They have. For example, the TMM2364P (from Toshiba) has 28 pins: http://www.trikaliotis.net/Download/datasheets/tmm2364.pdf The TMM2365P even has the programmable CS lines: http://www.trikaliotis.net/Download/datasheets/tmm2365.pdf With Toshiba, the TMM2366P is what we all know as 2364: http://www.trikaliotis.net/Download/datasheets/tmm2366.pdf Note: These are all scans I just made myself; they are from a "Toshiba MOS Memory Products Data Book" dated 10/1982. (Sometimes it pays of not to throw away such things.) In fact, these data sheets always made me surprised when I saw 2364 in CBM equipment having only 24 pins. ;) If anyone needs more info on Toshiba Memories not available anywhere else, the data book also contains info about: - Dynamic Random Access Memories (DRAM) TMM416P/D 16.384 bit, 16k x 1 TMM4164C 65.536 bit, 64k x 1 TMM4164P 65.536 bit, 64k x 1 - Static Random Access Memories (SRAM) TMM314AP/APL 4.096 bit, 1k x 4 TMM315D 4.096 bit, 4k x 1 TMM2016P/D 16.384 bit, 2k x 8 TMM2016AP (prel.) 16.384 bit, 2k x 8 TMM2016HD (prel.) 16.384 bit, 2k x 8 - CMOS Static Random Access Memories (CMOS-SRAM) TC5501P/D 1.024 bit, 256 x 4 TC5508P 1.024 bit, 1k x 1 TC5047AP 4.096 bit, 1k x 4 TC5504AP/AD 4.096 bit, 4k x 1 TC5514P 4.096 bit, 1k x 4 TC5514AP/AD 4.096 bit, 1k x 4 TC5513AP/AD 4.096 bit, 1k x 4 TC5516AP/AD/AF 16.384 bit, 2k x 8 TC5517AP/AD/AF 16.384 bit, 2k x 8 TC5517BP/BD/BF 16.384 bit, 2k x 8 TC5518BP/BD/BF 16.384 bit, 2k x 8 TC5564P 65.536 bit, 8k x 8 TC5565P 65.536 bit, 8k x 8 - Erasable/Programmable Read Only Memories (EPROM) TMM323D 16.384 bit, 2k x 8 TMM323DI 16.384 bit, 2k x 8 TMM2732D 32.768 bit, 4k x 8 TMM2732DI 32.768 bit, 4k x 8 TMM2764D 65.536 bit, 8k x 8 - Mask Programmable Read Only Memories TMM334P 16.384 bit, 2k x 8 TMM333P 32.768 bit, 4k x 8 TMM2332P 32.768 bit, 4k x 8 TMM2364P 65.536 bit, 8k x 8 TMM2365P (prel.) 65.536 bit, 8k x 8 TMM2366P (prel.) 65.536 bit, 8k x 8 TMM23256P 262.144 bit, 32k x 8 Regards, Spiro. -- Spiro R.
