Hello all, I try to merge all schematics of ATARI IDE IF V2 & Flash TOS x4 from http://atari.8bitchip.info/astams.php My idea is create PCB with flash memory for reduce the wiring. I delete the part 6 ROMs, not need if i place 2 x ROM on PCB (it seems logical to me) But i see on ATARI ST IDE IF....
Hi, I have ordered this monitor this week and recieved. Works on all ST Resolution with adaptor: http://www.atari-forum.com/viewtopic.php?f=15&t=30521 https://www.befr.ebay.be/itm/NEC-LCD1970NXp-19-1280-x-1024-250-cd-m-20ms-VGA-DVI-Schwarz-Silber-TCO03/302619863442?ssPageName=STRK%3AMEBIDX%3AIT&...
Forget this post. I have installed the 3.6 of GFA, now all works. This morning, i have sometime crash of 3,5 GFA with CE_DD enabled or microCosmos connected. Is not problem of CE_DD.
Hi, I have recieved FRAK-2 PCB, but the PCB as not printed overlay on both side and manual is not up to date. I have create the overlay with PCB on back ground and BOM for easy assembling FRAK-2: FRAK-2-TOP OVERLAY.jpg FRAK-2-BOTTOM-OVERLAY.jpg For BOM and More quality you can download here: http://...
Hi Foxie, Replay 16, as special IC (programmed) and not part number writed on IC. Is search Replay pro, but is very rare. I use this service for stencil https://jlcpcb.com/ for 9$ the stencil is stainless steel, for 290x190mm valid area. I can place multiple design on stencil. Others size aviable ea...
Hi, I create many PCB in SMD (http://www.gossuin.be) in small quantity. I use stencil and oven (size 10x10cm) for soldering, the stencil is low cost 9$. I limit the size at 0805, for ic i have not limit but not BGA, but is more easy is the chip is soic or tssop. But is PCB as components in both size...
I use Da Vinci 1.0A from XYZprinting. It's plug and play printer, no time to loose for assembly the printer. It's not perfect printer, but a this price is good. Just the price of ABS cartridge, but sometime i found at lower price. My brother as Ultimaker 3, the printing is very more good, but the pr...
There will be a new batch soon (but now is the Chinese new year) The Floppy is powered from external power supply. DB9 would be nice, but those are on keyboard and would need long wire... It could be splitted from the keyboard connector, but that needs crimping connectors and splitters and stuff --...
today i have recieved the monitor DELL U2412Mc, i have other forum works in 15khz. It's true, now i can display the medium and low resolution with the switch:
U2412Mc color.jpg
but the monochrome not supported (OSD message), it's first monitor not accept
Hi, I found why i have many problem of stability. The 12V on DIN 13 it's very limited in current, in schematic of 1040STE the 12V is in serial with 1.2K resistor, the max current is 12/1200 = 10mA. With led, the current is to big. I have started this project because the assembly cable on web (eBay) ...
I have found this list for 'modern' VGA 15khz: http://15khz.wikidot.com/ but, i have launch research in distributor monitor =>17" max price 200 euro end user. Not exist, i have check over 200 monitors type/model. the minimum is 24Khz. Now the solution is use scan doubler. Any use this solution ...
I'm stupid, I do not check the regulator's sense. With the 7805 (TO220) the input is on the left, with 78L05 SOT89 it is reversed. (The manufacturers do not simplify our life).
I have only 3V, probably the AVR not write in eeprom at this voltage.
Small list of monitors color resolution not works (only monochrome works): Viewsonic VG712s Viewsonic Vx924 Viewsonic VG721m Viewsonic VG930m Viewsonic VA903m Samsung SyncMaster 910n Philips Brilliance 220SW iiYama Prolite H430
I have not burn bootloader, i use avrstudio & atmel ice with ISP for programming. The epot is not connected at the AVR, the current is 0,75uA at Max 3,5uA, is very low. For the Led i have used 470R = +/- 6mA, only one led is enabled. In the code added this: #define monochromeLed PB3 #define colo...
