Happy birthday to my A1200 + question on accelerators

Just about any accelerator card from 030/40MHz up will make your basic A1200 look ponderously slow.

If you have the funds and can find one, maybe you'd be better off betting a Blizzard 040, or even a BlizzardPPC..
OTOH, if youre not interested in PPC, you could try to get an 060. I read somewhere hereabouts that a supplier was selling the chips 'cheap' and you could (maybe still can) get the Blizzard 060 cards with a 060 socket.

I had an apollo 1240 some time ago and it was a troublesome beast. Having said that, it was an early revision...

Hi there..

I bought an Apollo 1240/25 accellerator card in 1997 with 32Mb ram. This card also has scsi port as an option, but this port wasn't soldered on. I removed the original 50Mhz crystal and replaced it with a 80Mhz. This clocks the 68040 prosessor to 40Mhz. Now, the 040 runs at 62% higher clock speed. It runs hot like any other 040, but with a not too big cooling ribbon and a fan, it stays cool :-)

I have never had any trouble with my Apollo accellerator and i have used it both on rev  1d4 and 2b motherboards...

I don't mind using money upgrading my Amiga EVEN thoug the AmigaONE is coming. I'm not going to buy an AmigaONEbefore i know theyre cool anyway :-)

Hmm, my olt 1240/25 wouldnt work reliably at 33MHz, let alone 40. The FPU used to get really wobbly and give bogus calculation results.

Don't be surprised if one day you switch your machine on and it doesn't start. You got away with it for this long, but overclocking always catches you up in the end...

Another point; the Apollo SCSI isn't DMA based so if good SCSI is important to a buyer, avoid the Apollo series.
