thank you so much so far everyone

Quick check. It looks valid and it does boot in emulation. Oddly enough it is different than previously known 1.1 but version strings are still same.

morch · 21 December 2021, 19:28

I wonder if there's anything helpful in the rom...

If you can upload both versions I can take a look some time.

In the zone. (first rom is 64k because it was stored in 64k OTP EEPROM even if only half of it is visible in address space)

mark_k · 22 December 2021, 12:31

Data in the old/previous 64KB image is not just doubled, each quarter of the data is different in two bytes (probably corresponding to the ExpansionRom data). Maybe changing jumper positions changes which half of the ROM data is visible? (Could that be related to selecting the on-board RAM size?)

currently no ram attached and no jumpers on the 2 ram switches internally

i put in this ram, i think its the correct arrangement but it isn't detected, maybe i used the wrong type :/

one of the ram chips has a notch along the base where the contacts are... they sent me wrong type

morch · 29 December 2021, 13:43

My molex PSU came and it turns on with it... Any idea where I would see if it has drivers?

The install directory only has non english language installers:

Devs I guess?

No drivers visible in these screenshots. If it autoboots, the driver will come from ROM.

So the install disk is probably just a drive preparation for older workbench?

I guess I need to back it up to the sdbox now just do a copy dh0: sd0: all clone ????

Jope · 29 December 2021, 14:53

A better idea is to lha it up with no compression. You will get CRCs and it will preserve all the filesystem attributes. Fat32 is not amiga compatible in every sense.

Thank you that will be helpful... Small issue I can't find my 512k ram expansion so ordered 1mb as been meaning to since I now use 500+

morch · 03 January 2022, 18:02

was just wondering if the people got the roms they wanted, and where they landed up stored?

Jope · 03 January 2022, 18:29

Hope Toni uploads a new rom package to the zone as new roms get added to winuae.

so im not needed for anything else at the moment, let me know if you do need anything

Toni Wilen · 04 January 2022, 18:48

Unfortunately it isn't that simple situation because this ROM has 100% identical version numbers compared to previous dump, functional differences are unknown and this ROM can't be dumped 100% without ROM reader (part of ROM is hidden under IO addresses, sometimes "hidden" part of ROM contains something interesting)

I'll probably add this as an "alternate" version later.

morch · 04 January 2022, 20:47

Would one of the cheap eBay eeprom things be able to read it... From my photos I can't even recognize where the ROM is! Lol

mark_k · 04 January 2022, 20:51

The EPROM is the large chip with ceramic package, label on it says IC6 V1. Any EPROM programmer should be able to read it.

morch · 06 January 2022, 21:13

2 updates:

i made a dump of the HDD thank you
https://amiga.retro-robot.co.uk/REFERENCE100backup.lha

some nice mods in there

I finally got some matching 1mb simms and put them in but they arent detected, could it be bad ram since the pair needs to be good? or do i have the wrong type?

not the mysterious switch at the back which read is attached to "scsi commit" on the pcb, i guess for the scsi
