Yep, Aliexpress is around $32 for a Basic model, I'm using the Discovery and Enhanced models. The Enhanced one has a RTC... I bought a Discovery and Enhanced model from Ali, but be warned, they use piggyship and are the worst carrier. They through the package out of a car window an into the gutter... Had 2 Enhanced models sent yesterday from Amazon for $48 each...

After looking at my code, I wasn't either, but will definitely add that. Thanks, it's a great idea 👍...

Here is the Next Generation of upgrades for SIO2WiFi, WifiModem and FujiNet This is my next update that will be using the Nextion Displays that will allow you to setup your WiFi Access and configure many settings All though the use of a Touch Screen... You Saw It Here FIRST

Oh no! not these too Lets see, 3 830's 3 835's, 4 1030's 2 SX212's and some MPP/Supra modems too...

The reason why I have over 20 drives was due to my cart collecting. Had to buy whole systems at times just to buy the Rare carts. (320 individual, 615 total) It is an addiction

Only 8? That's just the start I have over 20 (810's, 1050's, XF551's, Indus GT's, Rana's, Trak's and "the big bulky ones") ...

Picked up some chips to restore some 800xl's that I took parts out of to build the 1088XLE and 1088XLD'S...

ATR Tools?

In order to get FNET working with FXEP with real HW or Altirra over the internet, you would need to make a TCP Bridge/Gateway/Proxy that understands the FNET protocol...

------------------------------------------------------------------------- DOS XE maximum file extent of 1500 clusters, or 375000 bytes (366.2 KB). Max # of Files Per Disk: 65535 Max # of Files Per Directory: 1250 Max # of Clusters: 65535 Max # of Chars in a Pathname: 80 "D1>PROGRAMS>BASIC>PROGRAM1.BAS" >>Boot Sector: Byte: Desc: $00 - "X" Representing DOS XE $09 - number of files possible to open at a time. Default 3, max. 7. $0A - a bitmap of active drives: bits 76543210 correspond to drives 12345678. A bit set to 1 means that the corresponding drive is active. $0B - $00 $0C-$0D - Buffer Base Address. $0E-$0F - Date Code when DOS Was Written. $10-$15 - an ASCII string, up to 6 characters, padded with zeros, if shorter, symbolizing the density (or disk type): - AT810 - single density - AT1050 - medium density - SSDD - single sided double density (180k) - XF551 - double sided double density (360k) - 130RAM - 130XE ramdisk $16 - 0x01 NOT Number of VTOC Clusters on Disk. $17 - 0x01 ???. $18-$19 - total number of clusters on the disk, (Plus 1). $1A-$1B - initial number of free clusters on the disk $1C - First Byte of VTOC. $1D - number of the first cluster of the main directory $1E-$1F - SIO Routine Address. $22 - SIO command "Read sector", "R" for standard, "R"+$80 for XF551 fast mode. $23 - SIO command "Write sector", "W" for standard etc. $24 - Pokey's AUDF3/4 value to generate the command baud rate, $00 for standard, $28 for XF551 fast mode. $25 - Pokey's AUDF3/4 value to generate the data baud rate, $00 for standard, $10 for XF551 fast mode. $26 - SIO command "Format disk" for this disk type, "!" for standard interleave, "!"+$80 for turbo interleave. If the disk does not need formatting (ramdisks etc.), $00. $28-$2f - first 8 bytes of the PERCOM block defining the disk parameters (number of tracks, sectors per track, sector size etc.) >>VTOC: ---- The VTOC is held in the cluster 4 (sector 4 in DD, sectors 8-9 in SD and ED). In the first 10 bytes there is disk information as follows: $00-$01 - value $0101, format magic/version number? $02-$03 - total number of clusters on disk, (Plus 1). $04-$05 - number of currently free clusters $06-$07 - number of files and directories on the disk (= volume sequrntial number), intially $0000 $08-$09 - volume random number The further part of the VTOC, from byte $0a onwards, is occupied by the bitmap. If a bit is set to 1, it means that the corresponding cluster is free, or it is in use otherwise. Bit 7 of each byte is assigned to a cluster of a lower number, and the subsequent bits of the byte correspond to subsequent clusters. The cluster 0 has no corresponding bit in the bitmap, bit 7 of the first byte in the bitmap (byte $0a of VTOC) corresponds to cluster 1, bit 6 - to cluster 2, bit 5 - to cluster 3 etc. Initially the first free cluster of the disk is cluster 6, and the first byte of the bitmap has a value of %00000111 (clusters 1-5 in use, 6-8 free). >>Directories: ----------- The main directory begins right after the VTOC, and initially occupies only one cluster. Its number is indicated by the byte $1d of the bootsector. A single direcotry entry consists of 49 bytes: $00 - status byte: - bit 7 = 1, file deleted - bit 6 = 1, file in use. In closed files bit 7 and 6 always have opposite values. - bit 5 - unused - bit 4 - unused - bit 3 - unused - bit 2 = 1, the file is open for write. Bits 7 and 6 are simultaneously set to 1. - bit 1 = 1, file protected - bit 0 = 1, subdirectory $01-$08 - file name padded with spaces, if necessary $09-$0b - file name extension padded with spaces $0c-$0d - number of data clusters occupied by the file. $0000 for a dir. $0e - number of data bytes in the last cluster of the file. $00 for a dir. $0f-$10 - global file number (volume sequential number at the time when the file or dir was created, plus 1). $11-$12 - volume random number (same as in VTOC) $13-$14 - dir: number of the first cluster of the directory data file: number of the first cluster of the file map $15-$2a - dir: 22 zeros file: 11 numbers of subsequent cluster of the file map ($0000 - unassigned) $2b-$2c - file creation date: - bits 0-4 day of month - bits 5-8 month ($01 = January etc.) - bits 9-15 year-1900 $2d-$2e - file modification date (same format as above) $2f-$30 - unknown bytes (always zeroed) Every newly created file gets status $c4. After the file is closed, bits 7 and 2 of this value are zeroed. Directory data clusters ----------------------- Each cluster of the directory always contains a integer number of directory entries, maximum 5. If the directory has more entries, the 6th entry is stored to a next cluster of the directory etc. Bytes: $f5-$f7 - unused and the last 8 bytes ($f8-$ff) contain information about the directory: $f8-$f9 - number of the next cluster of the directory ($0000 - last one) $fa-$fb - global file number ($0000 - main directory) $fc-$fd - volume random number (same as in VTOC) $fe - directory chain cluster number (starting from $00) $ff - cluster type ($ff = directory) Files: ----- The file map The file map consists of clusters indicated by the bytes $13-$2a of the directory entry. The first 250 bytes of the map's cluster contain up to 125 numbers of data clusters allocated for the file. The last six bytes contains additional information: $fa-$fb - global file number $fc-$fd - volume random number (same as in VTOC) $fe - map's cluster number in the current file (starting from $00) $ff - cluster type ($80 - file map) The directory entry provides 24 bytes for the list of the map clusters. Because the cluster number is 16-bit, the file map may extend to max.12 clusters. 12 clusters * 125 data entries * 250 bytes (see below) results in the maximum file extent of 1500 clusters, or 375000 bytes (366.2 KB). If there isn't any other method of linking longer files, this is the ultimate file length limit in this file system. Data clusters Each data cluster contains up to 250 bytes of data. The last six bytes contain additional information: $fa-$fb - global file number $fc-$fd - volume random number (same as in VTOC) $fe-$ff - the number of the data cluster in the current file (starting from $0000) The maximum "number of data cluster" is 32767. The higher byte is always a positive value and thus forms the cluster type mark (<= $7f = data cluster). Sector Label Byte Description 1-2 File ID Number 3-4 Volume Number 5-6 If Byte #6=255($FF), it is a Directory Sector and Byte #5 is a Sequence Number* within the Directory. If Byte #6 is between 128($80) and 254($FE) then Byte #5 is the Sequence Number* of a File Map Sector. If Byte #6 is 127($7F) or less, Bytes #5 and #6 form a Standard 6502 WORD-Sized Sequence Number*. * The Sequence Number indicates the Relative Position of that Sector within it's Series (That is, 3rd Directory, Sector, 2nd File Map Sector, 75th Data Sector and So On.). -------------------------------------------------------------------------

