Last post by yellow coffee - Today at 10:54:29 AM
Hi.
I have the np21w emulator, every copy of dos on FDIs, and a FreeBSD iso for pc-98. What do I do now? I have no idea, but I'm pretty sure this should be possible.

Quote from: Cyothevile on September 23, 2021, 01:48:43 AMWhat is critical is the file name or the computer won't detect HDD.

I will edit the post after I get HDD file name that I used. Very critical.

Ok I built my BlueSCSI and created a simple 1gb image file at a file called HD00_512.hda. I installed it internally in my Towns MFII via the empty caddy that came with it.

BlueSCSI seems to recognize the sd card as evidenced by the log file on the card, when I attempt to boot towns os from the cd or from floppy it starts to boot a HDD option light comes on and it crashes. If i play around with the terminator jumps and removing the terminator from my external SCSI port I can get it to boot without the HDD option light coming on but I cant access any drives (from SETUP2.EXE) to partition them.

Is the sector size not 512 and i need a different filename for it ? Different device number ?

thanks

Are you sure the positions of terminating resistors are correct? Because it seems like you cant even view the files.

Ok the external terminator is not the issue, it just changes whether I need to have the power molex connected to the BlueSCSI or not.

* If the power molex is connected and external terminator is not I get green HDD option and crash
* If the power molex is not connected and external terminator is connected I get green HDD option and crash
* If the power molex is not connected and external terminator is not I can boot but no drives are seen

I tried with a few different file names all with the same effect:
* HD00_512.hda
* HD01_512.hda
* HD10_512.hda
* HD20_512.hda
* HD30_512.hda
* HD40_512.hda

Once I got to device 5 HD50_512.hda no HDD option light and no devices. Which I guess is expected.

I  did have an SD card just not want to play with my bluescsi before and I had to try a different one and it worked.  It could be the same for your situation.  I tried a 64gb orange color Sandisk card and 400GB and they work very well.  The white 16gb one 'wasn't detected' by the bluescsi according to the LED blinking.  If you need some more help with bluescsi there is a discord server you can ask for help.

If you self-assembled the only thing that could be trouble is the position of your terminating resistors or the pins for micro SD slot. Otherwise I think it's the SD card.  This doesn't mean you need to light SD card on fire since winter is coming soon.  Just try a different one.  I wish there was a list of known-good models.


HD00_512.hda   is the file name I used to set it to SCSI drive 0.  Unrelated to Towns but I actually use that file name for using V4 image in X68000 computer too and it worked for my compact. 
Are you using for the X68000 the same file X68000_V4.HDS just renamed so the BlueSCSI can acquire the settings or did you have to do any extra processing?

Oh, good catch.
I'm also wondering about the bank checksums: the IDE patch does change a couple but my pc-98 doesn't complain. can you verify if my calcsum program output is identical to yours?

maybe someday i can update the patches

kamiboy, i still use your tool :)

both 5 and 3 inch drives have their upper magnetic-read-head assembly resting on the metal case with a one-sided support. i have gotten drives to work better by twisting the upper read head in the opposite direction, since they get torqued over time by sitting idly.

Quote from: fidelware on October 26, 2021, 04:26:50 PMHello everyone, I have won an FM Towns Fresh in Buyee, and I would like to update its PSU.  the project of the new pcb continues?

I wasn't able to find a pico that pushes enough power on the 5V line. Counterfeit pico worked but I can't honestly recommend.

What you can do is get a small flex atx and de-case it. Then go to GitHub page and load an Arduino pro micro with the firmware.

Cut the wires from dead power supply and basically match it to ATX. Trim the wires and match the correct voltage to the original stock wires. You need to use the BEEP maintenance manuals as a guide as it gives you the proper ones.

PS-on, OS-off, 5V standby, power on/off wires need to be soldered to pro micro. Then cover it in tape.

Be careful as I remember the 5V and 12V wires I think are both brown. You need to follow the scheme in the maintenance manuals that Hota-san scanned for me.

PM sent!

The "MIDI and 8MB card" looks awesome! Such a great idea to combine both upgrades into one expansion card!

@aje_fr responded mee couple of weeks ago and added me to queue on next patch of those 8MB+MIDI cards. So you should send him a message and wait few days. Still got no ETA about the next patch but I guess when there is enough people on the line he will make them!
