Re: PicoMEM : Pi Pico on ISA, with full Memory and I/O bus access

IBM 5150 was released on August 12, 1981. First Pentium was released on March 22, 1993 - it's 12 years later, but... ... it was already 30 years ago :) I still do not have a machine based on the 8088 processor, but I am tempted. It will probably be one of the new clones, as the original era hardware …

When it comes to data transfer speed, do you think that CDROM emulation is possible with PICO ? (I'm thinking about ISO images, or even better CUE/BIN with audio track support). On the other hand RP2040 based ZuluSCSI reaches up to 9.1 megabytes/second, so...

Reminds me of C64. Unlike contemporary consoles VIC2 didnt support hardware scrolling beyond 7bit offsets, that 8th pixel required copying 2000 bytes to manually shift text and color ram :( Big oversight considering C64 can only copy ram at <120KB/s with all the tricks. Smoothly scrolling screen at …

Also to minimize noise, you can remove green resistor which is soldered in place of U8 and replace it with proper 7809 linear voltage regulator. I'm very satisfied with this modification

I have the same card as on third photo. In my case it was "farting" OPL3. I replaced LS262 clone with genuine OPL3 but it did not improve the situation (so if you are thinking about it - it's not worth your effort). The culprit was the broken U3 - 74LS245. I replaced it with a 74HCT245D and the card …

Sata II speed (300 MiB /s) will be in perfectly fine. It's ICH7 (which is used in 99% motherboards with Intel 945, G31 even G41 chipsets) just lacks additional features like AHCI / RAID. Consider better board only if you need those features or more than two SATA devices.

Although there are ICH7 variants that support AHCI/RAID, this motherboard looks extremely truncated (only 2 physical SATA ports). So I suspect that the basic ICH7 variant (82801GB) was used - which doesn't support AHCI nor RAID. https://en.wikipedia.org/wiki/List_of_Intel_chipsets#Southbridge_9xx_ …

This board is based on G31 + ICH7 chipset. ICH7 doesn't support ACPI so, you don't need specific driver for SATA. https://www.intel.com/content/www/us/en/suppo … chnologies.html

If we're already mentioning via chipsets... Being an Intel fanboy, I was surprised at how pleasant it was to work on Jetway's P4XFCU board (VIA P4X266E chipset 400/533 FSB).

If your problem is related to the IDE DMA then maybe try the Universal ATA drivers ? http://alter.org.ua/en/soft/win/uni_ata/uni_ata.php (I'm not sure, I'm just guessing).
