-----------------------------------------------------
OTHER OPTIONAL STUFF
-----------------------------------------------------

Optional RTC stuff - Battery Holder, oscillator, RTC chip. 1.44 FLOPPY GAL.
I do plan to stock the programmed GAL in the store "soon".

Of course the chips themselves are not supplied. They have to come from the store or a donor machine. Sadly a lot of my stock of chips was depleted some time ago. There will likely be some more next time I scrap some machines but this could be a long time before I get around to it.


There might be other items I have currently missed. If anyone spots anything than let me know and I will update the list above.

Pardon the relative newbness of the question, I have followed the project with great interest, but perhaps not to the greatest detail.

I'm planning to populate my freshly ordered H5C1 with salvages from a broken-motherboard 1040STF (no blitter).
While looking at the BOM, I noticed the ROM link leads to the TOS 162/206, the STE dual-ROM.

Is this as intended, or are the TOS 104/206 ROMs more suitable?

I realize that in either case, the TOS decoder board might be necessary to fully utilize 206 ROMs.

@StealthGunner385 the Tos1.04/2.06 would be a better choice and as you say, you'll need a decoder board for 2.06 to work :)
If it ain't broke, test it to Destruction.

@PhilC thanks for confirming what my gut had told me. Considering the donor board's original ICs, looks like it's time to get a new CPU, MFP, DualTOS and Decoder.

@StealthGunner385 ST chipset only supports TOS104,TOS102 DUALTOS, but I don't suggest them as I am actually discontinuing that combination. It's why I am suggesting the TOS104, TOS206 ROMs. Then at least if you decide to use the decoder board, you already have TOS206 ROM ready for it.

Assuming an STF donor.

And it is working.

What parts do I need outside the donor. I know there are some header pins. The 72pin socket for ram would be a must?

What else can I NOT get from the donor?

You don't need two reset switches and you can use 68k processor in DIL package if you want to. You just have to solder in a socket for it.

The MFP is DIL on most Ataris (all?) and not PLCC as on H5c1 so nothing you can find on a donor board.

The ESSENTIAL list is what you need from my store.

while you can reuse your old CPU, I really would not bother and just get one of the 68HC000 CPU's from my store.
