I have a couple of H4s to build, I'd better get on it so my finished one has company :)

I did get it first working back in June 2020, so not quite that long really...it's just that I broke it earlier this year :oops: when trying to sort out some issues with the first H5 build (getting there, though the floppy issue is still not resolved yet). :roll:

I still have one H4 and an H5B1 to build at some point (plus the second TF536...waiting on PLD & DRAM courtesy of the global shortages).
Maybe it should be a friendly competition to see who builds up their next system first? Spoiler alert - it's almost certain to be you! :lol:

Not so sure about that, I need to run through the BoM and double order first!!

@rubber_jonnie I doubt I will manage to check what I'm still missing before Christmas, so I still think you have a good chance to build yours first!

Spent much of the day trying to get my temperature down after the booster jab yesterday afternoon...so very little progress as a result.

Also, bad news in that my plan to fit an Exxos ST version of the TF536 will have to change now all the boards have sold out. :(

Oh well, I will see what else I can put in this H4 (probably the TF536 that I had in there before, but maybe with the updated CPLD firmware to allow the IDE to work)...

That booster (jab) is a right pain isn't it?

Pity about the other booster (TF536) though. Maybe wait for the Buffee?

Aye, those are not the fun type of booster...

Yes, much worse reaction than the first two jabs...temp is still high so it looks like I will be working from home today (not supposed to go in if the temp is over 38 degrees)

I've got one built up TF536 & another birdseed board (needs the CPLD and RAM ordering) so I may make do with those for now...

Nope, but they might be more urgent given the recent variants!

Ok, so having finally fitted the TRUDIE v5.2 onto my H4 (working well with HDDriver 11 7 TOS 1.04), I'm going to try and re-fit the TF536 to this system...

First problem is that the 27C4096 EPROM I've put in this H4 is the modified TOS 1.04 plus a special EmuTOS image to allow it to load EmuTOS from Floppy!

So, I need to put in a different EPROM with TOS 2.06 and/or EmuTOS before the TF536 will be able to boot...

Looks like I will have to dig out my "spare" Hitachi EPROMs, check at least one is blank & then program that up with a suitable image as soon as I can...

:sigh:

@JezC I have a ready done image somewhere, will post it later.
