            "content_html": "<figure class=\"post__image\">I've prototyped a simple interface for a usb flash drive to a microbee.<br>It uses a CH376 interface board (about ~$5-$10 on aliexpress) and connects to the data bus of a bee and a few signals with 14 wires. I'm currently running a freebee cf coreboard and have it plugged into the (for me) unused ide interface with the addition of a couple of links.<br>I snaffled the software from the romwbw project and modified it for the ch376 chip. (it originally came from <a href=\"https://github.com/wwarthen/FAT\">https://github.com/wwarthen/FAT</a>)<br>The usb flash drive is formatted to fat32 and I can r/w on windoze then plug it into my bee and copy files to/from fat32 on the flash drive to cpm format on my cf.<br>I still need to clean it up and write up the connections. The code needs a little polishing and hopefully it will allow hotplug of the usb flash drive when I've finished.<br>Others have used the same ch376 chip for mouse and keyboard interfacing, so there is some potential there.<br>It is using lba mode to address the usb drive so, with some changes to the bootrom and bios in theory it would be possible to boot from a usb flash drive.<br><br>Currently I'm using the cpmtools on linux to r/w directly to the cpm formatted cf drive to transfer files. This is, hopefully, one step less in the process.<br>More to come!<br><br><br>there is two models of the ch376 interface board, one with a 3 pin header and one with a 6 pin header. I'm using the 3 pin header at the moment but have a 6 pin on order. As far as I can work out, apart from the 3/6 pin the other difference is in the dual row header where one has the data lines facing in and the other has them on the edge of the board. Functionally I believe they are the same. They use the same chip. If you were laying out a pcb to interface I've seen one version where a triple row header was used and you just plug the board one side or the other. It'll make sense when you see the boards.<br>I'm chasing a bug that the first access to the flash drive fails but the second and subsequent work fine. I've added rtc for the writes to fat. But I'll need some logic to make sure it still works with no rtc fitted.<br>I've found that you can hot plug the flash drive to the ch376 board but I'll look at adding a 'dismount' function or simply turning the power off the flash drive after access. There's a led on the interface board and I'm assuming that it comes on with power. <br>Hardest part so far has been fighting with the build systems. I initially tried to port the original code to compile under Hitech C but it got to hard when I had issue with the underlying FatFs code needing to many changes. So I moved to using SDCC as per romwbw project does and that was another experience.

Without the RTC code any file copied to the usb flash drive from the bee would have a generic timestamp, by adding the code to read the bee's rtc it now displays the copy time similar to windoze/linux does.<br><br>I'm using a subset of the ch376 functionality. It supports some fat functions directly but I'm using it in 'block' mode with the FatFs software providing the FAT interface. There is a series of the chips with increasing functionality and theoretically the ch375 should work as it also supports the block mode. That said one site https://github.com/djuseeq/Ch376msc has reported different firmware versions of the ch376 having differing success. From what I can gather I have an older version of the chip on a 3 pin header board with a sandisk 32g flash drive on it and it appears to be working fine. I have another board on order with the 6 pin header so I'll check that as well. The web site quoted appears to use the ch376 in it's inbuilt fat support while I'm not. So his comments may be not relevant.<br>They are pretty cheap though.<br><br>Looks like I won't be testing the alternate ch376 board anytime soon. Supplier has shipped the completely incorrect item twice now.<br>fwiw my bee now has ~65GB of storage, cf 1GB, usb flash in gotek 32GB and usb flash on ch376 32Gb. I may have to find some different projects.<br><br>Reading from USB flash and writing to CF ~ 5 times faster than reading from USB flash and writing to gotek.<br>Reading from usb flash and writing to m drive marginally faster than writing to cf. However the transfer to/from FAT isn't optimised. It only reads a single sector at a time and then copies to cpm which has to squeeze that through 8 x 128 byte cpm sectors onto the storage medium. Without delving into cpm bdos/bios internals I think this means a factor of 8 multiplied sector writes to achieve. <br>I've been making a backup of my CF to the usb flash drive and updated my cf image (new ram arrived) then restored from usb flash. Makes updating and transferring files much easier and quicker. Probably an opportunity to make some submit files to semi automate the backup.