What flashes!? However I thought I was going to need a crowbar to get this Agnus out! The one in my other box came out very nicely, but this guy put up a real fight. I didn't get around to rejumpering or trying out the LIVE! board. Will have to wait til the next time I'm in there. mr bill

Bill, I take it you got your EXSM from Jameco and it worked ok then? Don p.s. I got mine, but haven't had the time to open things up yet.

Don The first Aggie (I have two boxes) came out with the greatest of ease. The trace cut caused a moment of fright when my 60lb German Shephard decided to say hi to me! Thank heavoens nothing else got cut! My second box at work (#1 is rev 4.2, #2 is rev 4.3) must have had its Agnus cemeted in there. We ended up persuading it with a flathead screwdriver at each end before the tool could get under for a good pull. That Agnus won't be seeing a motherboard any more. The two boxes are both doing fine without any new strange looking gurus. While I was in there, I had also just bought a pair of GVP controllers and a Syquest 40MB removable. That caused more fun and games as I found out that GVP had given me their 68030 board installation software instead of their hard disk stuff! I ended up getting into their bboard to grab their latest scsi device and script arcs. I backed up both my Quantum 80mb drives and reformatted. By the way… does anyone out there want me to do a write up on how I converted (well actually still converting) over from a 2090 and 2090a to GVP controllers? I'd also like a pointer to a scsi cable with the 25pin db on one end and the 50pin internal (telco) on the other end. I want to stick that Syquest into an expansion box so I can schlep it back and forth between home and work. mr bill

Bill, Yes, I think a file on what you had to go thru to do the conversion may be helpful for others, so if you want to write it up, we'd appreciate it. The 50 pin end…you said telco connector…are you sure that's what you need? A telco connector is an Amphenol…much like the Centronics connector on most printers. They're used for external hookups on much of the SCSI gear, but the internal connector is usually a 50 pin Berg connector which mates with the double row of 25 pins on the controller/drive. You could probably find the cable you're looking for at a Mac dealer's but be prepared for a few $$ in cost. Don

Cables, cables, cables… I have a very strange set up here at Artemis. A Microbotics daughter board SCSI controller (internal) has a 25 pin connecter. I have a cable that passes 25 pin to 50 pin connecter. This attaches to an external C LTD HardDrive. This drive has another port for daisy-chaining, so I also have a 50 pin (Centronics) to 50 pin (Seagate) cable from the second C LTD port, back into the Amiga, ending up at a ST277N Seagate. Call Redmond Cable (you know, "The Weird Cable Place"), and explain to them EXACTLY what you want. They will whip one together ASAP.

Good luck with the tire wrench Mr Bill! Hilary

Hilary Its a done deal. It only took a flat head on each end to get the sucker started. mr bill

Good… Mr Bill – you are commended for your efforts! Another subject……. Can you – or anyone in the Forum – recommend a "BLACK BOX" which either will go into the AMIGA 2000, or reside nearby, which will take IN composite video, freeze a field or frame in memory, and then have the ability to record what the picture is on one of the machine's disk drives ??? All the best………. Hilary.

You changed the Agnes chip without changing the jumpers? Ron
#56050From: William SharerJul 6, 1989 4:22 PM
Ron Of course I changed j101. What hilary was talking about was the j300 which decides the source for the clock. His source was telling him that if you clock off the video, there would be fewer problems synching up the genlock. I didn't get around to trying that theory out. mr bill

Oh, ok. Ron
