Ooh, new toys from Mr. Dunklee. UPDATED ADDED AT BOTTOM OF POST

A parceiro with faster SD card access, and no longer requires any PAL mods to the a1000 daughterboard. You could think of this as a "minor" rev, except the changes were partly done to facilitate the new Parceiro Accelerator, shown here:

A 68SEC000 clocked at 28MHz, software controlled (no dip switches, etc). I'm beta testing for David. Like an AdSpeed for those in the know. The software control is done via a WB1.3 extension menu for Parceiro, very nifty!

SysInfo says I'm at 0.81x of an a2500 but 1.37x of a stock A1200, when clocked at 28MHz. This part surprises me, because I thought the only difference between an A2500/020 and A1200/EC020 was the address-bus width. Not cache or other performance?

Disk throughput goes from ~406KB/sec to ~765KB/sec. All speeds with a grain of salt, since sysinfo isn't a great benchmarking tool.

UPDATED: apparently myself and another fellow (Gord in Canada) have PAL variants on our A1000 daughter-boards that didn't like the new Parceiro + Accelerator combo, and resulted in me getting less than 28MHz reported, and less than stellar results in the perf tests!

Been working with David (like drinking from a firehose!), and he believes there's a few different remedies / solutions. I'll be trying both a new set of PALs, as well as the existing PALs but a new firmware for the Parceiro itself, and should see MUCH higher numbers than I reported earlier.

For example, while I reported 750KB/sec on the SD card, David is getting more than 1MB/sec. And while I reported 1671 Dhrystones, 1.74Mips, 1.37x A1200, and 0.81x A2500/020, he's reliably reporting 2850 Dhrystones, 2.97Mips, 2.34x A1200, and 1.38x A2500/020. Basically, the expected perf is some 70-80% faster than the numbers I originally reported!

Update: 6/23/2023
Received a FW update and managed to flash it using the Lattice tools. The FW update got me much better performance than earlier posted, but still not quite maximum. Then I got a new set of PALs for the daughter-board of my A1000 from David, and finally achieved maximum performance and reliable results.

Dhrystones: 2839
vs. A1200 EC020 14MHz, 2.33
vs. A2500 68020 14MHz, 1.38

0.61x the speed of an A3000, without upgrading to a 68030! And now getting 970KB/sec out of the SD-Card hard drive.

My A1000 feels reborn.

The "new AdSpeed" is imminent.

My understanding is that it needs to be paired with a new rev of parceiro. I'm sure if that's the case that David would be accommodating.

Note that it still isn't compatible with Rejuvenator equipped Amigas, but David is working on that. Feverishly? Frantically? Occasionally? Hard to tell ;)

Out of curiosity, how do I best get in contact with David to order myself one of those babies?
I picked up an Amiga 1000 last week (been probably at least 25 years in the making. Ever since I saw an Amiga history article in a video game magazine) and am toying with the thought of making this my new main machine.

Inquires should be sent to amiga.parceiro [at] outlook * com

and tell him AmigaLove sent you. ;)
