Burroughs TD700 Self-Scan early gas plasma display screen, with control unit and keyboard, Design Level 4 c1973.
Yay... we have a cursor (of sorts - with a bit of ghosting on rows 4 & 7)) after 4 days slowly notching up the variac to avoid popping old capacitors.
I had already replaced the power socket, a defective mains fuse holder, and 2 corroded capacitors on cards "A" and "T" in the control unit cage. The faint pixels shown up by the cursor occur in the same positions across the row so I'm hoping this may be a resolvable logic or driver issue in the self-scan control card, rather than a write-off self-scan module.
The identity plate is stamped for 240 volts, but the power supply test points for 5.1v, 12v, -12v, 30v, and -250v were all up to required values on 110 volts AC supply from the variac..!
The word is about, there's something evolving,
whatever may come, the world keeps revolving
They say the next big thing is here,
that the revolution's near,
but to me it seems quite clear
that it's all just a little bit of history repeating
The newspapers shout a new style is growing,
but it don't know if it's coming or going,
there is fashion, there is fad
some is good, some is bad
and the joke is rather sad,
that its all just a little bit of history repeating
.. and I've seen it before
.. and I'll see it again
.. yes I've seen it before
.. just little bits of history repeating
Some people don't dance, if they don't know who's singing,
why ask your head, it's your hips that are swinging
life's for us to enjoy
woman, man, girl and boy,
feel the pain, feel the joy
aside set the little bits of history repeating
.. just little bits of history repeating
.. and I've seen it before
.. and I'll see it again
.. yes I've seen it before
.. just little bits of history repeating
[Propellerheads & Mrs Shirley Bassey]
The original IBM PC, the first one. It run on Intel 8088 @ 4,77 MHz. Not happy to say that I had one, it was my first pc...
I like old computers. But I have a teeny-tiny home office, so I can't have all of them set up all the time; I need to multi-task. What to do? Organize them into the Retrocomputing Closet of Doom, so I have easy access to each piece whenever I fancy pulling it out!
From bottom to top: MicroVAX 3100, Apple ][ Plus, Dell Optiplex PII, Apple IIgs, Commodore 64, VT320 terminal, Sun SPARCstation LX, and an overabundance of keyboards, keyboards, keyboards.
The scary thing is, everything works.
Still working!
The add-on board provided SLOW/FAST modes switching, making this ZX80 like a ZX81.
The side switch allows screen black/white reverse.
IBM's PCjr was a failure, or so I gather, but this one was more successful. Released only in Australia and New Zealand, I spotted a couple at a garage sale many years ago, and had to grab them. There used to be a cartridge-based version of Lotus 123 for this computer, on two cartridges, which always impressed me.
Con "soli" 10,7 kg di peso, l'Osborne-1 fu il primo computer portatile disponibile sul mercato.
With "only" 10.7 kg of weight, the Osborne-1 was the first commercially available portable computer ever.
My Amiga 600 with built in Flickerfixer by Indivision. I removed the useless RF modulator, modded the case so that a VGA port would fit.

I was a Commodore user and never had much experience with the Apple II world. I'm sure that these are digitized on archive.org or similar sites but if anyone would like these they're at the Habitat For Humanity ReStore in Westminster, MD.
Entre estos viejos equipos Apple en el Little Apple Museum también hay un NeXT (la compañía que fundó Steve Jobs al ser despedido de Apple, que acabó siendo adquirida por Apple años después).
Memories from the '90s. While cleaning a forgotten place in my house, I found this panel that I made during the '90s, collecting pins and stickers from events. It's fascinating to see how many of the ideas of those times are now in place. Technology runs fast, but the adoption has its rates.
Nonetheless, if you do not imagine and invent, you will never know where to go. It's just a matter of time.
