Blake Patterson<p>I am considering the configuration of my Amiga 2000 w/ 68020 accelerator... I would appreciate opinions from drivers of slotted Amigas, here.</p><p>I have an Amiga 2000 with SCSI + SCSI2SD, 4MB 16-bit FAST RAM, 1MB CHIP RAM, etc. It also has an A2620 68020 accelerator (14MHz) with 2MB 32-bit FAST RAM which is meager, but makes things noticeably faster on the Workbench. Most of what I do on this is watch demos and play games, though. All I do on desktop, really, is use AmiTCP and ncftp to bring files over and run IMP sometimes.</p><p>I recently downloaded the Amiga demo 'Downslope' and noticed it's less fluid / smooth with the accelerator enabled. I've seen this before here and there, but assumed that the accelerator was doing my a solid in demos - giving a bit of a boost. </p><p>I commented about this in the Pouet 'Downslope' thread and the developer came in and commented,</p><p>---<br>"Accelerators often introduce an asynchronicity between CPU and chip memory, which adds to chip access latency.<br>This can be worsened by the occurrance of many interrupts, which can cause additional strain on memory on a higher CPU.<br>If we are unlucky, not even the much faster execution time of the higher CPU can make up for the additional latencies and strain on chip memory.<br>It's a matter of focus on the target. There are side effects on higher CPUs which are difficult to anticipate, and usually you have only a limited number of machines for testing."<br>---</p><p>This makes sense, I suppose. Is this common? Are people with '030, '040, '060 accelerators having a lesser experience with demos due to CHIP RAM latency than with base '000? Certainly in some scenarios the more powerful CPU helps hugely for demos and games alike - I've seen this on my '020. But, yes -- demos are the most tightly coded of all Amiga apps, certainly. To the metal, etc.</p><p>So I am wondering now, should I remove the accelerator to get the most out of OCS/ECS demos on the system? Yes, I can disable the accelerator with a right mouse click at reboot, but that gets in the way of keeping Degrader's PAL state in effect, causing a hassle. (it's an NTSC A2000, unfortunately). </p><p>Anyone been down this road? Thoughts?</p><p><a href="https://oldbytes.space/tags/Amiga" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Amiga</span></a> <a href="https://oldbytes.space/tags/Commodore" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Commodore</span></a> <a href="https://oldbytes.space/tags/CommodoreAmiga" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CommodoreAmiga</span></a> <a href="https://oldbytes.space/tags/A2000" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>A2000</span></a> <a href="https://oldbytes.space/tags/A2500" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>A2500</span></a> <a href="https://oldbytes.space/tags/MC68000" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MC68000</span></a> <a href="https://oldbytes.space/tags/MC68020" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MC68020</span></a> <a href="https://oldbytes.space/tags/MC68030" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MC68030</span></a> <a href="https://oldbytes.space/tags/demo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>demo</span></a> <a href="https://oldbytes.space/tags/demos" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>demos</span></a> <a href="https://oldbytes.space/tags/demoscene" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>demoscene</span></a> <a href="https://oldbytes.space/tags/scenedemo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>scenedemo</span></a> <a href="https://oldbytes.space/tags/vintagecomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>vintagecomputing</span></a> <a href="https://oldbytes.space/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrocomputing</span></a> <a href="https://oldbytes.space/tags/vintagecomputers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>vintagecomputers</span></a> <a href="https://oldbytes.space/tags/retrocomputers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrocomputers</span></a> <a href="https://oldbytes.space/tags/retrogaming" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrogaming</span></a> <a href="https://oldbytes.space/tags/hardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>hardware</span></a> <a href="https://oldbytes.space/tags/vintaghardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>vintaghardware</span></a> <a href="https://oldbytes.space/tags/A2620" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>A2620</span></a> <a href="https://oldbytes.space/tags/A2630" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>A2630</span></a> <a href="https://oldbytes.space/tags/DaveHaynie" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DaveHaynie</span></a> <a href="https://oldbytes.space/tags/ZorroII" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ZorroII</span></a> <a href="https://oldbytes.space/tags/terriblefire" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>terriblefire</span></a> <a href="https://oldbytes.space/tags/oldcomputers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>oldcomputers</span></a></p>

Blake Patterson<p>Someone asked me about the PGA chip sitting on my Mac Studio in a recent toot showing some little glass figurines I brought back from Murano, Italy. They asked if it was a 386. It is, in fact, a ceraminc PGA 68-pin MC68HC000RC12. I didn't have a very clear shot of this chip I recently picked up off eBay, so I took one this morning to share with the person who asked -- and it turned out a rather striking image, to my eye. </p><p>I thought I'd share. </p><p>(I recently purchased the chip in new condition on eBay because of its nice, square purple ceramic and gold appearance (just to have as a desk bauble) and with a nod to the many MC68K systems I've used over the years -- and still use today.)</p><p><a href="https://oldbytes.space/tags/coinforscale" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>coinforscale</span></a> <a href="https://oldbytes.space/tags/Motorola" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Motorola</span></a> <a href="https://oldbytes.space/tags/CPU" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CPU</span></a> <a href="https://oldbytes.space/tags/microprocessors" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>microprocessors</span></a> <a href="https://oldbytes.space/tags/chips" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>chips</span></a> <a href="https://oldbytes.space/tags/hardware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>hardware</span></a> <a href="https://oldbytes.space/tags/Mac" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Mac</span></a> <a href="https://oldbytes.space/tags/Lisa" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Lisa</span></a> <a href="https://oldbytes.space/tags/Amiga" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Amiga</span></a> <a href="https://oldbytes.space/tags/AtariST" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>AtariST</span></a> <a href="https://oldbytes.space/tags/MegaDrive" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MegaDrive</span></a> <a href="https://oldbytes.space/tags/AtariJaguar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>AtariJaguar</span></a> <a href="https://oldbytes.space/tags/PalmPilot" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PalmPilot</span></a> <a href="https://oldbytes.space/tags/FreeScale" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>FreeScale</span></a> <a href="https://oldbytes.space/tags/MC68000" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MC68000</span></a> <a href="https://oldbytes.space/tags/MC68K" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MC68K</span></a> <a href="https://oldbytes.space/tags/ceramic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ceramic</span></a> <a href="https://oldbytes.space/tags/photo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>photo</span></a> <a href="https://oldbytes.space/tags/coin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>coin</span></a> <a href="https://oldbytes.space/tags/technology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>technology</span></a> <a href="https://oldbytes.space/tags/vintagecomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>vintagecomputing</span></a> <a href="https://oldbytes.space/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrocomputing</span></a></p>
