  1. Also, run disinfectant to make sure you don’t have any viruses. My mac plus was infected from software from mac garden, and was very slow.
  2. Hello all, I hope the following tutorial will be helpful to those that use a scsi2sd device. I know it has been useful to me. Up until now, in order to transfer a file to my physical mac, I had to: a) dd contents from my scsi2sd card over to my machine b) strip the raw partition file (2 partitions) c) update files with mini vmac d) combine .dsk contents to single file and write to sd What I have achieved is: a) Put sd card in PC b) Use softmac to read/write/boot directly from SD and mount it as if it is an actual scsi drive
  3. Many thanks. Awesome work although I cannot get 5.1 surround working on my Mac Plus Just kidding... I am able to get around 10 frames/sec in both sd and hd. I think the bottleneck in my setup is the scsi2sd. Its activity led is constantly on. I have tried with both 6.0.8 and 7.5.5 with same results. Does anyone know if playing with scsi2sd settings can increase read/write performace? Thanks
  4. I just wanted to say congratulations to the community. I personally to not recall the game, but then again I did not have internet when I was a Mac user. Great achievement nevertheless.
  5. Just in case anyone is interested, I have dumped the contents of the 128Kbit eprom (attached) and I am trying to see how it relates to the factory rom. dump.bin
  6. Make sure you tape the hole if the disk is hd. also, i. The beginning i also had same issues like you, then I cleaned the heads of the floppy, and steadily the bad sector problem started to go away
  7. @erichelgeson The label on it says Sony, model: MPF820-E. I pulled it off of an old computer. do you get an error? Do you have problem reading or writing?
  8. It is the same command as 1.44MB disks. I think it reads the right format from the diskcopy header. The command is fluxengine write mac -i mac.diskcopy and relevant information can be found here http://cowlark.com/fluxengine/doc/disk-macintosh.html
  9. Sorry I meant a Mac floppy drive operating in an actual Mac!
  10. That's great. I hope you get good results. I found that the Mac drive is better at reading. E.g. when reading some disks with this setup I might get a few bad sectors, whereas the Mac drive can make an image just fine. But nevertheless it gives more choices which is great.
  11. Hello all, Do you believe it is ok to use a normal AA battery in the macintosh plus? I heard and verified that it works, even though the factory one is 4,5V. Do you think there is a downside, other that longevity? Thanks
  12. Sorry I should have mentioned it is dd for windows, and the command is executed without errors (it says 1024+0 records in/out which is as expected for a 1gb image). Maybe it is a bug of dd for windows.
  13. Hello all, I have been using scsi2sd and mini vmac and transferring images back and forth. I think I am doing something wrong with writing sd can using dd, because the mac will not boot. When I write the same image file to the same sd card with balena etcher, it works fine. Could you please tell me if you see something wrong with the following command? Thanks in advance dd if=image of=\\.\Volume{......} bs=1M
  14. I really can't understand why someone could go into all that trouble just to patch one or two bytes. Looking at the source code: https://www.bigmessowires.com/rom-adapter/plus-rom-listing.asm , it doesn't even seem to be executable code at that address. It looks more like a table of characters. I believe that the pcb: a) Was installed by the greek apple distributor, in order to fix some kind of greek bug or b) was installed as part of some anti-privacy mechanism for specialised software (kind of like an old school usb-dongle) Could it be that the m
  15. Actually that makes a lot of sense. The two differences add up to 0. (0x88+0x88-0x8E-0x82 = 0) So I guess the only thing left is to figure out what is special about rom offsets 0xfbc9, 0xfc3b