Why would you use Telnet ? Better choice is to use RAW TCP...

My PCBWay orders arrived I had 5 of the VBXE 800 Carrier Boards Assembled so I'll have three to sell if someone else is thinking of adding VBXE to their 800. Also had some SIO2Wifi boards made, have a new HW addition to add to these

@candle @flashjazzcat PCBWay is now asking for clarification of the two electrolytic caps and the oscillator's orientation on these. Could you shed some light on this? Thanks, Jay

Which program are you using to update the firmware? Okay, I see... The fujinet official flasher... Nevermind :)

Thank you

@candle and @flashjazzcat I'm having PCBway build a couple of the VBXE 800 Carrier Boards and assembled and they are asking about a pic-n-place file. Do you know if it's included in the VbxeSlot3Carrier-cam.zip file? or if it exists? Thanks, Jay

Does anyone have 1 or 2 of these and built/tested and ready to sell??? I was going to order the pc'b, but noticed it has smd's. And when I went to checkout the comments on shippers basically say must are unreliable or some other reason not to use...

Yep, SchoolGirl*** and Atari8bitcarts willl probably toss in their $500+ bid in the last 20 seconds...

Mine had 2 PLCC sockets right on the PCB.

Okay, so probably PAL. The one I'm referring to are NTSC, so yours may be ok then...

They're also used in the U1MB's and Incognito. @bf2k+ My old Willem read/write these perfectly

Yep, the 800xl I took it out of worked great, but not in the 1088xld and if used in conjunction with a Sophia 2 all you get is a screen full of garbage. Sophia 2's love the -37 version of Antic...

Check for hairline shorts between IC Pins or other parts that mount close to the really small Vias. Clean the Bottom side thoroughly... I first scrub the flux off with 99% Alcohol (with a toothbrush) then repeat using Windex (Glass Cleaner) and finally clean using hand soap and hot water. The end result is a very clean PCB. Now use a Bright Light and Magnifying Glass and check for shorts again... What is the FULL part number of your Antic Chip, if it ends with "-01" then toss it and replace with a "-37" version... Besides the "No VBXE" Jumper, what other Jumpers do you have in place?

Tests ok with WinZip...

Looks like the dithering gave her a fat lower lip...