<br><br>I haven't had a chance to try the '6 pin' module, they shipped incorrect modules to me. The extra 3 pins are used for a serial interface which I'm not using and the other difference is the '3 pin' module has a connection for reset which I'm also not using. the reset is active high rather than the bee's active low reset. The adapter board powers up fine with the circuity on the adapter so I've just left it o/c on mine. <br>The circuit for the '6 pin' is here <a href=\"https://zerowincoding.tistory.com/entry/CH376S-Arudino-Disk-Read-write-Module-USB-Flash-Disk\">https://zerowincoding.tistory.com/entry/CH376S-Arudino-Disk-Read-write-Module-USB-Flash-Disk</a> note the 0.47uF on the reset pin. I haven't found a cct for the '3 pin' version. My translation of the device spec sheet has the reset input with an internal pull down.<br><br>I've not had any issues requiring a power on reset so far. I have also hot plugged and unplugged the flash drive and it has worked without any noticeable issues.</p>\n<p>Software and source code for the <a href=\"https://sages.com.au/rodshed/media/files/FAT-master-2.rar\">FAT program</a> and some floppy images with a copy of the run time program (FAT2.COM, I renamed if for some reason) <a href=\"https://sages.com.au/rodshed/media/files/cfbios.rar\">here</a>.</p>\n<p><br>And that’s about all I wrote up about the project.</p>\n<p>addendum</p>\n<p>And I found this sub file I knocked up<br><br>Backup.sub<br><br>user $2<br>fat copy $1:*.* 0:/$1$2<br><br>usage: ss  backup.sub [src drive] [src user]<br><br>It backs up all files on src drive user to the usb drive on /src driveuser, ss backup.sub a 3, all files from cpm a3 end up on the cf in folder /a3<br>(ss -&gt; actually supersub)<br><br>Easy to backup all of your cf drive</p>\n<p> </p>",

The cost of parts (mainly freight) to repair my very reliable vintage Stihl 015AV saw made the Chinese saws look attractive.</p>\n<p><!-- /wp:paragraph --></p>\n<p><!-- wp:paragraph --></p>\n<p>I went all out and purchased the mighty X-Bull 75cc chainsaw. A bit of a delay due to the efforts of Australia Post but the day finally arrived when my new toy had arrived. After some minor issues with assembly (the chain brake was activated and a bugger to release) I was all set to fire it up. Choke, couple of pumps of the fuel bowl thingy, gentle pull on the starter and within a couple of pulls the first firing occurred. Opened the choke, another pull and off it went. You beauty. Idles, revs, chain spins, oiler works. Just like a real one.</p>\n<p><!-- /wp:paragraph --></p>\n<p><!-- wp:paragraph --></p>\n<p>Given the earlier research online I was anticipating some QA issues, a general cheapness in build and potentially some reliability issues but time will tell. One aspect that I had seen several mentions of was the poetic license regarding the actual capacity of the chainsaw.</p>\n<p><!-- /wp:paragraph --></p>\n<p><!-- wp:paragraph --></p>\n<p>This I had to check. So spark plug removed, muffler removed, calipers in hand, measurements began.</p>\n<p><!-- /wp:paragraph --></p>\n<p><!-- wp:paragraph --></p>\n<p>Hmmm, bore 46mm, stroke 34mm, quick remembering of secondary school maths and we end up with near enough to 56cc displacement. Bit of a difference. Double check measurements and calculation, nope still end up with 56cc.</p>\n<p><!-- /wp:paragraph --></p>\n<p><!-- wp:paragraph --></p>\n<p>Contacted the vendor with this issue and they wanted photos. Bugger, I'd reassembled the chainsaw. Pulled the relevant bits off it again and photographed the measurement process (riveting stuff looking at a series of vernier caliper measurements, I declined to photograph the calculation). Vendor was now off to contact the factory. Never heard of it they said.Someone must have put the wrong chainsaw into the box was the claim (picture large bovine testicles). We have no more in stock said the vendor (apart from three ads still online all claiming stock levels &gt; 10). Please send it back, vendor offers to pay freight, and we'll refund you the full purchase price.</p>\n<p><!-- /wp:paragraph --></p>\n<p><!-- wp:paragraph --></p>\n<p>OK, I'm a little peeved that after waiting for so long to get my purchase it wasn't what was advertised and I can make up my own stories so their explanations weren't a bonus and a full refund was pretty fair.</p>\n<p><!-- /wp:paragraph --></p>\n<p><!-- wp:paragraph --></p>\n<p>Bit of a hiccup with the return process, I'd started the chainsaw, even if I drained the fuel and oil I'd have to somehow arrange for all traces of the fuel to be cleaned before it could be shipped legally. Fuel and oil are considered dangerous goods according to Australia Post and a couple of freight companies I contacted.