An Amiga 1200, plus various games and software:

Image

Most of the games and software don't interest me at all - my main interest was the computer itself, which hasn't gone yellow and doesn't seem to be missing anything:

Image

The PSU is hideous, and is in desperate need of a shot of Retrobrite. It's large and heavy and looks like something that someone knocked up in CDT classes at school:

Image

I will be stripping it all down and giving it a good clean. The seller didn't say that the unit had been recapped, so I'll need to send it off to get that done. I have a brand new mouse to use with it, along with Kickstart 3.1 and Workbench 3.1, and will probably buy a flash IDE drive (Transcend DOM) to use as internal storage (I could use CF, but I've had bad experiences in the past; using DOMs with my Acorns has been problem-free). It will probably be getting an accelerator card at some point, with an RTC, plus a USB expansion.

I did give it a brief test to make sure it works, and it appears to be fine: no strange smells and no smoke.

Random thoughts:

* Why no power switch on the computer?
* Why are there two blank keys on the keyboard?
* Why is the PSU so vile? It would be nice if there was a modern alternative.

Which version is the PSU?

Commodore appeared to reuse the same basic shape case, but used different screw positions for the various PSUs for the various Amiga models...

Some use a normal mains frequency transformer, others use a switch mode design.

Please post some photos.

Apparently I will need a second or even third disc drive in order to avoid constant disc swapping with this one. Pity it doesn't make use of the 128K RAM rather than the standard 64K. Ah well, good excuse to buy another drive...

Having done some reading last night and inspecting the hardware further, I have an A1200 (revision 2B motherboard) with an A500 PSU. The part number on the unit is 312 503-02. This page classifies it as an A500 type 1.

Couldn't you use a PC PSU, as it doesn't require AC power (unlike the C64)?

It is possible, though I'd much prefer not to have a metal box lying around. The main issue is the non-standard square 5-pin DIN connector used by the power cable:

PSU plug

These are as rare as hen's teeth nowadays.

Since my last post, I have managed to take the PSU apart. Oh dear. What a piece of junk. It makes the ones I made in CDT classes in 1992 look state of the art. I had to use a drill to remove the circular bits of plastic above the screws (the four round bits in the first picture of my previous post). The PCB is currently in the garage out of harm's way and the casing is in the bath waiting to be thoroughly cleaned.

I found another one on eBay, so I bought that and I'm going to remove the innards and stick a modern PSU in it, reusing the cable from the PSU to the Amiga with its weird connector. I may also spray it black to hide some of its hideousness.

When I get a chance, I'll take a photo of an A1200 PSU next to a A500 PSU and a A600 PSU. Then I'll then post it up here.

My haul today, collected from the mother-in-law's attic (and partly Acorn related) is:

Atari ST1040F computer
Commodore 1084S monitor
Philips CM8833 monitor (already have his younger brother, the CM8833-II)
Atari SM124 monitor.

All in unknown condition but were working when last used in early 2000s.

Pretty pleased.

Any gotchas I need to know about before I switch any of them on?

Some spare power plugs for the Atom, since they seem relatively hard to find I thought I'd get a few along with some other bits (never know if/when they run out of stock).

Have you got a PC (preferably running Linux) with a spare ISA or PCI slot?

PM me if you want to borrow a card and suitable leads for imaging (assuming you are in the UK...)

I haven't got any photos of it in action, but I'll see if I can get some and post them in a suitable thread elsewhere to avoid cluttering up this one.

I've been using the XRGB with my newly-acquired Amiga over the last few days, and the experience hasn't been entirely positive (to add to a corrupt Workbench 3.1 "Extras" disc and Compact Flash cards that my PCMCIA adapter doesn't recognise). There are weird artefacts on the screen, which randomly come and go. If I move the unit, sometimes it resets itself. At one point, it decided to move the picture half-way across the display and corrupt the top centimetre or two; nothing I tried (including a full reset to defaults) could get it back to normal. I don't know whether it's the XRGB, the PSU, the SCART to 8-pin adapter, the Amiga's SCART lead or the Amiga itself. Further experiments are needed.

The XRGB is far too complicated for me - there are dozens of settings for you to tweak, and the documentation isn't great. Ideally, I want something that's plug and play. I was looking at an OSSC last night, but there's a waiting list until October/November. I imagine I'll end up getting one and possibly sell the XRGB if the OSSC proves more suitable.

Vince- Have you tried an 8200 with the cap/resistor fix to remove the artifacts? Having used both that and an Extron DVS204, I'm happier with the gonbes!

Alas, I got rid of my 8200.

I tried the Amiga with my DVS 204 yesterday, and, yeah, it wasn't great. The DVS 304 was even worse. I tried with both a Sync Strike and a gscartsw between the computer and the Extron; the former gave a slightly better picture.

By messing around with the screen settings on the Amiga and resetting the XRGB-Mini again, I got a picture that was at least in the right place on the screen, though it still suffers from noise. I tried it with an Electron and a Beeb and the picture on those was excellent.

Anyway, there were still a few OSSCs available on videogameperfection.com (still one left at the time of writing), so I ordered one from the batch due for delivery in October.
