+--- Thread: Replacing B drive with Gotek (/thread-418.html)
RE: Replacing B drive with Gotek - ChickenMan - 11-05-2022
The Gotek's dont seam to be seen when you first turn on the 'bee so use RESET and it should boot. I assume the disk image has a system track and bootable ? What system have you put on the disk image ?
As with ubee512, copy your dsk image file to the disks folder then just use
ubee512 -a filename.dsk changing filename to whatever your called it
RE: Replacing B drive with Gotek - mjelic - 11-05-2022
Well, I must be doing something wrong...
Even after I reset the machine a few times, still just sits at the blank square. (I can hit M and it goes to the disk monitor, but I have no idea what to do in that. I can't list files or do a DIR or anything. More research needed.)
On the Gotek, I have a USB that has a dozen files on it. Have tried to rotate the knob to display the following then hit the Reset button for 5 secs:
128k_premium_getting_to_know_your_microbee_ds40.dsk
128k_premium_master_ds40.dsk
edasm_v42_ds40.dsk
Now I have no idea if they are "bootable" disks or not... But they all work fine in the Windows emulator. I'm at a loss.
Could it be that my Gotek is configure to be B drive? Does the Bee boot off B: if A: is empty? BTW, I have my Gotek on the left and standard floppy on the right. Since the floppies were RIVETED in (who the hell though that was a good idea??) I didn't undo both of them, just the left one.
RE: Replacing B drive with Gotek - ChickenMan - 11-05-2022
Firstly, the EDASM_v42 disk is NOT bootable while both the 128k_premium disks are.
I also assume the USB key is FAT32 formatted, anything else will NOT work.
Also, are you running the BN60 boot rom in your bee or the original BN56 ?
If the Gotek has the jumper set at S0 then its setup to work as A: drive and you are using the original 34 way floppy cable and just replacing the left 5.25" A: drive with the Gotek using an adapter from 5.25" floppy to 3.5" floppy or your using a home made cable? Can you unplug the Gotek and change the B: jumper to be A: and then does it work ?
RE: Replacing B drive with Gotek - mjelic - 11-05-2022
Hey Chickenman,
The USB stick was in fact just FAT, not FAT32... And it didn't make a difference when I reformatted it. I didn't expect it to, because as long as the GOTEK can read the USB, then the file format shouldn't matter. But anyway, it's now FAT32.
I think the problem is that no, I'm not running BN60... I came with a BN56. I have an eprom burner so as long as I can find the image, I can burn myself a copy. What did it have in it that was needed to make worth with Goteks?
I'm loathe to pull the disk box apart for the fifth time to see what the jumpers are, but I'm prettu sure the Gotek is S0, and I'm using the standard ribbon cable that was in the drive box. They are nothing but simple straight through connections.
RE: Replacing B drive with Gotek - ChickenMan - 11-05-2022
Nothing in BN60 thats specifically needed by the Gotek, it just has a built in Self Test so stick with your BN56 until all is working.
The Gotek cant plug into the existing floppy cable as a 5.25" floppy and Goteck has different connectors. So how are you connecting the Gotek?
RE: Replacing B drive with Gotek - mjelic - 11-05-2022
My drives are the 3.5" ones. The ribbon cable is a flat 34 way cable that has two IDC connectors closer to one end and then a long bit of cable and a single IDC to plug into the Bee. Can't remember which position the drives are on the cable (was Gotek last or the right hand 3.5", not sure) but I figured there isn't a twist in the cable like I've seen in other systems so it wouldn't matter?
RE: Replacing B drive with Gotek - Ernest - 12-05-2022
I know this maybe a really obvious question but I assume the system is working on a normal floppy OK?
If not you may have a hardware issue with your Coreboard I.E. the WD2793 preventing the FDD of any type functioning.
Is this a Premium system if not then the BN60 is not suitable.

Arr okay, then DONT try booting DS40 (5.35") images, suggest to try booting 128k_premium_master_86_07_ss80.dsk image.

1) I don't actually have any 3.5" floppies on hand (but that's a relatively easy fix)
2) If I did have one on hand, other than the Bee, I don't have anything else to put it in to try and format it in any way.
Yes it is a Premium 128k. I'm sure the images are easy enough to find in the Repo, but are the Assembler listings (with comments would be nice) of the ROMs available anywhere?

Ah, OK... Which brings me to ask, what are all these numbers supposed to represent:
ds40 (I'm guessing its 5.25" floppy)
ds80
ds82
ds84
ss80
Didn't make a difference, though... So I think I'll pull the box apart again and see if I can make it work with the 3.5" drive I've already de-rivetted and can see what the jumpers are set to it and it's easy to access the Gotek jumpers even when screwed in place. I'm thinking that somehow the right hand 3.5" drive (still rivetted in place and can't see jumpers) might be configured as Drive A: ? I'm assuming the Bee only boots from the first drive and doesn't cycle through all drives looking for a bootable disk?
RE: Replacing B drive with Gotek - ChickenMan - 12-05-2022
I can send you a pack of 10 3.5" floppies if you wish, I have a few spare here
PM me.ds40 = Double Sided 40 track as used in all original Microbee 5.25" floppies
ds80 = Double Sided 80 track 3.5" format used in Premium 128k & 256TC
ss80 = Single Sided 80 track 3.5" format used in CIAB, Prem 128k and 256TC
ds82 = Double sided 80 track 5.25" or 3.5" as used by Dreamdisk, dont use these.
ds84 = Double sided 80 track 5.25" or 3.5" Peter Broughton system
Out of the factory, the left drive is set as A: and the right as B: but you never know what the previous owner has done. I would never screw it all back together until I have it working, saves a lot of pulling it apart again
Yes the bee will only look at A: when you turn it on. The 256TC has an option though to boot from B: if there is no disk in A:
