Hi Classic, Hope all's Well.

I'm not AM documentation, but my guess is; AM1200=0,1,2 are labeled on your pic as db9 (0,1,2); AM1203=db9 (3-10), and AM1213=0,1,2 db25 (3), db9 (4), db25 (5). Now if the AM1213 ports are like the AM1013 ports, there are also jumpers to configere the port's function. One of the first things I...

are you writing your VAM/L stuff to emulate at 8/10mhz, or as fast as the host will drive it, or both?

nope, 1.1A had it, I don't know about 1.0, I don't know what you're looking for but, is it possible it's a part of the z80 rom stuff, which I don't have?

As released by Alpha in 1.1A, looks like standard 68681 Duart stuff.

Well, I have three sets of schematics for three different revs of 1200's, and am not sure if that covers all 1200's, don't think we ever bought that rev. At least one schematic say the parallel port runs off a Z80>Z80PIO. What the first db25 port 4 or the 4th db9 port 4 does I have no clue...

I have no recollection of that configuration at all, I'll dig through the schematics.

I'm a dummy, I see it now! ..0...1....2 \9/ \9/ \9/ \?/ \?/ \??/ my ascii pic above line 1: Port numbers line 2: db pins I don't recall 6 built-in ports on the am1200 motherboard (I.E. the first line) I'm still confused about the last three ports on the first line. I'm pretty sure I have...

Oh, I'm a dummy, VFC has done to me also (compressing whitespace I think), and it didn't occur to me. Is the text graphic and jpg, a db0 pin out? If you are interested in the pinout, I believe port zero also has a remote reset, if that's what you're interested in, I can check the schematics. if...

My memory matches am1200 0-2, although, I'm confused by this [1]-[PP} and the 1203 0-3, is the am1213 a db25 4 port board???

Anyone know where I can buy a... 14 pin DIP IC test clip tool with 0.1" pin spacing? I had a stroke a while ago and I can't seem to logic probe pins and hit the reset button at the same time.

To my knowledge, the closest thing was SysXser Alpha's system diags.

Hey Mike, What is Tom Harte test suite?

I just wanted to update this thread, I’m now recommending the “Zulu” version of the same scsi2sd card, from the same place, the difference or advantage to the Zulu is no scsi2sd-util because it is built into firmware and runs automatically on power up, nothing to configure, plus to use it as a...

Classic, thanks for the update, they were after my time with Alpha, but i am looking for ward to Mike's emulator.
