I have more then I need. All the working ones are HP w/color crts, and as far as older, verifiably vintage tools (right down to the 680x0 processor in either) I have to admit I favor them as a brand. Call we an oddball, weird egg, badges I wear with pride.
But who could resist the allure of the newer ultra portable, even handheld units (some with bandwidth or sampling rates to 50mhz). I'm a big cheapo. But there's no real reason to agonize over a 65 - 200$ or thereabouts acquisition. It's a bit tiring to wade through the piles of availability. I favor a desktop unit, larger screen (but not always, careful). But most of those need wall current I think? The convenience of a handheld battery powered unit obviously has it's benefits.
I will always love and dote upon my color crt based HPs. But the damned things are so heavy, so unwieldy. Judy-Jude knocked my 54111d over, hit the paved floor, shook the house. And still works! Built to withstand an atomic bombardment.
I’ve read with great interest, over the past short while, a few interesting
articles on the history of the Intel 8008(officially released in April
1972) as it was the forerunner of what was to become the personal computer
industry. And done with less than 4000 transistors. I saw one at a computer
shop/store in Toronto in the latter 1970s’ but had no idea the seminal role
it was to play in microcomputer history.
Happy computing!

I know this is a real long shot but is there any chance someone
has a copy of the original distribution of the Amoeba OS from
the University in the Netherlands? Searching the web finds only
the current version which runs on X86. I am looking for the
original which also ran on Sparc and (of the most interest to
me) the VAX.
Remember when they said now that we had the web nothing would
ever be lost again? :-(

Clearly all or virtually all chineseum, correct?
That being the case, um, what type.of.quality can be expected? Some are fairly cheap. I guess thenworld isn't to be expected.
MTM Scientific (Clinton, MI) offered modern redrawn IBM PC 5150 base board
and a Full Kit, at one time.

While he is no longer selling separate blank 5150 boards,
you could inquire about Gerbers.

Just out of curiosity, what are you using this board for? The IBM 5150
uses at least three different mother boards, 16K, 256k, and I *think*
512K soldered in RAM. Each is expandable to 640K with 3rd sourced RAM
boards.
I should have (somewhere) at least one of each. I also have several 5150
complete units including keyboard (not so sure about the monitors.)

The board itself, including the traces, has to be in good shape. Don' t care about it's functionality, or even if chips are missing. An actual IBM product, regardless of revision. Might consider an entire 5150 box. NJ.

^^^^^^
That is going away, too.

As of the past few days, that may not be the case anymore.
