Technical questions for the MPC2000xl and the MPC2000

So this is a question that might simply be answered "Not possible", but the hardware hack in me is inclined to ask: is it feasible to cram an internal MCD reader (in place of the floppy drive) into a 2000 classic? I know the 2000XL has this ability, and that the 2000 can have an external reader via SCSI but anyone hacked this to a more ideal solution? My initial thought is that whatever internal interface is in the XL might be ported over to the classic, but that'd require either a donor XL or a spare part. Ideas there?

You can put a SCSI card reader inside a 2000 -- you just need the right kind of cabling to hook up the SCSI on the MPC to the Card Reader.

However, you will need to make the CF card bootable with the 2000'sOS so the MPC can load the OS upon startup.

Yea soldering isn't necessary, you just have to know the connector secret that is sold/held by SCSI4Samplers. I am scared something is going to protrude from the back of my Classic and $50 isn't cheap just for cables and connectors. I can make a contraption to work but I am not familiar with how to deal with the SCSI port (if it can be moved or not?). That's my only hold up. :?

Connector secret?
You mean the one he showed in this thread
viewtopic.php?f=1&t=115659&start=0&hilit=internal+drive+install+2000
when he posted this pic

All you have to do is make that cable with the two blue ends, mount the drive in the floppy slot and I think you need a male to male SCSI cable.
All I said was it's possible with soldering, I didn't say it's impossible without soldering. :wink:

Oh yea, I wasn't responding to your post. I was just saying it was possible (in case the poster didn't know).

What confuses me is how do you get the cable into the MPC from the two ended (male & female) 50 pin connector? All I can think of, if the SCSI port can't be moved back, is to tuck the SCSI cable under the frame on the back of the MPC to run it back into the inside or cut a slit in the case :?:

Fung, if you noticed in the pictures, how the SCSI cable is routed back into the MPC isn't shown, to me that is the tough part. Everything else is simple (IMO).

No doubt he made it quite ambiguous. If people could figure it out easily he wouldn't be able to make any money. Hell, he could have even lied in that picture to throw people like us off. The me the most important part is to the right of the blue/grey ribbon
scsiforsamplers.com wrote:"This is what ties it all together- a custom cable that attaches to both DB25 connectors in the back and becomes part of the MPC. The female plug sits exactly where the original female DB25 was and the short extension connects to the new DB25 in the SMPTE hole. This cable never needs to be removed."

I think what he might be doing is removing the original SCSI and moving it to the SMPTE hole, for the sole purpose of getting it closer to the MCD? Like it shows the blue female DB25 shown becomes the new external SCSI port. You then extend your SCSI 'chain?' I guess you could call it to reach the MCD drive with another long ribbon cable. I think this all happens internally but the small custom ribbon isn't hooked up or shown in the pic. It's just like the destructiv mod in that you are tapping in to your current SCSI to make your external internal. Destructiv split his ribbon into 25 wires and soldered each one, where as scsi4samplers made a new ribbon that extend the SCSI to a new location and then patches it to the MCD. I believe the reasoning behind doing this is 1)even if you could get a long enough ribbon to patch from the SCSI to the MCD drive, there would be no room for it because of the limitations of different connector styles and the circuit boards etc. in the way. and 2)You still get use of your external SCSI port.

Oh yea, I didn't want to bust anyone's bubble (trying not to cross the forum line) but the pictures are totally bogus IMO :?: I think the DB25 plug in the SMPTE port should actually be inward because that is what becomes the internal SCSI port.

The moving of the external port is what gets me, I think it's impossible (doesnt seem "safe" to me). Inexpensive to make, but the key is getting it to function properly.

I wouldn't "move" my SCSI port if I did order "the" kit because I do not trust it will work and I only have one MPC (my personal opinion).

What is your stance on it (anyone)?

I think the color might be misleading as well. The black DB25 in the SMPTE shown may be the same as the blue one on the ribbon shown. Seems like he's utilizing female DB25 connectors because they also have male connectors on the back, not for SCSI device hook ups.

I think it could face either way because like the pic says the blue DB25 has a male on the back so you could in theory plug a second female DB25 from the MCD ribbon inside the case. The small ribbon probably goes from the pins on the circuit board (where destructiv soldered) on the current SCSI to the new second DB25 in the SMTPE hole. Like I said I think this is merely to make it closer to the drive and allow for a working external SCSI as well (hijacking the wires stops the external from working no?). The only trick would be to get the ribbon seated on the circuit board to stay put... hot glue gun? This is not as complex as it seems. Like jellyjim said in the destructiv thread

Awww man, great idea :idea: I think you may have solved it, whose the first to give it a shot? So that would make two external connections and one internal right?
I was thinking the other side of the male was a female but I wasn't 100% sure it would connect. It's worth the risk, I can't break anything. I'm gonna order me some cable, connectors and going for it.

Thanks Fung, and whoever started this topic.

*Edit* Found some non 2k(xl) based threads. The one involving the 3k may be exactly what we need!

http://shop.ebay.com/?_from=R40&_trksid=m38&_nkw=ide+scsi+bridge IDE-SCSI Bridges, we need one for 36 dollars.


I am curious, I may not have read the thread as closely as I should have, because it seemed like something that was obvious to me was being questioned and debated, this isn't criticism or being a confrontational, either.

What I am darn near certain is going on is that he made what is essentially a loopback cable and utilized a custom end, and probably not all that custom at that, it is just a db25 (mpc scsi) to 25pin zif connecter of some sort, although dont quote me on that. Then a connector from the flash drive to that socket. What I am curious about is whether he is using a strictly scsi card reader, which is kind of expensive and perhaps dictating his 100+$ dollar price tag, or whether he is using an ide flash card reader, an ide-scsi adapter then just adding the end to meet with the socket, probably using thinner cabling more convenient for the internals of the mpc. The ide-scsi adapter option is significantly cheaper and I wonder if thats the deal. I do not remember exactly if the 2k classic will work using the adapter or only the 2kxl will as it has support for ide connections, and I dont remember if there is an ide port on the bord itself or using the adapters.

I have been thinking about doing this for a few weeks, but with the loads of threads and all different suggestions for equipment, and most of them involving the xl, which has support for ide in the 1.20 OS, it was kind of hard to decipher what I want to buy considering that I have the classic rather than the xl.

I did come accross a thread somewhere for some other kind of synth of some sort that listed a very cheap ide-scsi adapter, on the order of 10 or 11 dollars and an equally cheap ide card reader. I wish I had bookmarked that because if for the classic thats all we need to use, then shit why dont we jump on it. *See links at top*

I mean I know that the scsi for samplers dude is out to make a buck, but times are tight and I am certain it can be done for much less and with minimal work involved. I am not chicken to try something however, I dont want to buy crap and have it not work.

Now that I mentioned that thread I am going to look for it.

Peace and love Kids.
