Ah great stuff, I've been wanting rom clearance there for ages. Not on rev5 motherboard though (the most common one). But it doesn't matter really, I always thought kickstart switchers are useless. The revision5 A500 ROM layout feels like it has been deliberately designed to thwart any attempt to f...

Thanks for this riser @go0se I ordered a batch of 4 layer ones from JLC, and they arrived a few days ago, really work very well in my A500+. Really like how the ide port lines up perfectly with the expansion port exit. Have tried with a lot of different software, no problems at all :thumbup: Glad i...

A machine in such lovely original condition would be wasted on me!

Its ok.. I have an extra row between the TF536 ad the relocator.. i've also got insulating tape over all of the bottom of the card... It is indeed a rev1 which eventually i'll solder down properly to a relocator. Ok, great, I don't want to be responsible for breaking your CDTV, It doesn't seem to n...

terriblefire I've just noticed a potential nasty issue with the CDTV relocator from the images you posted on the threads. If the JTAG header is populated on the TF536 then +5V and GND on the underside of the JTAG male header pins could touch on the metal cap of C163. :shock: I hadn't considered thi...

The relocator is still abit high for me i'll live with it. Is that Rev 1 536 you are using soldered to the relocator using just rows of male pins or can the relocator + 536 still be separated? i.e. with both male + female pins/receptacles used? Using a 90 degree IDE header helps further with lid cl...

That's the reason you just bought that spare CDTV right?

What is the issue?

No sure if those are equivalent without comparing the data sheets:

I ordered the Nexperia versions from Digikey.

Maybe someone else who has looked into it can recommend a suitable alternative from RS or Farnell.

Hi Gadget, I think you are mistaking the IC part numbers for the level shifters and the IDE buffers. IDE buffers IC4, IC5 and IC6 should be 74VHC245PW as per the BOM tf536_full.csv here : viewtopic.php?f=76&t=2728#p38246 All three need to be populated and the 6 corresponding resistor networks re...

Also, I have ordered 10 of these PCBs and only require 2 or possibly 3, so, should they work, anyone who wants one can have it for the price of postage to wherever you are - Provided you can supply your own 2 X 16 X 2.54mm headers and 32 position ZIF socket. Some cheap fake 3M ZIFs that should do th...
