What's new Pussycat too?

Here is what I had to say about Fujinet in another thread:

So the FujiNet has a MicroSD card slot where you can load .atr .atx and .xex files. It also has WiFi and Bluetooth to connect to the internet where it can access a file servers that hold all the files you want. It can be used to access BBS’es and printers..

Matt got there first

 

Great and complete info, thank you, Matt! Also thanks to Richie for his kind reply.
So the AVG Cart is the top, but no network/connectivity services?

 

Matt is your man for a full breakdown but yes, all of the things you said...And more..

 

Nice win there Richie, no charges...

 

I was surprised too, to be honest, but not complaining.

 

We takes lifes little mercies with a smile..

 

Almost there @Baz...

 

Anything with ORIC on it has got to be class, Daz....

 

Talking of ORIC's My cable video cable turned upto day,(Retro Computers one good old Ian)

I've been running it on your power supply Andy ... Oh boy the poor old Oric really fry's to the point when it crashes.
I appreciate that the changes to the Oric Microdrive will see it running much cooler , but think I may knock up a device that sits between your current PSU and the Oric.. it currently getting 15V DC not 9V I'll see if I can get a 9V Switch mode Regulator in the middle or even fit inside the original PSU which would be better.
I'll use a bench PSU for the ORIC for now, but I'll be getting on with the micro drive and the Drive mech swap.

 

Sadly one of the previous owners had butchered the vias for the voltage regulator so it’s not a pretty repair. What you could do is change the LM7905 again for a Traco power TSN 1 2450

https://www.mouser.co.uk/ProductDetail/495-TSN1-2450/

That would eliminate the need for a heat sink inside the Atmos, you will need to increase the 1uf Capacitor to around 10uf to delay the startup as the TSN is slower to start compared to the LM7905.
I have done my Atmos and it was trial and error finding the right value for the capacitor - your mileage may vary.

 

Great result, Graham.

Hope you have many happy hours with the old fruit!

Richie, as ever, thank you for assisting in this repair and we have one new happy Oric user!

Thanks, Graham.

Very kind to look over the microdisc to see what you can do.

No rush as ever.

 

If @Graham can figure out how to align the head on that model of 3” drive it should be salvageable. I’m pretty sure that is what is wrong with it as the logic board is fine and the 3” drive works up to the point where it looks for track zero on a 3” disk.

 

@Graham regards the Oric PSU it is known that the PSU unloaded outputs 11v-15v but when under load drops to around 9v so I would say your PSU is an “average” Oric power supply, if it’s an official Tangerine one. It’s one of the reasons the Oric heatsink gets so hot toot sweet.
The replacement of the Voltage Regulator on the Oric for a modern type means a couple of things related to above the most obvious is the heatsink being no longer needed, and the complete lack of heat from the VR. It also runs more efficiently as well.

I should mention that you can get a horizontal mounted model of the new VR ( TSN-1-2450A )this is the one I use.

 

Many thanks, Richie.

I know you put a fair bit of time in there doing all you could to sort the 3" drive reading and then ran up against the head alignment issue.

Hope those pointers help you, Graham.

Many thanks, fellas - bit busy at mo this end as Bev has her pot off now (discharged from hossie on Thursday) so spending even more time now guiding her around as she tries to get (gingerly) back on her feet but needs escorting in case of a fall/collision as she's next needing weeks of physio.

 

Glad she has the cast off, I hope she gets past the fear of another fall asap...

 

Many thanks, Paul.

Although the healing and mending has gone ever so well (she has a 6inch plate inside with 2 fek off long screws she was proud to tell me about), it aches like buggery for her and I've caught her bad leg twice already stupidly thinking she's back to normal now... clearly isn't from the verbals I got for being so clumsy!!!

The air was BLUE, folks!

LOL.

 

I know that one,, because of my knee's and the constant worry of a collapse of the knee's I'm paranoid about people being behind me as if they catch my feet by accident I go down like a sack of spuds and getting back up is very painful. Sadly Cindy has a habit of wandering behind me and not realising how close she is and trips me up on the odd occasion....Its one of the very rare times I get annoyed with her and the air is indeed blue..

Its not deliberate, in fact she's trying to stay close in case I fall..

 

That's great news about Bev... I'm sure I can speak for us all in wishing her a speedy recovery back to normal.

As you may have realised my post code is one that's affected by the South African varient of Covid. very strange to me knowing our local area and its inhabitents and we are between two larger Urban area's .. Good news (maybe) is that we can get tested every 10 days even if not showing any symptoms, so may catch it much earlier if we do become infected in some way ( really can only be Pam's children she looks after) I've had to cut off visiting Mum, puts the onus on my sister.

