I'm fully aware of that, in fact I plan to try using a 4GB CF card on my 4000/60 at some stage to see what it does. You linked to a *SATA* to SCSI adapter intended for use on hard drives?
I'm aware that SATA to CF/SD adapters are available, I used one for a while with a CF card. That may be an option but like others have said the reliability can be variable. Also some companies that offer embedded micro-PC stuff also sell 8GB and 16GB SATA SSDs that might be an option too, maybe? I am fairly sure I have a 16GB one spare somewhere.
On a Mac you can lay down partitions on the disk, the limit on a Mac IIRC is on partition size on the the early SCSI machines, not on the drive size (which I think is 2GB or 4GB on those due to limitations on the SCSI chip?). I am not aware of any way to make DEC software do that.

Thanks for the link Daniel. This is great news. I know that there have been various incarnations of adapters that have come and gone and been niche enough that there hasn't been reliable evidence of their functionality computers with older scsi implementations. Typically they are built to support equipment in the music industry.
Anything that provides us a way forward is definitely a good thing! I don't like noisy hard drives any more than the next person.
I will have to explore my theory of the 18GB limit on the VAXstation 4000/60 and /90 and I thought that was a hard rule, but I'm happy to be proved wrong. It may be that I was using an earlier version of VMS where it definitely is the case that only certain models of drive are supported. I had to root around to find a supported drive for OpenVMS 6.1 - even generic Seagate 50 pin SCSI 2.1GB drives weren't recognised because they aren't RZ* tagged in the firmware.
Regards, Mark.

I think it is about as fast as possible, but it might be more memory efficient.
On my machine with firefox, the images are drawn about instantly.

I wonder if we could turn this into a SIXEL decoding plugin for websites somehow..
So you could have a whole bunch of SIXEL images on a website, an INDEX.HTML that imports this javascript and then displays the images?
Because I haven't found any utilities to convert images FROM sixel to other formats, just one to convert netpbm -> sixel.

to Javascript and combined it with Flot and a JQuery terminal:
http://rullf2.xs4all.nl/sg/sg.html
You then get a Javascript terminal, with a display function; some examples:

and
js> display(digital$)
Considering the run time to display the latter image, photos should

Cool - any change you could add my logo (B&W picture of angry monkey from Family Guy)?
That would totally make my day.
There are plenty of CF or SD cards under 18gb. Also, there must be some way of only using part of a drive, as these cards are used extensively in old Macs which have a 170mb boot drive limit.

Which is great, but again you run in to the snag that I've never seen a SATA disk smaller than 40GB and the upper size limit on a VAXstation is typically 18GB. Somewhat problematic.

Quite so, the Gigaswitch FDDI is large. The measurements are: 35.25" x
19.95" x 19.50" and the weight is 192lbs. The power consuption is
about 1000W depending on the amount of line cards.
There are FDDI fiber and twisted pair line cards and 100BaseT line cards.
Many operators used to have those at the time and the later ATM
versions as well.

This sounds like it might be the right solution for me?

VNswitch900FX, FDDI/FE swt 1 FDDI and 2 FE port switch.
Yes, that would be the one when converting between FDDI and 100BaseT Ethernet.
The best effort it can produce is about what 100BaseT can, because it is the lowest common nominator. FDDI performs better due to the larger packet size (which is usable only between FDDI nodes) and the lower overhead.
Btw. Many of the FDDI principles was used when developing FibreChannel.

Yeah.
It's unfortunate, really. :(]
Yeah. :(
Sounds like a business opportunity, basically build an enclosure, get 5-6 consumer SSDs, RAID6 them, expose a SCSI/SAS/eSATA interface to the host. If one of the drives breaks/runs out of write cycles, the box indicates the slot and we provide a new SSD for the slot.
