I'm in the process of building a variable (~5-15) 1.5A power supply and my parts certainly were more than $15. Granted, I just bought some from Digi-Key w/o digging around for cheaper sources but I did all this thinking I could do MUCH better, price wise, than a store bought supply. I was wrong.

Fluke 9100A Digital Tester
by Chris_Hardy＠vie.co.uk 13 Dec '99

13 Dec '99

Hi everyone... I was recently lent a Fluke 9100a digital tester (with some POD's, yeah!), but the system is missing the system disk, so I'm desperate for a copy of it. Does anyone have one of these systems, and can either make a copy of it or email me the files that are on it. I don't know much about the disk, but I believe it's a MSDOS disk, so it should fairly simple to duplicate. Thanks Chris Hardy London (Yep, an emulator coder who got hooked on doing PCB repairs. Unfortunately it does suck up quite a bit of my spare time! If anyone needs anything "decoding" from Mame give me a yell)

Just multiply that by 3 for each plug you need for this unit. To add to what Scott said: I have a brochure for the CTF-1 (could scan if anyone wants), and according to it, the monitor is B&W. Perhaps the "Expansion Module" converts RGB to Composite Video? I too have a PAT9000. I have found the plug housings for $49.29, and $0.26 *per pin*. My solution was to adapt two of the Amp MR 36-pin connectors to the Canon connector - I don't use all 156 pins. Since the eBay pictures show lots of the Canon connectors included, you could probably cannabalize enough to work. That brings your per-harness cost down to about $10 per (not including the cost of your time). It is several hours' work to build such an adapter - that's why I consider the Pat9K a mixed blessing. On a similar topic, has anyone ever seen/have an Atari PBS-1 Simulator (for testing Atari Pinballs)?

Just for giggles I checked on the cable for the Z80 pod, and it was available too. 48-72 hours shipping time, $57.80. I also checked on one of the custom protection chips used on the z80 pod, but it wasn't available. Guess we know where to go for the cables at least.

The cable for the Fluke pods is nothing special. You can use a plain ribbon cable with a 40 pin plug on one end, and a 40 pin socket style plug on the other (don't know the name). The twisted pairs is very nice but if the cable is kept short it should be fine. I have this on a Z80 pod and it works fine, no glitches...

Great, thanks for the info. I had a bid on that one, but was outbid. The seller emailed me this morning and offered one to me for my bid price + shipping. I will probably go ahead and buy it, need to email and find out what processor it is for. Maybe he has an assortment, his auction says he has more. Anyone interested could email him and offer him $50 plus shipping for one, bet you would get it.

I bought one of these a while back. I'm surprised the guy didn't mention what processor this is for. The one I got was for a Z80. I'm guessing this one was too. If you see any others on ebay I'd snag it because they're great for doing quick tests on. I really like the quick trace feature. When you probe each pin of a ram chip, for example, the display will actually read A01, A02 or D01, D02, etc. It also has a feature called memory soak which tests to see how well ram can hold it's data for long periods of time - something the Fluke 9010a doesn't have. I also like the fact that it's really light and portable. By the way, that's really cool that you were able to find a part for your 6809 pod. I wish I had known they stocked parts for these because I needed a ribbon cable for a Z80 pod I have since sold. I got another one though.
