Hello Folks ! The first part of the project, will make a Test Pattern, once the RS232 does not have enough speed to make a the Speed Test. Most of SRAM memories fail at this point... It consists on fill all addresses with 0s, 1s and pattern like 0000000000 0000000001 0000000010 0000000100 0000001000 0000010000 0000100000 0001000000 0010000000 0100000000 1000000000 0100000000 0010000000 0001000000 0000100000 0000010000 0000001000 0000000100 0000000010 0000000001 And repeat at inverse way (0s in place os 1s and 1s in place of 0s) The second part of the project, I'm planning to make on clock circuit (up to 20MHz) to make the Speed Test, filling all addresses with 0s and another test filling with 1s. The software control, will be another important part of this project. I hope to share experiences with you guys, and ALL comments will be very welcome !!! I'm studing PIC microcontroles, and soon I hope to have one PCless tester :) Thank you JosÈ Luiz Martins De:"joemagiera" Para: CÛpia: Data:Mon, 29 Dec 2003 17:11:04 -0600 Assunto:RE: Parallel Port Ram Tester from Brazil! > Hi Luiz, > > Welcome to our list!

Parallel Port Ram Tester from Brazil!
by John Robertson 29 Dec '03

29 Dec '03

One of our new members (Luiz) was attempting to post a note on a project of his, but it was too long (embedded JPG) and I think he might be on vacation (or something) so I'll edit and post it for him...(I've put his schematics in their own folder on the ftp site (RamTester)). Unfortunately I have been unable to extract the JPG from his huge post...hoping he'll send it to me! John :-#)# -----------------------(original)----------------------------------------------- Hello Folk! I decide to start building one PC (Parallel port) Based SRAM Tester, after some attempts to use old tester on fast PCs with no success, and due to prohibitive prices of modern one. For me, in Brazil, it costs about 2,000 Dollars !!!! The first part of this project is a simple 2114 Tester, and the next step will be accept 5101, 4116, 6116 and finally 6281. My target is build one TTL and CMOS Tester as well. I'll share with you guys this project, and I'll be very glad to hear suggestions and answer all your questions. Attached, you are receiving it's schematics, and this weekend I'll write it's code. I did this project as simple as possible, using one CD4040 (12 binary Counter) to generate the address line, one 74LS245 (Octal Bus Transceiver) as data buffer and to protect the PC's RS232 port. Thank you for your time reading this e-mail, and I'm sorry for the grammatical errors !

Well, I found out this is actually a repackaged AllMax+. SO, I went out to EETools site and grabbed the software. Now, does anyone know the pinouts for the power connector?
