Hi! There is a SCSI-1 to IDE/CF and
SD adapter board to help fix this problem. It was a community project
over at vintage-computer.com forums. I have the PCBs and sent them off to
various builders but none are demonstrated working yet. Not sure what the
issue is although I suspect it is mostly just not enough time for the builders
to do the build and test to finish the board, demonstrate, etc. http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder¶m=MINI%20SCSI%20to%20IDE%20prototypes The bridge can convert SCSI-1 to and from
IDE and/or SD. You could use CF via an IDE adapter. I have one PCB left and keep hoping one of
the builders will be able to bring the project up with some initial
software. That would at least get the project started. Thanks and have a nice day! From:
n8vem...@googlegroups.com [mailto:n8vem...@googlegroups.com] On Behalf Of Douglas Goodall Regarding the SCSI-1 Adapter, I have been having a very difficult time
finding any SCSI-1 drives any more. I have been trying mostly on eBay, and here is what I have been encountering.
Drives are advertised as 40-pin SCSI drives, but after I buy them and they arrive, they turn out to be FAST SCSI or some form
of SCSI-2 that happens to have a 40-pin connector. I realize I could have asked more questions before buying, and not
ended up with a pile this high of 40-pin drives that are not SCSI-1, but that is my problem. Everyone else's problem is that the drives are just getting VERY rare
out there. On Jun 19, 2011, at 10:03 AM, Andrew Lynch wrote:
Hi! Mike and Douglas have been recently discussing a
new idea for an S-100 board. It would be a four port SPI board with space
for “mini-boards”. The mini-boards would have a standard SPI
interface and allow a variety of SPI chips to be used on small PCB. For
instance the ENC28J60 Ethernet adapter, SD cards, various memories, ADCs, DACs,
and a variety of other devices. http://www.mct.net/faq/spi.html Since John is already fully busy with S-100 8086 CPU board
and other projects, I’d like to attempt a new development approach.
Since Mike already has a design including a schematic, PCB layout, parts list,
etc, we could do a community build and test. Basically this would be we
take the existing design, gather up some funds, get some prototype boards, and
send them out for initial build and test. http://8bit.zapto.org/index.php/s100-cards-in-development/nic4-4-port-ethernet-card Although Mike’s SPI board would make a good starting point,
there are a variety of potential S-100 boards in the job queue we could make
this way. For instance, Mike has several other S-100 board designs.
Also Neil has a neat home brew S-100 serial, parallel, and memory board we
could make. The initial round of prototype boards will cost $150 for
five PCBs from www.33each.com which seems
to be a pretty good deal and make top quality prototype boards. Please post your thoughts, comments, questions, and
ideas. Thanks and have a nice day! |
