I recently purchased an Indivision MK3 for my A1200. When it works, it works beautifully. However, mostly it is not detected (no signal to the monitor and the Indivision software does not detect it). I assume the problem of not being detected is that the main Indivision board is not seated properly over the Lisa chip. I've tried re-installing it, making sure it's snapping fully on. Finally I got it to work. But when I turn off the A1200 and turn it on again, it's back to not being detected. I've pulled it off and re-installed it so many times now. Just got it to work again after removing and re-installing about 10 times but alas, it is not detected again after I turned the machine off and on again.
Any tips or advice on installing it or anything else? I'd like to be able to get it reliably working all the time.
I bought my A1200 new in 1994. It's in the original case and has been well looked after. Current specs are:
- Kickstart 3.1 ROMs
- Blizzard 1260 accelerator with 68060, 64MB RAM and onboard SCSI controller (have tested with and without the accelerator, it seems to make no difference as I can get it to work with the accelerator)
- 4GB 2.5" IDE hard disk (next job will be to swap for a 4GB CF drive)
- old converted PC power supply which has been rock solid (also have some old A500 PSUs but they're starting to get flaky)
- connected to a 17" AOC LCD monitor via a pretty decent quality HDMI-DVI cable on the Indivision HDMI port (also have an old 1084S CRT which I have used to run the Indivision software to confirm it's not being detected).