</p>\n<p><!-- /wp:paragraph --></p>\n<p><!-- wp:paragraph --></p>\n<p>Back to the vendor with the shipping problem. I was asked if I would accept the chainsaw, with it's undersized displacement as well as a partial refund. After some pondering, I decided to accept the partial refund and the chainsaw.</p>\n<p><!-- /wp:paragraph --></p>\n<p><!-- wp:paragraph --></p>\n<p><strong>Observations:</strong><br><br>The vendor essentially responded in a positive manner with regard to the issues. I'm pretty much not convinced that the vendor ran out of stock or someone put the wrong chainsaw into the box. That if I selected any other of the chainsaws they were selling that I wouldn't find exactly the same thing regarding incorrect displacement.</p>\n<p><!-- /wp:paragraph --></p>\n<p><!-- wp:paragraph --></p>\n<p>Yes, it's a cheap chainsaw. Did I really need a larger capacity chainsaw? Not really but bigger is better right? Is it good enough for what I want? Time will tell. (I haven't named the vendor as I feel it's academic, the issue is with the factory(s)). Be aware of the potential problem, ie buyer beware.</p>\n<p><!-- /wp:paragraph --></p>\n<p><!-- wp:paragraph --></p>\n<p><!-- /wp:paragraph --></p>",

But all is now good again.</p>\n<p>My 8 (new) 41256 dram chips arrived so I added them to the core board as per the 512k upgrade instructions by Peter Broughton. I did get caught out a little bit as the floppy drive died in the middle of all of this, my ancient eyes and shaking hand produced a dry joint ( solder ) and the PAL on the coreboard was from a CIAB which didn't support dual dram banks. I had made a variation on the 512k upgrade way back in the '80s that compnesated for this but only for a single dram bank up to 256k. So luckily the other coreboard I had was complete with the required PAL.</p>\n<p>I've also completed the 6.7 MHz speed mod.</p>\n<p>I decided to try and use the PJB system along with the IDE/CF bootroms and bios code modified by Kalvis Dukmanton as a base. So I've now switched from my original code, bios and boot roms to this.</p>\n<p>The bootrom is ok as is for the moment but it, along with the bios, will need a little tweak as my CF mod uses the 8 bit data xfer mode rather than the traditional 16 data mode.</p>\n<p>I'm just working through the h/w interface ( physical side of things ) for a CF ( only ) ide adaptor and a few of the s/w things.</p>\n<p>Keeping with the simple and cheap as possible theme, i'm using a ide to cf adaptor from ebay, some standard 40 pin ide cable from a PC, some vero board and some single row header. It should all fit onto a 128k coreboard ( 8342 ).</p>\n<p>Bare board where the header will be fitted.</p>\n<figure class=\"aligncenter size-medium wp-image-93\"><a href=\"http://westnet.net.au/sages/IMG_1500.jpg\"><img loading=\"lazy\"  title=\"IMG_1500\" src=\"https://sages.com.au/rodshed/media/posts/10/IMG_1500-300x225.jpg\" alt=\"\" width=\"300\" height=\"225\" sizes=\"(max-width: 1920px) 100vw, 1920px\" srcset=\"https://sages.com.au/rodshed/media/posts/10/responsive/IMG_1500-300x225-xs.jpg 640w ,https://sages.com.au/rodshed/media/posts/10/responsive/IMG_1500-300x225-sm.jpg 768w ,https://sages.com.au/rodshed/media/posts/10/responsive/IMG_1500-300x225-md.jpg 1024w ,https://sages.com.au/rodshed/media/posts/10/responsive/IMG_1500-300x225-lg.jpg 1366w ,https://sages.com.au/rodshed/media/posts/10/responsive/IMG_1500-300x225-xl.jpg 1600w ,https://sages.com.au/rodshed/media/posts/10/responsive/IMG_1500-300x225-2xl.jpg 1920w\"></figure></a></p>\n<p>Right angle header, left hand end will have small piece of vero board with extra pins to pick up pins 36, 38 &amp; 40, gnd and maybe +5v that are on the other row next to the 34 pin connector.</p>\n<figure class=\"aligncenter size-medium wp-image-94\"><a href=\"http://westnet.net.au/sages/IMG_1501.jpg\"><img loading=\"lazy\"  title=\"IMG_1501\" src=\"https://sages.com.au/rodshed/media/posts/10/IMG_1501-300x225.jpg\" alt=\"\" width=\"300\" height=\"225\" sizes=\"(max-width: 1920px) 100vw, 1920px\" srcset=\"https://sages.com.au/rodshed/media/posts/10/responsive/IMG_1501-300x225-xs.jpg 640w ,https://sages.com.au/rodshed/media/posts/10/responsive/IMG_1501-300x225-sm.jpg 768w ,https://sages.com.au/rodshed/media/posts/10/responsive/IMG_1501-300x225-md.jpg 1024w ,https://sages.com.au/rodshed/media/posts/10/responsive/IMG_1501-300x225-lg.jpg 1366w ,https://sages.com.au/rodshed/media/posts/10/responsive/IMG_1501-300x225-xl.jpg 1600w ,https://sages.com.au/rodshed/media/posts/10/responsive/IMG_1501-300x225-2xl.jpg 1920w\"></figure></a></p>\n<p>Right angle socket under vero board, just visible at left. vero board needs to be this short so that it clears the FDC to allow it to be unplugged.
