You need to do more than pings to test MacTCP. What TCP applications have you run on System 7.1?

Hello everyone!

Does anyone have an 18MHz or 12.5MHz XLerator they would be willing to sell?

Alternatively, a 16MHz XLerator that has been modified for 4 MB SIMMs.

thanks!!

I suspect the most likely place for someone to look for those instructions would be the ESProFile github: https://github.com/alexthecat123/ESProFile.

Yeah, if you attach your finalized version of the instructions here, I can put them in the repo!

Sounds great!

I want to run through it a few more times.

Second 200meg volume is working great.

Where would you want me to post the formatting instructions?

Excellent, good to hear you got it working.

Hello!

Why do the simple things seem so hard sometimes?

I have a good WORKING OS 7.5.5 that works just fine with TCP/IP but of course 7.5.5 is a memory hog

I made an OS 7.1 profile image, configured it the same, and it won't work.

I checked with the BlueSCSI docs, and I don't seem to be missing anything.

What I assume are the relevant settings:

MacTCP same settings (IP, subnetmask, DNS)
Wifi control panel: finds the wireless SSID on both 7.1 and 7.5 so I think they are both able to communicate with BlueSCSI
DynaPort driver installed.

The BlueSCSI documentation seems to indicate that the DynaPort will work with 7.1 even though it does not have OpenTransport.

TESTS:

System 7.5
Ping from external host (after launching browser, or MacTCP Ping which is interesting)
Pings out
Browser works


System 7.1
No ping out to internet or local host
No ping from local host

Any suggestions?

the fact 7.5 does not respond to pings until a TCP app is launched makes me wonder if it is a driver issue?

Second 200meg volume is working great.

Where would you want me to post the formatting instructions?

I made and formatted a 200meg image today and had almost the same issue.

MW+II installer saw the External Profile and started the init of the raw blank file but I knew something was up because the green LED on the external profile just blinked in a steady pattern. After 3 hrs I gave up started the process again and this time I changed SD cards and the format worked fine.

The MacWorks initialize procedure involves writing to every sector on the volume, so 3 hours of consistent blinking may be normal for a 200 MB volume -- it may have been proceeding correctly. Or maybe not; tabulating some statistics on how long it takes to initialize various sizes of volumes using various emulators on various ports would be useful.

If it initialized quickly using the sleight-of-hand "swap the SD card without the OS knowing" technique, I wonder if the target initialized to the size of the volume on the first SD card rather than the second. Examine the size of the resulting volume after restarting to confirm.

I suppose there is also a possibility that the one SD card is functional but encountering particularly slow writes due to some defect.

Well, labeling the drive cage as 'processor_x' is ridiculous!

I do believe that an organization calling itself a museum should hold itself to a reasonable standard of accuracy.

I have been restoring antique motorcycles since I was 14 years old.

I cringe when I visit the Barber Museum because many of the bikes they have there that I know very well are incorrectly described on the display and often incorrectly restored.

So I really get it.

As a devil's advocate, I also helped run a volunteer organization for over a decade, and sometimes you have to work with what you have.

I feel that if you have knowledge that can help a museum, volunteering and being a good volunteer are two of the best ways to mitigate these issues.

My 2 cents on your 2 cents! 
 

But it may mostly work in this particular case, assuming that the installer re-reads the size of the drive after you swapped SD cards, and expecting it to crash after it is done, since it cannot read the System, Finder, etc. files.

Or perhaps it is the case that no files were opened from the SD card because the System was booted from your SCSI drive. If that's the case, then there is a mystery why the external parallel drive did not show up with the newly created file (requiring you to boot with another SD card installed). Perhaps the ESProFile documentation mentions required specifics regarding file attributes or something like that, or perhaps there is a newer version of its firmware?

Yes, I have 2 ESProfiles (one internal one external) plus the BlueSCSI. MW starts from the internal and boots to the SCSI.

So I made and formatted a 200meg image today and had almost the same issue.

This seems very odd to me.

I will try another run at it tomorrow.
