Does anyone have a DEC VT52 (or any of the VT5x series really) and the means to read out the 8 firmware PROMS on the rom/uart board, and/or the character ROM? The MESS team is trying to get ahold of this data for preservation/emulation. The PROM chips (according to the schematic on bitsavers: http://www.bitsavers.org/pdf/dec/terminal/vt52/MP00035_VT52schem.pdf) are 82s129 or pinout compatible with 82s129 (or maybe the open collector 82s126 version?). According to the maintenance manual (also on bitsavers: http://www.bitsavers.org/pdf/dec/terminal/vt52/EK-VT52-MM-002_maint_Jul78.p… page titled A-02) there are three different 'prom sets' of this firmware for the vt52 (and since the prom sets can be upgraded, I'm guessing they're socketed). Also, the MESS team is looking for a dump of the character generator rom; there are two versions of this rom, and the chip is an early non-jedec pinout ?mask? rom; the pinout is listed on the schematic on page 43. (It happens to have a nearly identical pinout to the MCM6830A ?eprom? used on the early heathkit et4000 non-a units) Thanks everyone for your time, and have a good day! -- Jonathan Gevaryahu AKA Lord Nightmare jgevaryahu at comcast.net jgevaryahu at hotmail.com
