I've recently (finally?!) upgraded my A1000 to a A2000 and am now in
the market for a SCSI adapter, hard disk, and additional memory. I'm
currently leaning towards GVP's IMPACT SCSI + 8 to which I'll most
likely hook a Quantum 105 and populate with SIMM memory. Another
possible configuration is a hardcard (Supra's Wordsync, GVP HC,
Microbotics' Hardframe/2000, or A2091 (tho' I think it has non-SIMM
memory expansion, which I won't use) and Microbotics' 8-UP! SIMM.
How will I encounter [rumored] problems with a DMA vs. non-DMA SCSI
interface? Will the 1-board solution provide equivalent performance
to a 2-board solution? Is there any reason not to use SIMM memory?
Please email responses; I can post a summary later. Or perhaps I've
missed answers to these questions when previously posted and someone
can forward me those responses.
'ppreciate the help... thanx!

I'm As far as I'm concerned the HardFrame 2000 is THE best controller out there. It has performed flawlessly on my A2000 w/Q105S since the day I got it. It only has minimal slowdown of about 50K/sec when using Interlace, 16colour, overscan screen and normally transfers about 750K/sec. Beautiful controller. It also allows the mounting of the drive on the card (In other words, Hardcard). You could then add a separate memory board. (Microbotics 8-UP or ASDG would probably work out pretty good). -- _ Craig Lemon // |_| Kitchener, Ontario \X/ | | M I G A Amiga 2000 -- 2400 bps -- AmigaUUCP 1.03D ..!watmath!xenitec!wcbcs!lemsys!clemon ..!watmath!xenitec!wcbcs!{_clemon|AKCS.clemon} ^^ Not Reliable Yet "Yes, it's my real name!!"

I'm quite pleased with my HardFrame w/Q80S too, but how do people get those transfer speeds? I have only 1 MB without new Agnus, maybe that's why I get a only little over 500K/s (?) Oh, and that's with diskperf (a version modified to run on 1 MB amiga...). Last saturday I got terminal line to my apartment (max 38400 bps but with amiga's standard serial port only 19200) and I get sometimes blurps of checksum errors from dnet when writing to HD...I guess serial.device or dnet don't get enough time-cycles 'cause HF takes "too" much...any ideas? Well, I got successful transfers but those errors are annoying when you should be having THE best controller :-) --> // This msg is sent by: Ari Yrjola + Internet: ayrjola@hut.fi -->:: // Address: JMT 3B 231b + BITNET: lk-ay@finhut.bitnet --> :X/ 02150 ESPOO ,Finland,Europe + VoiceNet: +358-0-468 3088 ````````````````````````````````````````````````````````````````````````````
