I've heard that Adaptec make a controller to > go to SCSI; what's its number, and where (pref. UK) can I get it OK, here is the deal. You need a host adpater. Which is a DMA port to controler. I would recomend the ICD adapter. I just bought it and it seems to work well. (Problem is that it was version 2.7 and i know for a fact that software version 3.2 is out.) It was priced at $123 US. It is suppose to run with either a controler board (the adaptec you mentioned) or a embedded SCSI device (which you said it is). If you are in dought as to wither it is truely an embedded SCSI, check for the 50 pin plug. If it is there, the controler is built in, if not, you need a adaptec 4000a (repeat 4000a) controler for standard format. If your drive is RLL rated (an extended format) you need an RLL adaptec controler 4070. Finialy, if you cant get it to work, sell it to me for an absurdly low price. > (how much?).

The ICD adapter can handle 7 devices. Device 6 is a built in clock. That leaves 6 drive spaces free. Also, you can buy controlers that control two drives for the price of one device. (You can have up to 12 hard drives.) > > Thanks in advance.

PS: I forgot to tell you, Tos 1.2 can only handle 16 megs at a time. You have to give you drive imaginary particions to access the full drive. EX: You have 50 megs, you make it think of 5 10 meg drives. (Tos 1.4 can handle 32 megs.) (It is covered in the ICD manual if you are confused.) Stuart (How's the weather up there? A nice hot 75F ? Snicker! :-) (I'm sitting here at 1 AM and it is 85 outside! Too hot for me!)

Host adapters for the Atari is a touchy subject..... Some of the later embedded SCSI drives are too fast for older host adapters. In gereral I have tested quite a few drives and found that Supra (08) series is the most compatable, it will handle just about every HD and SCSI type available. Older versions of Supra are incompatable with faster embedded SCSI drives. ICD will handle most of the HD's on the market but I was unsucessfull at getting faster Maxtor 8000 series to work properly. But in general , they are my second choice. Both the Atari and Berkley systems work with slower controllers like teh Adaptec and OMTI but they work poorly with faster type embedded SCSI drives! In general Atari SH204 works fine with teh supplied HD, but if you plan on adding a second drive....WATCH OUT! --- * Via ProDoor 3.0R

The BMS-200 has replaced it and has a 1.6 Megabyte/second sustained data rate. One CDC Wren SCSI drive that a customer brought by had a transfer rate of about 700+ Kbytes/s. Both the Atari's host adapter used in the SH204 and ICD's host adapter transfer data at about the same rate.
