Strange SCSI board

[famiac]

hey guys, i'm not exactly sure what this board is/does. I found it inside my x68k when i bought it.

I think it might be a Mach 2 SCSI host but looks like there's RAM in there?

Can someone help me out?
Here's a photo:

I think there were some mach 2 boards that also had ram.

How do i check how much is on here?

How do i check how much is on here?

Looks up the chips on the ram and see how much 1 is and then multiple that by how many there is on the ram (front and back).

 Hi Famiac !

There are 16 pieces of MT4C400 1 MEG x 4 BIT DRAM chips. A pair of two chips form 8 BIT, which is required by X68000, and it looks like the SIMM module has 8MB capacity.

Keep the scene alive !

Oh wow so this doubles as an 8MB ram board?

I'll test it out. It'll be for sale soon.

Is there any particular advantage to the Mach 2 boards?

I think they support faster data rates.  So later scsi devices might work better.

I'm not sure if those boards need a particular driver installed before they'll work.  One of these other guys should know.

I know you have never seen the real thing, the type where there is a parallel port to "Mach-2" expansion board should did not. Is there until "Mach-2p" of SCSI + memory slot, but, what with a further parallel port had never heard before.

Where it was examined, seems to conform to the configuration of Tsukumo Denki (九十九電機) made of "TS-6BS1mkII '(mk2 dash)" s product called the SCSI + memory slot + parallel port.

In the past the log of 2ch.net of Japan, I found the writing applicable, please refer to.

By the way, because "Mach-2" s and a SCSI-2 expansion board has the advantage for the data transfer rate. But "TS-6BS1mkII '(mk2 dash)" will think that there is no advantage of the data transfer rate because the supposed expansion boards of SCSI-1.

Thanks for the info!

What could one gain, besides ram, with this board that one could not gain using the sxsi driver

[rano_yuki]

SxSI?
Because SxSI is a driver for using a SCSI device in the SASI port only X68000, but you should not need this time to use?
Since the function of the corresponding SCSI-BIOS referred to in the PC to the SCSI expansion board itself is built, you should be able to directly recognize if SCSI-HDD.

In order to ascertain whether the SCSI expansion board has been recognized properly in X68000, please use the software called AskSCSI.

In addition, if you use the MO and the CD-ROM, please use the driver called SUSIE.

That's not what i was asking, however that is still very useful information. Thank you!
