the chip?

The Burroughs ICON also used a 80186. That's another of my Holy Grails. Most of them were deliberately destroyed though so I don't think I'll ever find one.

There were several other MS-DOS systems using the 80186. The problem is that it's difficult to make an 80186/88-based system that's completely hardware-compatible with the traditional IBM PC. Some might even say that it's impossible. Which is a shame, because the 80186 is a very simple-to-interface chip. Mostly, it found application as an embedded controller (e.g. USR Courier modems, Cipher tape drives, laser printers, etc.).

The NEC V40 faced a similar situation, although it was far closer to the standard PC architecture.
 
Heathkit H-8 with the H-19 Terminal and dual floppy drive's. Tandy 1200HD a rebranded Tandon. And also a Tandy TRS-80 2000 with HD and CM-1 color monitor. Oh and all in working condition.

Yup. They came in proprietary cases, but the board layout was the same as a standard AT -and only had 6 slots instead of 8. Put out by a company called Swan Technologies, if I remember right.

I have a PCI SCSI host adapter that uses an 80186-25. Even if it's just a peripheral card, that alone makes it unique.

That's not to say I'm not open to other makers of boards. I just want one at 10 or 12MHz speed. Not too terribly concerned about 100% compatibility really. So long as it fits in a normal case. Or comes with the one its meant for.

I know, it is unfortunate that Intel released the 186 and the 286 at the time it did.
 
I have a 20th Anniversary Mac Prototype if that's not too new.

If we need older I have a Compaq Portable I, which isn't all that special as they aren't insanely rare nor insanely common.

Scratch that, I read the topic wrong and posted what I already own.


I would love to own a NeXT system, just to own one. Another system that I wouldn't mind owning is one of the odd Compaq SystemPros that allowed for asymmetric multiprocessing.

I would really love one of those SPARC-based laptops. They seem to be less common than Altair 8800s here, I assume because they probably cost a ****ton of money new.

I've been offered an ALR 6x6 system at one point which was six pentium PRO chips but it just consumed a crazy amount of power. I was better off playing the Quake series on an Onyx.
 
Money and space, I can usually get more of. It's TIME that I don't have enough of.

If I had unlimited TIME, I would love a nearly-complete Apple IIgs setup. Which is a decision fuel purely by nostalgia and nothing else. (I never owned one, but I coveted them.)

Most of the "must-haves" have taken me up to 25 years to collect, but I finally have just about everything I've been looking for: AT&T PC 6300 memory board, IBM Music Feature Card, Roland SCC-1, IBM PS/2 Model 25, and finally, a functional 5161 expansion unit which is now in monthly use.
 
After collecting for a decade you pretty much have what you really wanted (that is affordable) and you are left with stuff you wouldn't mind having or trying out.
 
1) TRS-80 Model 4 with both floppies.
2) A PC-compatible (non-Tandy) 80186 motherboard. (Saw one back when they were new, but never since.) Probably 10 or 12MHz.
3) Commodore B-128 with drives and peripherals. But I ain't paying $600 for one. lol

After extensive research, I've revised my list. The 80186 is out.

The other two, however, are still in the plan. Add to that a Atari Falcon030, and Amiga 500, an Apple IIgs, among others.
 
i would say having the last surviving model of a phillips p1000 system

Is it yours or it's something you seek? I can't remember what that auction went for but I do know who won one (english is great isn't it?) of those high dollar model kits but I thought it was a PDP.
 
Well that's easy...

A PDP-1, the ultimate "space war" setup

Space, money and availability being the biggest obstacles. Not to mention a crew of white lab coats to keep it running and my own circuit on the power grid.
 
I don't know if this qualifies as a 'Holy Grail' or not, but if for some reason I had to give up all but one of my machines, I'd keep my Tandy 1000SX. Yes, I could live without the net.
