If you're looking for the easy option, the SST39LF040s are easy to get, easy to solder, and Just Work. The parts cost is a little higher, but it does mean less risk...luciodra wrote: 04 Oct 2024 19:22 Has anyone found something similar to SST39LF401C-55-4C-EKE-T for the Rom ? Can you confirm that SST39LF802C-55-4C-EKE can still work ?
Thanks, can you advise me where to get them?DrZiplok wrote: 06 Oct 2024 03:44If you're looking for the easy option, the SST39LF040s are easy to get, easy to solder, and Just Work.

It looks like you're in Italy; I would be looking at Mouser: https://www.mouser.it/ProductDetail/Mic ... aapA%3D%3D
A cheap T48 programmer from Amazon / eBay will handle the GALs, either using their software or minipro. Probably the simplest solution for macOS / Linux programming the ATF1508 is Rosco's Little ATF programmer: https://store.rosco-m68k.com/products/l ... programmer, otherwise you can roll the dice on a clone ATFBlaster and use Microchip's software on Windows.luciodra wrote: 06 Oct 2024 16:12 Now that the board is almost ready, the RAM and ROM are still missing, I have to program the firmware:
for the ROM I will use the programmer. For the rest I would have to buy the various programmers which I will then hardly use anymore...
Can you give me some advice? Can someone do it for me or sell me the components already programmed?

I'm confused: I have this type of ROM card Credo tu fai riferimento all'altra scheda rom che io non ho...DrZiplok wrote: 06 Oct 2024 20:40 It looks like you're in Italy; I would be looking at Mouser: https://www.mouser.it/ProductDetail/Mic ... aapA%3D%3D
Yes, it's absolutely not a cheap thing to put together and especially if you need to acquire tools as well.luciodra wrote: 06 Oct 2024 22:26 This project drives me crazy and I started with my head down without thinking... I involved a friend of mine who is doing a great job and whoever wants to do the same must think that it takes 500 Euros for PCB and components...
What I haven't thought about enough is the programming of the ROMs: I would like to understand if in addition to the Eiffel pic and the motherboard firmware (on the ROM card) there are other things to program. It seems obvious for many here, but for me it isn't...

Code: Select all
Eiffel : PIC16F876A-I/SP
Iksi : ATF22V10C
Narnia : ATF22V10C
Code: Select all
Nessi : ATF1508AS-7JX84
I'm really tempted getting one of those and try to migrate away from relying on the Windows virtual machine. I'm sure I saw some blog post on compiling cupl from cmdline on Mac/Linux too (possibly wincupl tools through wine? - I can't remember)DrZiplok wrote: 06 Oct 2024 20:44 Probably the simplest solution for macOS / Linux programming the ATF1508 is Rosco's Little ATF programmer: https://store.rosco-m68k.com/products/l ... programmer
There are a couple of pre-cooked toolchains for doing exactly this. It works fairly well, though I'd really like to get a better simulation waveform viewing solution...agranlund wrote: 07 Oct 2024 01:25 I'm really tempted getting one of those and try to migrate away from relying on the Windows virtual machine.
