- First thing I'll say is... wow! $429 cdn (Electronics 2001, Toronto). This
- little card is a 68EC030 (optional full 030) at 25Mhz. It has a socket for
- math (although it's PLCC), and attachments for 32bit ram.
-
- THE PACKAGE, AND INSTALLATION OF SAID.
- Well... documentation is sparse... three sheets of 8.5X11 paper... but I
- don't think they could have written much more without getting too verbose.
- The installation of the card is easy, but they used the type of socket that
- consists of little round holes surrounded by little beads of plastic. I had
- trouble getting the 68000 into them as they could be a micron wider... :)...
- Actually, my 68000 was not in good enough shape to fit into the card, so I
- installed my 68010 instead. The card didn't seem to mind. I'll probably pick
- up a 68000 at the Commodore show in December... they're usually about $7!
-
- FIRST IMPRESSION.
- Holy boot time batman! Damn thing booted before the monitor warmed up!
- ..even floppy access is faster.
-
- CURRENT SYSTEM.
- -Microbotics 68030@25Mhz - no ram - no math
- -GVP series II hd w/ 105meg 19ms drive.
- -4.5meg of ram (1meg chip) on ICD board.
- -original IBM XT power supply ($30!!!)
-
- WHAT IS IT, DAMN IT!?!
- There was some confusion among programs as to what the darn thing was!
- Xoper thought it was a 68020/68881! GVP's little system thing correctly
- identified the 68030 with inactive MMU, but it let me look at all the
- non-existent MMU registers anyways! It also was under the impression that
- both caches were always on, but you can check it out correctly using the
- cache control register query. SetCPU, and SetVXL (both included with the
- package) identified everything correctly, and performed predictably!
-
- THE FIRST GURU!
- Well, all was not right in Amigaland last night. I tried turning on the
- data cache, and neither my HD or any of my software seemed to have any problem
- with it. So: I put it into my startup sequence! What a spectacular crash!
- AdRAM (included with the ICD RAM thingie) was under the impression that I had
- ram all over the place! It started adding ram that I never knew I had
- (ended up with about 10 meg I figure!)... anyways... it turns out that it's
- having the data cache on that confuses this little program... so the fix is
- to have SetVXL (or SetCPU) after AdRAM in your startup sequence. There is,
- by the way, no physical conflict between the AdRAM daughter board for the Gary,
- and the VXL 30 board.
-
- OVERALL...
- Compile time of TeX went from 30mins to 7mins, but Manx's asm crashed
- on the last file (where it didn't before...) with a pointer out of range...
- I'll have to talk to Manx about this. Professional Page zips along, and
- floppies seem to have a perceptible speed increase of icon display. LHArc was
- pleasing, but I just can't wait for LZ now!
-
- LEMMINGS...!
- You probably did a double-take at this last heading... well it just has
- to be said that Lemmings works better with an '030! No, it doesn't run at
- speed 78... (that could be fun!) But it does load faster, and the pauses
- between screens are almost instantaneous! And... when you nuke 'em... they
- blow up faster! Hat's off to Psygnosis for creating a game that works
- well on another processor! (and I'm not talking '286 trash, either!)
