Has anyone tried these on their Amiga?
It seems to be a acard style arc chip like the acard aec-7720U or similar scsi to ide bridge uses.
since CF is basically a ide bus, it seems logical.

Is there a project page floating around somewhere for these?
-
Wouldnt scsi to microsd be a better choice?
- Its well tested to work on amigas (read the reviews from the link below).
- microSD cards are usually much cheaper than CF cards
- The scsi2SD adapter is a bit cheaper than that scsi2CF adapter.

SD is serial protocol needing more chips for translation,while CF is basically ide and direct straight wired . since this is a scsi to ide bridge it will be fast, prob. nearing 10MB/s depending on the ssi controller, unlike sd solutions which are very slow.
seems to be this guy doing them:

This is true. I will say you might be pleasantly surprised if you give the SCSI2SD a try. I have several and for old narrow devices they work quite well... including me ol' Miggy.

i use the PCD50 and 60 scis card readers.

They are nice. But slow. I have a CF Monster in my A500/A590 and it is twice as fast as the SCSI2SD. (bought 6 months ago) The SD handles greater capacity, but the Monster is faster. I am guessing these ones are akin to the monster. But how much capacity you can carve out is a question.
-
Is the CF Monster the same as the Aztec Monster, or is it another product from the same developer? I got an Aztec Monster to put in my 4000T, but the thing is incredibly unstable and effectively useless. Planning on replacing it with a SCSI2SD, but if there are faster (stable!) options available I might go for one of those instead.
-
Has anyone bought one of these yet and tried it out?
I have the SCSI2SD (both 6 and 5) and they're OK, but, the fastest I can get out of them is 1.8mb/sec, even on my Blizzard 2060's SCSI controller.
-
I have one and wish I had another, it works great. I plugged it in to the GVP 68040 card scsi to cf and bingo. I had already built the cf card on a scsi to IDE converter card I have. Every thing works,I don,t have a tool to measure transfer rates.

Sysinfo has a rough estimate for speed, if you have that installed, in the drives section.

Yes, it is the Aztec Monster. Sorry. Mine works flawlessly (now) on an A500/A590 but I did have a heap of trouble and could not get it to work with CF Cards over 2GB. Even when configured and set up on my 1200. I found additional partitions above 2GB were being clobbered. Regardless of number. After lots of logical troubleshooting I got it stable with one 2.1gb partition. I hasn't failed me since then. I got in contact with the Japanese supplier. Who was generally good BTW. He was sure it wasn't the card. But I didn't have this issue with the previous SCSI CF module.

Yep same here. On a lowly A590. Tells you where the bottleneck is.

The v5 is probably doing the best it can. Same with any SCSI controller that only supports the Async SCSI spec, which (theoretically) tops at 2.5MB/sec.
The v6 supports sync, and needs a few things:
- The SCSI2SD, if the setup tool gives you you the option, must allow for Sync
- The boot block needs to have the Sync flag set on the partition(s) you define on the Amiga. Typically it will be unset, meaning Async bus communications (speeds) by default.
- Check your Blizzard SCSI docs to see if there is anything else that needs to be set to allow for Sync SCSI.
- Double check your SCSI termination is correct. That's termination at both physical ends, and never in the middle. If it's off, you risk errors when it tries to transfer data.
Also, make sure you have the latest v6 firmware. It's still looks like a work in progress, but I saw ~2.7MB/sec on GVP Series II stock 68K machine on an A500 with GuruROM (omniscsi.device), vs 2.2MB/sec with both v5 and v6 in Async mode (and same Async speeds with FastROM v3/v4).
-
From where does this SCSI2CF card come? I'd like to see some more specs on it. The SCSI2SD allows you to partition the card into multiple devices, handy for computers like the TI which are limited on drive size (around 256MB) so I'd like to see if this can do the same.

Thanks for that info. I need a larger drive than that for the 4000T, so it looks like that machine will be getting a SCSI2SD. I'll try to repurpose the Aztec Monster for my GVP A530. I only need a gig or two for the 500.

I think it uses same firmware as a real acard, you might try and drop it back to earlier acard firmwares.

@mechy
You may want to check out the following thread
http://www.amiga.org/forums/showthread.php?t=72226&highlight=scsi2sd
Acill discusses some useful info about the bridge chip the different versions of the 772X use. From the thread he seems to like the "correct" ones.
Nothing is quite as good as those Mechy Card readers :) I bought three from you.

Any idea how that is done? Is it over the SCSI bus, or is there another interface that can be used to reflash the firmware? I don't have any SCSI-capable PCs at the moment.
On a different note, I just had a look at my AztecMonster card - it uses the same ACHIP ARC760-B chip as the new board linked at the top of this thread.

OK, I have model # PCD-50B & Mike has PCD-60B. Here's a pic of of the 50B.

Here's someone still selling the PCD-50B on eBay...

