Technix - I used to have that same Pioneer receiver unit.. a friend bought it in Germany and forgot to switch the PSU over before plugging it in in the USA. I took it apart instead of fixing it, so I have a spare tranfo with the rectifiers still attached if you ever need one!
Ah nothing like an good old RPTV..
...
On bench, R->L: Dumb terminal (restoration ongoing), ZX spectrum+2 with ½ an IO interface, and an old PACE desoldering/soldering station.
...
I hope that's a cinnamon stick on your coffee, then again it looks like a shark is swimming on it.
I would ditch the Dumb terminal, it looks almost as big as my first one (VT-52), If you must have one at least go for a VT-520 (hard to find) or a VT-420, they are still vintage enough and you'll get 30% of your bench back

Rid of it? It's my pride and joy! It's probably one of the rarest British terminals (Internet-info wise) out there! I'm restoring it for my PDP-11 (when i find one, and I. will. )
I do prefer my coffee with some bite, but it is in fact a teaspoon.

They are goldmines of parts though. You just need a jigsaw to cut the huge case plastic moldings up into pieces small enough to fit in the roley bin.
Also in some of them the huge internal mirror is cute - it's a thin plastic silvered film, stretched tight on a light aluminium frame. That silvered film is useful too.
BTW, does anyone know what that optical CRT-cooling fluid actually is? Some kind of silicone oil, I think. But where would I find a product number and Material Safety Data Sheet? And a source to purchase in bulk? That was a lot of work, just to get 3L of it.

I've also found that those mirrors are quite useful for diy laser projects since the reflective film is not under the glass.
I'm wondering the same thing about the cooling fluid, as I have about the same amount as you. I was wondering if it would be good to use as transformer oil for the odd projects. I'll try and find it off of the schematics/parts list for RPTV's and such. What are you planning to use it for?
I remember reading that CRT projectors use glycol/glyserol so I guess projection TV's would be similar

Just wondering, since I obtained a bunch of CPLDs, is it worth it creating a PDP-11 clone, running at 50MHz, using a bunch of CPLDs, 6116 SRAM chips and a few modern microcontrollers?

to ChristofferB and other PDP-11 aficionado's:
I was going through some boxes in my other house a few nights ago and discovered a DEC PDP-11 hardware reference (softcover) in good condition. In the seventies my first mini-computer experience was with an 11/45 in a university basement. You never forget your first -sigh.
I can't remember the exact title as I do not have it in front of me but it fully described instruction sets, memory maps, front panel settings ect. and included some photographs, quite comprehensive. As I was thumbing through it I thought I will never use this again, I wonder if I should ebay it for the retro crowd as I don't want to just throw it away. The cover still has the original uni bookstore price tag $8.95 canadian dollars (1978 value). I will sell it for $20 bux plus shipping to anyone who wants it.
Lava lamps are now banned due to the fire risk, I heard. Which is fair enough.

It should be doable. There's a lot of PDP-11 info and documentation out there.

I would suggest you keep it and scan it up and share the PDF, instead of sell it.

By the way, maybe I would take the PDP-11 architecture and boost it up to 32 or 64 bit to make it at least a little bit more modern. That would make very good use of a few 100-pin and 144-pin TQFPs.
Hi been semi lurking here for awhile now, so I thought i would post my lab and a library shot.
thanks
