I found a CDTV!

I'm sort of a vintage computer collector, but amigas have been a big hole in my collection... until now! I literally found a CDTV in the dumpster behind a bar (don't ask...), I suspect it was being used for karaoke. The remote doesn't work but the CD drive seems fine and the unit is in great condition! None of the accessories (keyboard/mouse/floppy etc) were anywhere to be seen however.

I have no experience whatsoever with Amigas at all so this is somewhat of an uphill struggle, but my plan is to get this working like an Amiga 500. I have pretty much no money but lots of free time and PCB etching skills, so I figure I'll build most of the stuff I need. I just need a sanity check on all of my plans, since I have no amiga-specific experience but a reasonable amount of general computer/electronic experience.

First off I guess I need keyboard support. Amiga keyboards are expensive on ebay so I'll just make a ps2-to-amiga adapter. I'm going to use the one supplied with the EPIC-1.3 pic programmer since I have lots of PIC16f84 lying around - http://aminet.net/package/docs/hard/epic13 - obviously with different pinout for the CDTV. Does this sound reasonable?

Next is mouse/joystick support. Looking around it seems nobody has a cheap brickette so I guess it's gunna be a case of adding standard 9-pin ports (like : http://web.archive.org/web/199902091...-joystick.html ) then building a ps2-to-amiga adapter (like : http://eab.abime.net/showthread.php?t=66443 , again because I have a lot of PIC16F84s lying around). Again, does this sound like a reasonable course of action?

Next comes the thorny issue of kickstart upgrades, I'm told that the CDTV can accept 3.10 provided the expansion roms are updated also. This means I need 3x new EPROMS. I have no experience programming EPROMS of any type. Are ROM programmers easy to build or would I be better getting someone else to do this for me?

Finally I think adding a SCSI hard drive would be the icing on the cake. I've missed the amibay bulk CDTV SCSI interface order by a matter of weeks ( http://www.amibay.com/showthread.php?t=50703 - d'oh!) but I can easily etch the dual-sided board myself. All I need to know is if any version of the 33C93 controller will work - I see various different versions of WD33C93, AM33C93 for sale on ebay - I take it they're all equivalent?

They are available NOS at about 25. Is that too much?

NOS CDTV remotes are available in practically every Amiga shop for about 10. Where they came from (i.e. there have to be many times more remotes than there are CDTV's!!) I don't know but I've got about 4 here still in the wrapping.

Added mouse/joystick ports and built a PS2 mouse adapter. It boots into workbench from a CD just fine!

Lucky bastard.

I'm still hoping one day I trip over an a4000 with 060 and ppc while talking a walk in the park.

What do you think my chances are?