Occasionally they still come up on ebay, in the $200+ range. :(

These pictures are kind of old, but here you go.
I still need to fix that issue of the A500 - once I stuck a Guru-ROM in there, the PCB raises the case too high to close properly. Will get around to fixing that one of these days. ;)

I flashed it under a xp pc.. using a adaptec 2940uw(can be had on ebay for $5~).
u can find the tools and flash on acards site. get the utility and the firmware file.
Try dropping back to a firmware earlier than 3.89. seems acard did some stuff to the newer firmwares that amigas didnt like.
http://www.acard.com/english/fc0101.jsp?prodno=AEC-7720U
mind you i have never used the aztec monster but it appears to just be cf slot integrated to a acard 7720U adapter. if memory serves i ended up with 3.86 on my bridges. try all this at your own risk,but i dont see anything that can go bad.
Aztec monster guy seems to lean toward macs and i bet he has the mac firmware in it.

Anyone looking for a pcd-25B scsi card reader?
2 slots(use pcmcia to cf,sd whatever adapters),uses 2 scsi ID's,no luns.. great for older amigas with stuff like 2091,gvp,etc:

i have no affiliation with this, just saw it on ebay btw.
not to gum up this thread... but has anyone tried these mcdisk-2?:

I have an A500 with almost the same exact configuration. A500, A500 HD8+, VXL 030, VXL RAM32, mechreader 50B version.

Noice! :hammer:
I don't get to use mine as often as I'd like, but recently have been getting my gf interested in a few games (so maybe if we use it together, we can use it more often).
Here's a picture of teaching her how to play "The Chaos Engine" last night. :lol:

Not mystical at all, i sold them here for 3-4 years:
https://web.archive.org/web/20130924003304/http://a4000t.com:80/store/index.php?main_page=index&cPath=68
Sold roughly 2000 card readers in a few years. sadly very few amiga people bought them,it was mostly sampler users oveseas. i actually sold them cheaper than going prices then.
the pcd-25B (2 slots,mounts as 2 scsi id#'s)not listed there but i had only a few for sale early on.
the pcd-47b was a 3 slot model, it uses 3 scsi ID#'s one for each slot.
the pcd-50b is a 5 slot model, it uses LUNS for all but the pcmcia slot which is lun0 technically.
there are quite a few other models that are more uncommon, PCD-15,PCD17,
same with the pcd-60b, its a 6 slot model,works same as the pcd-50b with LUNS
You could use a pcmcia to cf adaper in the pcmcia slots. All slots bootable if the scsi controller allows.

And a great service you provided too Mechy. Much appreciated.

I said mystical...not mythical :) I've never seen one, and those who have them speak well of them, but, I had never seen one. Wish you were still selling miggy stuff....

Looking at this picture again, it appears that this card may be too wide to fit in the space of a standard 3.5" drive - unless you rotate it 90 degrees, anyway. :(

So, has anyone bought and tried one out yet?

I was tempted but it looks to wide to fit in a 3.5" space, and I don't want to have something all jacked up and turned sideways just to fit. ;)
Also, who am I kidding? I'd get the thing and it would sit on a shelf for a year before I had time for it. :(

+1.5

I asked the seller and it measures 122mm x 79mm, so, yes, it is wider than the 3.5" bay.

That's too bad,it sure makes it a deal breaker for anything i would want to use it on.

So, I bought one to try on my CS MK2 w/ CyberScsi module on my A4000. No Joy. I took the CF card that I am booting the A4000 from (on a Fast ATA MK VII), and put it in the SCSI-CF adapter. Set the terminator on and the SCSI ID via its jumpers. Tried all three possible IDs that it offers, turned termination on and off, set term power on and off, and, nothing but the Kickstart screen appears, asking for a disk. The card's LEDs illuminate, indicating it's getting power, and the read/write LED on the card will flicker for a second or two, indicating the SCSI module is trying to access it, but, it won't boot. I've tried 4,16,32 GB Sandisk CFs and a 4GB Kingston, all of which are system drives on other Amigas I own, but, nothing boots.
If I should boot the A4000 from the Fast ATA, while having a CF card on the SCSI-CF adapter card, I can open up HDToolbox in 3.9. I can indeed select it, it shows up as SCSI-IDE-Bridge, or something similar, but, when I click on it to view the partition tables on the CF card, I get an error stating that HDToolbox cannot be used on this type of drive (or something similar to what one gets if you try to select a SCSI CDROM drive with HDtoolbox).
-
I have one and wish I had another, it works great. I plugged it in to the GVP 68040 card scsi to cf and bingo. I had already built the cf card on a scsi to IDE converter card I have. Every thing works,I don,t have a tool to measure transfer rates.
Did you have to do anything in particular to get the card to work?
-
After a few more CF card tries and some back and forth with the seller, I could only get a 10+ year old Hitachi 32 MB card to work. The seller says that he has had problems with the adapter being picky about CF cards and, usually only working with smaller cards. He offered a return, which I will be taking him up on. He called CF an outdated technology fraught with problems, and said he will be redesigning the card in the near future to use SD cards. Also, instead of needing to write an EEPROM to update or change the firmware, via an eeprom programmer, he will be implementing direct control via a micro-usb to the card, much like the SCSI2SD card, for firmware updates. I wanted to like this card, but, it just doesn't work well in its current form for a Amigas. Speed was between 3 & 3.5mb/sec on a CyberScsi module on my CSMK2 060/Amiga 4000.
