@keropi
Is that revision you're writing about the so-called Escom model ..? If not, then what/which revisions are these Escom models ? |

The worst ones were 1d.4 and 2B. Escom produced the 2B revision. Both of these had the bus timing fault (problems with 040/060 accelerators, though as Keropi suggests, your milage may vary) and the VGA tearing fault (problem with 31KHz display modes). The others are generally OK.

Have a 1d4 mobo in my A1200T which never gave me any serious probs except that the IDE controller is very picky about what cd-rom drive and cables you use and I often need to do one or two cold reboots for it to start when it's been turned off for a while

Only oddity i had amongst versions was the external scandoubler wouldnt work on one version. 1D4 and 2B were fine, but some other revision I cant remember (it had a full 40 pin clockport set), the system wouldnt powerup properly with a scandex external scandoubler in.(led stayed dim).

Thanks dudes for help. :-)
I was considering of buying an Amiga1200 computer. Maybe I'll buy one in near future. But do you guys think that the Escom A1200 model(s) are generally worth buying..? |

I bought one only about 2 months after its initial release, so i have an original Commodore A1200 HD/40 model. Never ever had a problem with it!.. i used it for 8 or 9 years solid everyday until late 2000.. and ive used it almost twice every week in the last year, and still no problems

I got my drive fixed by AT, but just before that I investigated a way to do it at home.... via the Aminet!!

@PaulyQ
Apparently you can also fix the AT motherboards another way, to make the floppy port like the commodore ones, but then you will also need a commodore compatible floppy drive, also originally from aminet: http://www.softpres.org/article:hard..._fdd_connector So there are 2 possible methods! |

@Calgor.... yup more than 1 way to skin a cat then
![]() I think the main problem arose with the Escom/AT boards in that the floppy drives where just standard PC jobbies as the original drives where going to be to expensive to produce. Soo... they payed for a courier to pick up and drop off my Amiga to fix the problem. How many other Amiga's from the latter days of the A1200 era had this done, wouldn't it have been cheaper to put in the right drives/fixes in the first place to save them the cash? |
