According to a PDF entitled 'Apple ROM Matrix', there is a listing for a ROM with checksum 852CFBDF for 'PowerBook 5300 and Assistive Technology Freestyle'
180MHz 603ev CPU upgrade for 5300ce?
- Thread starter Trash80toHP_Mini
- Start date
Don't got it. It's listed in the MacROMan GitHub repository but is not included in that repository's TestImages folder.
Oddly, https://docs.google.com/spreadsheets/d/1wB2HnysPp63fezUzfgpk0JX_b7bXvmAg6-Dk7QDyKPY/ has it (which makes sense, since it and MacROMan track each other), but it includes details that imply that I had the ROM at some point to validate -- but if that were the case, it should be in TestImages.
I'm curious if the PDF is just a printout of my spreadsheet of the same name?

FYI This list is missing the PB1400 166MHz ROM... in case you're able to request an update.
Ah; I had that in my "to do" list, but never got around to it. I seem to recall joevt and I both updating our MacROMan forks for that one, but I missed adding it to the sheet.
I would like a copy of that dump when you get around to it. Or maybe someone with a complete 5300 can do it.
Oh yes, haven't forgotten. The thing is, I'm out of town. If a PB5300 user hasn't done it by the weekend after next, I'll get on it.
PB1400 166 dump added to the sheet now. I'm also looking forward to the 5300 dump
Excellent. Some additional data for the 1400/166:
-The CPU is a 603ev
- It supports 8-64MB (this applies to the early 1400 ROM as well).
- We're assuming it will boot Mac OS 7.5.2 but I'm not sure if that's been confirmed. I suppose there's no real reason it shouldn't.
n.b. There's a bit of a misconception floating around about some models only supporting up to 56MB, but IMHO it's a misunderstanding of a technical issue.
Might the 5300ce be using the 1400 ROM to support its 800x600 panel?
Nah there's just one ROM between all the models.
That's what I'd figured, but thought to ask. Thanks!
So it's an overclocked 5300c then
Basically, yeah.So it's an overclocked 5300c then
It does have the "5300ce" badge, however, so it apparently is a genuine 5300ce, aside from the display.

The resolution bump is considerable in the ce, fine also for the larger 1400 display, but a pathetically low resolution by the time of the 3400/TAM era. 1024x768 should have been available well before WallStreet, even if in a 3400/Kanga sized panel.
I haven't the foggiest clue what LCD panel I should look for to restore my PB5300's ce-ness.
And even if I did, I somehow doubt I'd be able to afford it in this day and age (sometimes I wish the social media influencers hadn't discovered old Macs! The prices have nearly tripled in the years since they did!)

You'd still need the correct display flex cable and that's not going to be easy to come by.
The c and ce used different cables?
I knew the cs, being passive matrix, used a different cable than the active matrix panels, but I didn't think the different res active matrix panels did, though I'm not surprised.
Probably my best chance of acquiring both the ce panel and matching cable would be from a parts unit.
