1. Main memory
Introduction:
SHARP and I/O data were the most recognized expansion card manufacturers.
Their product codes consist of two main parts:
1) The manufacturer:
- CZ - Genuine Sharp
- PIO - I/O data (older models)
- SH - I/O data (newer models)
2) The model number, which should be identical or very similar for both of them.
Question: What memory expansions are available for the X68000 ?
Answer: Each X68000 model is slightly different and here are the possible options for each one of them. The original X68000 and ACE/PRO models must have internal 1Mb expansion unit (Total: 2Mb) before they can be expanded further. The total amount of memory must be set by using SWITCH.X which can be found in HumanOS floppy.
X68000 | ACE/PRO | EXPERT/SUPER | XVI | Compact | X68030 | X68030 Compact | |
---|---|---|---|---|---|---|---|
CPU speed | 10 Mhz | 10 Mhz | 10 Mhz | 16 Mhz | 16 Mhz | 25 Mhz | 25 Mhz |

*CZ-5ME4 is an 4Mb RAM upgrade for CZ-5BE4 |
*TS-6BE16 requires Xe30 Xellent30 or CZ50 X68030 board and HIMEM.SYS to address above 12Mb |
2. Floppy disk
Question: How can I transfer image files from PC to real floppy disks ?
Answer: There are two different procedures. One for 5.25“ drives and the other one for 3.5” drives:
Question: How can I use different floppy disk formats ?
Answer: Download 9SCSET v3.14r4 and use 9SCDRV driver. Here is the list of supported formats:
- 0 - 2HS (9sec/trk 1440k)
- 1 - 2HD (8sec/trk 1232k) Standard X68000 format
- 2 - 2HDE (9sec/trk 1440k)
- 3 - 2HC (15sec/trk 1200k)
- 4 - 2HT (1599k)
- 5 - 2DD/9 (9sec/trk 720k)
- 6 - 2DD/8 (8sec/trk 640k)
- B - 2HQ (18sec/trk 1440k) IBM 1.44MB 2HD format
- Z - 2HDE98 (FDISK.SYS v0.98 compatible)
- 7 - Initialize FAT
- 8 - Initialize IPL
2. Hard Disk
Question: How can I connect a hard disk to my X68000 ?
Answer: All X68000 models can be equipped with a hard drive and the most modern approach is by using a SCSI to IDE/CF/SD adapter. The earlier X68000 models with SASI (SCSI1 predecessor) require SxSI driver in order to work. SCSI models require specifying boot device ID with SWITCH.X. Here is the list of SASI and SCSI models and links to tutorials:
SASI | SCSI |
---|---|
X68000 | SUPER |
ACE | XVI |
EXPERT | Compact |
EXPERT II | X68030 |
PRO | X68030 Compact |
PRO II |
4. Display
Question: What monitors are compatible with X68000 ?
Answer: The original X68000 monitor supports 15kHz/24kHz/31kHz display modes. 15kHz is used by TV's and 31kHz by PC monitors. The 24kHz mode is very rarely used and is not important. Approximately 80% of all software uses 31kHz mode, however some of the most desired games run in 15kHz. CRT monitor will provide you with the best possible picture quality. It is possible to use a LCD monitor with upscaler and scanline generator to make the picture look sharp as on CRT and not pixelated/blurred. However, be warned that LCD monitor and upscaler will introduce a small input lag. You have several options:
- Original X68000 monitor
- Microvitec M1438 which was very popular with Amiga enthusiasts and supports all X68000 display modes.
- NEC XM29 (24kHz not supported) or any other PVM CRT monitor which supports 15kHz and 31kHz modes.

5. Keyboard
Question: Which is the best keyboard and are there any alternatives ?
Answer: The classic pre-compact keyboards are bigger, and more durable.
