Hi, I don't have my attempts with the Kaypro 484 with the TurboRom 3.4 and Turbo-Bios as well as a German keyboard (QUERTZ) as I would like. Char-Rom is 81-278A or the original 81-278. 1st boat Message: 63.00 CP-M - TURBO BIOS 1st boat TurboRom works without Turbo-Bios (QWERTZ) Message...

Thanks for the info. Yes, that's right, I have two Kaypro 484 OK, the predecessors need this option. PIN 2 is connected!

When using 28C64 or 27C64 in the Kaypro 484 I find the connection after durgadas311 description via NC, WE, VCC to RDC and A12. PIN 26,27,28 -->1,2. Why A12. I'm not connected to A12 and it's been working fine for a number of years. Could it be that the PIN otherwise remains open and can cause...

Hi, I can remember that before I switched to two Gotek drives, I made the system trace with sysgen from the floppy drive. Kurt https://retrocmp.de/kaypro/kay-p2_hrdw.htm#mb-2X

Hi, I have a bootable file (boot.zip) for Kaypro 484 with FF.CFG Posted. The file was created with diskdefs kay2 or kpiv made. If these two files on the FAT32 or FAT16 formatted stitch is saved and nothing else it must work. Try it as described Which Kaypro do you actually have. Can your...

Hi, can you upload an example of how i did it. I am testing with my Kaypro 4/84. Maybe we can fix the problem. Kurt

Hi, try this. Format Fat32. Copy FF.CFG and hb75d_forum.dsk into the main directory. Should boot. Was SYSGEN made for those applications? greeting Kurt

I just saw that SANDISK also works on Windows. As written - no idea. I'm a Linux user for things like that. Kurt

Hello Tommar, I already pointed out a link to the Kaypro 4/84 conversion with Gotek in thread #12. You have to translate the texts there into English. Here the link again http://www.forumcpm.gaby.de/viewtopic.php?t=50 The operating system on your computer must be Linux. It may also work with...

Hello Tommar, Getting software onto your SD is relatively easy. The SD is created in FAT32 format. A TEXT file - FF.CFG is copied to the SD. In addition, files with the extension DSK are copied to the stick. The CPM files can be copied into the FILE A.DSK. With a special program, the cpm...

Hello Tommar, as long as you try to copy your disks with the Kaypro and as I read the LW does not work properly there are problems. I struggled (it was 2017) with this problem for 2 days. A friend had a CPM calculator and he was able to make copies for me. Later I just swapped the drives. A...

Hello Tommar, if you want to go on a CPM journey of discovery with an old computer like the Kaypro, then I recommend two options: 1st option. You or someone else install a Gotek LW instead of the Disk LW. Why? The LW or the floppy disks simply wear out after 35-40 years. I have various Epson...
