Sprinter. Второе пришествие

[Shockwav3]

What's the maximum speed I should consider for the 128K*8 SRAM?
IS61C1024AL-12JLI would work as well?

i recommend to use CY7C109-15 or IDT71024S15. alliance memory may have artifacts on Sprinter.

both CY7C109-15 and IDT71024S15 and alliance memory and w24010as-35 work

альянс артефачит же, нафиг он не нужен. а винбонд у тебя выдавал в ваф плеере артефаки и ещё там где то. забыл. зачем тогда про них говорить? лучше использовать то, что не даёт артефактов.

Для запуска любая пойдёт, дальше уже по поведению выбирать, CY и IDT лучше всего работает , Winbond на одной из 4х прошивок работал вполне стабильно, альянс изначально устанавливался

Хотел ещё ISL61C1024-20 испытать, но в наличии было только 2шт., поэтому эксперимент провалился

I've gone with IDT 71024S15TYI since I could source them locally for cheap.
Only waiting for the SIMM slot for now, then my Sprinter is complete

[Shockwav3]

Hey there, now that my SIMM slot has finally arrived (8 weeks delivery time) I started up my sprinter for the first time yesterday
Works great so far, except that booting from disk isn't possible. I'm using this image from the velesoft site: https://velesoft.speccy.cz/sprinter/...age+writer.zip + rawrite3.com from freeDOS (http://www.ibiblio.org/pub/micro/pc-.../disk/rawrite/).
On the DOS machine I can see the contents of the disk, but on the sprinter I get maybe 10 seconds of disk activity before the computer hangs. Very occasionally I get a reboot.

What would be an alternative approach to make a HDD bootable? I successfully formated one of my drives on my DOS machine and copied everything from the Bootdisk over to the freshly formated partition, sadly that didn't work either.

Shockwav3, The disc must be prepared directly on the sprinter.

Here is the instruction https://zx-pk.ru/threads/10983-sprin...l=1#post879887

I can't even get that far ... booting from floppy doesn't work.
This is the furthest I've got. Usually it hangs at the "Start from Diskette ..." sometimes it gets to the OK. This was the first time I actually got the invalid bootsector message.
I'm using a KR1818VG93 from Quasar (the one with the "windows" in the case). Exchanging it with another one, I get the "OK" message a lot more reliable.
Both chips and the drive used work nicely on my Pentagon48.


I've ordered a MB8877 ... maybe that one works more reliable when used with HD floppies.
