it looks like the HxC2001/Gotek usage is limited on Nabu. You can make HFE images from flux on PC and it will keep the DPT on track0 but looks like fluxing an image direct to the HxC2001 the drive will not store the DPT, so you cannot format or make new disks only using the HxC :/

I use the hxc to import the img to set a compatible GAP3. But maybe i can use gw directly. I just need to figure out how to set the gap there

for a 5.25 360KB the process would be: dd if=/dev/zero ibs=5K count=80 | tr "\0" "\345" >> new_nab2.dsk diskdef nab2 seclen 1024 tracks 80 sectrk 5 blocksize 1024 maxdir 192 skew 2 boottrk 1 os 3 end

Well I just built my FDC replica and made my very own CPM bootable floppies with the help of greazeweazle and cpm tools. You can get the HFE and use with HxC2001 or image it to real floppies using the gw or kryoflux. These are the 3.5" with my white over black CP/M, Turbo Pascal and WordStar. I...

I found a bug on Cloud CP/M. I made a small program like LOAD.COM that will load a file like LOAD.COM FILE.BIN. Using mame and the original CP/M floppies there are no problems running from drive A or B. But on cloud cp/m the FCB fails. I am using the original FCB that CP/M creates for you as...

where can we get these boards ?

Do we have the BASIC manual ? We could make a basic program that use OPEN commands and write long files on it too.

So if you write a long basic program and save it as ASCII ? SAVE "PROGRAM.BAS",A ? That would make easier to understand the sector logic. Just bunch of REM's would do it since they are numbered like: 10 REM / 20 REM / 30 REM... The sectors are 128 bytes but we don't know the block size. Don't...

Well as soon the floppy board replica is proven to work we can all build our own and try ourselves.

Do these drives have a DS selection jumpers ? Still shuggart are different than PC driver this is the reason PC drives deal with twisted cables for drive / head selection. A good test would try to replicate your working BASIC disk to a second one using the PC. Also imaging the 41 entries disk...

One interesting test: try creating more than 32 files. See how the directory goes on BASIC NABU. Someone has reported the nabu images had weird 32 entries only.

Second we are assuming the disk geometry for the BASIC NABU 4K is the same for the CP/M NABU Dev 8K. They could be different (made by different teams how knows ?)

But the drives are shuggart right ? How can you use them unmodified on the PC ? Wasn't the hard setting for the head / side ?

Does the NABU BASIC have a FILES command ? If you insert the CP/M disk on it and try to list its contents ? Of course I would advise to try to work with a copy or at least a write protected disk.

It was pretty easy to install a gotek flash floppy on my Toshiba 1200 using these 26 to 34 pin adapters from ebay: You just have to set it to shuggart and set DS1 as the adapter wires drive select to DS1. I saw other threads were some people had trouble adapting pc drives to it the thing is...

Hi, I am struggling to find images from original Toshiba 1200 disks, the ones that came with a brand new toshiba 1200. Does anyone here have these ? Thanks,

I was looking for which *NIX flavour would work on a 5150 with XTIDE it turns out MINIX works flawless. All the others direct access the HDD controller like SCO Xenix and PC/IX. And installing MINIX on the CF card it is the best part All you need is the POSIX dd command for that either on...

I found this auction on ebay, a strange monochrome card, although I don't intend buy another monochrome card this one seems little odd: 2 strange features: only 2K as SRAM and a cinch connector. How come it has only 2K? would this board lack attributes ? Or, due to the cinch connector it only...

Is there any copy available ? I can only find old as 2.26. The installation manual from version 3.0 states you need at least a 40 column wide CRT monitor but any resolution below 64 gives me an error at start. The reason for that I am looking for a version that works in 40 column to run on C64...
