KG4LNE has a great solution coming for those pesky eproms. Check out the link below. I have 3 radios ready to use it when it is complete.

Re: [Repeater-Builder] KC5EVE s GE Phoenix Programmer
Ok, I see what is going on. Life is going to be alot easier on you if you have a way to detect fast logic level changes, but if you do not there are a few simple parallel port debug programs out there on the market. http://neil.fraser.name/software/lpt/ I will assume you are using the VO1CPU version of the schematic as that is the one that seems to make the most sense to me. 0. Pull the chips out of the sockets 1. Verify connection between DB-25 Pin 1, 74HCT373 Pins 1 and 11, and X2212 Pin 11 1a. Inspect for adjacent pin shorts (solder splashing ocassionaly happens right under the sockets). 2. Verify that pin 1 is high for the LPT port 3. Run the program downloaded from above and toggle pin 1 (strobe) to a low condition 3a. High should be approx 5Volts and low should be anything below .8V (Usually .0V) 4. Verify that the proper drives are present from the computers port. 5. Insert 74HCT373 and verify write enable drive levels again. 6. Insert X2212 and verify write enable drive levels again. Chances are your LPT port doesn't have enough fan-out and cannot drive both chips. In theory pin 1 from the DB-25 should go low, which when that happens will latch the data in the 74HCT373 and turn on the output drivers to give D0-D3 from the computer to the chip and command the X2212 to write.

Checked out the KG4LNE Link. Looks really professional.

Re: [Repeater-Builder] KC5EVE s GE Phoenix Programmer
I could use some advice from someone who has built one of these types of programmers. I put one together on on a perfboard and cannot get it to write to an eprom. It can read just fine. Pins 111 of the '373 latch chip are pulled high all the time and I'm not sure if this is correct. Have checked my wiring several times; no mistakes. Have tried powering from a 9V battery as well as from a wall wart (both using a 5V regulator of course) Have also tried different latch chips and different computers. Have tried different X2212s. Has anyone been down this road before and would be willing to give some advice? For such a simple schemo, this thing sure is a bear to make work. TIA 73 Paul - Original Message - From: bzlljr Has anyone had success in getting the IC Chip 74HCT373 or 4 for the project Mark came up with. Have sent Mark e-mail to see where he got it.
