I decided to finally put together a A1200 "the right way". I have a vanilla (PAL) 1200 but I need to stick a good 'ol 50 MHz "monster" accelerator card, more memory and a HD in it to make it usable.

I'll see what I can do.

you need to stick a compact flash card in it. shop shop!

In terms of pick-up, I'll be at Solskogen for sure ;) And I have friends going to pretty much every other party around, so it should be very possible to avoid postage and such.

(oh, and I'm willing to pay of course -- something I forgot to mention in the first post :)

You can check out amibay.com and the hardware sales forum as well. And as bstrr said, get a compact flash for it instead of a HDD (you really don't need that much space anyway)

just a small tip. the vanilla 1200 casing was bot really designed for the heat generated by 060. the heat is not generally a problem, but anything you can do to improve the situation of airflow is probably a good idea. some people attach small fans and heat sinks to the board (which is probably overkill, imo) but a quick and easy way to improve airflow is to modify the trapdoor, something like this:



this guy has used some kind of metal mesh, but I simply melted holes in a similar pattern using a hot welding iron ;) i also placed a couple of small stick-on heat sinks to help draw the heat away from the cpu. it did drop the average temperature considerably.

Installing a bit higher rubber feet on the case - like in that photo - helps some. The turbo stays quite nicely put without the trapdoor anyway :)

I've got a blizzard 1260 with 16mb.. but it's not enough to run tbl demos which all need 32 or 64mb ram.

Been using an 060/50 (stuffed with 2 SIMMs and SCSI kit) since the Middle Ages with original trapdoor on, no heatsink nor fans and no heat issues at all.
But yeah, higher rubber feet or modded trapdoor cover might be a good idea.

I had an 040/50 and it was way too hot for the amiga.

If you didn't change all the capacitors of your amiga , you should. the CMS used in late amigas (a4000,a1200,a600,cd32) was designed to last 15 or 20 years: so almost all amigas that haven't been refreshed this way tend to be unstable now, have sounds troubles or worse... better have a stable amiga when you code.

... that guy (cosmos) sells (on ebay and elsewhere) new sets of capacitors corresponding to the different models and versions of amigas for 5 euros, and also can do the job.

and as everyone know, 68040 are known to get way more hot than 68060, which barely get hotter than a 68030 (most 68060 users I knew didn't even have a cooler on them)

is it possible to over clock the 060s then?

I had an 040.. not sure what happened to it but the whole amiga got trashed :( Need to get another now before the price gets too high, I picked up a vanilla 1200 a few years back. Not really had time to fire it up though. One day!

psonice: I've overclocked my Blizzard1260 to 66MHz, and it runs fine (in a towercase though) with some extra cooling.

@krabob: Are the caps of the A4000 mobo all SMD?

I replaced all the caps of my pc mobo a few years back, and they weren't SMD - one hell of a job to do without ruining the PCB ;-)

(first: on my last posts: CMS==french for SMD ). (second: I am quite newbee in electronic.)
But I can answer that:
for most aga amiga pcb, there is about 15 SMD capacitor and 4 aluminium electrolytic capacitors, and that cosmos guy recommend to change them all ( so that you don't have to worry for years), but there's a lot of debate in the french amiga scene about the need of it (some capacitors don't need to be changed)
There is a site somewhere with the list of all the versions of each amiga PCB and references for their capacitors... can't find that quickly.

cosmos does a great job on his blog, very didactic, I learned to do the job myself following this. (well, it's in french)

The guy also does special kickstart roms, and overclock cards, here an appolo with a 68060 at 100Mhz !

I've had a Blizzard 1260 for ten years and it's never needed any cooling. I have the trapdoor lid on. Sure, it gets a bit warm, but not enough to worry me. My old 040 card, however, came with a heatsink and an annoying fan and it still crashed from overheating all the time.

@gloom:
I hope you braced yourself for ridiculous and downright offensive prices for this 1260 accelerator board. Usually they don't come that cheap (talking EUR 300.-- and up) unless some scenish "insider trading" takes place.