It's also given me a little more time to try and tidy my workshop.. well thats what I thought anyway.
That and Ian from 'retro computers' was on holiday the whole of Jan, and I was to lazy to make my own video cable..

@Vyper68 Thank you for the heads up on the negative rail voltage regulators, last time I searched for something similar were over £20 pound, nearer £10 now. good to know about the reset circuit capacitor as well.
@Andy Barr if you havn't had one fitted by Richie ... it's something I'd recomend to any oric owner. & works exactly the same way as the two regulators I replaced in the microdrive...

Last thing for this morning, the XEGS I'm building is now running. used a XEGS MMU & an EPROM ,, not sure why the U1MB boards not working, as installed correctly and are pretested in other computers, but that was all thats wrong.
if peeps need any MMU'S either XL/XE or XEGS I know I can now program these

 

I TOTALLY get that, Paul. Understood, mate.

When we've had to travel inbetween the house, the car and the hospital, Bev's insisted on me being behind her just in case her crutches slip in the wet mud or ice (goes from one extreme to another in 'Ull), and she topples backwards as this is her greatest fear.

I just need to be more wary of catching her leg/foot thinking she's all mended now.

She aint - it was a very nasty set of fractures and the docs have said she has done brilliant to heal as well as she has done as they were on the verge of putting a steel cage around the shattered leg, it was that bad initially.

Sorry to hear of your ongoing pain and as you know and appreciate, Cindy's showing her care and concern and when they get it a little wrong, we do tend to bawl out at the one's we love the most due to the painful shock (then instantly regret it!)

Take great care, fella and hope to have an online catch-up soon with you guys.

 

@Paul "Mclaneinc" Irvine I think we all make the occational mistake and end up hurting our parteners whilst trying to help., It's sometimes difficult to be helpfull without getting in the way .. and hey blue air ... better than covid air ..

 

@M.D.Baker
I think I've found away of turning something like these :- https://uk.banggood.com/Geekcreit-E...MIi-2x6JvV7gIVWPhRCh0ZHw5pEAQYAyABEgL6ZPD_BwE
and replacing the modual with one of these
https://www.digikey.co.uk/product-d...16MB/1965-ESP32-WROVER-IE-16MB-CT-ND/11613179
a few small capacitors to change plus a daughter board with three leds buttons and a few 74ls07 buffers two fets and some resistors..
into a fuji net.

This will save me having to try and solder this https://www.digikey.co.uk/product-detail/en/silicon-labs/CP2102N-A02-GQFN24/336-5887-ND/9863476
it has 6 legs on each side and is 4mm square they do one thats 3mm square and stopped production of the larger varients

 

Isn't it all the same now Graham

I'm normally anything for an easy life despite the depression and the pains, fighting with your own head is hard enough as it is, fighting with others, too much of a bother that one..

 

The Brewing Academy FujiNet devices are using the slightly older ESP32-WROVER-B module I think the IE variation is the more modern replacement part. The v1.0 version I have seems to work just fine but it will be interesting to see what you come up with as far as PCB design goes.
I have ordered some Quad-OS PCB’s if you want a couple.

 

@Vyper68 I've a fair number of bit's I'll be sending off to you I've been waiting for some edge connectors to come in to make up a cable. Will be MX mother board, and ribbon to connect it, and a few plug in boards and odds and sod's
mainly for those boards. not sure how much use they will be to you, But I know the 464 has made it back to you. Did you ever get an M4 board off of Duke ?

In regard the Fujinet, there are many ESP32 boards available but most don't have the larger capacity modules attached. at the moment they are making use of the 8MB + 8MB modules but future software may need more room. hence specifying the 16MB version
Comparing the schmatics for the boards about the size of a long Arduino Nano, they are very very similar, with additions for a few extra buttons and LEDs and an mSD card socket. There is a slight variance on some capacitor values on the boards, but looks like the Fujinet 1.0 uses the basic schematic, the 1.3 adds two fets and two '07' buffers to disconnect all the SIO lines. issues with back feeding power under some circumstances.
I'll use a module, change the ESP to a higher spec version, and build a small board to connect to sio with the extra buttons leds, and buffers required.
Any suggestion would be welcome. I did seriously think of buying in the individual components to build from scratch, but I think the cp2102's will beat me soldering wise, although I could try with the hot air gun and solder paste.
the CP2102 is out of stock on digikey at the moment even the 20 pin 3mm square ones and the larger 5mm square The 6 & 7mm square all out of production.
Be nice to do something joint between us what do you think ?
