Yep, it’s all about whether you’ve burned the fuse bits or not. Definitely worth trying to read the chip out though! Of course if you have the VHDL or Verilog source, it’ll be much easier to do a circuit design...much less reverse engineering required.

Most interesting: Arcflash, FX2+PiTubeDirect Tube/Cartridge adapter, USB cart interface.

I've been tempted to downsize my car to avoid such issues, but then I would have to make more trips ;)

Do what I've done. Get yourself a van with no windows in the back.

I've now got a mobile storage space for some of my collection and my other half has no idea whats in there (actually she probably just imagines the worst) :)

It's at this point that I cry "amateurs!" and admit that I might have won a somewhat large eBay retro auction a few months ago... which was so large that I had to hire a storage unit.

I do not recommend this course of action. Storage units are expensive and flogging stuff on eBay is time-consuming! Family members tend to view your hobby with a mixture of amusement and despair.

I do, however, totally understand the warm, fuzzy feeling you get from having a van full of old computing equipment. Which is yours, all yours... :)

The van is just an overflow area for my storage locker and garage :)

...a bunch of PCBs as part of my IntegraB remake project. Annoyingly I identified a track routing error before I even received the boards, but easily fixed with a couple of patch wires. Will be busy tonight :)

A ZX Spectrum OMNI HQ laptop. It may be the oddest thing I own, but it's quite a lot of fun.

another Sinclair Spectrum - needs a new power socket fitting and probably the tape desk belts changing, but it does work - that gives me three Spectrums now, a rubber key 48K, a Plus 48K and now a 128K plus2.

Love this. Ordered one myself. Only a 60 days wait and I can play with this. Time enough to think of how to explain this purchase to my wife. :D

Mine took less than 30 days to arrive, although I think I might have been a bit lucky with the timing of the placement of my order. I ordered (from RetroRadianonics) on the 23rd of Jan and it arrived on the 19th of February. It was posted from China on the 1st of February. The postage to Europe took 18 days. Both packages (screen and laptop) arrived at the same time.

yes... I felt a great disturbance in the Force as if millions of voices suddenly cried out in terror and were suddenly silenced.

and I've finally got myself a Commodore 64 - condition is pretty good, bit yellowed and needs a clean - non-worker at the moment, just horizontal lines on the screen along with the border (suspecting CIA #2 has bit the dust) and needs a missing spring replacing on the F1 key - got parts on order so will have to try and find the soldering iron (unfortunately this one has the chips soldered rather then socketed like the earlier models)

You just need a regulated 5V DC PSU, as the 9V AC part of the original Commodore PSUs rarely fails. You do need to modify the existing lead through so that you still feed the 9V AC power, but disconnect the +5V DC from the original PSU. Then connect in the +5V DC power from a modern PSU.

Having said that, my (possibly flawed) understanding is the later larger rectangular Commodore PSUs are a bit more reliable compared to the earlier, smaller type. Neither PSU was actually made by Commodore, they were made by third party companies that supplied Commodore.

I got one of these PSUs for my C64. Not cheap but hopefully I don’t have to worry about failure!

will be looking at either getting a modern PSU or a C64 power saver (anyone have a UK source for these?)

Electron +1, +3, AP6, Mega Game Cartridge, 2nd drive adapter, rom/ram (dfs/adfs e00), 64k master ram board.

Master (assume 128 but will open up to check psu caps and see what we see) at very least needs a new black strip along rear ports as a small chunk missing).

Yep and everything socketed by dave h and tested. Bloody glad I had an old blitz kicking about that dave H wanted and appear to be rather rare now). Ok I added the AP6, rom/ram and 64k master ram as thought they were no brainers. Will be adding an AP5 when dave does his next run. The master I plan to go Pi 2nd processor, NULA, Datacentre (for moment ordered a cheap user port sd thing to get me going)
