Boards are on order!
I have ordered 30 boards, all with the bottom side birdseed populated. Boards are purple with a ENIG finish
The good news is that although the order as a hole was pretty expensive the per board cost is actually lower than I expected so it's looking like the final price will...
Very likely they will be remarked 15ns parts. At least that is what the last batch of 10ns ones I brought from them seemed to be. Still real 71B74's though so are usable on designs that tolerate slower parts
Yeah the TAG SRAM's are a pain, UTSource has them but you will get 15ns parts no matter what speed grade you order (and they will remark them so watch out) Quest has genuine 12ns ones (or at least they did) but they are not cheap
Yep :) Combind ST-Nic based ethernet card and accelerator for the LC II / CC. Will probably do another deign based on annother card I have that also works on the LC I (and has cache so will be faster) but that will be a significantly more expensive card to produce
I was hoping to get these ordered this month but my projects budget ended up being eaten elsewhere
All being good they will be sent off for production at the beginning of next month
Once I have the boards and have verified the revised version is OK I'll contact everyone who has expressed...
Oh nice! We where looking for complete unmodified images of rhapsody (particularly DR2) when I was active on MG about 10 years ago!
Thanks for uploading them :)
Right, Have made the necessary alterations to the board and am having a look at getting a run made
Purple seems to be the most popular colour so we will be going with that
Do you guys want them with the bottom birdseed PNP assembled? Doing some rough pricing you would probably be looking at £60...
Interestingly I don't find the LC cases to be that brittle, of all my LC's I only have one where a tab has broken from normal use and one more where a internal tab was broken during shipping (But has been fine for years after glueing it back on) Wonder the if a different plastic mix was used on...
Sort of, this approach only works because this the accelerator is not really a PDS card, it is just hanging a faster CPU off the bus and the PDS connector happens to convinently have all the needed signals . If you wanted to do the same thing with two PDS cards you would need additional...
I have PNP data already made :) Didn't do it with the test batch as it adds quite a lot to the prove for a small run, will likley do it for the next run
There is a common issue with the screens failing on the early floppyemu's, the Zebra strip inside the screen starts loosing contact with the board causing issues. Try pressing on the top center of the display and pressing reset, if you get a display then you just need to get a replacement...
I had a quote back form PCBWay, $2300 for 5! yeah I think I'll pass on that. Will have to go for a normal colour.
So for those interested, what colour would you like? I will probably only do a single colour so I'll go with whichever is most popular
The boards have now been fully tested and work...
There seems to be quite a bit of interest so I will likely do at least one run, In terms of colours I really want to get some made with clear solder resist and a black base material (Like OSHPark's "After Dark" boards) But I'm currently waiting to hear back from PCBway on if that's possible...
It's a matter of finances, Getting a reverse engineering project like this to the point this is at is very time consuming and often expensive so being able to sell them afterwards justifys that time / cost. Additionally projects like this help support other ones that will likely never make any...
