3185.0. "Help (yes with Hard disks again!)" by AYOV28::ATHOMSON (C'mon, git aff! /The Kelty Clippie) Wed Dec 06 1989 11:16

    I am trying (desperately) to attach an RD31 (ST225) drive to my
    A500 on a budget.
    
    I've investigated the Spirit HDA-506, which works but seems very
    expensive for what you get.
    
    I'm looking at the wedge, but having great difficulty contacting
    RSI to get prices etc.
    
    Another consideration would be the new MonAmi bus expansion which
    would give me three 100 pin A2000 slots.
    
    If I go for the MonAmi (which would make sense as it allows for
    future expansion too) what is the minimum I would need to drive
    a ST506 drive from a Zorro II slot ? From what I gather, I'll need
    a SCSI controller and then an Adaptec SCSI->ST506 adapter which
    works out considerably more expensive than the HDA-506. Is there
    nothing available which will plug directly into an A2000 slot and
    drive a ST506 HD ? (Please don't suggest a A2090/A2090A as C= will
    absolutely not sell them without either a 20Mb or a 40Mb drive in
    this country.) BTW - there is a possibility that I'll be in the
    States during Q3 - what price is a A2090A there ?

3185.1Why not CHEAPHD?GIDDAY::LAWSONThu Dec 07 1989 00:0913
    Why not the "CheapHD" project??? (ref 2318 and 2657).
    
    Jos Loendersloot and I have managed to get these things going. I got
    lucky this week after months of effort. (A key instruction was missing
    from the Doc set..Thanks to Jos' efforts, mine sprung into life.)
    
    I believe that Jos is using the OMTI 5520 and I used the Seagate
    ST11-M. 
    
    We are going to put together a Zoo of EVERYTHING needed to make the
    project and upload it. Watch this space.

    Well I think I'd like the option of a couple of free slots for future
    expansion, but perhaps until funds improve I could go with the CHEAPHD
    then try to buy a A2090 when I'm in the States next quarter.
    
    Please upload the CHEAPHD package as soon as you can.

3185.3Yes why not?JGO::LOENDERSLOOTThu Dec 07 1989 09:3712
    I think you still has the option of free slots for future expansion
    with the Monami, because the CheapHD setup could be connected to
    a A2000 slot as well. 
    
    I have a 20Mb miniscribe (65ms) connected with OMTI 5520 ctl'r and
    performance figures are around 70-110kB/sec for R/W speed (using
    the FastFileSystem). This is about the same performance I have seen
    in several magazines with the A2090 ctl'r and ST225 harddisk.
    
    The controler costs about $70 in Germany and for the interface I
    spend about $20. The harddisk costed me $200. So for about $300
    I have this setup running.

    This could be a cheapskate's dream come true! With the intro of 2090a
    (is the 2091 out yet?), I was hoping to pick-up a second hand 2090 for
    like, well, you know, cheap. I was under the impression that the CHEAPHD
    attached to the expansion port directly. Does eMedia have a PCB with 100
    pin "fingers" to install in an A2000 slot?

    Cheapskaters Hint #27:

    P.M.Solutions is/was offering prototype verions of Mon "AMI" Jr.
    at a discount. I witnessed one connected to an A500 (via a 30 inch
    cable, no less!) with an OMTI-clad CLtd controller installed in one
    of it's slots. Real slick! These are quality boards and the cables
    allow for a lot of possible chassis combinations.

    Yes ! There are two versions of CHEAPHD, one for the A500 (fits on the
    expansion port) and one for the A2000 (fits in a zorro II slot).
