The Vortex has 387 socket, FDC and IDE connectors, 4 simm slots (max 16mb). The vortex enables the amiga's other 2 (or 3 in the case of the A4000) ISA slots so you can add vga card, sound card etc.

I ordered them on... 3rd feb? So that's 13 days to make/ship by standard mail. Not bad! Solder resist isn't perfect, but that's fine.

Those valves look great on display. I shall have to 'rescue' some of mine from my shed and put them on show in my man cave.

I have one very similar to the valve in the centre but mine is on a B5 base with an indirectly heated cathode. Yours being B4 points to it being a directly heated cathode, probably with a 2v heater. What is its ID number - L2 ?

Why do I keep collecting Acorn gear? I'm going to need a considerably bigger man-cave. :?

I can’t find any other numbers on it apart from the type, Mazda U65/550.

I do like valves, swastikas and all sorts (AM = air ministry = British equivalent for balance :oops:) on them.

I think this UV-199 is my oldest at the moment but I have another one on the way from the 1920s too.

Thanks for the detailed photos.

The U65/550 is a rectifier valve from 1929. The one I thought it might be was an audio triode.

I'll definitely dig my valves out and photo a few. I have one which is held together with a nut and bolt inside the glass envelope!

My earliest are from the 30s but the bulk of my valves date from the 50s.

(well yesterday)

At the Recursion Computer Fair charity stand I picked up an electron of unknown workingness and slightly randomly a Casio Fx-8100 calculator, which has watch functions built into a scientific calculator.

Also got home to discover a very cheap MP3 player had arrived . It can play WAV files, so it's an experiment to see if it can be a very poor mans cassette player for loading things.

had a BBC Micro I won on eBay turn up yesterday - Model B with an Issue 4 board and a Computer Concepts Graphics ROM - case in in good condition, just yellowed / dirty, screws missing and the feet have fallen off (were with it though so I can reattach them). Looks like it has been repaired at some point in the past as some of the memory ICs are socketed and apart from the Graphics ROM, no upgrades have been installed

Good news was it did power up with the normal beep and Caps Lock LED on - responded to the keyboard turning Shift Lock and Caps Lock LED on and off, but one of the X2 capacitors went pop so didn't test any further yet (already ordered replacements before the BBC arrived)

Hopefully going to have time to replace the capacitors over the weekend and see if it is then up and running properly. If all is working properly, going to look at the options for adding a SD card as storage

Hi,

a month ago I finally found one of these, so I reached my 2018 goal much sooner than expected... :D

My Philips VP4xx set is complete now... 8)

Now the even harder part to find,, the discs... :(

Edit:

I forgot to post this part:

Looks good. I hope your copy of the user guide is in better condition than mine. I did scan mine and it is available at 8bs (http://8bs.com/othrdnld/manuals/applications.shtml). The damage is pretty obvious but at the time there didn't seem to be any version archived anywhere so I thought better mine than none. The first ten or so pages are the worst as they got stuck together and, in some case, some of the text is missing. Would you be up for scanning a few pages from yours to construct a hybrid effort? As I said the first ten or so pages are the ones that would benefit most and the quality then gradually improves as the book goes on.

On a realted note I did also OCR the book and now have a copy in DocBook format which can be processed into either PDF or HTML which I hope to submit soon.

And, editing for clarity, I was referring to the BCPL user guide.

Unfortunately all my retro stuff (and nearly everything else) is boxed up in storage until early April earliest. Once I get it all back I will do the first 10 pages or so.
And wow. That scan is big!!!
