Umax Takky?

I'm new to the world of modifying Color Classics (but definitely not new to Macs!) I've been doing a ton of reading here, at the old forum, the colour classic faq, various other sites and I've decided to build my own takky.

However, I've never once seen metioned anyone using the alchemy board from a Umax C500/C600. Just curious as to why this is. Possibly because just about nobody bought the Umax clones therefore nobody's had the board to try? Maybe it just doesn't work? I'm guessing it'll do the trick just as well as a 5400/6400 board would.

Any thoughts or advise anyone? Thanks!

I can't think why it wouldn't

I can't think why it wouldn't work, but given the labour involved and the cheapness of x500 boards these days, I'm not sure it's worth the possible hassle in the event that there is an unexpected 'gotcha'.

I think it'll work too so I'm gonna try it.

The reason I arrived at using a C500 board was simply because I have an old C500 system somebody gave me - and free is a good price!

Umax Alchemy

Does the Umax board have the same board-edge harness connector that the 5xxx/6xxx boards do?

Can it take the Apple TV/Video/FM/whatever boards, too?

If so, I'm going hunting for a C500!

Peace,
Drew

I'm not positive, but from what I can see on the one I have the answers are no and no.

Anything is possible

It could work but as Stuart mentioned why bother ? The Mac boards slide in. The Umax board is the same but not the same if you know what I mean. It's not a slide-in type board with the contacts on the edge. Besides PPC logic boards are cheap and plentiful still.

I have a C500 and I thought about building a MegaBlock case for it since I saw an old Dell at a thrift store with the exact same case with the exception of the faceplate. I also have an old dead IIcx I considered putting the c500 gut into.

C500 vs 6500

It occurred to me that there are few reasons why I'd choose a 6500 over a C500 for a takky. I haven't looked at a Umax machine in a while but I don't recall any internal video so outputting to the CC CRT involves more work. For me bus speed was a factor so while I had a 6400 motherboard on hand, I purchased a 6500 motherboard. I felt a higher bus speed was important because a G3 cards speed is determined by the bus speed of the host computer. Also I wanted to run iMovie and try importing digital video from my DV camcorder. I also wanted a machine with 2mb of VRAM so I could get millions instead of thousands of colours.

The Umax C500/C600 logic board is 13" X 9".

The 6400/5400/6500/5500 logic boards are 8.25" X 8.75" (ignoring the edge connector).
