Speed comparisons A500 etc.

[Tenacious]

not to hijack the tread. but i am in a bit of the same situation. i have a beloved derringer 030 (50mhz) and i really love the speed and the 32mb ram it adds. however. i use the trumphcard sidecar expansion. with a outdated scsi controller and a dying hdd. and i have tried all my scsi drive. but the controller wont recognize them. in another tread im told the controller wont accept any disk larger than 300~ 500mb. my smallest drive is 1 gig. and the sidecar is annoyingly large.
Is there any ide controller made for the internal cpu slot that is compatible with accelerators?

As for the tread. the derringer performs really well in the 500+.
i dont remember the number in my head. but the graph in sysinfo is close to the performance of an a1200 with blizzard 1230.

Now my a500+ is picked appart in bits and pieces for upgrading and fixing the battery leakage on the main board. it is stopped. and i hope to add a battery of the newer coin style. (have some schematics to work with..)
And i want to hack the derringer to accept 128mb ram

But my main interest is to find a ide controller that can sit between the derringer and the cpu slot... anyone got any clues?

Some thoughts:

If your Derringer and Trumphcard play nice together, that may be the rare pearl to hang on to.  I've never worked with a Trumphcard, but, it sound like it needs an updated ROM to allow more modern sized HDs (at least up to 4 Gigs).  You could contact TJLazer on this site to see if he has an update for this interface.
Or, you could find a smaller SCSI HD.  300 MB sounds small by today's standards, but, for tightly coded Amiga software, it may be very livable depending on your purpose for the system.

ICD made an IDE interface that sandwiched under the 68000.  I've never tried it, but I'll bet its ROM is old, too..  There seems to be NO demand for their designs today.  That may speak volumes.

1) double memory indirect
2) some bit field instructions
3) (bd32,An,Xn*SF)

4) MOVEP 5) The BCD instructions ABCD,SBCD,NBCD 6) CMP2,CHK2 7) CAS2 32x32->64 MULx and 64/32->DIVx

[biggun]

There isn't room in the tiny Vampire fpga for full 68020 support but many of the 68020 instructions are available. Missing are:

1) double memory indirect
2) some bit field instructions
3) (bd32,An,Xn*SF)

Phoenix does support now all 68020 EA-Modes in hardware.
Including
 1) double memory indirect
and
3) (bd32,An,Xn*SF)

This is at the moment in testing in the Vampire card.

The last I heard from Gunnar was that 64 bit integer MUL*/DIV* are in the Cyclone II Vampire now. I believe MOVEP is missing from most current builds but there are some reports that trapping is successful (only needed for old games anyway). I'm not sure of the status of the BCD instructions but they are small and simple so if they have been overlooked it is probably because other things have priority. CMP2, CHK2, CAS, CAS2, TAS, etc. are also unlikely to be 68020 ISA compatible in Phoenix but the 68040 and 68060 fail also as there is no CALLM/RTM. What's important is the percentage of 68020 Amiga software that executes and not the compatibility of the 68020 ISA.

I can't believe all of this fits in a tiny Cyclone II! The 68020 compatibility should jump, at least with compiled code and the AmigaOS. If you can fit support for all the bitfield instructions, it will be 68020 compatible for practical purposes.

The Vampire 500 comes with IDE build in - and is probably the fastest accelerator for A500.

Yes, i am aware of that. but that will render the derringer unused. and it is out of the question.

Hmm.. might be. but i cant use my action replay...

The sidecar itself is basically just an adapter that adds two zorro II slots. not including a buster chip, though. have no clue to what that means.
But the controller is the IVS Trumpcard. can be used in A2000 as well.
To my surprise i find a DKB spitfire inside the sidecar. cant remember purchasing it. Anybody got any info on the spitfire?

Or, you could find a smaller SCSI HD.  300 MB sounds small by today's standards, but, for tightly coded Amiga software, it may be very livable depending on your purpose for the system.

I have tried. but no success. the only 300mb quantum drive i found (on a dump) was dead. Don't know if ide adapters will work. and another problem. the prep tools of the controller is seriously confusing. and you cant use hdtoolbox. (AFAIK)

I had a ICD adIDE before. but i sold it, never got payed and I cant get the hold of the guy who "bought" it....

Looks like another SCSI interface.  Google?  

[ElPolloDiabl]

To install a hard drive manually. Go online to one of those old hardware places and find the model number of your drive. You should find the info to set it up.

I previously used a Supra28 and SupraRAM with 2MB but now I use an MTec 020/14 and 882/20 with 4MB, it's not that much of a speed difference between the two but I prefer an internal solution and both are great additions to any vanilla A500.

For more speed benchmarks I suggest checking out Amiga Hardware Database.

From what do you boot the system?  Did you find compatible HD interfaces?

I use an Apollo500... it's a sucky controller but it's the only one I've found to be compatible with the MTec so far, with I could use an internal solution or my GVP500HD8+ but no. :/

[Brian]

Just found out my AlfaPower also works with the MTec... my A500 happily autoconfigured the fastmem both on the Mtec and in the AlfaPower for a total of 8MB and disk is currently formatting however it's painfully slow.

Have looked into IDE68K?

http://www.students.tut.fi/~leinone3/ide/ide68k.html

It seems that no one has tested this with the Derringer, so there would be no guarantee that it would work in your config. They're for sale on amibay (or were last year at least).

There is no need to use normal format on drives, just use QUICK. it will be a few seconds. i have a Alfapower i added dual cf slots to using the cutout on the back where they intended a ide cable to come out. works great and looks factory still.
